Breynia compressa ( Phyllanthaceae) from Nepal

[Tapas Chakrabarty]

I found this excellent image uploaded by Saroj ji in Flicker.

Here the male calyx segments are 6-lobed and each lobe is again bilobulate. This character distinguishes this species from Breynia quadrangularis which is always having six triangular -lanceolate lobes of male calyx.

Airy Shaw (1972) and Van Welzen (2003) considered and treated both of these species as conspecific but B. quadrangularis is in my opinion is distinct on this character as the characters of the male calyx are of great diagnostic impotence in Breynia. 

Regards.

Dear Tapas Da,

Though the databases like POWO, CoL, GBIF and WP are showing its (now Breynia rigida (Thwaites) Chakrab. & N.P.Balakr.)

distribution in Nepal there is no record in the Nepal Herbarium and no mention in the latest book published in 2022.

Could you please send me its description, images and article / journal if you have them.

In the mean time, while going through the images again ( though the images are not clear), the 6 petals which are bifurcated

looks different. Could it be Breynia amoebiflora (Airy Shaw) Welzen & Pruesapan ( no distribution in Nepal) ?

Please have a look.

Thank you

Dear Saroj ji,

Here is the details of Breynia rigida from the book Indo-Burmese Phyllanthaceae. This species occurs in Nepal. The second image above (as attached here aleo) is of B. rigida.

Hope this helps.

Kind regards,

Tapas

Thank you Tapas da,

I would be happy if I could find the plant and herbarium images so that could be 

added in the Nepal database.
