Curysanruemum Catananche, Ball in Trimen. Journ. Bot., 1873, p. 366. 
This, which is one of the most beautiful plants of the 
Greater Atlas, was discovered in 1871, by Messrs. Ball, 
Maw, and myself, in valleys of that range at elevations of 
7000 to 9000 feet, flowermg in May, and has since been 
cultivated both in Mr. Maw’s garden, and at Kew, where 
it flowered for the first time in April of the present year. 
In its native country it forms patches of a silvery green hue, 
and of considerable size, in rocky valleys, and on mountain 
slopes exposed to the sun. ‘The broad white involucral 
bracts are conspicuous for their silvery whiteness, hyaline 
texture, and transparency, relieved by a narrow purplish 
herbaceous central band; their resemblance to the bracts of 
Catananche has suggested the specific name. 
Descr. Rootstock stout, woody, branched, with often many 
heads. Leaves tufted, one to two and a half inches long, as 
well as the scape clothed with silky tomentum of a silvery 
green colour, petioled, irregularly 3-chotomously cut 
once twice or thrice into linear acute or obtuse spreading 
lobes; petiole slender, narrow. Scapes stout, ascending, 
three to six inches high, green. Heads solitary, one and a 
half to two inches across, pale yellow, the rays of dirty
