genus in the semicircular wing of its fruit. It is perhaps reece 
allied to A. zanztbaricus, ye recedes in the pubescence of the lea 
the great ae ce of the veins on the lower surface, and the 
longer bracts and bracteoles. (G.) A. socotranus and A. orientalis, 
two species time a strong superficial resemblance to each other. 
They have small coriaceous elliptic-obovate or oblong nae i 
strongly and closely reticulated on both surfaces, and much les 
crowded dees than e omniens and A. corymbosus, in ial the 
reticulation of the leaves is similar. A. socotranus has.elliptic or 
shortly sa te elma leaves, a slender rhachis, and subulate 
racts; A. orientalis, more ~~ leaves, hairy on the lower surface, 
a stouter rhachis, and oblong bra 
urth group consists of A vy austro-caledonicus and A, excelsus. 
Both are trees. with oblanceolate leaves, silky tomentose on their 
lower surface ; the inflorescences are short, and the bracts minute 
. The racemes of A. austro- coledontage terminate the 
leafy branches, while those of A. excelsus are borne on the wood of 
the previous year. ‘The lateral veins of the leaves are more oblique 
in A. ewxcelsus than in 4. austro-caledonicus. 
All the species of weil gg of which I have seen specimens 
are accounted for in the preceding four groups. Of the remaining 
belongs to the third group, and is probably allied to A. zanzibaricus, 
judging by the figure; A. Schefieri and A. glaucescens are stated by 
Engler to be allied to A. zanzibaricus; and A. rudis is said by 
(Lo 
and longifolius Cages to A ng0 es ae none of the three pairs do 
the areas aa ed by the species overlap.
