Galinsoga parviflora: upper part of the stem not hairy or with short and sparse simple hairs
Galinsoga quadriradiata: upper part of the stem with glandular hairs and dense simple hairs
Galinsoga quadriradiata is a species of flowering plant in the daisy family which is known by several common names, including shaggy soldier, hairy galinsoga, and fringed quickweed. It is found throughout most of the temperate world, but apparently its native home is Mexico. In Portuguese-speaking countries where it is widely naturalized – e.g. in Brazil – it is known as botão-de-ouro.
As an agricultural weed it can reduce crop yields by up to 50%.[1]
This is an annual herb which varies in appearance. The main stem reaches anywhere from 10 to 60 centimeters in height and may branch or not. The petioled leaves are oval and serrated and are covered in a coat of soft hairs. The small flower heads are up to a centimeter wide and have rounded center filled with many disc florets usually in a shade of bright yellow. There are five white ray florets widely spaced around the center, each an oval shape with one or two deep notches in the end. The fruit is a small achene with a large pappus.

Family: Asteraceae Looks like Tridax procumbens Looks more like Galinsoga sp.. Check for Galinsoga quadriradiata.. Thank you very much sir. Is it an exotic or a native species?
This is the key given by …: Galinsoga Ruiz & Pavon has two species in India which are differentiated as follows (based on Chowdhery 1995 in Flora of India Vol-12):
Stems densely glandular hairy; ray florets 5-8mm, pales of the disc florets entire; pappus scale awn tipped………G.quadriradiata
Stems glabrescent; ray florets not exceeding 4mm; pales of the disc floret 2-3fid; pappus scale not awn tipped .. G.parviflora

I think Galinsoga quadriradiata as per details and keys herein and as per comparative images at Galinsoga not sure of its exact id but if it is Galinsoga parviflora Cav. how does something from peru get into indian wilds.
i would like to know if any body has any report of it having been brought to india from the Kew
where it was once known as Kew weed?
Secondly, how wide spread is it in Kalimpong area? what native plants would it have replaced/displaced http://www.flowersofindia.Quick%20Weed.html ??? I see … write that its naturalize dth eworld over. I wonder how did it get there ? that was my question So which one is this ? Galinsoga species. This is seen in many places here. You need to compare all the characters to pinpoint the ID. Comparative images in the NET are confusing. Thanks, … In efi, we have keys as well comparative images as in my reply.

Asteraceae Fortnight Part I-Radiate Heads: Galinsoga parviflora? from Shimla and Gori Valley- NS 53 : 3 correct images. 7 posts by 5 authors. Yes Galinsoga parviflora without any doubt. These specimens show considerable variability in size of ray florets, hairiness, serration of leaf margins; must be a mix of two species.
Galinsoga Ruiz & Pavon has two species in India which are differentiated as follows (based on Chowdhery 1995 in Flora of India Vol-12):
Stems densely glandular hairy; ray florets 5-8mm, pales of the disc florets entire; pappus scale awn tipped ……. G.quadriradiata
Stems glabrescent; ray florets not exceeding 4mm; pales of the disc floret 2-3fid; pappus scale not awn tipped ….. G.parviflora
Both of these occur together. To me the pics from Shimla may be G.quadriradiata but without specimens difficult to determine. In 2nd, 3rd and 6th image, though not clear, hairs on the upper part of the stem appears to have glandular & dense simple, so these may be Galinsoga quadriradiata as per keys herein.

A weed seen growing wild in the garden on 25/11/13. Is it Tridax procumbens? Resemble to Galinsoga parviflora. May be a different species of Galinsoga. It is not Tridax procumbens. Thanks again … The stalks seemed shorter, not long as in Tridax. Thats the reason I put it up for id. I think yes Galinsoga parviflora Thanks for this id confirmation too On going through Differences between Galinsoga quadriradiata & Galinsoga parviflora, I feel it may be Galinsoga quadriradiata Hairs soft in G. parviflora vs stiff bristly in G. quadriradiata.

Kindly identify this ground cover with white and yellow compound flowers photographed in Sikkim in May 2015. Pl. check Tridax procumbens Thank you … Quite a common weed, which i should have identified. I did think that this is an invasive, which has been confirmed. agree with … I think more closer to Galinsoga parviflora I agree with you. G. parviflora. Though details are not clear, on going through Differences between Galinsoga quadriradiata & Galinsoga parviflora, I feel it may be Galinsoga quadriradiata

I photographed these tiny flowers this evening on my phone thinking them to be Tridax Daisies (though they looked too small). Could these be Galingosa parviflora? Leaves were covered in long white hair. Please advise.

Yes …, it is Galinsoga parviflora………. We take it as Galinsoga parviflora for present, but I request young researchers to be on look out for possible occurrence of G. quadriradiata in India. This Mexican species is fast spreading elsewhere: Thank you … I will visit the plants with my camera soon and have a closer look. I will also collect a couple of heads and report back the observed characteristics.
I brought a sample with 3-4 flower heads yesterday evening and looked under the microscope. The flower is too small to reveal its inner parts properly with my inadequate equipment. I am not able to make out much from these images but perhaps I am not looking properly. Please advise. 7 images.

Habitat: Wild Galinsoga parviflora is a very common weed in Srinagar and perhaps most of Kashmir today. It is perhaps the second alien species which is outcompeting the local weeds as it has spread widely over the past two decades. The first alien species to do so was Conyzia canadensis which in late 1950’s (the earliest time I can remember) was already so well established that it even had a local name “Shal-e- Lot” meaning Foxtail. I suspect that another American invasive plant Symphyotrichum subulatum is well on its way to becoming the third problem species here as a few years back it was rarely seen but is now quite common. Some scientists at the Botany Department of Kashmir University have attributed the invasiveness of Conyzia to epigenetic modifications. The same may be true for these two also. Unfortunately these invasive plants are neither ornamental nor good pot herbs. Kathmandu should be prepared to welcome an unwelcome visitor. can your plant be G. quadriradiata?, densely hairy stems and leaves and larger ray florets. . 587 ID wild plant: 11 high res. images. I guess it should be Galinsoga quadriradiata Ruiz & Pav. Yes, it is Galinsoga quadriradiata dear …, and it’s pedicle and calyx are glandular hairy. Thank you very much for ID my plant
