Begonia crenata

Thanks a lot. 

[Prof. Dr. Santhosh Kumar Rajamani]

Could you help with the taxonomic key or any key identification point to differentiate Begonia picta and Begonia crenata? 

They both look the same to me...

Thank you Gargji and Saroj kumarji

[Prof. Dr. Santhosh Kumar Rajamani]

I have also uploaded a small video on YouTube showing the habit of this beautiful species...

Thank you Gargji,

From my understanding of the Keys at the above site,

To differentiate the two specis is number of chambers seen in the ovary(seen via a cross cut through the flower), 2 is Begonia crenata, stems holding the flowers is devioid of hairs(glabrous).

Crenata is common in Western Maharashtra and Karnataka.

3 chambers is Begonia picta, 2 placenta in 1 chamber each(6).

Also picta is a Himalayan species, found in altitude of 800meters and above.

Flowering season for both is same Aug to Sep/October.
