Asia, and the whole Subarctic Zone. . 
_ Stem 4-18 in., erect, 4-lineolate or 4-angular, branches ascending. Leaves 1 by 
3 in., narrowed below. Peduncle 4-2 in., 1-flowered, in axillary and terminal fascicles. 
Calyz-tube 3X. in., lobes i in. linear-spathulate, minutely serrulate in the Indian 
plant. Corolla bluish or yellowish, lobes ovate mucronate shorter than the tube; 
basal glands obsolete. Capsule } in., oblong; stalk à 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. umbellata, Bieb. This character considered 
by Grisebach as of sectional value is probably hardly specific. 
Van. holosteoides ; height 1-3 in., umbellate character of the inflorescence obscured.
