2015april_sk02/02 : Phaulopsis dorsiflora (Retz.) Santapau? : 5 posts by 3 authors. Attachments (9)
I have two earlier threads of the same plant. First identified by … – efi thread 1 and again second time myself – efi thread 2.

This is a two to three ft herb, hard to give you actual size, since it’s a weed those are cleared regularly. You can view stat in my earlier uploads in the 2nd thread above. At least one book informs the species is present in lower Ganga delta.

I too would like to know the difference between Phaulopsis imbricata and Phaulopsis dorsiflora. Apparently in a monograph by Mariette Manktelow (1996), it is listed that Phaulopsis imbricata does not occur in India and Phaulopsis dorsiflora is the one we find growing here.

This was told to me by …

Unfortunately I do not have any actual facts to back this up as the monograph does not provide a preview of any part and the book is unavailable for purchase. May be someone from a taxonomic lab can help us with this.

Thank you very much … This information is enough for me to go with P. dorsiflora (Retz.) Santapau.

Thanks, … I agree with you, pl. see Phaulopsis

This is further confirmed in another thread. Thanks to Dr. Mariette Manktelow

Well, … played the most important role followed by … And finally you have the important mail from the author.
