specific distinction is founded, being a most inconstant 
character in the specimens I have examined. From W. 
Kitaibelii, figured at Tab. 6188 of this work, this species 
differs conspicuously in the long involucral bracts, as also 
in the absence of accessory teeth in the sinus between the 
calyx-segments, a character omitted in the plate referred to. 
W. tenuifolia flowered in the rock-work at Kew, from 
roots received from M. Frébel of Zurich, under the name 
of Edraianthus caudatus, a species differing from this in 
the very short broad calyx-segments; it flowered in August 
of last year. 
Descor. Root stout, spindle-shaped, giving off from the 
crown a tuft of slender leaves, and several procumbent 
flowering-stems. Leaves one and a half to four inches 
long, by one-eighth of an inch wide, glabrous or hairy, 
margins with slender spinulose teeth, which are erect and 
curved inwards on the surface of the leaf. Flowering-stems 
usually shorter than the leaves, hairy or glabrate, with few 
linear leaves, which are much shorter than the radical ones. 
Heads two inches in diameter, four- to eight-flowered ; 
bracts one to one and a half inches long, linear from a 
broadly ovate or almost orbicular base, hairy, the outer 
longer than the flowers, flexuous. lowers sessile. Calya- 
tube short; segments linear, hairy. Corolla half to three- 
quarters of an inch long, narrowly campanulate, pubescent, 
pale violet-blue. Filaments broadly ovate-subulate, hairy. 
Style thickened upwards and hairy, suddenly contracted 
into a glabrous top with two short stigmas.—J. D. H.
