Gnaphalium polycaulon Pers., Syn. Pl. 2:421 (1807) 421 1807. (Syn: Gnaphalium floccosum DC.; Gnaphalium gracillimum Perr. ex DC.; Gnaphalium multicaule Willd.

Distribution: naturalized pantropically . Leaf surfaces of different colour, upper white hairy, lower almost glabrous; basal leaves persistent at anthesis; inflorescence spicate, lower glomerules of heads often pedunculate………………………….Gamochaeta purpurea
Leaf surfaces not markedly different; basal leaves withered at anthesis; heads in spicate panicles, densely wooly 2/3 from base………………..Gamochaeta pensylvanica
It is true that the three species are very close, Gnaphalium purpureum, G. pensylvanica are shifted to genus Gamochaeta on the basis of pappus being connate at the base, whereas in Gnaphalium they are free at base and fall individually.
A feature that separates Gnaphalium purpureum in addition to free pappus hairs is that heads form an elongated spike each cluster not subtended by ordinary leaves. To that extent your plant may be G. polycaulon.

This is what Flora of China writes about Gnaphalium polycaulon
“Similar to Gamochaeta pensylvanica, this species differs by its more compact habit, oblanceolate leaves, and free, separately deciduous pappus bristles more dilated at apex.” .

Very good photographs … .
… ID please.
Place: at top of Ratangad (~ 754 m / 2473 ft asl), near Bhandardara, Maharshtra. It is Gamochaeta (formerly Gnaphalium), probably G. purpureum or G. pensylvanicum (American weed, often confused with G. purpureum, recently become common in Delhi and other parts of India). Here is how you can separate them
Leaf surfaces of different colour, upper white hairy, lower almost glabrous; basal leaves persistent at anthesis; inflorescence spicate, lower glomerules of heads often pedunculate……………………………………….G. purpurea
Leaf surfaces not markedly different; basal leaves withered at anthesis; heads in spicate panicles, densely wooly 2/3 from base………………..G. pensylvanica Many many thanks … for this help with ID. Looking at leaves in your plant being more greener on upper surface and distinctly whitish on lower and lax low clusters your plant may be G. purpurea. Here is my G. pensylvanica Looking through books of Shrikant ji for Gnaphalium … the Further Flowers of Sahyadri illustrates Gnaphalium polycaulon Pers. and Gnaphalium luteo-album. It is true that the three species are very close, Gnaphalium purpureum, G. pensylvanica are shifted to genus Gamochaeta on the basis of pappus being connate at the base, whereas in Gnaphalium they are free at base and fall individually.
A feature that separates Gnaphalium purpureum in addition to free pappus hairs is that heads form an elongated spike each cluster not subtended by ordinary leaves. To that extent your plant may be G. polycaulon.

Perhaps checking pappus hairs may be conclusive.
I am attaching photograph of pappus hairs of Gamochaeta pensylvanica for comparison
OK, many thanks … will keep an eye open to get this aspect covered during next sighting. .
Asteraceae Fortnight Part 2-Discoid Heads: Gnaphalium from Chakrata for id- NS 62 : Attachments (3). I am closing my uploads for this fortnight with a species shot from Chakrata region…
Gnaphalium polycaulon Pers. ?? Thanks, … Yes, appears close to Gnaphalium polycaulon Pers. as per images and details herein. Only doubt is that it is being found at such a higher elevation. efloras generally mention Tropical and subtropical Asia.
I also checked many other species reported in India in Flora of Pakistan and those listed in BSI Flora of India, but looked different as per GBIF links:
I thankfully appreciate the efforts of …, for keenly looking up my old posts, and providing valuable inputs.. It is my pleasure … and a way of learning as well.
I appreciate your kind words always which encourages me more to delve into this field. I am happy I have been able to secure a small position in this field from null.

Id-23022012-PR-2: Plants from North Gujarat I think Gnaphalium sp Gnaphalium polycaulon Pers. ?? . Herb ID request – RK84 – 7-Jan-2013: Requesting identification of this herb growing on the floor in Tungareshwer. The leaves are covered with fine white hair and there is no reticulation on the leaves. Is it Gnephalium polycaulon ? its Gnaphalium sure Gnaphalium polycaulon Pers. looks close. .

   Small Plant for ID : Nasik : 20JAN21 : AK-18
3 images. A small wild plant seen a couple of days ago (20.1.21) Gamochaeta pensylvanica (Willd.) Cabrera ??
Pl. post high resolution images as I can not see the details.
Here they are..
3 high resolution images.
I think this will be Gnaphalium polycaulon as per images and references herein.
Agree with Gnaphalium polycaulon.
