In the pine region, altitude about 1,500 m, G. M. Z. 16309, 16253, representing 
two forms that future study may determine to be specifically distinct. 
Widely distributed in the Philippines at low and medium altitudes; India to

In addition to the above nine species of this genus, four additional ones, at 
present unidentified, are represented by the following specimens : C. M. Z. 16245, 
16246, both from an altitude of about 1,800 m, Copeland s. n., from the mossy 
forest at an altitude of about 2,750 m, probably representing an undeseribed 
form, and G. M. Z. 16277 from the mossy forest, a form of t|ie D. dissecta group.
