Note
|
This species is quite unlike any other Panamanian species of Lycianthes with its very small flowers and pubescence of strigose, simple hairs. The oblique, lanceolate leaves and small, rotund minor leaves are also distinctive.

Distribution
|
reported from Honduras and Guatemala to Peru and Amazonian Brazil.

Note
|
Lycianthes storkii Mort. & Standl. from Costa Rica may be a glabrate race of this species, while L. chrysothrix Bitt. from Peru differs mainly in its greater pubescence and slightly larger flowers. Lycianthes biflora (Lour.) Bitt., a species widespread in southeast Asia, differs very little from L. amatitlanense. Its subsp. yunnanensis Bitt. is especially close to L. ama- titlanense, but it differs in its less pubescent leaves and slightly larger calyx cup. Lycianthes amatitlanense is a lowland species.
