DC. Prodr. vi. 303 ; erect, glabrous, rarely scabrid, slender, lowest leaves small ovate petioled or 0, all or upper sessile linear-oblong obtuse or acute nearly entire deeply sagittately or broadly auricled at the base, invol. bracts shorter than the scarlet flowers, style-arms dilated at the tip, achenes glabrous. Clarke Comp. Ind. 176. E. angustifolia, DC. l. c. Cacalia angustifolia and teres, Wall. Cat. 3163, 3164.

SIKKIM HIMALAYA, alt. 2000 ft., J. D. H. KHASIA MTS., alt. 2-4000 ft. ; common. — DISTRIB. Upper Birma.

A very slender species, 1-3 ft. high, with much the habit of E. flammea, but with few or 0 radical leaves, and with glabrous achenes. I have seen but two specimens of the scabrid form; they were found by Dr. Thomson and myself near the Ongot river in Khasia.

Please help to identify this Emilia species, recorded from Meghalaya..
This may be same as Earlier Upload by Karuna Ji
Inputs requested..

emilia sonchifolia


Please Check Emilia sonchifolia Sir


Thanks … for forwarding, thanks to … for their opinion… But I am sure this cannot be Emilia sonchifolia


Eight species of Emilia are known in India as per BSI document.
E. alstonii (Karnataka)
E. exserta (Karnataka)
E. javanica (Eastern, Northern, North East and Peninsular India)
E. prenanthoidea (Eastern Himalaya and NE India)
E. ramulosa (SW Ghats)
E. scabra (NE & Paninsular India)
E. sonchifolia (Throughout India)
E. zeylanica (NE & Peninsular India).
But this species is quite interesting with no petiolate radical leaves and almost entire cauline leaves. A difficult one (due to morphological variation) or something new?
Expert opinion is needed.


Emilia prenanthoidea DC. !


Emilia prenanthoidea DC. and Emilia zeylanica C.B.Clarke are difficult to differentiate.

In this particular case presence of so much hairs on leaves are point of concern (in both cases).
  • involucral bracts about 10 equalling the flowers = pernanthoides
  • involucral bracts about 1/2 as long as the flowers = zeylanica

I think it would be E. zeylanica C.B. Clarke


I think it more closer to Emilia prenanthoidea (phyllaries 10 as per Flora of China). Pl. see long phyllaries as per GBIF– specimen. (Involucres cylindric or narrowly campanulate, 6-11 × 2-3 mm; phyllaries 10, oblong, 6-12 × 1-2 mm, shorter than florets, glabrous, margin scarious).

I did not find the description of Emilia zeylanica on net, but phyllaries appears to be less and short as per POWO and GBIF– specimen.



Thanks Sir ji, I think I should retire.


GBIF Emilia zeylanica visavis the posted plant

“Thanks, …

I think it more closer to Emilia prenanthoidea (phyllaries 10 as per Flora of China). Pl. see long phillaries as per GBIF– specimen. (Involucres cylindric or narrowly campanulate, 6-11 × 2-3 mm; phyllaries 10, oblong, 6-12 × 1-2 mm, shorter than florets, glabrous, margin scarious).”
  • This specimen of E. prenanthoidea, from Meghalaya, India, clearly shows phyllaries, except in one flower almost equal to flowers – https://www.gbif.org/occurrence/1988984976
  • In the uploaded pictures some hair can be seen on phyllaries !!! But I agree that it is ignorable because modern lenses can capture fine hairs on totally bald men heads too 😀
“I did not find the description of Emilia zeylanica on net, but phyllaries appears to be less and short as per POWO and GBIF– specimen. “
  • As per FBI both spp are almost identical – I agree that is outdated literature
  • You cannot say “…  phyllaries appears to be less and short…” = did anybody count them? did anybody take measurements?
  • Attached here is a screenshot, with modification, of the GBIF plate you referred in your above statement of E. zeylanica.

Yet, I subscribe to your and … suggestion, only because of the location of the specimen, not on a single point of your analysis.
