Description

Corytoplectus species are herbs or shrubs ranging from 0.5–2 m tall.[4] The stems are erect and subquadrangular, but becoming quadrangular near the top.[4] The fruit is a translucent berry with dark striate (with parallel longitudinal ridges or lines) seeds. The leaves have dark green upper surfaces with veins which are paler. The inflorescences are mostly erect.[4]

Etymology

According to Rodriques-Flores and Skog,[4] Corytoplectus derives from the Latin coryto (leather pouch) and plectus (pleated or folded).[4] They believe the name to be suitable, because, in profile, the calyces look like pleated leather pouches. However, an alternative view says that rather than deriving from the Latin coryto, the name derives from the Greek kōrys (helmet), giving "pleated helmet".[5]
