Sir, I take this opportunity to correct myself - in my post<https://groups.google.com/forum/#!msg/indiantreepix/5fLT3jku9Cc/uCGaVk-ZgFUJ>i have written that there is no *Sonchus arvensis* L. in India (as per BSI<https://groups.google.com/forum/#!msg/indiantreepix/5fLT3jku9Cc/uCGaVk-ZgFUJ>). I was *wrong*. There is one -
- *Sonchus brachyotus* DC = syn. *S. arvensis* L. var. *glaber*. (there is a special note in FoC<http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=242349597>) This plant is not *S. brachyotus*, because it has *glandular* head (BSI docs). *S. oleraceous* L. has *acute auricles* (BSI) *S. asper* (L.) Hill. - 1) peduncle can have glandular hairs (BSI) 2) capitula also can feature glandular hairs (FoC<http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=200024556>). But leaves are different - http://www.plantillustrations.org/species.php?id_species=960379. *S. jainii* Chandrabose et al. - is confined to W. Ghat & Tamilnadu (BSI) So, we are left only with *S. arvensis*. Ii is *non L.* as per BSI & FoC. It was *L.* as per old classics. In volume 2 of "Botany of Bihar and Orissa" (H. H. Haines; p497) *S. arvensis* has leaves *glaucous* beneath, amplexicaul base with rounded auricles. Two varieties - 1) glandular heads - var. *typica* 2) egkandular - var. *glaber*. If we wish to follow BSI or FoC, since they are latest, then this plant is i think *Sonchus wightianus* DC. ssp. *wightianus*. But, unlike BSI descriptions the plants in my posts had glabrous stems which is a feature of *ssp. **wallichianus* *!* * * Thank you, Regards, surajit On Sat, Jul 20, 2013 at 8:22 PM, J.M.
