The calyx (Leucas lavandulifolia) is characteristically very oblique at apex, 8-toothed; teeth irregular/ minute and the posterior teeth is the largest. In L. aspera, the calyx is slightly oblique at apex, 10-toothed; teeth unequal but not as above. Of course there are several other differences such as: hairs on the stems are deflexed in the former and they are spreading in the latter species.

Hooghly Today : Leucas aspera (Willdenow) Link: It took me more than an hour to decide not to use “?” in the title of this post. So, i think this is Leucas aspera (Willdenow) Link, a small herb (less than a foot) beside rail-tracks.


Is it Lepidagathis ?


I am not sure, I thought it could be a Leucas species, since the flowers as well as the plant resembles the illustrations at – http://plantillustrations.org/taxa.php?id_taxon=5081.


I think Leucas aspera.


I think I have more clear pictures of this plant, recorded sometimes later after this first upload. Will search my hard-disk and post in this thread.


Attaching new set of this plant, recorded at the same place and of same population.


Lovely pictures indeed, I hope the id is right..Leucas aspera


Thank you very much Sir, two earlier threads helped me much.


In light of upload by … this could be L. ciliata (longer calyx lobes; hispid).


The problem is that learning from here, in this group, I teach, rather give opinion, to my friends in other groups, my students, (sometimes my colleagues too!). Now, I will have to recall whom did I impart knowledge regarding id of Leucas since 2013. Okay… that’s my job, eFI is not at all responsible for that.
Following are the Indian sites which think what Leucas ciliata can be –

It’s hard to believe that the species in this thread is same. But, you are my teacher here and I am bound to accept your verdict.


We on the basis of photographs can only give our opinion only, and not verdict. We learn from each other.


These photographs of a wild herb were recorded on 06-Oct-2014


Leucas species in eFloraofindia (with details/ keys from published papers/ regional floras/ FRLHT/ FOI/ Biotik/ efloras/ books etc., where ever available)


The leaves are covered with hairs (wooly). Could be L.lanata as seen in this link http://www.botanicayjardines.com/leucas-lanata/.


It is Leucas aspera only,


Thank you very much Sir, many thanks to …


.


 

It is Leucas aspera (Willd.) Linn.; not Leucas aspera (Willd.) Link – http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3249907/


Leucas aspera (Willd.) Link should be correct, the Linnaen name is wrong. Actually Willdenow published around 1800 and the name in parenthesis indicate it is the original author who coined the species name. If I remember correctly, Willd. published it Under Phlomis a genus and Link transferred later to the Leucas genus.
I understand being a non-Botanist you may face some nomenclatural rules, but I request you to see the Taxonomic websites like ipni.org; theplantlist.org.


Thank you very much for the correct accepted name. I understand that the authors made an inadvertent mistake in the paper.

Help ID of following herb found in our Tur crop; photo on 16Aug13


This is also a species of Leucas, possibly also the Common Leucas [L.aspera].


Yes Leucas, probably L. cephalotes…


L. aspera


Yes …; leucas aspera.


… confusing. Why not Leucas lavandulifolia Sm. ?


Thank you … On checking available information (to me) I feel that your id suggestion L.lavandulifolia may be right.


This species looks like Leucas aspera (Willd.) Link to me.


……………………


Of the 10 spp. distributed in West Bengal I attach herewith what I think Leucas aspera (Willd.) Link. The photographs used in the plate is from two earlier threads, recorded at same place at different time (January,’13 & Oct.,’14), of same community, but possibly of two progeny.

Is it Leucas aspera– belonging o the Fam. Labiatae (Lamiaceae)?


The plant in the attached photo is Leucas cephalotes (Roth) Spreng.


A reply from another thread:

“One uploaded by … is clearly not L. cephalotes. It appears L. aspera


Yes it appears to be L. aspera.

By the way, this is something I would like to put in general, it would be nice if we take images with scales. Close-ups of flower, inflorescence, fruit and leaves as much as possible should be captured with an accompanying scale for later analysis.


sorry I can not open the link. So far I remember I posted a plant which I thought belonged to L. aspera (I did not mention cephalotes). Thanks for the mail and glad to hear from you.

Re: Correction in eflora page : 3 posts by 2 authors.
In the above page Telugu name is wrongly written as Thumma (Acacia nilotica / babul). Correct name is Thummi​ (తుమ్మి)

Thanks, … I have made the correction pl.

Thanks very much … for the correct name.

Leucas aspera (Willd.) Link : Attachments (2). 1 post by 1 author.

Leucas aspera (Willd.) Link, Fam: Lamiaceae

aromatic herb,
Denkanikota, Krishnagiri DT, Tamilnadu 850m altitude

Medicinal and used for pooja


This one will fall under the first part of my comment – “To me, except for two or three threads where pictures are not at all clear to identify the species, ……”

It has very probability of being L. aspera (Willd.) Link, but better pictures are needed.

Looks different from other images at Leucas aspera (Willd.) Link

Also looks different from images at Leucas cephalotes (Roth) Spreng.

Leucas aspera

Posting again as images not appearing.
Clicked on Sep 2nd, Neemrana (Rajasthan)

Check with Leucas lavendulifolia


I feel it may be Leucas aspera (Willd.) Link as per comparative images at Leucas
It is definitely not Leucas lavandulifolia as per images and details herein.

Pardon me for my low understanding of botanical terminology. What does it mean when the calyx mouth is oblique? I’m not sure what the term oblique means in this context. Would be great if someone could explain


Thanks, … Pl. see any calyx image at Leucas lavandulifolia and you will understand (i.e. calyx mouth is on an incline).


It is L. aspera

“I think … is right
it looks like Leucas cephalotes from lamiaceae


Could it be a dried up plant of Leucas Indica?
Please check the link http://www.flickr.com/photos/amithes/3386432033/

I think inflorescence and leaf morphology does not match with Leuca indica

Appears to be close to  Leucas aspera  


.

3 images. A wild plant.

Leucas cephalotes,


Thanks, …, for the id.

Yes, appears close to images at  Leucas cephalotes (Roth) Spreng.


Seems L. aspera


Looks like Leucas Aspera, very common in Kerala.
