Schwirkowski 950 (MBM!, FPS1271!).</p> <p>Distribuition and habitat:— Chaetogastra cordeiroi occurs in the states of Santa Catarina and Paraná (Figure 1A), between 800–1.600 meters, in montane and high-montane Atlantic Rain Forest, High-altitude Grasslands, and Araucaria Forest. The populations of this species are usually large, with several individuals.</p> <p>Phenology:— Flowering and fruiting from December to April.</p> <p>Conservation status:— This species can be considered Vulnerable, according to IUCN’s category A2 (2012). The Area of Occupancy is about 1.216.000 km 2, and the Extent of Occurence 49.445.0304 km 2. Some occurrence sites have been turned into housing developments, mostly in Balsa Nova, Campo Largo, Piraquara and Quatro Barras, all part of the metropolitan region of Curitiba, the largest city in Paraná. Other areas have been replaced with pastures or species of Pinus Linnaeus (1753: 1000), mostly in “Serra de Araçatuba” (25°53’21.31”S- 48°57’24.98” W) and “Serra do Quiriri” (26°0’57.62”S- 48°56’39.03”W), where the largest populations of C. cordeiroi are.</p> <p>Etymology:—The epithet honors the collector of the type, Juarez Meyer Cordeiro, who has been collecting plants, mostly in southern Brazil region, since when he started working at the “Museu Botânico Municipal de Curitiba”, in 1981. As a disciple of Gert Hatschbach, he now works at the herbarium, organizing and determining specimens. This is a small tribute to Juarez, and a way to recognize the importance of his work.</p> <p>Affinities: — Chaetogastra cordeiroi is similar to Tibouchina gracilis by the monopodial growth, elliptic-lanceolate leaves, sericeous-dendritic hypanthium, and large petals. Chaetogastra cordeiroi differs from T. gracilis by the differences pointed in the diagnosis, and also by strigose branches, with appressed trichomes in C. cordeiroi, vs. hirsute, with erect trichomes in T. gracilis. Chaetogastra cordeiroi is also similar to Tibouchina debilis (Chamisso 1834: 449) Cogniaux (1885: 401) due to the monopodial growth, elliptic-lanceolate leaves, lax inflorescences, and the antesepalous stamens with long pedoconnectives, 2.5–3.3 mm long in C. cordeiroi, and 2.3–2.7 mm in T. debilis. They differ by the pendulous leaves in T. debilis and erect on C. cordeiroi, and also by the dendritic-sericeous hypanthium in C. cordeiroi, vs. dendritic-setose in T. debilis. Tibouchina rupestris Cogniaux (1891: 1176) is also similar to C. cordeiroi due to the monopodial growth, elliptic-lanceolate leaves and the antesepalous stamens with long pedoconnectives, 2.5–3.3 mm long in C. cordeiroi, and 2.5–3.2 mm long in T. rupestris. They differ by the dendritic-sericeous hypanthium with appressed trichomes in C. cordeiroi, and setulose hypanthium with curved trichomes in T. rupestris and also by the abaxial surface of the bracteoles, which is moderately dendritic-strigose in C. cordeiroi and glabrous in T. rupestris.</p> </div>	https://treatment.plazi.org/id/AA187839D2612F74D5C3F14F7DE86DFC	Public Domain	No known copyright restrictions apply.

The Area of Occupancy is about 5.000 km 2, and the Extent of Occurence 211.025 km 2. Only a few populations occur inside conservation units; fires are frequent in these regions and may be threatening these populations.</p> <p>Etymology:—The epithet refers to the thick consistency of the leaves, which is an uncommon feature in other species of the genus.</p> <p>Affinities: — Chaetogastra crassifolia is similar to Tibouchina cerastiifolia var. hirtsuta due to the sympodial growth, hirsute branches, elliptic leaves and the antesepalous stamens with long pedoconnectives, 2.2–3 mm long in T. cerastiifolia var. hirsuta and 2–3 mm long in C. crassifolia. Chaetogastra crassifolia differs from Tibouchina cerastiifolia var. hirtsuta by the differences pointed on the diagnosis. Tibouchina urbanii Cogniaux (1888: 682) is also similar to C. crassifolia due to the sympodial growth, vinous hypanthium, chartaceous and ovate leaves, with a conspicuous petiole 2.2–5.3 mm long in T. urbanii and 3–6.5 mm long in C. crassifolia. Chaetogastra crassifolia differs from T. urbanii by the chartaceous leaves and antesepalous stamens with 2–3 mm long pedoconnectives, vs. membranaceous leaves and 0.4–0.8 mm long pedoconnectives in the antesepalous stamens of T. urbanii. Chaetogastra crassifolia is also similar to Chaetogastra cristaensis (see below) due to the sympodial growth, chartaceous leaves, ovate leaf blade, wide and large hypanthium, 7–9.6 × 3–4.4 mm in C. crassifolia and 5–7 × 3.4–5 mm in C. cristaensis. Chaetogastra crassifolia differs by the margin of the leaves with trichomes 1.4–3 mm long (vs. 3–6 mm long in C. cristaensis), and also by the antesepalous stamens with 2–3 mm long pedoconnective (vs. 1–1.2 mm long in C. cristaensis). It is also similar to Tibouchina debilis by the inflorescences with lax, predominantly pentamerous flowers, and the antesepalous stamens with long pedoconnectives, 2.3–2.7 mm in T. debilis and 2–3 mm long in C. crassifolia. As in T. debilis, the leaves in C. crassifolia can be seldom conduplicate. Chaetogastra crassifolia differs from T. debilis by the sympodial growth, elliptic or ovate leaves with petioles, 3–6.5 mm long vs. monopodial growth, elliptic-lanceolate leaves with short petioles, 0.5–2.2 mm long. Some specimens of C. crassifolia were included in T. debilis in the taxonomic treatment of Tibouchina for the state of Paraná (Meyer 2010), but with a note suggesting that they might belong to an undescribed species.</p> </div>	https://treatment.plazi.org/id/AA187839D2652F7BD5C3F0A97E7B6910	Public Domain	No known copyright restrictions apply.

