WESTERN TIBET ; Baltisthan, alt. 10-14,000 ft. ; Thomson, &c. DISTRIB. Central 

 Asia, and the whole Subarctic Zone. 



Stem 4-18 in., erect, 4-lineolate or 4- angular, branches ascending. Leaves 1 'by 

 ^ in., narrowed below. Peduncle -2 in., 1-flowered, in axillary and terminal fascicles. 

 Calyx-tube i in., lobes f in., linear-spatlmlate, minutely serrulate in the Indian 

 plant. Corolla bluish or yellowish, lobes ovate mucronate shorter than the tube ; 

 basal glands obsolete. Capsule % in., oblong ; stalk ^ in. The Indian plant differs 

 from G. aurea, Linn, type, in the absence or obscurity of the glands at the base of 

 the corolla-tube, agreeing thus with G. umbeUata, Bieb. This character considered 

 by Grisebach as of sectional value is probably hardly specific. 



VAR. holosteoides ; height ^3 in., umbellate character of the inflorescence obscured.

 with Kotschy's.

Stem 3-12 in., 4-lineolate, branches ascending. Leaves 1 by ^ in., base hardly 

 narrowed. Pedicels 0-1 in., mostly cymose on axillary peduncles. Calyx-tube ^ in., 

 lobes i by in. Corolla pink-purple ; tube 3- in. ; lobes | in., ovate, mucronate. 

 Capsule % in., narrowly oblong ; stalk ^ in. This has the habit of G. aurea.
