Iconography

Eichler (1868: fig. 9 - I); Kuijt (2009: fig. 89).

Notes

Psittacanthus lamprophyllus is recognized by its elliptical-ovate, lustrous leaves, with pinnate (rarely palmate) venation, axillary inflorescences with short ramifications, slender flowers with an acute apex and flower buds red, dark pink, or red at the base and yellow at the tip (Kuijt 2009; Dettke and Caires 2021). Three synonyms were recently proposed for this species: P. brachypodus Kuijt, P. leptanthus A. C. Sm., and P. redactus Rizzini (Dettke and Caires 2021). Psittacanthus lamprophyllus is distributed in French Guiana, Peru, and Brazil (Kuijt 2009; Dettke and Caires 2021), now including records from lowland forests in the Colombian Amazon Region (Fig. 3).
