10 SOUTH NIGERIAN PLANTS 



oblanceolate or oblong-obovate, muoronate leaves with short petioles, 

 the connate cupuliform involucre, the staminal column antheriferous 

 for 12-13 mm. of its length. 

 [Petals yellow.— P. A. T.] 



STERCULIACE^. 



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 (jigas sp. nov. with flowers 7-8 cm. long. The 

 exact afiinity 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 a most striking novelty. 



Two other novelties are Cola Talhotli 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.

A member of the series Integrifolite of the subgenus Haplocola, 

 Allied to C. flavo-vehitina K. Schum. and C. Gilgiana Engler, but 

 differing from both these species in the narrower leaves.
