Thanks, Paradesi ji, for the id.
Flora of China gives very good keys to find out the species, even without flowering:
2 (1) | Leaves 20-40-foliolate; leaf rachis 4-10 cm, internodes often less than 3 cm, node often gibbous; corolla standard 1.1-1.3 cm. | | 3 S. sesban |
+ | Leaves 40-80-foliolate; leaf rachis 13-30 cm, internodes often more than 3 cm, node not gibbous; corolla standard 0.9-1 cm | | (3) |
| | | |
3 (2) | Branchlets, leaf rachises, and flower rachises without prickles; leaflet blades adaxially ± villous when young, glabrescent; standard wider than long. | | 1 S. cannabina |
+ | Branchlets, leaf rachises, and flower rachises with ± projected prickles; leaflet blades usually glabrous; standard longer than wide. | | 2 S. bispinosa |
Hi, Alka ji,
You may check these for further confirmation.
At initial glance I agree with Paradesi ji.
