Rubiaceae Tree for identification 261113MK001 : Attachments (3). 7 posts by 4 authors.
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 …

id please

I don’t really think Mussaenda can be classified based on out of focus  pictures of leaves ( and that too without measurements etc, surface pictures) and NO PICTURES OF THE so called flowers and the decorative “leaf guards”.
I searched for a while there is no key to classify Mussaenda with pictures of fruits only…. though some of the fruits like in m. frondosa are small and uniquely shaped.
so lets wait till it flowers for classification???
only possibility i found was nowhere the flower is sessile….
in m. densiflora …
but have not found any open access scientific paper that describes its fruit. The fruits in this case as shown seem to be sessile, or almost so.
FEEDBACK FROM THE MAKER OF THESE TWO PICTURES WILL BE APPRECIATED AS WILL SOME MORE PICTURES.


This appears close to images and details at Discospermum sphaerocarpum Dalzell ex Hook.f.
