We have found ourselves unable to distinguish the Niamniam plaiit {Claoxylon 

 Schweinfurthii, Pax) from the Monbuttu one {C.Jlaccidum, Pax). The species is 

 moreover very closely allied to E. angolense, from wliicli it is only separable by its 

 longer petioles, its female racemes with more numerous tiowers and its more distinctly 

 2-lobed disk. 



38. E. macrophylla, Prain in Ann. Bot. xxv. 625. Shrub; twigs 

 softly adpressed-pubescent ; bud-scales persistent. Leaves petioled, 

 membranous, obovate- lanceolate, acuminate, base rather narrow-cuneate, 

 margin slightly undulate and shallowly regularly crenate, 9-10 in. long, 

 2|-8 in. wide, dark green, paler beneath, at first sparingly pubescent 

 especially on the nerves, at length glabrous above, beneath uniformly 

 softly adpressed-pubescent on the nerves and nervules ; petiole sparingly 

 adpressed-pubescent, J-} in. long ; stipules unmodified, hyaline-scarious, 

 minute. Flowers small, in peduncled racemes; peduncles very slender, 

 silky, J-| in. long ; pedicels glabrous, \-\ in. long. Male calyx green, 

 glabrous, globose in bud ; lobes 4, membranous. Stamens 24 ; outer 

 10, the rest central ; filaments much shorter than the anthers ; glands 

 minute, hirsute, rhomboid, all inter-staminal. Female flower and fruit 

 not seen. — Claoxylon macrophyllum, Prain in Kew Bulletin, 1911, 95.

 Mildbraed, 2197 ! 



A very distinct species, most resembling jE. Dewevrei and E.hisjnda but readily 

 distinguished trom both by the sbape of the leaves and the absence of bispid liairs. 

 Till female flowers and Iraits are available its precise affinity must, however, remain 

 doubtfuL 



39. E. Dewevrei, Prain in Ann. Bot. xxv. 026. Shrub 3-5 ft. 

 high ; twigs hispid with yellow hairs ; bud-scales persistent. Leaves 

 short-petioled, membranous, ovate, rather abruptly acuminate, base 

 rounded, margin rather closely denticulate or crenate, 4-5 in. long, 

 l|-2 in. wide, dark green, grey beneath, sparingly hispid on the nerves 

 and finely verrucose above, densely hispid on the nerves and elsewhere
