I just came across the description in Herbaceous Flora of Dehradun by C R Babu, adjacent to our Chakrata. He reports Indigofera prostrata from the area, a species that was treated under I. trifoliata in FBI and few other Floras, but as distinct species by Gamble, Babu and now The Plant list. According to Babu the two are differentiated as under:
*Indigofera trifoliata: *perennial, stout stems, leaflets shallowly notched, stout; pod 8-10 mm long, 2 mm broad, 4-6 seeded; sutures winged, seeds as long as broad. *Indigofera prostrata:* annual, slender stems, leaflets obtuse mucronate, slender; pod 13-15 mm long, 1 mm broad, 8-9 seeded, faintly winged; seeds longer than broad. In above photographs leaves appear mucronate, but other things don't match I. prostrata they rather approach I. trifoliata. Your comments please. -- Dr. Gurcharan Singh Retired Associate Professor SGTB Khalsa College, University of Delhi, Delhi-110007 Res: 932 Anand Kunj, Vikas Puri, New Delhi-110018.
