Keys in Flora of Pakistan are confusing me:

28 (26)	Flower shorter than the subtending bract	Indigofera atropurpurea
+	Flower longer than the subtending bract	(29)

29 (28)	Calyx teeth deltoid, not exceeding the cup	Indigofera hamiltonii
+	Calyx teeth lanceolate, exceeding the cup	Indigofera himalayensis

Here flower appears to be longer than the subtending bract.

Flora of China gives the following keys:

40 (39)	Leaves 3- or 5(-11)-foliolate, to 2.2 × 1.2 cm; racemes much longer than leaves.		24 I. hamiltonii
+	Leaves (7-)11-19(or 21)-foliolate, to 6.5 × 2.5 cm; racemes equal to slightly longer than leaves.		25 I. atropurpurea

In view, we may take … post as Indigofera atropurpurea

Interestingly, Checklist of Nepal gives Indigofera hamiltonii Graham ex Duthie & Prain as a syn. of Indigofera atropurpurea Buch.-Ham. ex Hornem.

So what do you think …? If that is correct then we need to review earlier posts I guess. I am at Kalimpong for a few weeks as such I shall check once again when I am back.
