Trujillo: Municipio Boconó, Parque Nacional Guaramacal, Páramo de Guaramacal, from summit of Boconó-Caserío de Guaramacal road to the television towers, 2900-3100 m, 13 June 2001, L.J.

Niño (holotype: PORT!; isotypes: K, MO, US-00662868!).</p><p>Diagnosis.</p><p>Dendrophthora apiculata is distinguished from congeners by its rough striate stems; minute, ca. 0.5 mm long cataphylls surrounding all nodes; leaf blades 5-20 × 3-6 mm, apex apiculate with an apiculum 0.2-0.5 mm long; inflorescences usually 1(2) per leaf axil, staminate inflorescences triseriate and pistillate ones uniseriate; flowers ca. 1 mm long; and mature fruits globose-compressed, ca. 0.8-2 × 2-3 mm when dried.</p><p>Description.</p><p>Aerial parasitic shrubs, monoecious; yellowish-green when fresh and drying dark brown. Stems woody; erect branches 20-30+ cm long; mature nodes at 2-3 cm long intervals, dichotomous, with multiple branches; coarse, longitudinal striations along principal branches with some transversal striations in basal branches (striations not visible in distal branchlets), minute papillose trichomes dispersed or absent; some lenticels present; cataphylls at nodes ca. 0.5 mm long. Leaves opposite, coriaceous; petioles winged, 2-5 mm long, indistinct; blades obovate, 5-20 × 3-6 mm, base cuneate, apex apiculate with an apiculum 0.2-0.5 mm long, margin entire; veins reticulate with midvein evident on the adaxial side when fresh and inconspicuous when dried. Pistillate and staminate inflorescences separate, alternate on the same branch or branches either predominantly staminate or predominantly pistillate, usually 1 inflorescence per leaf axil, sometimes 2; fertile internodes usually 1(2), 7-18 mm long; staminate inflorescences triseriate; peduncles simple, 1-3 mm long, rugose; cup subtending inflorescence 1.5-1.8 × 2-2.5 mm, edge of cup papillose; basal portion of staminate inflorescences with 9-12 flowers per segment (see Fig. 2C); flowers ca. 1 mm in diameter; embedded in an alveolus (sunken receptacle), emerging up to 2/3 during anthesis; pistillate inflorescences uniseriate; peduncles simple, 2-4 mm long, rugose; cup (sensu Kuijt) subtending inflorescence 0.8-1 × 1-2.5 mm, edge of cup papillose, with 3-5 flowers per segment, sometimes more (Fig. 3), flowers adjacent (sometimes touching each other); petals 3(4), triangular, glabrous. Fruits globose-compressed, ca. 0.8-2 × 2-3 mm when dried, ripening white-translucent, crowned by persistent petals.</p><p>Distribution and hosts.</p><p>Dendrophthora apiculata is known only from Guaramacal National Park (Trujillo state) between 2600-3100 m on both its northeastern and southwestern mountain slopes. This mistletoe grows in open areas of the páramo and evidently is uncommon throughout its distributional range. Its host range seems to be limited, as the only hosts recorded so far are the shrubs Cybianthus marginatus (Benth.) Pipoly ( Primulaceae), Hypericum juniperinum Kunth ( Hypericaceae), and Espeletia griffinii Ruiz-Teran &amp; López-Fig . ( Asteraceae). Interestingly, the mistletoes found so far on the first host listed were observed on lower and middle branches, while in the last one they were found at the tips of branches.</p><p>Phenology.</p><p>Reproductive individuals of Dendrophthora apiculata have been observed with flowers and fruits all year round, and the fruits seem to be an important source of food for the bird fauna present in the páramo and subpáramo habitats.</p><p>Etymology.</p><p>The specific epithet is derived from “apiculate,” which describes the minute sharp apiculum observed at the apex of leaves.</p><p>Discussion.</p><p>Dendrophthora apiculata is similar to D. lindeniana Tiegh., but the latter has stems up to 1 m long, dense papillose trichomes covering the entire plant, leaves with rounded apices with papillose edges, and the cup subtending the inflorescence is usually bifid. In contrast, D. apiculata has stems up to 40 cm long, coarsely striate stems with scarce papillose indumentum or papillae absent; leaves with a smooth margin and a persistent, minute apiculum 0.2-0.5 mm long at the apex; and a cup subtending the inflorescence that is usually whole (or rarely rounded).</p><p>Regarding their distributions, Dendrophthora apiculata is found in the Páramo de Vicuyal (ca. 2730 m) in Guaramacal National Park (Trujillo state), while D. lindeniana grows in the Páramo de Portachuelo (2860 m) ( Táchira state), near the border with Colombia. The known localities for these two species are separated one from the other by ca. 240 km.</p><p>Additional specimens examined.</p><p>Venezuela.

