A. clandestinus may be distinguished by the long nar- 
row leaves which taper in the upper portion, terminating 
in a relatively sharp point formed by the longer apical 
lobe; the shorter lobe may be present as a small tooth 
as much as 5 cm. below the extreme apex or may be en- 
tirely absent, both types of leaf sometimes occurring on 
the same plant. In the type plant, a cultivated one, the 
leaves are only about 15 cm. long, but in other speci- 
mens, for example from the Belgian Congo and the 
Gabon, they may exceed a meter in length, and all in- 
termediates have been noted. There may also be great 
variation in the fleshiness of the leaves but I have not 
been able to correlate this with other characters. 
The inflorescences in 4. clandestinus are longer and 
looser than in the species formerly included in Cephalan-
