Franchet describes the leaves “utraque facie glabra " but they are on the under 
side rather densely covered with closely appressed, minute, 6-7-radiate hairs, 
hardly visible to the naked eye. s

Wilson’s specimens show a wide range of variation. His No. 2891, with its small 
and dense inflorescences on short branchlets bearing only a few small leaves and 
sometimes nearly leafless, seems nearest to the type. All his specimens, however, 
have the flowers larger than those described by Franchet, particularly No. 2901, 
which has the petals 14 mm. long and 10 mm. broad. Sometimes, as in No. 2899, 
the flowers are borne on elongated branchlets with three pairs of well developed 
leaves. This tends to show that the type specimen does not present the normal 
development of the species, but a somewhat abnormal precocious state, as may be 
inferred from the fact that the type specimen was collected in April, while Wilson’s 
flowering specimens were all gathered in June. No. 1188 has the pubescence of 
the calyx heteromorphous, as described by Franchet, while in the other specimens 
the pubescence is homom 
P das orphous except in Delavay’ :
