(lecto BM [BM000895752]), Indonesia, Papua Province, Utakwa River to Mt. Carstensz, Canoe Camp.</p><p>Climber, likely epiphytic, producing both twining stems and horizontal to pendulous, straight stiff stems, latex white. Stems cylindrical, slender, 1–1.8 mm diam, sparsely pubescent, internodes 2–7 cm long. Roots not observed. Leaves: petiole terete, channelled above, 1.5–2.5 by c. 0.5 mm, pubescent; lamina lanceolate, chartaceous, 18–45(–70) by 6–12(–15) mm, apex acuminate, base rounded or attenuate, glabrous; venation pinnate, midrib depressed on adaxial surface, secondary veins 6–10 each side. Basal colleters one, narrowly conical, c. 0.3 mm long. Inflorescence one per node, positively geotropic, pseudo-umbelliform, consisting of 20–30 flowers; peduncle extra-axillary, terete, 14–40 by c. 3 mm, older peduncles forming a rachis from previous flowerings, pubescent; pedicels filiform, 18–23 by c. 0.3 mm, glabrous. Calyx c. 2 mm diam; lobes narrowly deltate, 0.8–1 by c. 0.35 mm, apex rounded, glabrous. Basal colleters one at each calyx lobe sinus, ovate, c. 0.2 mm long. Corolla rotate, star-shaped, 12 –15 mm diam when flattened; tube c. 3 mm long, cream to pale yellow or pink, outside glabrous, inside pubescent; lobes deltate, 5–6 by 4–4.5 mm, apex acuminate, cream to pale yellow or pink, outside glabrous, inside densely pubescent. Corona staminal, central part conical, surrounded by spreading or downcurved lobes, 2.3–2.6 mm high, 3.5–4.5 mm diam; lobes with an inner process erect, oblong, c. 1.5 by 0.5 mm, apex rounded, pale yellow, apically sometimes red, and a spreading outer process, oblong, 1.5– 1.7 by 0.7–0.8 mm, apex rounded, cream to yellow, with basal revolute margins. Pollinia oblong, 380–220 by 130–150 µm, with pellucid margin; corpusculum oblong with a central constriction, 150–170 by 80–90 µm; caudicles oblong, c. 100 µm long. Ovary narrowly conical, c. 1 by 0.2 mm, glabrous. Fruit and seed not observed.</p><p>Distribution — Known from three localities in Indonesia, West Papua Province: the type collection from Utakwa River, one specimen from Bomberai Peninsula, and one unvouchered record from Mimika regency (near Timika town) in Papua province (Imran, pers. comm.).</p><p>Habitat &amp; Ecology — Unknown, it appears to be a lowland species, found along rivers.</p><p>Conservation status — Data Deficient (DD; IUCN 2012). Known only from the type specimen collected 106 years ago, a second collection from 59 years ago and a recent unvouchered collection, more collections and habitat data is needed before the conservation status can be assessed .</p><p>Specimens examined. INDONESIA, West Papua Province, Bomberai Peninsula, Kwafa, Sjuga-Wagura area, 26 Apr. 1963, BW (V. W. Moll) 13035 (L [L0834583]) .</p><p>Note — The protologue of H. leucantha only mentions the type collection as ‘Canoe camp 500ft’ (Moore 1916). The only original material available for typification is Boden Kloss s.n. (BM [BM000895752]), which is therefore designated as the lectotype for the name. The shape of the corona of H. leucantha is uncommon among New Guinean species, consisting of a central conical portion formed by the inner lobe processes, surrounded by oblong spreading or downcurved outer processes. This is only partially visible in the small buds present on the type specimen. There the corona lobes have an erect inner process of c. 1 mm tall and a basally attached outer process ovoid, c. 0.3 mm long. Hoya leucantha is somewhat similar to Hoya patella Schltr. in corona morphology, as both species have erect, oblong inner corona processes and spreading narrow, oblong outer corona lobe processes, but they can be separated on peduncle length, number of flowers per inflorescence and corolla type and size (peduncle 1.4–4 cm long, 20–30 flowers per inflorescence, corolla rotate, 12–15 mm diam in H. leucantha vs peduncle 2– 3 mm long, 1– 2 flowers per inflorescence, corolla broadly campanulate, 3–4 cm diam in H. patella).</p></div>	https://treatment.plazi.org/id/039D5C15BD143C7C6A73ECC94ACEF886	Public Domain	No known copyright restrictions apply.

