character will be found by an examination of the calyx, the lobes of 
which are longer and more gradually acuminate. 
23. Buddleia nivea Duthie, 1. c., p. 275, fig. 102. 
A medium-sized shrub. Branchlets, under surface of leaves and in- 
florescence densely clothed with pure white woolly pubescence; branch- 
lets cylindrical or more or less flattened at the nodes. Leaves opposite, 
petioled, 4 to 9 inches long, 11/, to 4 inches in breadth, falcately ovate- 
lanceolate, acuminate, rounded or subcuneate at the base, glabrous above 
except on the midrib, densely clothed beneath with white woolly pubes- 
cence; margins coarsely serrate, the teeth with callous tips; midrib stout; 
main lateral nerves many, spreading almost at a right angle, ultimate 
nerves forming conspicuous reticulations; petioles !/, to t/a inch long, 
grooved above. Flowers cymose on the spike-like branches of a terminal 
panicle, shortly pedicelled, or the central ones of each cluster sessile. 
Floral leaves !/, to 1 inch long, obliquely ovate-acuminate, or the upper- 
most linear; bracteoles linear, often exceeding the flowers. Calyx densely 
woolly outside, nearly glabrous within; lobes triangular, one-third the 
length of the tube. Corolla purple or lilac, 3 lin. long; tube tomentose 
outside (except at the base), glabrous within; lobes spreading, sub 
quadrate, slightly emarginate at the apex, edges undulate ciliate. Stamens 
attached to the upper part of the corolla-tube, and protected by a ring 
of white hairs. Capsula tomentose, exserted from the marcescent corolla. 
A very distinct species, easily recognised by the pure white woolly 
pubescence which clothes the under surface of the leaves and the spike- 
like branches of the inflorescence. This handsome shrub was found by 
Mr. E. H. Wilson on mountain slopes in Western Szechuan, at ele- 
vations between 7000 and 8000 feet. Its bright purple flowers are shown 
to great advantage against the white-silvery pubescence.

Gentiana ornata, its nearest ally, is a native of the Eastern Himalaya 
and South-West China. Gentiana ternifolia Franchet, is another ally which
