VAR. ? amplecfvns, Wall. Cat. 6330 ; stem obscurely quadrangular or the bases of 

 the leaves confluent and decurrent in two hairy lines, leaves nearly sessile often 

 somewhat rounded at the base. Kumaon ; Wallich. Sikkim, alt. 10,000-13,000 ft.

Except that the hairy lines down the stem are strongly marked this plant might
