Urandra apicalis, Thw.—C. P. No. 2569 in Herbario Peradeniensi. ~ 
A very large tree, rather common in some forests of the Central 
Province, at an elevation of from 1000 to 2000 feet. The leaves are 
coriaceous, perfectly smooth, bright green above, paler beneath, 4-6 
inches long by 2-3 inches wide, ovate-lanceolate, rather suddenly acu- — 
minate and narrowed towards the petiole, which is grooved above and 
from } to $ inch in length. Petals purple, with the apical half greenish. - 
Drupe oblong, pointed, 14 inch long and 10 lines wide, green, more 
or less tinged and blotched with purple, the upper half white. 
The Kandians call the tree Oorookannoo-gass. | 
This species is closely allied to Stemonurus, Bl. (Gomphandra, Wall.), - 
but differs in all its flowers being fertile, in its small, not pulvinate 
stigma, and in the structure of its ripe fruit. The habit of the plant 
is also distinct, and the flowers and fruit are much larger than in u 
species of Stemonurus occurring in the island. As regards the latter 
genus, I may remark that I am acquainted with but two — =
