efloraofindia:”For Id 08122011MR1’’ “Fabaceae-Caesalpinioidea (Caesalpiniaceae) Week:.?any Senna sp Pune:
Dec 2011 Pune
I do not know if this herb falls under the family of this week but sheer resemblance of leaves and what I presume and understand to be glands at the base of some lower leaflets(I may be completely wrong) I make a kind request to Id this herb.
grown on its own in a pot of Pilea depressa in my garden 2 months back
had only 2 leaves for almost 2 months and suddenly in the last 10 days got some more leaves and I think buds
height 6 cms
stem hairy
leaves 2 pairs of leaflets. one lower pair showing I think a orange gland, leaves hairy
flowers green buds and 1 big yellow bud I think
Leaves 8mm breadth 1.1 cms length
buds about 1 mm
I guess Senna uniflora
But on a more rational analysis it could belong to any of the following
Chamaescrista absus: Annual herb up to 1 m tall; pod 3-6 cm long, 4-8 mm broad, elastically coiling; pedicel with bracteoles; leaflets 1-4 cm long, 1-3 cm broad; stamens usually 5, subequal
Senna bacillaris: Shrub or tree up to 8 m tall; pod 15-27 cm long, 9-15 mm broad, not coiling; pedicel without bracteoles; leaflets 5-16 cm long, 2-7 cm broad; stamens 9-10.
I would tend to go with Chamaecrista absus
Since there was a discussion and possibility of Senna uniflora with 2 pairs of leaflets, possibly following chacters should be checked.
It also has 3-5 cm long pod but obscurely 4-angled, appressed hairy, with 4-10 seeds, but bracteoles are absent and leaves are mostly 4 pairs, ranging from 3-5 pairs. 2-5 cm x 1-1.2 cm with mucro at tip, white hairy on lower side.
I rechecked the plant as suggested by you. I photographed the lower surface of the leaf. Attaching the picture of the same. Also attaching another pic which I took on 1st of dec. What I notice is that the younger leaves do show a mucro at the tip but mature leaves are devoid of it. Also there are maximum 2 pairs of leaflets ranging from (1-2). The lower surface of the leaf appears lighter than the upper surface and I think does not show hair. But I am not sure. You are the best judge.
Also max dimensions of leaves are 1.1cm length by 8mm breadth
