F. Morales 2021	<div><p>Werauhia talamancana Cascante &amp; J. F. Morales, sp. nov. (Fig. 1).</p> <p>Diagnosis: — Werauhia talamancana is morphologically similar to W. brunei in its simple spicate inflorescence with smooth and lustrous floral bracts that are distichous (not secund) at anthesis. The new species differs from W. brunei in having larger flowers with longer petals (5.3–6.0 vs. 4.0– 4.5 cm) and longer stamens (4.0–5.0 vs. 3.6–3.7 cm). The lower peduncle bracts in W. talamancana are foliose and longer, compared to the non-foliose and shorter peduncle bracts of W. brunei. Also, the floral bracts of the new species are usually brown-maroon at anthesis as opposed to light green in W. brunei.</p> <p>Type:— COSTA RICA. San José: Jardín, Dota.

At the type locality, plants of this new epiphytic bromeliad are growing in the lower canopy of mixed oak forests in a very humid environment. The vegetation is classified as Very Humid Lower Montane Forest according to Holdridge’s Life Zones System (Bolaños &amp; Watson 1993). Other species in the bromeliad community were the sympatric W. ampla (Smith 1963: 497) Grant (1995a: 30), W. ororiensis (Mez 1896: 9) Grant (1995a: 44), W. pittieri (Mez 1903: 135) Grant (1995a: 33), W. rubra (Mez &amp; Wercklé 1904: 878) Grant (1995a: 47), and W. williamsii (Smith 1958: 193) Grant (1995a: 49).</p> <p>Phenology and ecology: —Flowering from February to May; fruiting from February to December. Anthesis is nocturnal and regularly a single flower opens each night, senescence occurs in the morning of the following day. Floral morphology traits (e.g., white petals and campanulate corolla; Fig. 2D) and anthesis time suggest a nocturnal pollinator, probably bats, following the chiropterophillous pollination syndrome described by Faegri and van der Pijl (1979) and related reports in some congeners (Aguilar-Rodríguez et al. 2019).</p> <p>Etymology: —The epithet refers to the mountains of the Talamanca mountain range in southern Central America, the center of diversity of Werauhia and where nearly two-thirds of thespecies occurs.</p> <p>Comments:— This new species resembles W. brunei (Mez &amp; Wercklé 1904: 865) Grant (1995a: 31) in the smooth and lustrous floral bracts that are distichous at anthesis (Fig. 2C). Also, W. brunei inhabits montane forests within the same elevation range as W. talamancana, but this new species differs by its longer petals (5.3–6.0 vs.4.0– 4.5 cm) and stamens (4.0–5.0 vs. 3.6–3.7 cm) (Fig. 2D). The brown-maroon color of the floral bracts in W. talamancana is a distinctive trait that distinguishes it from W. brunei (Fig. 2C).This qualitative characteristic is atypical among singlespicate species of Werauhia, which duringanthesis usually exhibit floral bracts with green tones and sometimes with brownish bract tips due to drying.</p> <p>Werauhia talamancana falls into Grant’s (1995a) section Werauhia,which includes plants with simple inflorescence. Following the taxonomic key provided by Morales (2003a), the new species belongs to a species group that exhibits relatively large floral bracts (3.0– 6.3 cm) with smooth and lustrous or rugose surfaces. This species group includes among others W. ampla, W. bicolor (Smith 1960: 174) Grant (1995a: 30), W. burgeri (Smith 1974: 326) Grant (1995b: 121), W. gladioliflora (Wendland 1863: 31) Grant (1995a: 31), W. macrantha (Mez &amp; Wercklé 1904: 867) Grant (1995b: 121), W. macrochlamys (Mez &amp; Wercklé 1904: 865) Morales (2003b: 65), W. osaensis (Morales 1999: 403) Morales (2003c: 15), W. tiquirensis (Morales 1999: 405) Morales (2003c: 110), and W. tonduziana (Smith 1938: 166) Grant (1995a: 35), that are very similar in appearance and difficult to keep apart from another (Morales 1999, 2003a). Molecular and floral morphology studies are necessary to elucidate the relationships between these taxa.</p> </div>	http://treatment.plazi.org/id/2773254AA33B707AFF31B8B0FAA296A5	Public Domain	No known copyright restrictions apply.