In New Guinea it is only vaguely similar and likely unrelated to a group of species that include H. microphylla, H. oxycoccoides . H. pulchella and H. venusta Schltr. They are all delicate epiphytic climbers with small leaves, wiry stems and snow-white flowers with red to maroon centres. Hoya pulchella has elliptic to ovate leaves and a broadly campanulate corolla of c. 2.5 cm wide, and it is therefore more similar to H. domaensis, while the other species have a more rotate corolla of c. 2 cm wide; H. microphylla has lanceolate to ovate leaves of 1–2 cm long; H. venusta has stouter stems and peduncles, and larger lanceolate leaves (up to 5 cm long); H. oxycoccoides has 1–1.5 cm long round leaves.</p><p>d</p></div>	https://treatment.plazi.org/id/039D5C15BD143C7A692AE9F74AF9FBB7	Public Domain	No known copyright restrictions apply.

The corona morphology of H. krusenstierniana subsp. krusenstierniana is quite variable (Simonsson Juhonewe &amp; Rodda 2017: f. 16, 17) and therefore unlikely to be a good character for taxon separation, even though it appears that the centre of the corona of H. krusenstierniana subsp. laticorolla is more conical compared with specimens of H. krusenstierniana subsp. krusenstierniana . This feature is, however, often obliterated in herbarium specimens.As mentioned in the diagnosis, the reliable characters to separate the two subspecies lie in the corolla and corpusculum size. Since the two taxa occupy the same type of habitat and their morphological variation is still not well known we decided to consider the new taxon a subspecies of H. krusenstierniana rather than a new species.</p></div>	https://treatment.plazi.org/id/039D5C15BD103C786A70EB194AF8F8A1	Public Domain	No known copyright restrictions apply.

Locally common in some of the forest remnants. It was also sighted on a Ficus sp. tree in a garden near Alotau town.</p><p>Conservation status — Critically endangered CRB1a,b(iii) (CR; IUCN 2012). This species appears to be common at the type locality, but it may be locally endemic as it has not been recorded elsewhere in Papua New Guinea, neither from herbarium specimens nor during the recent extensive fieldworks. Much of Milne Bay Province’s lowland rainforest has been, or is being, logged (Shearman et al. 2009) and the type locality is not inside a protected area, and surrounded by human settlements and by Alotau town, so may be lost in the near future.</p><p>Specimens examined (paratypes).

MR426 (SING) .</p><p>Notes — Hoya liddlean a is most similar to the widespread (yet endemic to New Guinea) H. onychoides because both species have inflexed ‘claw-like’ corolla lobes and oblong corona lobes. They can be easily separated because the inner surface of the corolla of H. onychoides is glabrous (except a few scattered hairs inside at the base of the staminal corona and along margins) while in H. liddleana it is pubescent throughout inside.

Both taxa are widespread in the mountains of New Guinea and cannot be distinguished when not in flower, but upon seeing living materials we noticed that H. lucida has flattened buds and more broadly campanulate corollas that are thinner and flexible upon touch, while the buds are rounded and the corolla is stiffer and succulent in H. calycina subsp. glabrifolia . The scent from cultivated specimens from Morobe and Madang is similar to that of Lily of the Valley ( Convallaria majalis L., Asparagaceae).</p></div>	https://treatment.plazi.org/id/039D5C15BD113C74692AE9DE4AE3FBC3	Public Domain	No known copyright restrictions apply.

The name refers to the exceptionally diverse rainforests of</p><p>New Guinea which are sometimes called Paradise forests.</p><p>All measurements are from live material, measurements in brackets indicate dry size.</p><p>Epiphytic climber with white latex in all vegetative parts. Stems up to 5 m long, cylindrical, 1–2 mm diam, sparsely pubescent, green; older stems lignified, up to 4 mm diam, glabrous, greyish brown, often sending horizontal flowering branches with densely spaced internodes of 1–2 cm long, while the main climbing stems often have 5–15 cm long internodes. Adventitious roots numerous, scattered along the stems. Leaves: petiole 3–6 by c. 1 mm, sparsely pubescent turning glabrescent, lamina elliptic-lanceolate, coriaceous, 5–8 by 1.5–3 cm, medium green on both surfaces, apex caudate, base round to attenuate; venation pinnate, midrib depressed on adaxial surface, secondary veins more or less obscure, glabrous. Basal colleters often missing, when present one, ovoid, 0.3–0.4 mm long.

