Sonchus asper from Lohari Panipat:  Sonchus asper??
from Lohari Panipat

The more I see Sonchus species, more confused I get, especially after I uploaded what I thought true S. asper. The specimens with all type of auricles do show spiny leaves especially older plants.
  Could any member upload a really working key to differentiate S. asper and S. oleraceous?


I was trying to get differences between S asper, arvensis and oleraceous since last two-three days. What i got is the main differences is lying in their leaves as you indicated. I am now trying to collect more information
on this issue. if found any concrete thing, will share soon.



ID Assistance please: An Asteraceae, but the exact binomial eludes me

A road side/ pondside weed.


Definitely a Sonchus sp. , leaves should be there to reach to sp. id…still a guess, this can be S. oleraceous..
