According to the Plant List, B. nervifolium Thwaites is synonym of B.
sensitivum (L.) DC.

B. reinwardtii (Zucc.) Kl: Leaflets 10-20 pairs, tip rounded,, base equal,
lateral nerves slender, oblique; peduncles slender; capsule almost as long
as calyx.

B. sensitivum: leaflets 6-15 pairs (nearly 12 pairs in var. nervifolium in
FBI), usually apiculate, terminal leaflet with oblique base,  lateral
nerves few slender (strong in var. nervifolium) and wavy, especially in
lower part.

Perhaps Santosh ji can throw better light on this.
