Since I started photographing local flora for this group I have come across several species which are supposedly not to be found in this region of West Bengal, even though they are listed in ‘Bengal Plants’. Today I have recorded two species one of which I have already posted a little while ago.
This is a wild twiner in village thicket.
Leaves are hairy on both surfaces. I am not sure if those can be called villous or pilose or something else.
For the past two hours I went through Prain, Haines, Hooker and Roxburgh. The closest match I could find is Vigna pilosa Baker. Now, leguminosae is a big family. So, it is before you if there is more common probability.
I think ID is correct as per available literature and links –
A new set recorded today (25.2.15)
yes to your query based on your refs.. except for the kew herbarium (i think their leaves a re a bit broader, may be a case of younger or older leaves)
thanks for showing
But I hope you will by now have surmised that all those old books are just that…old to be used as a springboard.. to id to wonder but the current data will be different as you yourself are proving to us
day in and day out.. things change plants migrate … by water, sea, river, floods waves tsunami, by wind .. during slight breeze even or thunderstorms and hurricanes ..where winds carry enormously weighted objects,
by animals .. on their skin in their gut or humans .. via all of the above clothes and by design by carrying the seeds with premeditated design as in mass migration of dandelion we saw in north America.. or wheat as we know it or ganja that go to Europe- the list must be thousands of name long.. or neem and basmati chawal and turmeric and countless others that were planted to study, steal patent rights or belated knowledge and new found openness as in case of the sajne danta gaach..now that the world has discovered the protein content in the young leaves and activity beneficial to kidneys in the green pods as vegetables… does not matter if prain does not say it occurs in bengal… you showed it does and that’s what matters to me and I am sure BSI in its modern avatar will show it or has shown it and we are not privy to all their literature. I don’t know why they make their literature soooo difficult to get hold of or sooo expensive when BSI is a public venture????
What a write up …, only you can do this!
Yes, …, I too have broader leaves, attached here a few more photographs. The plant bears variously shaped lamina, some are falcate too. KEW herb. no. K000900622 (the one with pods) is from Maynmar and the other one is from India.
I went through all vigna, phaseolus, teramnus and others described in FBI. First, I thought it to be a Teramnus. However, the pod and seed size and colour and hairs, shiny surface of seeds all tally only with the ID I have suggested.
Thanks … for showing additional leaves
yes that sort of helps with kew herbarium but I never had doubts about your ID
I didn’t think that you had doubt, I uploaded only because I had more photos and their value can only be appreciated in this group, nowhere else.
