14082011-BS-001: cycas sp for id from Arya PG College Panipat:
A sp of Cycas i think for id
Brought from a Nursery in Panipat now in My College Never seen anywhere else (Panipat 200 mts)
Fronds about 20-25 inch spines on margins. leaflets about 4-5 inches
no cone seen
It could be Dioon edule (or another similar Dioon)
Not Cycas but Dioon spinulosum or edule may be.
This attachment could be of some use.
a few more pics of same plant
I stick to my original comment – probably Dioon edule. Cones would be needed to be certain.
Thanks … i will try to see Cones also
