Thank you … for the post which is new to me. Fruit looks like Globba at a first glance.
Small tree Id requested : 2 high resolution images.
Herewith I am attaching the photographs of a species for identification
Habitat-Small tree, Flowers- green minute
From Ganjam, Odisha, India
Euphorbiaceae member, some characters matching with Trewia,
I could not find a match as per comparative images at Mallotus
this looks like Croton caudatua.
This appears to be a very interesting plant. The leaves/petioles as well as the capsules of Croton caudatus are said to be densely hairy–hispid unlike the plant in this thread.
I think it is more in line with Alchornea mollis (Benth.) Müll.Arg.
Yes, I fully agree. This is Alchornea mollis. The range of distribution of the species is thus extended southwards to Odisha.
I think you are right. The tuberculate capsules are indicative of Alchornea tiliifolia (Benth.) Müll.Arg.
Welcome. I am aware of all the 3 species of Alchornea in India. The dividing lines between A. mollis and A. tiliifolia are narrow. So, one needs to see the undersurface of the leaves for a conclusive decision. The present images are not showing the lower surface clearly. We are unable to know about the foliar glands and the nature of pubescence. Till then, the identity will remain doubtful.
What do you think based on fruit character?
Well, here the fruits are subglobose and smooth, not tuberculate, unlike Alchornea tiliifolia.
Attaching a cropped version of the second photograph in this thread. After Garg ji’s observation, I zoomed into the image and was able to discern several protuberances on the surface of some of the capsules. Would these qualify as tubercles?
Flora of China says “Capsule subglobose, ca. 10 mm in diam., tomentulose” for Alchornea mollis Bentham ex Müller Argoviensis and
Capsule ellipsoid, 6-8 mm in diam., puberulent, tubercled for Alchornea tiliifolia (Bentham) Müller Argoviensis
I think it is Alchornea tiliifolia (Bentham) Müller Argoviensis only.
Please go ahead with A. tiliifolia.