Calyx c. 6 mm diam; lobes acute, c. 1.5 by 1 mm, apex acute. Colleters not observed. Corolla campanulate, c. 3 cm diam in natural state (4.5–5 cm when flattened or c. 1.5 cm when dry in natural state), creamy white with very slight pinkish or yellowish hue, outside glabrous, inside glabrous except for a pubescent ring beneath the corona and the entire margin of corolla covered with stiff, brittle, c. 3 mm long hairs; tube c. 3 cm diam (c. 1.5 cm diam), c. 1 cm deep; lobes broadly triangular, c. 1.4 by 1.6 cm (7–9 by 8–10 mm).

Ovary conical, c. 2.5 mm long, glabrous. Fruit and seed not observed.</p><p>Distribution — This species was first collected in 2011 during an expedition along the Black River, the type locality, and has not been recorded elsewhere during other expeditions in Papua New Guinea. In 2021 we received photographic records of two additional collections from Mimika regency in Indonesian Papua province (Mt Timika area), indicating a wider distribution area (Imran pers. comm.). The species may be more common in southwest New Guinea, which is still much unexplored.</p><p>Habitat &amp; Ecology — An epiphytic climber in lowland primary riverine forest, often growing near the ground or near streams on trees and shrubs. At the type locality it was not observed in taller trees or sunnier and drier spots, only in shade or filtered sunlight. Locally common at the type locality.</p><p>Conservation status — Data Deficient (DD; IUCN 2012). This species has only been vouchered at the type locality where it appears to be locally common. Much of Papua New Guinea’s Western Province’s lowland rainforest has been, or is being, logged (Shearman et al. 2009) and the type locality is not inside a protected area and may be lost in the near future. The two records in Mimika regency, Papua Province, suggest that H. paradisea may be much more widespread and it is possible that it might be found in Lorentz National Park. The conservation assessment will need to be updated once more collections become available.</p><p>Notes — It is the only Hoya species in New Guinea having c. 3 mm long and very brittle hairs along the margins of the campanulate flowers, that move with the slightest air movement. It is here compared with H. juhoneweana subsp. juhoneweana because of the similarities in the corolla shape (campanulate) and in the small corona in comparison to the size of the corolla. It is not compared with H. juhoneweana subsp. lindforsiana Simonsson &amp; Rodda, because this subspecies has a rotate corolla. The similarities with H. juhoneweana subsp. juhoneweana, however, do not automatically make it a subspecies of H. juhoneweana and the two taxa may not be closely related as other characters such as the leaf orientation and pubescence are quite different. They occur in different habitats, H. paradisea growing in the lowlands, H. juhoneweana subsp. juhoneweana from above 1300 m. Outside of New Guinea, H. devogelii Rodda &amp; Simonsson also has campanulate flowers with long (c. 2 mm long) hairs on the corolla lobes. The two species can be separated on leaf shape, texture and size (linear-lanceolate, fleshy, 10–15 by 1–2 cm in H. devogelii and elliptic-lanceolate, coriaceous, 5–8 by 1.5–3 cm in H. paradisea) and corona morphology (stipitate, round when observed from above in H. devogelii; sessile, distinctly 5-lobed in H. paradisea). When not in flower, H. paradisea can be confused with many other New Guinean species with similar plain green, coriaceous leaves, for example H. apoda S.Moore, H. evelinae Simonsson &amp; Rodda, H. leucantha S.Moore, H. oreostemma Schltr., and H. solaniflora Schltr. Their flowers show a great diversity in both size, shape, colour and orientation, but none of them have corolla lobes with 3 mm long hairs. The flowers of H. paradisea last about two nights only, and emit a very pleasant and noticeable scent during the night similar to a mixture of rose and citrus, reminding of the scent of rose geranium ( Pelargonium graveolens L’Hér. hybrids, Geraniaceae).</p></div>	https://treatment.plazi.org/id/039D5C15BD1C3C75692AEA7E4BA1F9CE	Public Domain	No known copyright restrictions apply.

