Submission of Cynodon barberi - YS Apr/2020-04

[Yogesh Sharma]

Respected members,

This grass is a species of genus Cynodon Rich. looking different from Cynodon dactylon (L.) Pers. in its overall size.

According to a book, named 'Grasses of Punjab & Chandigarh' by P.K. Khosla, this sp. perfectly matches with Cynodon barberi Rang. & Tadul. So, firstly I did identify it as C. barberi. But than I checked Grassbase and POWO. Grassbase did not show any description for C. barberi but POWO had a description, being showed according to Grassbase, in which the size of spikes in inflorescence was not matching. So experts please help to resolve this confusion.

I'm quite convinced by the key and description given in above stated book but confusion arose because of the description on POWO, which could be a mistake, I think !

Key:-

1a. Lemmas more or less equal to upper glumes, hairs on lemmas clavellate.................C. barberi

1b. Lemmas longer than upper glumes, hairs on lemmas not-clavellate........................C. dactylon

Date of Photo - 10th August, 2019

Place - Rewari, Haryana.

This is also Cynodon dactylon. The length of upper glume in (5) is definitely shorter than lemma. In (6), it seems to be longer, may be due to the angle of photography. Even otherwise, there are a lot of varieties of Cynodon dactylon, both indegenous and exotic developed as fodder and lawn grass. Hence there is lot of variability in Cynodon dactylon.

Cynodon barberi is a different species with different habit altogether. It has no stolons and hence do not spread to large areas like Cynodon dactylon. The leaves of C.barberi are shorter than that of C.dactylon. The leaves are not linear, but are lanceolate in C.barberi. I am attaching the Kew herbarium sheet of C.barberi.
