Leucas stelligera, perhaps.

Leucas eriostoma

efi page on Leucas stelligera & Leucas eriostoma

I can only say that in a similar looking post by Anurag Ji I suggested something, but presently I have developed doubt. I simply do not know.
One thread by ... efi thread have been validated by Dr. Sunoj Ji, please check if that can help.
The calyx tube's teeth look different from what I have clicked when compared to ... photos of Leucas stelligera validated by ...
Can I take it as Leucas eriostoma instead? It looks closer to that species.

There are problems ... one is -
Without BSI KEY I am unable to proceed further.

Thank you sir.
I will be visiting Agumbe this month. I'll return with exact measurements and further details of this plant. It grows roadside in the village there. Maybe the descriptions might help then or we could make our own key between the two species and the varieties then.

Without book like efi thread, better BSI publication, I am afraid I could do anything at all.

Thank you once again sir. I may purchase the book soon. Will let you know.

Will be happy to know ID(s) of all pending Leucas, thank you ...

If you have/going to have the monograph please skip the rest of the mail. ...... else -
I realize simply having a book is not sufficient for me to identify certain difficult species, that too unseen/unknown before.
  • problem areas of Leucas eriostoma
According to the monograph Karnataka has two - L. eriostoma var. eriostoma and L. e. var. lanata.
One KEY says L. eriostoma var. eriostoma should have two whorls at most (there are 3 whorls in 100001.jpg).
But the description says whorls terminal & axillary, illustration shows one branch having three whorls.
Calyx tube ribbed and hispid in the upper part glabrous in lower region (calyx in these pics are throughout hairy).

Another KEY, where flowers are in more than two axillary whorls, informs -
(i) calyx teeth stellately spreading, recurved = L. stelligera
(ii) ....... erect or spreading but not stellately, not recurved = eriostoma var. eriostoma (longer leaves, whorls upto 2.5 cm.) and eriostoma var. lanata (having leaves upto 4 cm long, whorls upto 2cm diam.).
  • problem area of L. stelligera
I am not sure if calyx teeth in your pics can be called stellately spreading (perhaps yes to certain degree) and recurved.

As per the monograph L. eriostoma is not distributed in Maharashtra, as is Leucas lanata !

Why don't you check - https://groups.google.com/d/msg/indiantreepix/m-Pw1IryaG8/MtyaXYOWqz4J?
Probably wont be getting the monograph any time soon sir.
Thank you for the key.
I will keep this in mind when I get the plant. I perhaps should also start writing down the descriptions of the live plant as I see it myself. This would save a lot of time for when we both are pouring over keys and wondering if may this or that feature could be described in this way or the other
So, the ball is again in my court!
Well, Anurag ji, I ordered the book just after sending you reply-mail, in this very thread, on the 1st June, received on 8th (not because of eriostoma but because of aspera)!

The 'foreword' informs the genus is highly polymorphic, individuals of a species also show great range of morphological variations!

It is really impossible for me to arrive any conclusion. Instead -
  • leaf 5-10 x 0.5-4 cm, veins 5-7 pairs, very oblique; flower whorls 1-2.5 cm = eriostoma var. eriostoma
  • leaf 2.5-4 x ?? cm, veins ?????; flower whorls 1-2 cm = eriostoma var. lanata
  • leaf 3-12 x 0.5-2 cm, ???????; flower whorls 1.5-4 cm = stelligera
This much I can do!
Thanks for that sir! Should make it handy for when I check the plant up close. :)

First, this is unknown to me.
Second, whorls and bracts are similar to L. lanceifolia Desf., but flowers seem to be too big. Are those flowers in the first pic coming out/ falling off the calyx tube?
Third, I am not sure if it can be L. eriostoma Hook. f.
So, please ask ... if it can be the third one.
In my view it is Leucas eriostema.
Is it same species as in https://groups.google.com/d/msg/indiantreepix/DmuvpQSahPg/IcxyOIcsiawJ, ...?
Not the same group of individuals, not sure if the same species sir.
Located around 3 km apart.
To me it looked same.
