Would you please share some more information on this interesting
Commelinaceae plant? I am interested in knowing whether you could see
only this individual or more of the same.

If there were more individuals around, was there any difference in the
inflorescence?

Was the stem (at least the base) trailing on the ground?



Thanks and Regards,
Giby

3-4 Plant was about a feet height amid strobilanthus ; all were at same height; besides a stream; i too searched in commelinanceae, but didn't succeed.I remember them erect, straight from soil, not trailing.

Thanks for the additional information. Let me try for this. I too have
seen this plant at higher reaches of Brahmagiri hills that was also
along the streams. But there were no flowers that time.

Not much knowledged about Karnataka plants...but this looks like
Pollia sp. to me.

Mayur Ji may confirm it.

Ritesh.

Please check Pollia secundiflora (Syn. Pollia secundiflora var.
indica and Pollia sorzogonensis var. indica) of Commelinaceae family

I am little doubtful about the inflorescence

Please check whether the fruits are indehiscent and blue in color at
maturity.

If not, we may need to reconsider the id.

Regards,
Giby

Dictyospermum ovalifolium has a synonym, Aneilema ovalifolium and is endemic to the Western Ghats.

Shivaprakashji, 

Few clarifications (please consider these clarifications for better understanding of the species). Whether the fruits are dehiscent or indehiscent and blue at maturity?

whether the leaves (especially lower leaves) petioled or not? and  the number of perfect stamens.  Please check and share these information, if possible.   Regards, Giby

Hello everyone

First up all I wish to clear genus Aneilema is truly African genus and not a single species of Aneilema is found in India.

However, all the earlier Indian Aneilema species are synonymous under few genera like Murdannia, Dictyospermum, Pollia and Rhopalephora. 

All these above mentioned genera are differentiate on the basis of capsule and stamen character.

Stamens 6..........Tradescantieae (Cyanotis, Amischtolype, Callisia, Tradescantia, Belosynapsis, etc)

Stamens 2-3 .................................... (Commelina, Murdannia, Pollia, Rhopalephora, Dictyospermum)

Stamens antesepalous..............................Murdannia

Stamens all anterior............................

Fruits sticky with hook-hairs.......................Rhopalephora

Fruit indehiscent, berry like.........................Pollia

Fruit dehiscent ........................................Dictyospermum

Dictyospermum Wight

Thyrses mostly 5- 16 cm long .........................Dictyospermum montanum Wight

Thyrses mostly 4- 6 cm long............................Dictyopsermum ovalifolium Wight

And I am sure (its my personal opinion) the above posted specimen is Dictyopsermum ovalifolium Wight

Thank you for giving me opportunity to explaining the things again.
