This wild herb found in a village wasteplace. I didn’t have any scale, please guess approximate size by comparing the common grass yellow butterfly.
As per KEY and distribution of ‘Bengal Plants’ this should be Leucas mollissima Wall. Yes it is Leucas mollissima Wall.

I have also posted the same plant for ID. Hope it is resolved. I hesitate to say that I think the species in this thread looks like- efi thread efi page on Leucas decemdentata (syn. Leucas mollissima Wall. ex Benth.); I do not find difference with this species and the one linked at efi thread 1st and 4th pics are different from 2nd and 3rd, may be same species, but certainly recorded at different time. As per distribution given in the monograph this is, to my understanding Leucas decemdentata (Willd.) R. Br. ex Sm. var. decemdentata.

This Leucas was photographed in Almora district at an elevation of 800m. It is Leucas biflora A reply in another thread: My record of L. biflora is different to this one. Unlike … thread here number of flowers are less and calyx teeth triangular. …, please ensure it has to be procumbent to be Leucas biflora (Vahl) R. Br. Moreover, branches should be many, pubescent with deflexed hairs; leaves should be pubescent on both sides, I am not sure of how the hairs in the photographs can be defined. The problem is hairs in L. decemdentata also varies from glabrate to villous to strigose.
Another problem area is calyx mouth is dialated, distinctly ribbed, rib excurrent to calyx teeth (a feature of L. montana not to be found in your area. calyx teeth linear-subulate). But can those teeth be called triangular-subulate (a feature of biflora, decemdentata, lanata)?
Please check my record of biflora at efi thread and … at efi thread 2 … decide yourself. Thank you … for analyzing my species in detail. I really appreciate your efforts in concluding the IDs of plants posted in eFI.
I too agree that my plant is not L.biflora which is not known in Uttarakhand also. Leucas is represented by following species in Uttarakhand- L.aspera (no resemblance)-
L.biflora (Little resemblance)- http://apps.kew.org/herbcat/getImage.do?imageBarcode=K001115027 L.cephalotes (no resemblance)- http://apps.kew.org/herbcat/getImage.do?imageBarcode=K001114974

June15sk12/12 : Leucas spp. in West Bengal : 4 posts by 1 author It is difficult to me to differentiate the 3 spp. having truncate calyx mouth – (1) L. decemdentata var. decemdentata (2) L. lanata var. lanata (3) L. montana. For, descriptions of the above three spp. appear similar to me. Differentiations though starts with stem indumentum are not enough to enable a non-botanist to have a good grip over the above three.
In spite of the above I think the attached plate, prepared from my one earlier thread is of Leucas decemdentata var. decemdentata for its –
Thank you
Attachments (1) I would like to conclude this Leucas episode with an information, from the monograph, that I missed to note earlier. This is related to identification of L. decemdentata, L. lanata and L. montana. There are info on flowering season, ecology etc which may further help identification but I would skip this.
As per the monograph –
While the first one above is perennial the 2nd one is annual.
So, please check your species where I did comment and correct the ID accordingly.
Leucas lanata Benth. (accepted name) : 7 posts by 3 authors.

I checked but elevation is not matching.
I hope you know very well about species grows elevations, every time not important elevation If we sp. identified exactly. ex. Cleome viscosa grows at 5 m elevation and 1350 elevation too.
Yes I understand . Global warming. But to just make sure.

Yes, to me also appears close to Leucas decemdentata (Willd.) Sm. as per comparative images at Leucas . Location: RAJOURI JANDK Habit: Herb- I’d requested 3: 1 high res. image.
Segregating posts with the same subject. Please check Leucas ! Leucas chinensis I hope I find it more closer to Leucas biflora (Vahl) R.Br. ex Sm. as per comparative images at Leucas
Can you post more images for proper id? 2 high res. images. This looks like L. decemdentata.

