I cannot find any character by which to distinguish Angrecum antennatum, 
Kränzl. An imperfect cultivated specimen from Mr. Christy’s garden, received from 
Liberia, belougs to the same or a closely allied species.

Lower Guinea. Princes Island, 350 ft. Newton! Barter, 2019! Also 
cultivated specimens! 
Near L. arcuata, Beicht, f., but the leaves are much narrower. The original 
specimen is in very poor condition, but has narrower, more fleshy leaves, and hence 
it remains uncertain if the other specimens referred here are identical.
