Mimosa himalayana Gamble (syn. Mimosa rubricaulis sensu auct.; Mimosa rubricaulis subsp. himalayana (Gamble) H.Ohashi);
.
A large deciduous shrub with ribbed densely hairy branches with straight or hooked up to 4 mm long prickles; leaf bippinate with up to 25 cm long rachis; pinnae 5-12 pairs, leaflets (pinnules) 6-15 pairs, 3-8 mm long; flowers pink fading to white in 12-15 mm across heads on up to 6 cm long peduncle, forming panicle; pod up to 10 cm long, 4-10 jointed, glabrous, with few prickles on sutures.
.
May be confused but easily differentiated from M. hamata, latter has shorter rachis (up to 5 cm long), few pairs of pinnae (3-6 pairs), fewer leaflets (6-10 pairs), smaller in size (2-3 mm long) in; shorter peduncle (2-3.5 cm) and shorter falcate pod (6-7 cm), velvety and densely prickly on sutures.

Photographed from Near Nagrota (10 km from Jammu) in J & K in August Any member having access to the following publication may help in knowing differences from typical M. rubicaulis I too have photographed these a little after leaving Jammu. Yes … Common in subtropical Himalayas Common in Haryana also along bank of canals etc Google search gave me a small peep into Jastor Gamble original paper: Kindly find attached The Indian species of Mimosa by J S Gamble.
  M. rubicaulis from IOCL Panipat Canal: Mimosa rubicaulis small tree found along canal banks, photo 24-10-2006 Yes … We had it once in our Botanical Garden, but no longer. Thsi also found in Bengal i too have seen it. In Pune (Mah) I have seen Mimosa hamata which is similar to this plant. 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 More Pics from Village Khukhrana Panipat, Shot yesterday According to the key and information from Gamble’s paper this is M. himalayana.
Mimosa rubicaulis does not grow in North India I have also collected the same species from Mahendragiri hills and Ranpur in high altitudes.

Mimosa rubicaulis does not grow in North India Thanks for Correction Sir. I will change my labels accordingly
Superb catch … Thanks for sharing. I have also collected the same species from Mahendragiri hills and Ranpur in high altitudes.

Sharing some pictures I guess is Mimosa himalayana Gamble (accepted name) shot at Kurintar, Nepal on 9 August 2014 at 1000 ft.

Mimosa diplotricha from Hooghly: 11 posts by 3 authors. Attachments (8) I asked myself –
When i saw this plant i was sure that it was Mimosa pudica. But when i touched it, it didn’t response! I touched again, this time harder, but it didn’t response. I hit it with my plastic scale on its highly prickled stem and it appeared to me that it did response! Or was it an illusion, i asked myself.
As i was going through my old records of Mimosa pudica i realized that it was not the same plant. Net search gave me Mimosa himalayana. I was about to id this plant with the same. But searched further and found Mimosa diplotricha at FoC – http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=242332757.
I think this is Mimosa diplotricha var. diplotricha as in FoC – http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=250019707.
Species : Mimosa diplotricha var. diplotricha
Habit & Habitat : shrub, about 6.5 feet, beside railway track
Date : 01-Sept.-2012, 4.30 P.M.
Place : Baruipara (Hooghly)
ID help :
It would have to much easier for us if you had given the characters on the basis of which you rejected M. himalayana and chose M. diplotricha.
On the basis of preliminary comparison your plant does not appear M. diplotricha, in which there are generally more than 20 pairs of leaflets and latter are densely silky.
One important thing to note is that your first plant is much different from your other photographs, in both number of pinnae, number of leaflets and flower colour. I fear they may be two different species. The first has nearly 10 pairs of pinnae and 11-12 pairs of leaflets. with much longer leaves. The other seems to have 5-7 pairs of pinnae and 10-12 pairs of leaflets.
Both M. rubicaulis and M. himalayana (often treated under one species) are recognised as distinct species by the Plant List and Monograph on Indian Mimosa by Gamble. Former has usually 4-6 pairs of pinnae and 10-15 pairs of leaflets. Latter has 8-12 pairs of pinnae and 16-20 pairs of leaflets. Your plant (except first) seem to be fitting M. rubicailis.
I am attaching the paper for your reference. Thank you very much for elaborating on Mimosa sp.
I am not sure if the attached pictures were of the same plant.
There were a small community at that place, spreading along railway tracks and 100 meters away from the railway tracks, inside a private unused land, inaccessible to me.
I took more than 50 pictures from 3 plants lined in a series, having a space of about 20 to 30 feet between each other, along the rail tracks. Of these 3 plants, the first two were beyond my reach and i could take only distant shots with my 5x (200mm) zoom. I could access a branch of the 3rd plant and took closer photographs.
I regret that i didn’t record any leaf, leaflet, petiole, peduncle measurements and could not find any fruit.
It was a cloudy day with high wind and the sun played hide & seek. Colour variation in attached photographs resulted from variable intensity of sunlight and controlled aperture setting by myself.
The description of Mimosa diplotricha available in the sites i cited in my post is confusing. An example : 11 to 30 pairs of leaflets on each of 3 to 10 pairs of pinnae. However, one site states leaflets sessile, opposite, lanceolate, acute – http://www.hear.org/pier/species/mimosa_diplotricha.htm, whereas leaflets in my post, i think, not acute.
I very much wanted to ID this plant as M. himalayana, but nowhere i could found that M. himalayana is moderately sensitive, even in any thread in the group posts i browsed :- efi thread one, two, three, four and five
One thread in group informs M. himalayana is a small tree, my plant is not.
Attaching larger pictures of the same plant or plants.
If Mimosa himalayana is a sensitive plant then my species is Mimosa himalayana. Our first work in CAL next is checking mimosa in Herabriumnext Gdn office in top floor and in hall two where type section etc is kept. this is another example for independent KYDIANA FOR SUCH items on geogrphical elementS of taxonomy., Unless I see the whole world in Herabrium I dont publish any speciEs as species is not based on just one specimen SO I DID NOT PUBLISH ANY SPECIES AT ALL -when a plant by railwaytrack can be from source of Sunflower or tobcco plantation in Mexico which we are growing here.. Just inone day a seed can be taken to Sandieg o! at extreme west from Hoogly in East . Good observations using all senses I am sorry that data deficiency may plague this species to identify it to species level. I have visited and recorded fresh pictures of this plant today, at Baruipara (Hooghly). I am attaching those images in two mails, for their bigger sizes, so as to study various features of this species.
I repeat that this plant is sensitive as can be seen in the first two pictures, taken within a gap of less than 1 minute.
