We have found ourselves unable to distinguish the Niamniam plant (Claoxylon 
Schweinfurthii, Pax) from the Monbuttu one (C. flaccidum, Pax). The species 1s 
moreover very closely allied to E. angolense, from which it is only separable by its 
longer petioles, its female racemes with more numerous flowers and its more distinctly 
2-lobed disk. 
38. E. macrophylla, Prain in Ann. Bot. xxv. 625. Shrub; twigs 
softly adpressed-pubescent ; bud-seales persistent. Leaves petioled, 
membranous, obovate-lanceolate, acuminate, base rather narrow-cuneate, 
margin slightly undulate and shallowly regularly crenate, 9-10 in. long, 
23-3 in. wide, dark green, paler beneath, at first sparingly pubescent

minute. Flowers small, in peduncled racemes ; peduncles very slender, 
silky, 3-2 in. long; pedicels glabrous, }-} in. long. Male calyx green,
