The shape of the fruits is apparently of primary importance 
in the classification of the species, and in the present revision 
two sections have been established on this feature. Then 
several species the presence or absence of clothing hairs univ 
the articulation of the pedicel is an easily distinguishable charac- 
ter which has evidently not received sufficient attention. 
The Indian species remain as defined by Sir J. D. Hooker in 
the Flora of British India, with the exception of his ‘‘ A. Rox- 
burghiana,”’ which, there is little doubt, covers three distinct 
species, (1) A. indica, Paget: Hochr., from the Cuddapah Dis- 
trict of Madras, (2) A. glabriuscula, ~~ Juss., from Sikkim, 
Bhotan, Anat "and Yunnan, and (3) A. oryphylla, A. Juss., 
from Sylhet and the Khasia Hills. The first two species have 
amongst other differences elongate, more or less oblong or lanceo- 
late fruits, the last orbicular fruits (fig. 16), a fact not known to 
ooker for want of adequate material. 
The distribution of the genus in the Malay pig a is 
entirely confined to the Western Islands, z.e., to the Indo- 
Malayan Region as defined by Wallace (see The Malay Archi- 
nee p- 13, and physical mes and in the case of this small 
genus supports in a striking manner his conclusions, which 
were based principally on a study of the Hans of the Archi- 
pelago.
