Habitat: Grows on roadside
Flower : Large, Yellow in colour
Habit :Shrub

Request Shrub ID 33 – Bangalore – RA:
Is it some wild plant?

Looks like Cassia tora ?

It doesn’t look like a cassia leaves.
I will post of a picture of the leaves.

Cassia occidentalis?

Please check with Cassia hirsuta. We collected this specimen near Maredumilli MPCA, Andhra Pradesh.

I agree with … id, it does look like Senna hirsuta.

It looks like Senna hirsuta.
I will attach a picture of the leaf later tonight.

Thanks for the nice additions, … They look very much like S. hirsuta.


Cassia for ID : 260112 : Mumbai : AK-2:
Another Cassia species seen at Maharashtra Nature Park,Mumbai on 15th of Nov,2011.
Height of plant about 5-6 feet, yellow flowers and tender pods seen.

May be Senna hirsuta

to me it look like Senna occidentalis

I think S. occidentalis has neither hairy calyx nor hairy pods. Senna hirsuta has both.

Yes i agree, but in the photo here, pod is not mature, have not seen C. hirsuta in MNP till date,, will find out if added to the garden..

It is my pleasure to present a few images of Senna hirsuta (Fabaceae 

Habit: Shrub 

Habitat: Wild, Dry deciduous forest fringe. 

Sighting: Chikmagalur and Tumkur, Karnataka, about 1200 msl and 800 msl respectively 

Date: 06-10-2014, 10-11-2014 and 16-11-2014


Cassia for ID 10122011:
Silky hairy shrub 1-2 m tall. Leaves 20-30 cm, pinnate; leaflets 3 cm, elliptic, acute, silky hairy. Flowers in axillary racemes, 2-3 cm, ovary and pods with long silky hairs.
Found in a nursery in Pune. Pls ID.

It may be Senna hirsuta.

Perhaps number of leaflets, presence and location of gland/s and size of pod should confirm conclusively. Other things especially stamens and ovary do fit Senna hirsuta.

Thanks … and … I had arrived at this ID but plants on efloraofindia labelled under this name do not tally with this, however the link provided does fully agree. Leaflets were 6 pairs but ignored the gland. The pods were terete and densely silky.

Six pairs of leaflets further goes in favour of Senna hirsuta

Date 13 DEC 2017
Place Agara Lake, HSR layout, Bengaluru
Plant looks very attractive due to yellow flowers and hairy ‘tentacles’ around inflorescence. The leaves bigger at the apex than the base.

OK. I will check.

I could identify the plant as Senna hirsuta. The tentacle like structures are hairy immature fruits. It also matches with leaves. Three pairs of leaflets, one at the apex being biggest.
Please confirm my observations. 

Thanks, …,

You are perfectly right. Pl. see images at
Sorry,  I sent you a wrong link earlier. Actually earlier lot of herbarous species in Cassia has been transferred to Senna.


Just to keep you informed about my work, I have incorporated here the slide I have prepared.

FOR ID :: ¿ Senna ? ¿ species ? :: Yercaud :: 25 JAN 18 : 3 posts by 2 authors. 9 images.
Yercaud … (literally, lake forest), Tamil Nadu
… proper Yercaud … Date: January 25, 2018 … Altitude: about 1,623 m (5324 feet) asl
Not sure whether Senna OR some other genus. Most possibly an escape. Found growing in an untended place among waste. Flower – about 15 – 20 mm across. You may click on the photos to reach photopage in flickr to download the larger original version (or please ask me to provide).

Senna hirsuta.


Please help me with any of the valid name(s) among malaiyavarai, malaiyavaram, malaiyavirai in native script listed at ENVIS / FRLHT.
I think malai / malaya / malaiya refer to mountain – though mountain / hill does not fit in context of Senna hirsuta; I could be not aware of some word similar sounding and meaning woolly / hairy.
I found அவரை avarai / ஆவாரம் avaram = field-bean, Dolichos lablab

Here are the Tamil names in their native script:
malaiyavarai: மலையாவாரை (மலை + ஆவாரை),
malaiyavaram: மலையாவாரம் (மலை + ஆவாரம்),
malaiyavirai: மலையாவிரை (மலை + ஆவிரை)
I have split the Tamil words above for better clarity. Dolichos lablab is called “avarai” (அவரை) in Tamil. But the name “āvārai” (ஆவாரை) and “āvāram” (ஆவாரம்) refer to Senna auriculata (here comes the importance of phonetics!).
I think the plant here (Senna hirsuta) is compared with Senna auriculata perhaps due to their morphological similarities, and distinguished from it by the prefix “malai” meaning “of hill” or “wild”. The term “malai” could also refer to the hairy feature of the plant.

Thank you very very much … for the help with names in native script and for the clear and lucid explanations !!!
