Asteraceae Fortnight Part 2-Discoid Heads: Herb For id from Chakrata Route- NS 12 : 6 posts by 4 authors. Attachments (4)

This small herb was shot from a river bed in Chakrata area, lying unidentified for long…is this a Dichrocephala species? Please help to id…

I think it should be D. chrysanthemifolia (Blume) DC. as per images at below:
Dichrocephala chrysanthemifolia is known in Uttarakhand and this plants look like the species.

Thanks, …, for confirmation for addition of a new species

I am grateful for this id, more to see it is an addition to the database..

I think this may also be Dichrocephala integrifolia subsp. gracilis (DC.) A.Fayed as per … post at Dichrocephala integrifolia var. gracilis from near Nohradhar, Himachal Pradesh-GS010320120-3 and as per GBIF.

This will not be Dichrocephala chrysanthemifolia (Blume) DC. as per FOC illustration.

Dichrocephala integrifolia subsp. gracilis (DC.) Fayed

Synonym: D. gracilis DC.
Dichrocephala integrifolia is differentiated from other species in flat receptacle top (conical in D. chrysanthemoides, petiole base clasping) leaf base winged with no auricles at petiole base (leaf base expanded auriculate-clasping, not narrowed petiole).
Two subspecies are differentiated:
Subsp. integrifolia:  leaves are mostly undivided or very shallowly divided with 1-2 pairs of lateral lobes
Subsp. gracilis:  pinnately lobed leaves, lateral lobes 2-3 pairs, in type variety integrifolia  
Here is subsp. gracilis, clicked from near Nohradhar, Himachal Pradesh. May 24, 2015.
