S. (?) ahyssinicum. Schott, was founded upon Arum ahyssinicum, A. Rich. (Tent. 

 Fl. Abyss, ii. 352), but neither Schott nor Engler appears to have seen it. From the 

 description given by A. Richard, however, it cannot belong to the genus Sauroma- 

 tuni, 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 ti vie Sauromatum, 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 as 

 they go. Engler does not describe the neuter organs, but they are very evident in 

 the specimens at Kew.
