Conyza? Pl. Check the spelling also.

Some Conyza or Blumea species ? 


Looks like Eclipta species. Check at the species level

Altitude is not matching with the Eclipta prostrata and did not find any match to Conyza and  Blumea.

Any idea about the genus pl.?


I could be completely wrong but my guess is Conyza

Could it be Conyza leucantha (D.Don) Ludlow & P.H.Raven  ???

May be as per images at FOI

Looks like matching but the elevation is not matching !


Still not convinced abut the ID as flower color looks

different compared to the image given in the FoI.


Link?


FOI


… Ray florets white, reduced to tube, filiform, 0.3-0.65 mm, 1/5 or less as long as pinkish style, lacerate at apex, glabrous; disk florets 6-9, yellow becoming reddish …

Thus I think it is the same species.

Conyza ???


Pl. check as per suggestions of …:


Pl. check


Pl. check with images at Conyza leucantha (D.Don) Ludlow & P.H.Raven as per comparative images at Conyza
To me appears close.  

I guess the images are matching with the earlier post but still not convinced abut the ID as flower color looks different compared to the image given in the FoI.

Pl. also check references in efi site and other resources on net.

I did check all possible options but could not get a match. I shall try again.

I think Blumea lacera (Burm.f.) DC. as per comparative images at Blumea

Is this Blumea aromatica


Thanks, … I think a little different from Blumea aromatica as per images and details herein.

I think Blumea lacera (Burm.f.) DC. as per comparative images at Blumea


I think this species is Conyza leucantha (D.Don) Ludlow & P.H.Raven.


Thanks, … Yes, you are right as per images, details and references at Conyza leucantha

.

This plant, probably a species of Blumea was photographed along Budher caves road in Chakrata. Please help in ID.


Can this be any Erigeron?


Not very sure


Conyza japonica as per another thread.

To me a looks a little different from other images at Conyza japonica


I think matches with Conyza japonica as suggested by …


Looks different from images at Conyza japonica
Neobrachyactis roylei came to my mind but it looks different as per GBIF specimens.


To me appears close to images and details at Conyza leucantha (D.Don) Ludlow & P.H.Raven

requesting id of compositae: please find attached few photos of Compositae, recorded near Saraguru, HD Kote, Karnataka.
Is it Blumea lacera?


Blumea sp.?


looks like Conyza bonariensis


I hope conyza japonica


I agree with you …, for Conyza japonica


I guess Eschenbachia japonica (Thunb.) J. KostSyn : Conyza japonica (Thunb.) DC. 

is the correct ID as suggested by …

Blumea?


Guess so.


Pl. check with images at Blumea lacera (Burm.f.) DC.


I guess leaf pattern and altitude is not matching.

Not really Conyza bonariensis, the ray florets too large for that.


I think Conyza leucantha (D.Don) Ludlow & P.H.Raven as per images and details herein.



Blumea sp (??) from Kamrup district (Metro), Assam : Attachments (13). 4 posts by 3 authors.

Attaching images of what looks like Blumea sp. (???). Please help in ID.
Date :23.07.2013
Location: Kamrup district (Metro), Assam
Family : Asteraceae
Genus & species : Blumea sp. (???)
Habitat: Grows wild on side of a drain

Habit : Herbs ( 27cm in height), height less than 1 ft.


May be Emilia sonchifolia.


Please check Blumea balsamifera (L.) DC- POWO


Yes Blumea only


Specify the species please, …


That’s too difficult to me sir exclusively in this asters, without observing complete profile,


Same degree of difficulties, if not greater, here too, Sir ji.


Myriactis wightii DC.  syn : Myriactis javanica (Blume) DC. ??

I hope the specimen is identified as Conyza leucantha (D.Don) Ludlow & P.H.Raven.


May be but I feel different !


Thanks Sir, for correcting me.


May I humbly ask to check POWO also, since basal leaves here elliptic to ovate to spatulate and capitula are very similar.


I feel more closer to images at Conyza leucantha (D.Don) Ludlow & P.H.Raven

Sending photos of some Blumea sp.
Plant about 70 cm tall, aromatic, flowers as seen in photos, annual in waste places.

Collected from Pantnagar, Uttarakhand (msl 250 mt)


I have seen similar plant in Delhi, which I have identified as Blumea laciniata.


Thanks sir for the id


Looks different from other images at Blumea sinuata (Lour.) Merr.


Appears close to images at Blumea balsamifera (L.) DC.


May I ask what are the differences in the capitula here and those in FoI specimen ?
It appears to me (I may be wrong) there is same capitulum in http://www.canbr.gov.au/cpbr/cd-keys/
What I don’t understand is how it can be same as in efi thread !!!