Trujillo: Municipio Boconó, Parque Nacional Guaramacal, trail from antennas on the summit of Páramo de Guaramacal, NE to Fila Los Recostaderos [sic, Recortaderos] (UTM: 19 369344E, 1023140N) [9.253891N, - 70.189471W], páramo and subpáramo vegetation, 2677-3100 m, 14 June 2001, L.J. Dorr 8988 with S.M. Niño &amp; R. Caracas (holotype: US-00662772!; isotype: PORT).</p><p>Diagnosis.</p><p>Dendrophthora coronata is distinguished from congeners by its stems and young branches with longitudinal parallel striations; coroniform trichomes (i.e., papillae crowned by 2-6 minute, simple hairs) covering the entire plant; small, ca. 0.5 × 1 mm cataphylls present at all nodes and sometimes found 1-2 cm above nodes on older branches; petioles 0.5-1 mm long, leaf blades 1-1.5 × 1-1.2 cm, apex rounded and margin slightly crenulate and papillose; uniseriate inflorescences with 5-9 flowers per series; and fruits globose-compressed, 2-3 × 2 mm when mature, white.</p><p>Description.</p><p>Aerial parasitic shrubs, monoecious; yellow-orange when fresh, drying blackish or dark green. Stems woody, with multiple branches, 30-45 cm long, terete, surface coarse with parallel striations, with a dense layer of coroniform trichomes covering the entire plant; mature nodes separated by 2-3.5 cm long intervals, dichotomous; cataphylls 0.5-1 mm long at nodes, found 1-2 cm above nodes as branches became older. Leaves opposite, coriaceous; petioles flattened, 0.5-2 mm long; blades orbicular to elliptic, 1-1.5 × 1-1.2 cm, base slightly cuneate, apex rounded, margin indistinctly crenulate and papillose, surface rough on both sides, veins obscure in dry leaves (Fig. 4). Inflorescences completely pistillate within a branch, occasionally with staminate flowers at the base of the inflorescence (completely staminate inflorescences not seen); 1 per leaf axil, 1-3 fertile segments, each 4-10 mm long, uniseriate, greenish when dry; peduncles simple, 6-9 mm long, cup subtending inflorescence 1-1.5 × 3-3.5 mm, almost always forked with a papillate apical edge. Flowers 3-9 per segment, 1-1.4 × 0.7-1 mm. Fruits globose-compressed, 2-3 × 2 mm, ripening white- or purplish-translucent, surface granulose, tip protruding and crowned with persistent petals.</p><p>Distribution and habitat.</p><p>This species has been found in the transition between cloud forest and subpáramo in Guaramcal. This vegetation is influenced by multiple factors including high rainfall (3200+ mm/year), elevation above sea level (2400-3100 m), as well as relative humidity (100% for most of the year) (Cuello and Cleef 2011). Dendrophthora coronata is found in these Andean/high Andean forests characterized by woody vegetation of low stature with numerous individual shrubs and small trees, and a thin understory with a carpet of thick leaf litter. The canopy can reach between 6-14 m tall, with some emerging trees that reach 16 m, among them: Ilex guaramacalensis Cuello &amp; Aymard ( Aquifoliaceae), Miconia jahnii Pittier ( Melastomataceae), Myrsine dependens (Ruiz &amp; Pav.) Spreng. ( Primulaceae), and Symplocos tamana Steyerm. ( Symplocaceae) (Cuello and Cleef 2011).</p><p>Phenology.</p><p>As with most other species of tropical mistletoe, Dendrophthora coronata can be observed bearing flowers and fruits throughout the year. Its white fleshy fruits seem to be an important food source for forest birds.</p><p>Etymology.</p><p>The species name is derived from the coroniform trichomes (i.e., papillae crowned by 2-6 minute, simple hairs) that cover the entire plant and that resemble small crowns.</p><p>Discussion.</p><p>At first sight, Dendrophthora coronata resembles D. apiculata and D. lindeniana . However, D. coronata can be readily recognized by its marked parallel striations along the stems, small, 0.5-1 mm long basal cataphylls, which sometimes are found 1-2 cm above nodes in old branches, and its dense layer of predominantly coroniform trichomes that cover the entire plant. In contrast, D. apiculata and D. lindeniana have stems sparsely covered by simple trichomes and lack basal cataphylls (or rarely have a few very small, 0.5 mm long cataphylls and then always at the nodes) (Table 1).</p><p>Additional specimens examined.</p><p>Venezuela.
