29092011GS1 from Nandni (J & K) and Mussoorie Chakrata road for ID:   This plant I had photographed from near Nandini (closer to Udhampur) in J&K on 22 August this year and again on 16 September from Mussoorie Chakrata road near Kalsi. In Nandini I found only plants with divided leaves, where as in Chakrata route both with divided and almost entire leaves. The plant grows to height of about 50 cm or more, erect or slightly ascending, leaves up to 5 cm long, divided into lanceolate-oblong segments or barely toothed; heads are yellow about 3-4 mm across, with few very small ligules.
I had initially identified it provisionally as Conyza stricta from Flora simlensis, but the plant does not match one on Flowers of India and Flora of Zimbabwe, which coincidentally also do not match each other.
Please provide your inputs

The one we have here in Kalatope is like the observation from Nandini, J&K..

Saw this plant on a hilltop near Saputara, GJ in Feb 2017. Any Blumea species?
May be these pics are not enough to ID.


Pl. also check with comparative images at Blumea


Does not seem to match with any species as per comparative images at Blumea


Most probably Conyza stricta.


Thanks, …, for the Id. Yes it appears close as per images at Asteraceae Week (Part I – Radiate heads) :: Conyza stricta at Kulang ::PKA83

Something like ConyzaBlumea etc.


Erigeron trilobus (Decne.) Boiss.  ???
Syn: Conyza stricta Willd.
But Google images do not look like matching !

I also think this should be Conyza stricta..
