Hab. Portuguese Gongo: at an alt. of 20 m near the River Zaire (Congo), 

 Lumba, Peco, fl. Aug. n. 9115. 



A densely branched shrub of 2 m height similar to n. 9 1 1 4 (A. congolensis 

 Sprague), with whitish-green flowers; rarely flowering. 



Leaves 5 — 8X2 — 3,5 cm; petioles 5 — 10 mm long; peduncles \ — 2 cm long; 

 pedicels 0,5 — 2,5 cm long; sepals 2X1,5 mm, petals apparently about 5 mm long; 

 anthers 2 mm long with a very short filament. 



This species is related to A. corymbosus Hook. f. ex Planch. from Upper Guinea 

 and A. congolensis Sprague from Belgian Gongo, but has rather smaller flowers and 

 leaves, with the reticulation much less prominent.«
