Biology:Shuaria
Shuaria is a genus of arborescent flowering plants belonging to the family Gesneriaceae. The genus is represented by just one species, Shuaria ecuadorica D.A.Neill & J.L.Clark, endemic to Ecuador.[1] The generic name refers to the Shuar indigenous group of Amazonian Ecuador where several collections were made from the forests owned by the Shuar communities.[2] Furthermore, the known range of S.ecuadorica corresponds quite closely to the ancestral Shuar territory in Pastaza, Morona-Santiago, and Zamora-Chinchipe provinces.[2]
Description
The genus Shuaria and it species Shuaria ecuadorica were described and named by David Alan Neill and John Littner Clark in 2010.[1][3] It is a multistemmed shrub or small tree, growing to 5 m, occasionally to 8 m tall.[2] It is unusual in its phyllotaxis, in which opposite and alternate leaves can occur on the same twig, typically alternate leaves at the base of a season's growth and opposite leaves at the tip.[4][5] The leaves are lanceolate, 9.5–19 cm long and 1.5–5.0 cm wide, with a 5–15 mm petiole, and a finely toothed margin.[2] The small white flowers are arranged in cymes.[2]
