10 SOUTH NIGERIAN PLANTS 
oblanceolate or oblong-obovate, mueronate leaves with short petioles, 
the connate eupuliform involuere, the staminal column antheriferous 
for 12-13 mm. of its length. 
[Petals yellow.—P. A. T.] 
STERCULIACEE. 
The collection contains a number of cauliflorous species of 
Cola. Among the novelties there are two which are of special 
interest. In Cola schizandra sp. nov. the anthers instead of 
being in a continuous ring in the male flowers are cut up into 
phalanges, and for this I venture to propose a new subgenus— 
Schizocola. Cola schizandra is allied to Cola digitata Masters, 
but I have been unable to obtain male flowers of this latter plant 
to dissect. The other novelty to which attention should be 
called is Cola gigas sp. nov. with flowers 7-8 cm. long. The 
exact affinity of the latter plant is somewhat doubtful at present, 
as it is not closely allied to any other member of the genus; it 
is evidently à most striking novelty. 
Two other novelties are Cola Talbotii and Cola Buntingii, 
both members of the subgenus Cheirocola, the latter collected by 
Mr. R. H. Bunting in Liberia. Another novelty is C. arcuata 
belonging to the subgenus Haplocola, and allied to C. flavovelutina 
K. Schum. and C. Gilgiana Engler.
