.
The calyx here (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.
.
Looking similar to L. aspera in appearance but easily separated by less hairy stem and leaves, leaves remotely crenate, calyx tube faintly ribbed, pubescent, limb distinctly oblique with upper tooth much larger than others which are insignificant. Verticillasters are less dense In L. aspera stem is hispid, leaves crenale, calyx tube glabrous in basal part hispid in upper, limb slightly oblique with distinct sharp teeth, verticillasters very dense almost globose.

Many many thanks for pointing to misidentification. Here are all the views of what are labelled as Leucas aspera at
http://www.flickr.com/… If possible, at your leisure please validate the other sightings.
… want to know if Leucas lavandulaefolia Rees (= Leucas linifolia Spreng.) is synonym of
The book, “Plant Groups” mentions two Leucas, 1) L. aspera Spreng = L. mollisima Wall. and 2) L. linifolia Spreng = L. lavendulaefolia Nees.
Well, i have taken care while typing the above names, but there is no L. aspera Spreng in the net, except some research papers on bio-chemical aspects of Leucas did mention it. Neither could i find L. lavendulaefolia Nees.
I was about to id it L. aspera (Wild.) Link, but … is there – efi thread and here – efi thread!
Species : Leucas lavandulifolia Smith ?
H & H : small herb of about 1 foot beside rail tracks
Date : 3/11/12, 10.00 a.m.
Place : Hooghly
But where are the L. aspera Spreng and L. lavendulaefolia Nees., mistakes in printing or enties? … about L. lavendulaefolia Nees … please refer to this post where … has shed light. I agree to both … and … that it is Leucas lavandulifolia. Thank you very much for confirming the ID. … is superb, nothing escapes his scrutiny 🙂
Found the post about names at – efi thread Thanks for updating me on the species. My observations are based on the photographs / references available from the web and I do not have any books on flora(s). In this connection I wish to add that I am not a professional practicing taxonomist, though I studied taxonomy during my post-graduation decades ago. My knowledge is limited to local urban flora as I look out for the plants in my neighborhood as an hobby. My approach is not deep and can only suggest or point out to certain species, which need to be verified and authenticated by the professional taxonomist(s) in the group. Leucas lavandulifolia Sm(= Leucas linifolia (Roth) Spreng)- Leaves glabrous, calyx tube mouth oblique, no linear bracts. This is used for pooja in the south, leaves used in medicine; In Karnataka the leaves are used in cooking. . QUERY: Leucas: lavandulifolia AND lavandulaefolia: The author of binomial is Sm. and not Rees. (Please let me know where you found Rees; Rees was author of Publication (Encyclopedia-Cycl.) where this species was published.
as for as -ae and -i are concerned, the recent ruling of code requires that ‘ae’ in the epithet should be changed to ‘i’ routinely. Many thanks … for resolving my query. The Plant List entry of this species on clicking TROPICOS below leads to this entry
The reason that author of publication is Rees, and Smith the author of this binomial published in former’r publication must have led to this confusion.

Req. Leucas Species for ID: This is the Common Leucas [Leucas aspera]. My sightings of Leucas lavandulifolia need validation. Leucas lavandulifolia Sm. (syn. Leucas indica (L.) Vatke [Illegitimate])
Leucas zeylanica var. zeylanica (syn. Leucas indica (L.) R.Br. ex Sm.) Synonyms referred from The Plants List Leucas aspera (Willd.) Link should have (ref. FoC) –
This species is not Leucas aspera (Willd.) Link.
This species is L. lavandulifolia Smith.
Leucas aspera (Willd.) Link should have (ref. FoC) –

Three species can be confused with are L. aspera (Wiild.) Link; L. zeylanica (L.) R. Br. and L. lavandulifolia Smith.
This species has calyx mouth very oblique and largest upper tooth, so this is also L. lavandulifolia Smith.

