Dimorphocalyx glabellus var. lawianus (= D. lawianus).

Flowers & fruits look different from other images at Dimorphocalyx glabellus var. lawianus (Hook.f.) Chakrab. & N.P.Balakr.
May I request you to pl. clarify.

Thank you very much for pointing out.

I have now downloaded all the images (unfortunately of very low resolution). I can think of no genus other than Dimorphocalx for the typical male flowers. The last two images are of somewhat immature fruits and they were most probably found on a separate plant (dioecious genus).  The leaves are of typical D. lawianus (note a gland along the leaf-margin on the sixth image, DSC 0587). However, the most obvious difference which I find is the non-accrescent fruiting sepals which clearly points to a distinct and probably undescribed species. This is indeed very interesting (if I am not mistaken) and I would suggest … to go back to the locality, collect specimens and study in detail. Such non-accrescent fruiting sepals are known in D. muricatus of South East Asia and Malesia which however possesses muriculate capsules.
Recently someone sent me a few images of a supposed Dimorphocalyx from North East India which also had such non-accrescent female sepals but the inflorescence pattern was different from the present images.

The images are of Rinorea bengalensis (Wall.) O. Ktze. (Violaceae)
