Parietaria debilis from Chakrata area:
Parietaria debilis G.Forst., Fl. Ins. Austr. 73 1786 Syn: Freirea debilis (G.Forst.) Jarm.; Freirea australis Nees
Family: Urticaceae
This small insignicant plant may be missed by many, and I had probably missed it many times till one day on collection trip to Sonamarg in Kashmir, the famous Russian authority on Salicaceae, Prof. K. Skvortsov picked up a plant from under the rock and showed it to me. I found it again in Chakrata while moving towards Deovan area and again towards Budher caves area.
A diffuse pubescent herb with numerous straggling delicate stems, often forming patches; leaves alternate, 3-nerved, 10-25 mm long, ovate to orbicular; flowers minute in axillary clusters, male with 4 stamens,
4-parted perianth; female with tubular 4-lobed perianth enclosing ovary, stigma a tuft of hairs; fruit enclosed in persistent perianth.
