Rhynchosia for ID:
A fabaceae member, Rhynchosia sp.? collected from Tamil Nadu state in November 2011.
Please help me for the ID.

The first set is of Rhynchosia rothii, I think.

Yes first one is Rhynchosia rothii in my opinion also

Rhynchosia rothii Benth. ex Aitch.
Syn: Rhynchosia sericea Span. Gamble, Fl. Pres. Madras 375(265). 1918. In Gamble it is given that A climbing shrub with soft silky pubescence and long racemes of purple flowers.??
Its flower is not purple ……….

You see the fruit which is like Glycine max L.(soybean) and Cajanus, Atylosia cajanifolia as the wild relatives of PigeonPea. It is an impornt genetic resoursce already mentioned by D.C.S,Raju,et al in3-4 papers including Pigeon-Pea workshopat ICRISATattended by Raju and Thothatri
Sppecies of Rhynchofia should be studied in detail. Roth was at Madras as one of the pioneers.

Rhynchosia viscosa (Roth) DC. as per images herein.

It is Rhynchosia rothii; Rhynchosia viscosa is closely related to R.rothii, pod recurved, long tipped with base of persistant style; leaflets softly pubescent; 

Thanks, … But I find the images matching with images at Rhynchosia viscosa (Roth) DC. & not with those at Rhynchosia rothii Aitch.
Pl. reconsider.

Thanks …

The flowers (Flowers yeloow with red/ maroon streaks) and leaf look like that of Rhynchosia viscosa which is common in Nellore district and in E.ghats; but the fruit is similar to that of Rhynchosia rothii; the viscous hairs are not clear, the tip is different from R.viscosa (R.rothii has twany villous hairs on pod, flowers purple)