Ferreira &amp; V. Ariati 119 (MBM!).</p> <p>Distribuition and habitat:— Chaetogastra cristaensis occurs only in the state of Santa Catarina (Figure 1C), between 870- 1.000 m, in upper montane Atlantic Rain Forest and High-altitude grasslands at the “Serra do Quiriri” (26° 4’40.79”S- 48°55’43.66”W), near the peak of “Monte Crista” (Figure 7E), with small populations.</p> <p>Phenology:—Flowering and fruiting from January to March.</p> <p>Conservation status:—This species can be considered Critically Endangered according to IUCN’s category A2 (2012). The Area of Occupancy is around 480 km 2, and Extent of Occurence 1.028 km 2. The only known population comes from an unprotected area, with frequent timber removal for use in bonfires; the area has camping sites that are expanding, and there are fire reports related to them.</p> <p>Etymology:—The epithet is refers to the locality of “Monte Crista”, only site of occurrence until the moment.</p> <p>Affinities: — Chaetogastra cristaensis is similar to Tibouchina urbanii due to the sympodial growth, ovate leaf blades, and the antesepalous stamens with short pedoconnectives, 0,4–0,8 mm in T. urbanii, and 1–1.2 mm long in C. cristaensis. Chaetogastra cristaensis differs from T. urbanii by the differences pointed in the diagnosis. Chaetogastra cristaensis is also similar to Chaetogastra crassifolia (see comments under this species).</p> </div>	https://treatment.plazi.org/id/AA187839D26A2F7FD5C3F41478126910	Public Domain	No known copyright restrictions apply.

Kinupp 2904 (ICN!).</p> <p>Distribuition and habitat:— Chaetogastra riograndensis occur only in the state of Rio Grande do Sul (Figure 1D), in Grasslands, generally restricted to wet places along river banks (Figure 10D). Although with a restricted range, the populations of this species are large, with several individuals.</p> <p>Phenology:—Flowering and fruiting between February to April.</p> <p>Conservation status:—This species can be considered Critically Endangered according to IUCN’s category A4 (2012). The Area of Occupancy is around 2.450 km 2, and the Extent of Occurence 10.0149 km 2. Some populations are in unprotected areas, where the original vegetation has been replaced with Pinus spp., agriculture and pastures. Even the populations located inside the “Parque Estadual do Rio Tainhas” (29°5’35.32”S- 50°21’51.31”W) are threatened by the plantations of Pinus spp. in adjacent areas.</p> <p>Etymology:—The epithet is refers to the state of Rio Grande do Sul, to which this species is endemic.</p> <p>Affinities: — Chaetogastra riograndensis is similar to T. saxicola due to the sympodial growth, lanceolate leaves and antesepalous stamens with long pedoconnectives, 2–3.2 mm long in T. saxicola, and 2.3–2.9 mm long in C. riograndensis. Chaetogastra riograndensis differs from T. saxicola by the differences pointed in the diagnosis. It is also similar to Tibouchina nitida (Graham 1831: 186) Cogniaux (1885: 404) due to the narrow leaf blade, tetramerous flowers and antesepalous stamens with long pedoconnectives, 2–2.3 mm in T. nitida. Chaetogastra riograndensis differs by the color of the leaves in dry specimens, green in C. riograndensis and brown in T. nitida. Tibouchina nitida have leaves that are always glabrous (adaxial surface), while in C. riograndensis they can be glabrous or moderate to sparsely strigose, with trichomes distributed on the whole surface or restricted to its central-basal portion. In Chaetogastra riograndensis, the abaxial surface of the bracteoles is glabrous, while in T. nitida they are sparsely setulose.</p> </div>	https://treatment.plazi.org/id/AA187839D26E2F63D5C3F40D7C916A8C	Public Domain	No known copyright restrictions apply.
