This much branched hardy herb was photographed from near IOCL Refinery, Panipat in May 2011. I hope this is Pluchea lanceolata (DC.) Oliv. & Hiern. Kindly correct/validate.
The height of the plant nearly 1 m, leaves alternate, lanceolate, flower heads deep pink/purple.


Yes … Commonly seen in Delhi also.


Nice one … Is it native…wild or ornamental in gardens?


The plant grows gregarious and wild in many parts of N W India, but being a useful medicinal plant it is often cultivated by drug companies.

Happy to see Pluchea lanceolata growing wild and that too as a weed. As per our study in central India, it has been estimated as near threatened. For further study, we need seeds of these plant and some exact GPS locations. So, asking for the help herewith.

Asteraceae Fortnight Part 2-Discoid Heads: Pluchea lanceolata from Panipat- NS 05 : Attachments (11).  2 posts by 2 authors.

This roadside shrub, of dry places was found growing near IOCL refinery, Panipat..
stem erect, never above 1 m, leaves lanceolate, entire, coriaceous, base slightly twisted or angled..
I hope this is Pluchea lanceolata….
Reference to my old post…
Pluchea lanceolata (DC.) C.B.Clarke is a wild shrubby member in Asteraceae. It is rather rare in Pantnagar (located in one place) just yesterday (4th June). Since I was unaware of the ID, dissected out it considering species of Vernonia but later determined it as P.lanceolata.
Interestingly, two types of tubular florets exist in the head- outer slender female florets in few rows and central few robust bisexual florets (which despite of bisexual structures act as male). Slender achenes are produced only by outer female florets.
This species known as“Rasna” is an important medicinal plant.

Pluchea lanceolata (DC.) C. B. Clarke

Syn: Berthelotia lanceolata DC.
Photographed from Delhi.
While trying to identify species of Pluchea in India we must be looking at least at seven names. The two species earlier considered distinct with winged stem due to decurrent leaf bases (P. ovalis) or without winged stems but distinctly auricled leaf bases (P. tomentosa) have now been merged into one P. ovalis.
1. Heads solitary or few, 8-12 mm across, not in corymbs; involucre bracts
subulate-lanceolate, rigid………………………………………………………………………P. arguta Boiss.
1. Heads many in compound corymbs, less than 8 mm across; outer involucre
bracts not rigid…………………………………………………………………………………….(2)    
2. Leaves sessile, decurrent on stem (to make it winged) or auricled at base; outer
involucre bracts acute……………………………………………………………………………..P. ovalis DC.
2. Leaves sessile or subsessile, neither auricled at base, nor decurrent on stem……..(3)
3. Plants of salt marshes; leaves subsessile, obovate or oblanceolate, subserrate,
often gland-dotted; outer involucre bracts rounded at tip; disc florets less than 7;
pappus white…………………………………………………………………………………………P. indica Less.
3. Plants terrestrial; leaves not gland-dotted; disc florets more than 10…………………..(4)  
4. Leaves 12-20 cm long, linear with recurved margin, nerves obscure……………………..P. linearifolia Cl.
4. Leaves shorter than 10 cm long, not linear, flat, nerves distinct…………………………..(5)
5. Tall shrub up to 2 m tall; leaves elliptic to obovate-oblong, faintly toothed, tips
not pungent; outer involucre bracts ovate, acute…………………………………………….P. wallichiana DC.
5. Low shrub mostly less than 1 m tall; leaves oblong to oblanceolate, mostly
entire, tip mucronate and pungent; outer involucre bracts oblong, obtuse,
purple at tip………………………………………………………………………………………….P. lanceolata (DC.) Cl.


Conyza paniculata Willd. is now Pluchea paniculata (Willd.) Karthik and Moorthy; which makes it another species in this genus.