May I ask what are the differences in the capitula here and those in FoI specimen ?-> To me it appears different from Conyza leucantha as per images herein. Can not say about FOI.
It appears to me (I may be wrong) there is same capitulum in http://www.canbr.gov.au/cpbr/cd-keys/-> yes, phyllaries appear close. But lateral branches are creating doubt as per I did not find such at Conyza japonica (Thunb.) Less. ex DC. and GBIF
What I don’t understand is how it can be the same as in efi thread!!!-> This appears to be Conyza leucantha (D.Don) Ludlow & P.H.Raven

The posted plant appears to be Conyza and one possibility I feel is Conyza sumatrensis (Retz.) E. Walker


Sir ji, listed below are posted threads presently placed under the eFI head – Conyza leucantha :-

  1. Dinesh ji 2011 = identified 23-May-2021 by J.M. Garg = efi thread 1
  2. Shivaprakash ji 2011 = do = efi thread 2
  3. Gurcharan Sir 2013 = 29 May 2021 JM Garg = efi thread 3
  4. Saroj ji 2017 = first ID ref FoI, Oct-2017, then FoC in Jul-2018 by JM Garg = efi thread 4
  5. do = 23 May 2021 JM Garg = efi thread 5
  6. do 2018 = again 1st ref FoI then 2018 JM Garg = efi thread 5
  7. Karuna ji 2020 = identified himself in 2020 = efi thread 6
During identification of all the above threads several names of various taxa appeared, like Blumea spp …, another one is.Conyza japonica.
If FoC is referred to, as an identification tool, as it has been referred at least in the some of the above threads; the identifying points, between C. leucantha and C. japonica, should be as follows :-
  • ist checkpoint = stem viscid glandular or not = glandular equals to leucantha
  • 2nd checkpoint = cauline leaves subclasping or not = subclasping equals to japonica
As you know, I am not a professional like most of the members here, it is quite possible that I may have many wrong notion, so please correct me if I am wrong in any of the following observations (of the threads above) :-
  • none of the above posts shows glandular stem, except mohe by Saroj ji, which I think is water droplets
  • cauline leaves are all stem clasping (subclasping) in all threads except the one by Shivaprakash ji, which is not clear to me

I think examining specimens from India of Conyza leucantha (D.Don) Ludlow & P.H.Raven as per GBIF vis a vis those of Conyza japonica (Thunb.) Less. ex DC. as per GBIF, may give some more clarity.


Sorry, Sir, on the contrary, seeing GBIF specimens of C. leucantha, I am more convinced on leaf-base character. Glands cannot be seen in herbarium, so I would not comment on that. In herbarium specimen, where most of the flowers are already producing achenes, I couldn’t make out phyllaries characters.

In ray florets of C. leucantha, style(s) are pinkish (FoC) that can be seen in FoI specimen, and in Australian specimen …  which I couldn’t see in eFI specimens, except one, which may have those, but I could not find any gland there.
I have more points, but I would overlook those, because I cannot make measurements by looking at the pictures.
I didn’t study C. sumatrensis, so I would skip commenting on it.

Please, do continue with the already established ids of all threads (of C. leucantha) because this is something beyond my brain capacity.


Sir ji, did you notice that in Flora of China, flowering season of –

  1. leucantha is Sept. – Dec.
  2. japonica is Mar. – Sept.

Would it be very different in India?


Yes, in many cases elevation and flowering phenology in described in FoC and Fon in eflora are different !
Same may be in case of India !


My fault, I addressed the question wrong way. The context was Himalayan region. I will move to relevant threads when it comes to rest of India.
Never mind, when FoC says flowering season it takes account of elevation too, i think, that is why range is sometimes extended.;


I am not convinced of this being a Conyza species. I think it is closer to Blumea only. But unable to find match. Can anybody help with its id?


try Blumea axillaris (Lam.) DC.


To me it looks like Blumea axillaris only


To me it looks like Blumea axillaris only


Thanks, Sir, the id has been resolved finally.


I differ on following accounts :-

  1. At least 4 capitula in 3rd and 4th pic. show one ovate-triangular outer phyllary, with scarious margin
  2. though pictures are not clear, yet both outer and inner phyllaries seem to be narrowly scarious. As per FoC, in Blumea axillaris, outer phyllaries linear-lanceolate, and inner linear, with scarious margin
  3. the plant here is neither densely villous nor shows any glandular hair
  4. compared with KEW specimen of Blumea axillaris, phyllaries are markedly shorter than florets
  5. leaves are different and neither densely villous nor having glandular hairs (of-course the pictures are not clear)
Attached here KEW specimen of Blumea axillaris.
At the same time I admit that there can be regional variation.


Excellent analysis. Finally what is the valid ID ?


Sir ji, I don’t know yet what could be the id of this species.

As per Flora of British India (also FoC) :-
(1) Conyza belongs to ASTERAE tribe : where disc florets are yellow (rarely white)
(2) Blumea belongs to INULEAE tribe : where disc florets can be yellow, purplish, or reddish.
I am just beginning to learn asteraceae.
The leaves, here, are clearly lanceolate, the stem is woody, leaves have prominent whitish midribs, inflorescence subtended by cauline leaves.
Phyllaries, mostly, are rather lanceolate than linear.
I am inclined to Eschenbachia leucantha, based on observations at –
  1. canbr
  2. KEW – powo
  3. GBIF specimen from India – https://www.gbif.org/occurrence/2517073874
  4. High resolution GBIF from unknown location – https://www.gbif.org/occurrence/1936483432
  5. do – https://www.gbif.org/occurrence/1936483418
But, as I said I am only beginning to learn, I am open to any suggestion.


I guess … is correct !


yes, i agree with, it is Eschenbachia leucantha syn. Blumea leucantha


My main worry remains that the spread of plant and denseness of the inflorescence looks different in comparison to images at Conyza leucantha and those from specimens at GBIF. Though I get one specimen which seems quite spread out. 


7 book images.
