Hi Dinesh, features of bracts and sepals are vital in ID of Argyreias.
I have guessed from overall appearance but the key features may not
show up in the pictures to convince others. Can you pls add on the
above? Regards, Shrikant

Shrikant ji, ... I thought the cropped versions : P1260734_cropped.jpg & P1260728_cropped.jpg would give clue to sepals and bracts ... do not have more photos and frankly, I get mixed up with sepals and bracts, better to say: no knowledge to elaborate.

My doubt is: this plant looks similar to Argyreia sericea, which relatively has a shorter and broader corolla tube


Few views of what I believe to be Argyreia sericea at

Dinesh ji, yes I guessed this plant to be A. sericea from hairy
leaves, silvery white beneath, bracts silky hairy and with parallel
venation. However the plant on your flickr link seems to be A.
involucrata rather than A. sericea. Do take close ups of bracts and
sepals hence forth. Regards, Shrikant

Shrikant ji ... visiting the link today will also show yesterday's views at Lion's Point, Lonavala.


Thus there are:

1) ... Oct 15, 2010 ... Lion's Point, Lonavala

2) ... Aug 27, 2010 ... Mahabaleshwar

3) ... Sep 26, 2009 ... (Pooja Farms) Kolad

4) ... Sep 21, 2009 ... Veravali Botanical Garden, Mumbai

5) ... Sep 21, 2008 ... Vaghbil, Thane.



One point in your FOS says that Argyreia involucrata has its leaves with rounded base, while almost all of the plants in this links collection seem to have cordate (I could be wrong).


With your response, realizing there could be at least two different plants ... however differentiating them confidently is getting difficult for me !!!

Following plants seem to be one kind ... cluster of bracts / sepals look similar to me
1) ... Oct 15, 2010 ... Lion's Point, Lonavala
3) ... Sep 26, 2009 ... (Pooja Farms) Kolad

The other three may belong to another / more kinds !!


Time permitting, you (and all friends) may visit the link, and ...
Clicking on any thumbnail will lead to the photopage ... clicking on "Actions" and then "View all sizes" will give option to see the photo in various sizes including original.



Regards.
