Please validate or correct the id of this cultivated legume, recorded from Chakrata area…!!
Is this Phaseolus vulgaris?


Thanks, … I think you are right. Pl. see Phaseolus vulgaris  


Yes it is


I don’t think it is Phaseolus vulgaris L. It’s possibly a Vigna species. 


First i will tell you why it is not Phaseolus vulgaris L. In Phaseolus corolla morphology is different than Vigna or Dolichos like regular legume species. please check foc illustration (specially no.2 and 5) –http://www.efloras.org/object_page.aspx?object_id=116327&flora_id=2. Corolla in Phaseolus mostly features-
  1. standard suborbicular, quite different to other legume genera
  2. wings equalling or exceeding standard
  3. keel beaked, spiral
  4. in P. v. calyx teeth is much smaller
  5. in P. v. flower is subtended by persistent ovate bracteoles
The correct species images can be seen at efi thread
My guess is that you identified your species based on uploads like – efi thread
Now, I will try to identify your species, featured by regular legume flower, long calyx teeth-
  1. please check http://davesgarden.com/guides/pf/showimage/265239/ (efi also features this species)
  2. for varieties check http://www.tropicalforages.info/key/Forages/Media/Html/Macrotyloma_uniflorum.htm
  3. though your 2nd pic seems to show cylindrical pod but immature pods are flattened (compressed) as can be seen in 5th pic of https://groups.google.com/d/msg/indiantreepix/sF4PXYr2UsU/FYltXojWCwAJ
  4. hint of flattened pod can also be seen in your 1st pic
Your species is Macrotyloma uniflorum (Lam.) Verdc.


well, Sir, here is more authentic image of Phaseolus vulgaris – http://www.kew.org/science-conservation/plants-fungi/phaseolus-vulgaris-common-bean


Phaseolus vulgaris is not one plant type

its a group of large numbers of beans  haricot beans… kidney beans, french beans, navy beans white beans , etc have about 14,000 cultivars …  with flowers in lax, axillary few-flowered (12) racemes, zygomorphic, variegated, white, pink, or purplish, ca 1 cm long (from the same James DUke Book)  when one cooks them they all feel and taste different. and their nutrition values are different and their lectin contents and their toxicites are different.
Yet botanically all are classified as Phaseolus vulgaris L.
and this shows a few of the varieties of Phaseolus vulgaris seeds

SO what Kew is showing is not academically correct to represent the 14,000+ cv s flowers which sho w differences

it may be just as an example

… original picture shows the so called french bean of vegetable garden variety with creamy flowers
if it were Kulath Kalai or horse gram as has been suggested those beans look different and are shorter  and much flatter and wider than shown in Gurcharnji’s pictures and Nidhan’s pictures

that’s just an opinion of a gardener

Its upto qualified Botanists to decide, … is one himself
… do you have follow up on your case
did you allow the plant to maturity and look at the beans as they matured? and seeds??
were they one of the many // regular beans or Kulathi


I think There is no reason to confuse this plant with Macrotyloma uniflorum whose pods and seeds are so different. We have been growing this plant in our house, harvesting its pods and seeds for many years. Here is how Macrotyloma uniflorum looks

Thanks a lot, … But why flowers (including the calyx) look so different from images at Phaseolus vulgaris ?
Is there any mix up of images ?


Phaseolus vulgaris L., Sp. pl. 2:723. 1753

Common names: bean, dwarf bean, field bean, flageolet bean, French bean, garden bean, green bean, haricot bean, kidney bean, navy bean, pop bean, snap bean, string bean, wax bean 
Scandent annual with trifoliate leaves; leaflets thin, ovate to rhombic-ovate; flowers white or purplish on peduncles shorter than leaves, few-flowered; pod up to 20 cm long, slightly flattened, seeds kidney shaped. 
Photographed from Mussoorie Chakrata road near Baratkhai, cultivated.


Taking it as Macrotyloma uniflorum in view of discussions in Fabaceae (Faboideae) Fortnight :: Phaseolus vulgaris for validation :: Chakrata :: NS OCT 98/98

Habit, flowers, fruits are so different in Macrotyloma uniflorum

Thanks a lot, … That may be possible. But what about your flowers ?

Flowers look different in your first photo compared to flowers in other photos.
Is there any mix-up ?


… images look similar to yours (except flowers in your first image) except for the pod, which appears slightly different to me. Also check your leaves in the first image compared to the leaves in … post.


I think its horse gram relatives 

FRUITS  and FLOWERS show similarities
