Dear Friends,

While I was on my way to school yesterday I found this wild herb on the roadside inside a village. Within a 50 mt. span there were about 10 to 12 of them.
A search in the net gave me a post by Alok ji at - http://groups.google.com/group/indiantreepix/browse_thread/thread/6fbe1f95c9f83282/670022b86cf092d6?lnk=gst&q=Kalatope+id+Compositae# ....where Gurcharan Sir suggested "Crepis foetida" for the species posted by Alok Sir.

Could it be that "Crepis foetida" from Compositae family?

Thank you & Regards

Surajit Koley

Sir,

Thank you & Good Morning.

I am getting more confused with Sonchus, Crepis and Taraxacum. But, it appears to me now that it is closer to Sonchus sp. as Balkar Sir and Rajkumar Sir suggested.

Regards,

Surajit Koley

Sir,
I wanted to confirm if all the photographs are of the same plant or two different plants as the first three plant photos seem to have a different habit and resemble Sonchus wightianus DC. while the rest of them are S. arvense as Gursharan sir has mentioned.
Regards Gunjan

Thank you Gurcharan Sir and Gunjan ji.

After returning home when I checked those photographs (before posting) I too was confused, thinking that I have shot two different species of Sonchus. I examined the original photos thoroughly and concluded that all were same. However, again I will visit the place tomorrow and watch the plant more carefully. Certainly will inform you if I find any discrepancies out there.

Regards,

Surajit Koley

Sir,

I checked the plant this morning once again and confirm that all images are from same species, but not from the same individual plant.

I noticed 3 types of leaf blades and two types of buds.

The Bengali name given to *Sonchus arvensis* is 'BAN PALANG' (Plant Groups by H Mukherji). A website also refers it - http://www.mpbd.info/plants/sonchus-wightianus.php

Thank you & Regards,

Surajit Koley