Lamiaceae (inc. Verbenaceae) Fortnight: Lamiaceae – Leucas aspera (Willd.) Link Assam – KD 11 MAY 2015 : 12 posts by 8 authors. Attachments (5) Yes …, I know at least this species. I am afraid this is not L. aspera (Willd.) Link. At least the Oblique calyx, leaves, floral clusters all suggest L. aspera. It would help if Surajit ji gives reasons for his doubt. If this is Leucas aspera then the one I have, photographed and submitted twice in the same thread, identified by …, is not Leucas aspera. These repeat episodes are meant for this purpose only, rechecking and improving upon identifications. Your first plant earlier identified as L. aspera I think is L. ciliata (I have written in that thread also) with very long calyx lobes, strongly hispid. Your L. lavandaefolia I think is very distinct in lacking long hairs on calyx and upper calyx lobe being much longer than others as also very weakly crenate repand leaves. Actually the Leucas group for India is done by Dr. V. Singh. Dr. Sunoj also worked for Peninsular India. The former published Leucas of India in J Econ Taxon Bot Addl series. I have checked the keys in V. Singh’s work and found … provided characters are tallying mainly the size of the calyx lobe and indumentum characters important to distinguish this species.
Better follow what … provided key characters. I am totally confused.
As per Flora of China (my only latest source of information are these efloras, and I have been told by Gurcharan Sir that we can rely on them mostly ) :-
plants hispid, calyx slightly oblique at mouth……… = KEY 7
there are two species under KEY-7 = L. aspera & L. zeylanica.
FoC thinks, in L. aspera, calyx tubular……. slightly hispid or sub-glabrous at base, otherwise densely hispid outside, mouth oblique… teeth straight … apex spinescent
There are many pics of L. aspera in the net, I am not to judge who is correct and who is not, one person, from Indonesia, follows the above description – https://www.flickr.com/photos/87453322, I think.
I am really sorry that I have failed and I still fail to see the above features in the set of photographs submitted in this thread.
I will deal with Leucas ciliata in my own thread.
As I said I am very much confused. I am not sure if I should accept the ID of this species as Leucas aspera or I should wait for another repeat episode.
Thank you all for your kind teaching. Backed by three (maybe four) heavyweights it must be Leucas aspera (Willd.) Link. whether I accept or not! Please go ahead with the ID. I have to say I think this is Leucas lavandulifolia Smith syn. Leucas linifolia (Roth) Sprengel.

what are the key features that differentiate the two, … …, thank you for pointing this out.
…, I am pasting an earlier discussion below.
The calyx here (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.
Looking similar to L. aspera in appearance but easily separated by less hairy stem and leaves, leaves remotely crenate, calyx tube faintly ribbed, pubescent, limb distinctly oblique with upper tooth much larger than others which are insignificant. Verticillasters are less dense In L. aspera stem is hispid, leaves crenale, calyx tube glabrous in basal part hispid in upper, limb slightly oblique with distinct sharp teeth, verticillasters very dense almost globose.

Okey sir. L. aspera Thanks, …, But teeth are different in Leucas aspera
Sir. Yes, I was also confused. but I hope teeth number is 10, and assumed it is aspera. But calyx teeth nature shows it to be lavandulifolia. (upper teeth). Could you give photo of calyx enlarged. Forwarding another closer image. This picture shows it to be L. lavandulifolia. Thanks … I will go with the ID suggested by … & you.   MS/ID/AUGUST/2020/10 – ID of Leucas spes. : 10 posts by 3 authors. Attachments (2)- 3 mb each. 2 more photographs Leucas zeylanica (L.) W.T.Aiton?? I think more close to Leucas lavandulifolia rather than Leucas zeylanica Thanks … Can you please point out the key identification characters to differentiate it from L.zeylanica. The calyx here (Leucas lavandulifolia) is characteristically very oblique at apex, 8-toothed; teeth irregular/ minute and the posterior teeth is the largest.
It is not so in Leucas zeylanica
There are other differences too. Many species look alike and difficult to differentiate. Hence, it would be helpful if somebody in the group prepares a comprehensive key for identification of all the species of Leaucas. Yes, …
I am trying my best to put photographic keys in the form of comparative images (which are generally more helpful compared to keys in words). However, I am also trying to add word keys where ever possible and as and when time permits.
Others are most welcome to join me in this endeavour.
