Please help to identify this Asteraceae member. I have seen this in a dry scrub forest at an altitude of 1000 - 1100 msl. I could not take good photographs of it.

Location- Place, Altitude, GPS-

Satyamangalam; 1000 msl; TN

Habitat- Garden/ Urban/ Wild/ Type-

rocky dry location

Plant Habit-

tall shrub;


Up to 2.5metre

Leaves Type/ Shape/ Size-

Leaves elliptic-obovate; up to 6cm long, little scabrous

Inflorescence Type/ Size-

pale violet colored; Terminal heads of umbel; 5-8cm long

May be Pluchea lanceolata

I also hope this plant is Pluchea lanceolata (DC.) C. B. Clarke ...............

I wish to differ from Pluchea lanceolata on account of following-
1. It is not an undershrub, instead it is 2.5 tall shrub
2. Leaves are not sessile and oblong, they are petiolate and elliptic
The plant is recorded to the north of gangetic plains.
I feel that the plant is Vernonia divergens Edgew.

Mind the other characters of V.devergens i.e. Leaves in the upper branches, flowering twigs small....heads in much brached penicled corymbs....verify please

Not Pluchea lanceolata for sure, the leaves are much broader than that. I am uploading my specimens of Pluchea lanceolata.

I think it is Vernonia sp.

Not Pluchea lanceolata, because we have confirm specimen of said species.

It must be member of Vernonia?

can be Phuclea, NOT P. lanceolata. teh branches and leaves are similar to Pluchea.

it may be pluchea odorata

You seem to have got the correct identity

It does appear like Pluchea odorata.

Just a point of observation..Original photograph - leaves have short petiole. Herbarium specimen shows longer petiole.

Inflorescence in photograph looks axillary as well as terminal, while in the herbarium sheet - it looks terminal.

plz check this as Chromolaena odorata.
