Please help me in identifying this small tree of Rubiaceae.
I thought this might be any Canthium sp. of Rubiaceae.
Fruit: c.3 cm across
Leaf: c. 8cm long; no fragrance or latex
Habitat: Dry Scrub forest and in village outskirts
Alt.: 200 - 300 m asl
Date: 06 Oct 2013
Can this be Catunaregam sp?
Pls check for Tricalysia spherocarpa of Rubiaceae
Yes it appears to be Catunaregam spinosa (Thunb.) Tirveng.
It is not Catunaregam spinosa. Leaf and fruit are different from Catunaregam spinosa.
It look like Tricalysia sphaerocarpa = Discospermum sphaerocarpum.
For me also Tricalysia sphaerocarpa = Discospermum sphaerocarpum, as identified by ...
