The other species which I refer to Atroxima are: 



2. A. Afzeliana Stapf (= Carpolobia Afzeliana Oliver in Fl. Trop. Afr. I, 

 p. 136); 3. A. macrostachya Stapf (= Carpolobia macrostachya Chod. in Bull. 

 Herb. Boiss. v., p. 117); 4. A. Zenkeri Stapf (= Carpolobia Zenkeri Gurke, 

 mss.). As the latter is still undiscribed, I add here a short diagnosis: 



4. Atroxima Zenkeri Stapf, 1. c. 



Ramuli graciles. Folia elliptico-oblonga, basi breviter contracta acuta, 

 apice abrupte acuminata, ad 5,5 poll. longa, ad 2 poll. lata, tenuiter coria- 

 cea, nervis lateralibus utrinque circiter 7 uti venarum reticulatione tenui- 

 bus indistincte arcuato- connectis: petioli subgraciles, 2 — 3 lin. longi. 

 Racemi 1 — 4 in axillis foliorum vel in ramulis nonnullis ob folia (rudi- 

 mentaria?) praemature decidua quasi in paniculas collecti, griseo-pubes- 

 centes. Flores non nisi ex alabastris noti. Fructus 0,5 poll. diametro: 

 pericarpium extus opacum, fusco-fulvum, intus nitens. 0,5 — 0.75 lin 

 crassum. Semina 3 lin. diametro. 



Kamerun: in primeval forest near Bipinde (Zenker no. 1240). 



The fruit of Carpolobia, as represented by the species C. alba D. Don 

 and G, lutea D. Don is a true berry. The globose or subglobose seeds are 

 covered with a rieh silky tomentum. and posses an ample, fleshy albumen. 

 The embryo consists of a very short subclavate radicle and two very thin 

 foliaeeous cotyledons almost as long and as wide as the seed.
