S. (?) abyssinieum, Schott, was founded upon Arum abyssinicum, A. Rich. (Tent. 
Fl. Abyss. ii. 352), but neither Schott nor Engler appears to bave seen it. From the 
description given by A. Richard, however, it cannot belong to the genus Sawroma- 
tum, and I have little doubt that it is a species of Amorphophallus, to which genus I 
have referred it. 
The plant above described is a true Sawromatum, and is scarcely distinguishable 
from the Indian S. guttatum, Schott; the only difference appears to be that the 
neuter organs are rather shorter, and very much less clavate, being very slightly 
thickened at the tips. My description is chiefly based upon a cultivated specimen, 
grown from a tuber sent from Nyasaland by Mr. J. Buchanan to Mr. J. O’Brien, of 
Harrow, which quite agrees with other specimens at Kew from Eritrea, so far a5 
they go. Engler does not describe the neuter organs, but they are very evident in 
the specimens at Kew.
