 3 (1906) 337, t. 73. 



A tree bearing elliptical leaves. Leaves cuneiform at the base, 

 rather sharply obtuse at apex, acumen short ; petiole 8 mm. to 9 mm. 

 long, lamina 5 cm. to 12 cm. long by 1.5 cm. to 4.5 cm. wide; lateral 

 veins 7 to 8, anastomosing in arches before reaching the margin ; 

 glands axillary, small or not appearing on upper surface; opening by 

 an irregular slit, often oval, at angle of veins; stipules w^idely tri- 

 angular, slightly pointed; bracts foliaceous, linear, 4 mm. long. 

 Flowers arranged in 2 to 3 axillary cymes of i to 2 flowers each, 

 usually solitary; cyme peduncle short, more or less flattened, lightly 

 attached to fruit and bearing i to 2 superposed calycules; flowers 7 

 to 8-merous; lobes 12 mm. to 15 mm. long, tube about 10 mm. long. 

 Fruit 14 mm. long by 10 mm. in diameter, and bearing a prominent 

 I mm. disk at the summit ; disk very shortly contracted, usually 

 not exceeding the calyculus. When two fruits are found subtended 

 by the same calyculus, one has a much longer pedicel than the other. 



Diagnostic Characters of the Variety: — Prominent anastomosis 

 of the leaf-veins. Pedicel scarcely exceeding the calyculus. Bracts 

 linear, foliaceous, divergent, persistent below the fruit, and giving 

 the fruiting glomerule a compact appearance. 



Geographical Distribution: — Stanley-Falls; Batekalela; Island of 

 Lualaba. 



History: — This variety was collected at Stanley-Falls and on 

 the island of Lualaba in 1896, and at Batekalela in 1904. Laurent 

 mentions this variety as indigenous in the above localities; but it was 

 not described authentically until 1906. 



Use: — As a local substitute for C. arahica L.
