Origin/Endemic status: Endemic

Taxonomy Comments: A form with smaller fruits (3-5 cm long vs. 5-12 cm long) has been variously treated as a species [Leptoglottis chapmanii, Schrankia chapmanii] or a "recurrent fruit-form genotype" [phase brachycarpa of Isely (1973)]. This needs additional investigation.
