Usually about 7 cm. long, very often with fruits or numerous female flowers; the male 

 plant is not found. 



I did not observe this species in the immediate proximity of tlie sea and found it first at 

 a height of about 400 m. It was very common in the surroundings of Bomana (670 m.), usually 

 growing at the ends of the branches of trees; also in the neigbourhood of Bea (950 m.), on trunks. 

 This species was collected by Mr. G. Mann on the Cameroons Mountain at a height of 1200 m.
