Thanks a lot for sharing the plant. Frankly, I have never heard of this plant before. Is it very common there? If it is common then you may send me a harbarum specimen if possible.

Very common and localized sir, indeed I made a best herbarium specimen of this during my Master’s.
Will make herbarium and send you sooner.

if possible 4-5 flowers in vile in 70% alcohol. Is it still flowering these days?

I haven’t been to this field recently and might visit after a week sir.

Now the plant H.vridifolia is in fruiting stage. I got a chance to see this species and try to plant that in my garden. Unfortunately it not survive. September I saw this plant in full bloom.

Dont worry, it may be having its perrenating tuberoids underground.
Wait for next year and dont disturb the soil… let the baby sleep!.
