Nombre Vulgar y Usos
Tipo y Observaciones
Material Tipo: Basónimo: Cleome houtteana Schltdl.
Observaciones: Phenology.- Tarenaya houtteana flowers and fruits throughout the year.
Uses.- Tarenaya houtteana is cultivated as an ornamental around the world.
Vernacular name.- Feijão-de-venda (D. A. Folli 2554), sete-marias, mussambê, mussambê-de-espinho,beijo-fedorento (Costa-e-Silva, 2000).
Discussion.- Tarenaya houtteana has been referred to in the literature as T. hassleriana (Costa-e-Silva, 2000; Iltis & Cochrane, 2007, 2015; Soares Neto et al., 2019, 2020), despite the recognition by Iltis (1952) that Cleome houtteana had priority. Furthermore, T. houtteana has been wrongly identified as T. spinosa in many herbaria. Both species have the same subshrub habit, armed petioles, 5- to 7-foliate leaves and very similar floral features that overlap when compared. Nevertheless, T. houtteana is native to South America, while T. spinosa occurs from Mexico to Venezuela and Colombia, and in the West Indies. Tarenaya houtteana can be distinguished by its pink to purple, rarely white, oblong to lanceolate petals, 18–20 × 7–8 mm (vs. white oblong-elliptic, 7–15 × 3–5 mm in T. spinosa), filaments 50–70 mm long (vs. 21–33 mm long), anthers 8–11 mm long (vs. 6–9 mm long), and a gynophore 40–80 mm long (vs. 15–30[–35] mm long).
