D. oliganthus seems closest to the Nigerian D. brevicaulis. Like that plant 

 it seems to produce flowering shoots that at first are suberect; later, lateral trail- 

 ing shoots appear. In habit it seems to stand midway between those species, 

 such as D. chrysanthus, that produce only trailing or scandent shoots and those 

 in which the stems are all and always erect. 



[8. Dolichos chrysanthus A. Chev. Bull. Soc. Bot. Fr. 58(Mem. 8): 164. 1912; 

 • Bak. f. Leg. Trop. Afr. 449. 1929. 

 Dolichos biflorus L. var. occidentalis Harms, Bot. Jahrb. 26: 313. 1899; Bak. f. Leg. 

 Trop. Afr. 449. 1929. 



The Index kewensis cites Dolichos occidentalis (Harms) Harms as having 

 been published in Pflanzenw. Afr. 3 (1): 677 (1915), but my colleague Mr. H. K. 

 Airy-Shaw informs me that the combination is not properly made there. 



D. chrysanthus is without doubt specifically distinct from all forms of D. uni- 

 florus. It is strange that Harms, while discussing his var. occidentalis, should 

 not have realised how distinct the fruits were, and that they were correlated with 

 well-marked vegetative characters. 



The normally trailing habit, short petioles, small leaflets and comparatively 

 large Hovers, not to mention the pods, make D. chrysanthus readily recognisable. 

 The leaflets vary in shape a good deal. 



D. chrysanthus is known from Portuguese Guinea (Espirito Santo 1439), the Ivory 

 Coast (Chevalier 22421), the Gold Coast (T. LI. Williams 390), Nigeria (Barter 967, 1591, 

 Lely 470, Dalziel 593), Ubangi-Shari (Tisserant 2930), the French Cameroons (Tessmann 

 2731), the Belgian Congo (Quarr'e 2880), Anglo- Egyptian Sudan (Schweinfurth 2251, 2375. 

 Shantz 931, Myers 9314), and Angola (Welwitsch 2209, 2210, Mrs. Faulkner A 197, A 457).l 



I am grateful to the authorities of the Museum National d'Histoire Naturelle 

 at Paris for very kindly sending on loan the type of D. chrysanthus (Chevalier 

 22427 from the Ivory Coast). 



[9. Dolichos brevicaulis Bak. in Oliv. Fl. Trop. Afr. 2: 211. 1871; Bak. f. Leg. 

 Trop. Afr. 444. 1929. 

 Confined, as far as is known, to Nigeria. 



Dolichos haumannii Harms (Bot. Jahrb. 26: 313. 1899) is rather a problem. 

 Hutchinson and Dalziel (Fl. W. Trop. Afr. 1: 410. 1928) make it a synonym of D. 

 biflorus **L." However the size alone — 12 mm. long or more — of the flowers of
