Up to the present the genus Margaretta has been recorded 
only from East Africa, from Uganda to South Rhodesia. The 
- occurrence of an undescribed species in Northern Nigeria is 
interesting. The specimen before us bears a solitary immature 
hairy beaked fruit, borne on a long elongated peduncle (about 
10 cm.) situated opposite the flowering inflorescence between the 
topmost pair of leaves.

Takwara, 3200 ft. 4. 6. 1921, No. 110. 
This plant has been identified from the original description, 
but there is little doubt as to the correctness of the determina- 
tion owing to the striking nature of the flowers with their long 
filiform-linear lobes arising from a triangular base and the 
presence of a subulate tooth between each. Schlechter’s descrip- 
tion was drawn up from specimens collected near Kei-Buba in 
the Northern Cameroons. In the following, probably minor 
points, the Nigerian specimens differ from the details given by 
Schlechter :—the leaves are on the whole longer and broader,
