Hooked Mimosa • Hindi: Mundi, बंदर की राखी Bander-ki-Rakhi • Marathi: गुलाबी बबूल Gulabi babul • Telugu: Undrakampa • Kannada: Sagari mullu;
India (N): Andhra Pradesh; Delhi; Gujarat; Haryana; Karnataka; Kerala; Madhaya Pradesh; Maharashtra; Pondicherry; Punjab ; Rajasthan; Tamil Nadu; Uttar Pradesh; Pakistan (N) as per ILDIS;
Mimosa pudica is a small low-spreading shrub scarcely more than 50 cm tall, M. hamata is robust shrub up to 2 m tall 
M. pudica has only 1-2 pairs of pinnae crowded at tip of rachis, M. hamata has 3-6 pairs of widely spread pinnae
M. pudica has 12-20 pairs of leaflets, whereas M. hamata has 6-10 pairs of leaflets
Fruit in M. pudica is less than 2 cm long, glabrous with spinous sutures, it is 5-8 cm long in M. hamata with velvety surface and prickly sutures.
M. hamata, is however much closer to M. himalayana in which pinnae are 5-12 pairs, and pod glabrous 
 
I could locate the following differences between the two species
M. rubicaulis                                              M. hamata
Pinnae usually more than 5 pairs                Pinnae usually not more than 5 pairs
Midrib lateral                                              Midrib near middle of leaflet
Flowers rose coloured fading white             Flowers red
Pod sutures glabrous                                  Pod sutures armed with hooked prickles

does it have thorns?
can it be used a a hedge?
do birds like the seeds, have you noticed?
Nice pisture, I liked the shrub esp…

Can’t comment about birds but butterflies Yes. Highly prickly plant including the pods as depicted in pictures.

what is the difference between mimosa hamata and pudica


Mimosa pudica is a small low-spreading shrub scarcely more than 50 cm tall, M. hamata is robust shrub up to 2 m tall 
M. pudica has only 1-2 pairs of pinnae crowded at tip of rachis, M. hamata has 3-6 pairs of widely spread pinnae
M. pudica has 12-20 pairs of leaflets, whereas M. hamata has 6-10 pairs of leaflets
Fruit in M. pudica is less than 2 cm long, glabrous with spinous sutures, it is 5-8 cm long in M. hamata with velvety surface and prickly sutures.
M. hamata, is however much closer to M. himalayana in which pinnae are 5-12 pairs, and pod glabrous

This was growing amongst bamboos. Shrubby and stems were prickly


Mimosa hamata

Mimosaceae


How does one differentiate it from Acacia torta/ Mimosa intsi {pink flowered variety}?

Possibility of Mimosa rubicaulis


Or Mimosa hamata. Common in Maharashtra.


Yes …, you are right 
Mimosa hamata: Pinnae 3-6 pairs; rachis 2-6 cm long
Mimosa rubicaulis var. himalayana: Pinnae 5-12 pairs; rachis 10-23 cm long
We don’t find more than 6 pinnae in any leaf.


But I think there are more Pinnae here and the flower much paler as against darker.
I think this goes more in favour of M.rubicaulis
Do you know of any other character? I think we had discussed earlier too.


I think … got it correct.


Pinnae are the divisions of first order which I count 5 pairs in most leaves; leaflets (pinnules) i can count 9-10 pairs in each pinna
Mimosa hamata has 3-6 pairs of pinnae and 6-10 pairs of leaflets
Mimosa rubicaulis ssp. himalayana has 5-12 pairs of pinnae and 6-15 pairs of leaflets
I think there should be no doubt now. Here are links to compare
M. hamata leaves are 2-5 cm long and M. rubicaulis leaves are 15 cm long. Number of pinnae may overlap but pods in former are pubescent with prickly sutures and for latter they are glabrous and not prickly.
From leaves this seems M. hamata.


Thanks … for initiating this interesting insight into Indian species of Mimosa
Gambles original paper may help in separating Indian species
only 3 species (fourth not Indian) in FBI, 7 in Gamble
Here is key based on that paper and some additional information
The key has been uploaded on our website
1a. Rachis shorter than 5 cm………………………………………………………………….(2)
1b. Rachis longer than 5 cm……………………………………………………………………(3)
2a. Pinnae 1-2 pairs, clustered (digitate) at tip of rachis; leaflets 12-20 pairs;
pod glabrous, 3-5 seeded…………………………………………………………………….Mimosa pudica
2b. Pinnae 3-5 pairs, spaced on rachis; leaflets 6-10 pairs; pod velvety, 5-8 cm
long, 5-8 seeded; sutures prickly……………………………………………………………Mimosa hamata
3a. Sutures of pod with strong recurved prickles; leaflets semicordate at base………..(4)
3b. Sutures of pod with few small or no prickles; leaflets semireactangular at base….(5)
4a. Pinnae 3-5 pairs about 2 cm apart; leaflets 4-5 pairs, distant; pods usually
acute at tip, 15 mm broad………………………………………………………….. … … … Mimosa polyancistra.
4b. Pinnae 5-7 pairs about 12 mm apart; leaflets 7-8 pairs, approximate;
pods obtuse at tip, 10-12 mm broad … ……………………………………………………..Mimisa prainiana.
5a. Pinnae 4-6 pairs; leaflets 10-15 pairs, 10-18 mm long; pod 15-18 mm broad……….Mimosa rubicaulis
5b. Pinnae 6 or more pairs; leaflets 12 or more pairs, less than 12 mm long; pod
less than 12 mm broad…………………………………………………………………………..(6)
6a. Pinnae 6-8 pairs; leaflets 12-18 pairs, 8-10 mm long; pod much curved,
8-10 mm broad……………………………………………………………………………………..Mimosa barberi
6b. Pinnae 8-12 pairs, leaflets 16-20 pairs, 5-8 mm long; pods little curved,
10-12 mm broad………………………………………………………………………………….Mimosa himalayana.

Looks matching.

theoretically, it would be mimosa hamata, if its from the thar desert area.
in kuchchh its called zinziniyu (in gujarat called arati and Kasi, Kai baval in Saurashtra)
that implies it grows in desert and other soils.
i guess it perhaps refers to folklore that the seeds may perhaps rattle inside their spiky capsule???
would like some feedback on that and some pictures of the seedpods.
diagnostic feature apparently is presence of hooked spines and prickly sutures of the seedpods.
can we ask to see those seed pods please????
second picture has problems- the closer to the lens objects are not in focus, the distant one are a bit better but by not much, better luck next time


i found some very nice set of pictures showing all the diagnistic features at the butterflies of india site

apparently this plant is a provider of nectar for these insects in Kerala no less!!!
something to remember to include in all our photos for  showing the diagnostic criteria.of any plant