Other species with deeply lobed corollas are H. exilis Schltr. and H. oreostemma Schltr., but their corolla lobes are reflexed (vs inflexed in H. tarikuensis). Hoya pulleana (published here) has deeply lobed corollas with inflexed corolla lobes just like H. tarikuensis but the leaves of H. pulleana are ovate to round, 8–16 by 5–12 mm (vs elliptic-lanceolate, 4–15 by 1.5–7 cm in H. tarikuensis).</p></div>	https://treatment.plazi.org/id/039D5C15BD1B3C736A73E8534A6CF94C	Public Domain	No known copyright restrictions apply.

Versteeg 1235 (holo L [L0834580]; iso BO [BO0110494]), Indonesia, Papua Province, Zandvoort-Sabang, 15 June 1907 .</p><p>Etymology. Named after its type locality, Sungai Unir (formerly Lorentz river). The two duplicates of the type collection were labelled in 1991 as ‘ Hoya greenii P.Forster &amp; Liddle ms.’, a nomen nudum, and likely intended to name the species after Ted Green of Kaaawa, USA.Another species from the Philippines, H. greenii Kloppenb. was named after him in 1995.</p><p>Climber, likely epiphytic, latex colour unknown, all vegetative parts glabrous. Stems cylindrical, slender, 2–4 mm diam, internodes 3–12 cm long. Roots not observed. Leaves: petiole terete, channelled above, 10–25 by 1.5–2 mm; lamina elliptic to ovate, chartaceous, 8–15 by 4–6 cm, apex acuminate-cuspidate, base acute; venation pinnate, midrib depressed on adaxial surface, secondary veins 4–8 each side. Basal colleters one, broadly triangular, 0.5–0.8 mm long. Inflorescence one per node, tropism unknown, likely positive, pseudo-umbelliform, consisting of 6 or more flowers; peduncle extra-axillary, terete, 2–8 cm by 1.5–2.5 mm, older peduncles forming a rachis from previous flowerings, glabrous; pedicels filiform, 28–33 by c. 0.8 mm, glabrous. Calyx c. 4 mm diam; lobes deltate, 1.3–1.6 by c. 1 mm, apex acute, glabrous. Basal colleters scattered along the inner base of the calyx lobes, globose, c. 0.2 mm long. Corolla rotate, 20–22 mm diam when flattened, creamy greenish-yellow; tube c. 5 mm long, outside glabrous, inside pubescent, with shorter hairs towards the centre; lobes elliptic-ovate, 8–10 by 6–8 mm, apex acute, margin reflexed, outside glabrous, inside densely pubescent. Corona staminal, 1.5–2 mm high, 8.5–10 mm diam, creamy yellow with pink centre; lobes lanceolate, 5–5.5 by 1.9–2.1 mm, inner process oblong, covering the style head and joining in the middle, c. 1.5 mm long, outer processes spreading, apex truncate, with basal revolute margins. Pollinia lunate, 600–700 by c. 300 µm, with pellucid margin; corpusculum oblong, c. 330 by 140 µm; caudicles linear, c. 150 µm long. Ovary conical, c. 1.5 mm long, glabrous. Fruit and seed not observed.</p><p>Distribution — Only known from one location in Indonesia, Papua Province, Sungai Unir (formerly Lorentz river).</p><p>Habitat &amp; Ecology — Based on the label data it was collected in a forest habitat with bamboos.</p><p>Conservation status — Data Deficient (DD; IUCN 2012). Hoya unirana is known only from the type specimen collected 115 years ago .</p><p>Note — Hoya unirana is most similar to the two lowland species H. chloroleuca and H. tarikuensis (described above), in having thin leaves that can grow to&gt; 10 cm long, with acute bases, and having inflorescences with at least 6 flowers, but can be distinguished in the corolla size (c. 2 cm in H. unirana), compared to 0.8–1.2 cm in H. chloroleuca and H. tarikuensis . Hoya subglabra Schltr. also has similar leaves and rotate flowers of c. 2 cm diam, but it grows only at 400–1500 m altitude.</p></div>	https://treatment.plazi.org/id/039D5C15BD1B3C71692AE8FF4AF9FE2E	Public Domain	No known copyright restrictions apply.
