I cannot find any character by which to distinguish Am/rcBcum antennatum^ 

 Kranzl. An imperfect cultivated specimen from Mr. Christy's garden, received from 

 Liberia, belongs to the same or a closely allied species.

Near L. arcuata, Reichb. 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.
