– I think this is called Erand in hindi castor in english economically and medicinally important plant


– Yes Arand Ka tel used in constipation with milk


In roundworm extraction a medicine is first given to kill them and Castor oil given next morning to expel them. We had good experience of it in chilhood, a common practice in hospitals.


– This is still in practice.

The castor bean plant, an erect, tropical shrub or small tree, grows up to 30 feet tall. As an annual in the cooler zones, it grows up to 15′ tall. It is a very fast growing plant.
The joints of the hollow stem, stalks and leaves are reddish to purple.
The 6 – 11 lobed, palmate leaves with uneven serrated edge, are also red or colored and often have a blue-gray bloom. There is also a green variety.
The flat seeds are in a seedpod that explodes when ripen.
All the top of the stem and stalks are the inflorescence with the male – and female flowers. The female flowers are the fuzzy red structures at the top of the flower spike with the male flowers positioned on the lower half, and have conspicuous yellow anthers
The oblong fruit turns brown when ripe. In each seed pod (a capsule) there are three seeds.
The seeds of castor bean or castor oil plant, are very poisonous to people, animals and insects; just one milligram of ricin (one of the main toxic proteins in the plant) can kill an adult. The castor oil is extracted from the beans, which is used for medicinal purposes. Commercially prepared castor oil contains none of the toxin


Correct.

EUPHORBIACEAE FORTNIGHT:: Ricinus communis from Panipat NS-19 : Attachments (8). 4 posts by 3 authors.
This is also one of the commonest species of the family… this one was shot from Panipat….
I hope there should be no problems in considering this as Ricinus communis
Still I am confused by its great variability at different places, like the foliage colour, fruit size and appendages, the colour of stigma varying from greenish to orange to deep red as well as its size …will be happy to read more…

Last four pics are from Shimla, for comparison…


Very clear photos.

ID OF MYSTERY PLANT IN DRY RIVER BED : 15 posts by 10 authors. 1 image.
Could the learned members of the group help identify this plant growing wild in a dry seasonal rivulet at Siswan dam, situated in the Lower Shiwaliks, 20 km from Chandigarh?
This was photographed in mid-December


looks like wild jatropha 


I think Jatropha gossypifolia, escape from cultivation. A sampling discarded or otherwise must have taken root.


To me it looks like the castor oil plant, Ricinus communis.
http://en.wikipedia.org/wiki/File:Ricinus_communis_%28castor_oil_plant%29_at_Bandlaguda_002.JPG


I think … is right. The red tint confused me 


What an escape of Ricinus.


Ricinus communis only…


yes Ricinus communis  


Thanks to all the learned members for the identification.
Could the members guide me on this mystery:
How would a castor plant possibly take root in such wildnerness? How could it have reached this dry seasonal rivulet?


Ricinus communis.


Ricinus communis is mainly a wild species itself.


Ok, thanks


it is Jatropha gossypifolia of Euphorbiaceae family


Ricinus communis


I also initially got confused because of red colour of leaves, but it is clearly Ricinus. Jatropha gossypiifolia has 3-5 lobes leaves with lobes suddenly narrowed at tip. Besides leaf base is cordate with no trace of peltate condition. In Ricinus communis as seen here leaves are 7-11-lobed, slightly peltate towards base, and lobes are gradually narrowed towards tip.

Was it Sarat Chandra or was it Rabindranath – where did I first read about রেড়ি-র তেল (castor oil)? রেড়ির তেলে বাতি জ্বালিয়ে পড়াশোনা? শ্রীকান্ত? I fail to remember.

Wiki says electricity was first demonstrated in Calcutta in the year 1879, commercial utilization much later – http://en.wikipedia.org/wiki/Electricity_sector_in_India#History.
In all old literature I have, the Bengali Name of Ricinus communis L. is BHERENDA, then where from the name RERI came? Am I wrong thinking that RERI is Ricinus communis?
No –
