Bitterwood Tree
Picrasma
A genus of deciduous trees and shrubs known for their extremely bitter bark and medicinal …
Inhabiting the high-altitude cloud forests of the Andes, Lozanella permollis stands as a notable representative of its genus. This wild species thrives in damp, montane environments across several South American nations, contributing to the rich biodiversity of the region.
Botanists Ellsworth Paine Killip and Conrad Vernon Morton first described this taxon in 1931. Its presence is documented in countries such as Colombia, Ecuador, Peru, Venezuela, and Bolivia.
Characteristics of this species include its distinctively soft, velvety pubescence on the foliage, which is reflected in the specific epithet permollis. The leaves are arranged in an opposite pattern along the stems, featuring serrated margins and prominent venation.
Small, inconspicuous flowers develop in axillary inflorescences. The plants are dioecious, meaning male and female reproductive structures occur on separate individuals, a trait typical for this lineage.
Unlike many related plants that exhibit alternate leaf arrangement, members of the genus Lozanella possess opposite leaves. This morphological divergence is a key identifying marker for taxonomists working in the Neotropics.
The species name permollis translates to 'very soft' in Latin, highlighting the dense, velvety hairs that cover the undersides of the leaves.
