2 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN [Vol. 9, No. 1 



I am prepared to follow Duvigneaud (I.e.) in considering S. schumanniana Gilg 

 and S. suberifera Gilg & Busse as synonyms of S. cocculoides Bak. 



Strychnos cf. lokua A. Rich. Tent. Fl. Abyss. 2: 53. 1851; Duvign. Lejeunia 13: 

 112. 1949. 



Kasungu District: Kasungu, sporadic in Brachystegia woodlands, tree to 10 

 m. high, branchlets armed with hooked thorns, deeply ringed at nodes, leaves 

 smooth and shining above, dull beneath, fruits 8-10.5 cm. in diameter, globose, 

 yellowish-green, edible, native name mateme, 1000 m., Aug. 27, 1946, 17445, 



S. lokua extends from the Senegal and the Anglo-Egyptian Sudan to South 

 Africa. It has been much misidentified with S. spinosa Lam.; for the differences 

 see Duvigneaud (I.e.).

The late Sir Arthur Hill pointed out a good many years ago (Kew Bull. 1908: 

 330. 1908) that what was called Sebaea crassifolia in the Flora of Tropical Africa 

 was quite distinct from the true South African species of that name; but in spite 

 of this warning the name has remained undisturbed in the tropics. Of the cor- 

 rectness of Sir Arthur's view there is no question. The tropical plant finds its 

 obvious place in 5". grandiflora, previously assumed to be endemic to the Trans- 

 vaal. At first I was prepared to separate the tropical material on account of the
