Place: Resort at Ooty (~7250 ft asl), Tamil Nadu.
Time: November 15, 2011 at 5.15pm
Habit: large shrub
Habitat: garden flora.
Plant height: about 2 – 3 m
Flower size: about 25 mm across
Leaflets: sessile, apex pointed, 5 to 7 pairs, mostly 6 … clavate glands between each, and all pairs.
Requesting … to re-look at leaflets.
S. sulfurea at Flora of China, described to have clavate glands between each of lowest 2 pairs of leaflets leaflet apex obtusely rounded or inconspicuously emarginate,
Illustration of S. sulfurea shows petiolulate leaflets.
Yes Senna sulphurea
Am I correct? C. surattensis subsp. glauca is the synonym of Senna sulphurea
Was not comfortable with Senna sulfurea because of the non-conforming aspects that I pointed out with regards to the leaflets.
Leaflets in my posted plant: sessile, apex pointed, 5 to 7 pairs, mostly 6 … clavate glands between each, and all pairs.

Thus after re-searching cultivated species of Cassia and Senna, have come across Senna multiglandulosa (Jacq.) H. S. Irwin & Barneby

My strong feeling, my posted plant must be Senna multiglandulosa (Jacq.) H. S. Irwin & Barneby.
Requesting you to reconsider.
… Cassia surattensis subsp. glauca (Lam.) K.Larsen & S.S.Larsen is a synonym of Senna sulfurea (Collad.) H.S.Irwin & Barneby … The Plants List
I think you are right
Just for record, it must be mentioned that this species Senna multiglandulosa is the accepted name for species which was previously known under the name Cassia tomentosa. In fact there are two plants by that name: Cassia tomentosa L.f. and Cassia tomentosa Arn.
Cassia tomentosa L.f. is now correctly known as Senna multiglandulosa (Jacq.) H. S. Irwin & Barneby: is a a tall shrub up to 4 m tall, branches tomenose, 6-8 pairs, oblong, up to 5 cm long, yellowish tomentose beneath; racemes shorter than leaves; flowers deep yellow; fruit thick flat, up to 12 cm long. This should be your plant.
Cassia tomentosa Arn. is now correctly known as Senna hirsuta (L.) H. S. Irwin & Barneby. It is a perennial herb up to; leaflets usually 3-5 pairs, with a gland at the base of petiole, none on rachis between the leaflets, ovate lanceolate, up to 7 cm long, acute or acuminate, hirsute; racemes short, axillary; flowers yellow; fruit linear, up to 15 cm long, hirsute.
Here is the key I have tried to construct to separate the closely related species:
1a. Gland at base of petiole, none between the leaflets; leaflets 3-5 pairs,
ovate lanceolate, hirsute; pod hirsute. 50-90 seeded…………………Senna hirsuta
1b. Glands between pairs of leaflets, none on petiole; leaflets oblong
2a. Glands sessile, between all pairs of leaflets; leaflets 6-8 pairs,
yellowish tomentose beneath……………………………………………….Senna multiglandulosa
2b. Glands stalked, between lower two lowest pairs of leaflets;
leaflets glabrous or white-farinose beneath………………………………(3)
3a. Leaflets 4-6 pairs; leaf 15-30 cm long, leaflets white-farinose
(glaucous) beneath; pod 12-20 cm long, 20-30 seeded;
stalk of pod 10-20 mm long…………………………………………………Senna sulfurea
3b. Leaflets 6-9 pairs; leaf 10-15 cm long, leaflets not glaucous
beneath; pod 7-10 cm long, 20-25 seeded; stalk of pod
5-7 mm long…………………………………………………………………….Senna surratensis
The key is fantastic help, … for separating the confusingly close species.
Many thanks for re-validating the ID too.

Possibily it is Cassia bi-flora.
Not Cassia biflora atleast
this might be cassia auriculata
This is certainly not C. auriculata.
The plant is turning out to be interesting and elusive with narrow thicker pubescent leaves. Foliar glands should help.
Looks like Cassia bahamensis, based on the leaves (origin South Asia). In the absence of details of flowers ( number of petals,stamens, fertile or infertile etc.) it is difficult to confirm.
As per my opinion..
may be Cassia surattensis Burm.f var glauca (Lam. ) K. & S. OR C.S. var. surattensis..
(Ref: YadavS.R. and M.M. Sardesai 2002. Flora of Kolhapur District. p.170 & 174)
Quite likely Cassia bahamensis ?
Not Cassia sophera for sure.
very difficult, but also can be checked with Cassia surattensis, now may be changed to Senna surattensis
Leaves with 4-6 pairs of leaflets, leaflets farinose beneath and young shoots hairy, pod with more than 20 seeds, longer, stalk of pod 10-20 mm all point to Senna sulphurea (syn: Cassia glauca).
Concluding … posted plant to be Senna multiglandulosa … discussed at efi thread
Cassia/Senna for identification 311012MK01: Please help me to identify this Cassia sp. The shrub grown near a garbage site and it was up to 2-3 metres in height.
Leaf: up to 15cm long; leaflets upto 8 pairs
Flower: 2.5-3 cm
Pods: 20cm long; slightly hairy

Place: Ooty, Nilgiris, TN
I think this is Senna siamea
It comes close to Senna bicapsularis, but more details (on glands, stamens etc) required to confirm.