Location: Pokhara , Nepal
Altitude: 2600 ft.
Date: 27 July l 2015 Looks different from images at Leucas lanata Pl. check with the images at Leucas aspera (Willd.) Link I do not think that the plant (in the photograph) has softly wooly desnely haired. In L.lanata the leaves are densely covered with woolly hairs so that they appear silvery and leaves are short-stalked I still guess it is matching more to L. lanata as leaf pattern does not look like matching with L. aspera. L. decemdentata
Lamiaceae (incl. Verbenaceae) Fortnight: TC03 – Leucas for id. : 13 posts by 5 authors. Attachments (1)
Goa, Kolem, roadsides, somewhat straggling. Leucas species in eFloraofindia (with details/ keys from published papers/ regional floras/ FRLHT/ FOI/ Biotik/ efloras/ books etc., where ever available) looks like Leucas chinensis This is Leucas biflora i thoght
bcoz here stem looks quadrangular, leaves petiolate lanceolate I remember you identified my thread of Leucas biflora.
Usually in L. biflora (Vahl) Sm. number of flowers per whorl is 1 to 4 (sometimes upto 6) and flowers are pedicellate. Here the number of flowers seems to be more than biflora and those flowers look sessile. Moreover flowers are densely arranged.
So, I request you to reconsider the ID of this species. It is interesting to note that account of Leucas chinensis (Retz.) R. Br. in FoC is a bit different than Indin sites like http://keralaplants.in/keralaplantsdetails. Also one has to take note of calyx mouth http://apps.kew.org/herbcat/getImage.do?imageBarcode=K000929492. find out difference between two here please
i have seen L biflora not L chinensis so you only decide I am happy that … is back armed with his websites and solutions with nomenclatural and identification problems. I am sure now I will get the correct identity. I hesitate to say that this plate or photograph is not enough to identify the plant at species level. I am sorry Smita Ji I couldn’t find differences of L. biflora and L. chinensis in the FoC and pdf links you have provided. I already have the pdf paper since 2012 – efi thread. And when I write “account of Leucas chinensis (Retz.) R. Br. in FoC is a bit different than Indian sites” it means I have read FoC description.
While some authors think that L. biflora doesn’t form flowering whorl, and quite naturally when we see that usually there are only 1 or 2 flowers per verticillaster, other authors use the term “whorl” when they note presence of 4 or more flowers.
Let’s see what are Smita Ji’s points –
…, I also never seen L. chinensis but then I didn’t see many many species…. yet I try.
Attachments (1) That’s what exactly i said on the basis of two links i have given i thought it is L biflora
but as i said i have never seen L chinensis it is up to you to decide
as you have come to conclusion it is L chinensis
i mean i stand corrected Leucas chinensis The problem is TPL thinks L. chinensis, L. chinensis var. lanata, L. mollisima var. chinensis ….all synonymous (with one or more star rating). But FoC thinks otherwise –
Unfortunately FoC doesn’t feature L. biflora.
It is interesting to note IPNI detail on Leucas chinensis R. Br. The protologue can be found (attached herewith also) at http://biodiversitylibrary.org/page/.. More, interesting is account of Leucas by Brown in that protologue. Here is an illustration of decemdentata (it’s a different taxon in TPL) – http://plantillustrations.org/illustration.
IPNI informs”basionym not stated” for Leucas biflora (Vahl) Sm. Protologue of Leucas procumbens Thwaites can be found at http://www.biodiversitylibrary.org/page/ This protologue refers Wight’s illustration. Attached herewith Wight’s account of the species.
I think I have provided ample links of websites for nomenclature and identification problems.
Unless we have the “work(s)” mentioned in another thread, along with more elaborate photographs of this species nothing is confirmed.
Attachments (3) How about Leucas chinensis? Pl check this link- India Biodiversity portal: http://indiabiodiversity.org/species/show/251140 I would like to put a question mark on its identity as Leucas chinensis (Retz.) R. Br. The species usually has 3-8 flowers per whorl; 1-1.5 cm long calyx tube, abruptly dilated mouth, broadly triangular spreading teeth — all these characters are not clear in the attached photographs. This can’t be L. biflora as well.
L. montana (Roth.) Spreng can be straggler, but have truncate or rounded leaf base. L. lanata var. lanata, an erect perennial, has rounded or slightly narrowed leaf base. L. decemdentata var. decemdentata, an annual can have cuneate leaf base (L. chinensis also).
So, id of this one remains unresolved.

What about the next page? Next page is descriptions of L.ciliata, L.indica & L.mollissima Out of the distributed species as per your book, there is some possibility of this being Leucas decemdentata (syn. Leucas mollissima Wall. ex Benth.) as per POWO.
… may kindly have a look pl. It may be L. decemdentata. Material should be checked to confirm it.

Leucas aspera (Willd.) Link (accepted name) again ?? Does not seem to match with images at Leucas aspera
Appears close to images images at Leucas eriostoma Hook.f. , but not found in Nepal.
This is the closest I could find as per comparative images in efi at Leucas It is not Leucas aspera, but very close to leucas eriostoma, there is some possibility of it may come as an escape I am unable to decide. Any how please check these links for final decision: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3249907/
http://threatenedtaxa.org/index.php/JoTT/article/view/977/1750 To me it seems to be Leucas lanata.
FLOWERS OF THE HIMALAYA by Oleg Polunin and Adam Stainton refers (page 328, se no- 1131 Plate no 104). Thanks, … You are right.
… images matches with images of the same species in the following postings:

However, flowering period and the altitude differs according to FoN and book published in Nepal but matching altitude with FOI but flowering period differing slightly.
http://www.efloras.org/florataxon.aspx?flora_id=110&taxon_id=242423824 Thanks for the finalisation of the ID. It should be correct. Now only I noticed your mail. I could not operate my rediffmail so long and now rediff gave me a chance to operate after paying. So I opened it and found your mail. It is about the Leucas you had collected from Nepal, Gattiban 5 Oct 2017. It is interesting I will once again check it but I found something new. If you have specimen or about to collect anything please send it tome. Any opinion ? Could it be Leucas decemdentata (Willd.) Sm., since Leucas montana (Roth) Spreng. most probably it is decemdentata which has some varieties also. . References: |
