Jt is not without hesitation that I refer this singular- 
looking plant to OC. glauca, from the description and plates 
of which it differs in the racemose inflorescence, the broader 
flowering calyx-lobes, and the much shorter corolla-tube 
and shorter broader corolla-lobes; but it seems nearer 
to that species than to any other, and Boissier describes 
C. glauca as varying in the length of the corolla-tube 
in relation to the calyx. The other species of the same 
section, of which four are described, all differ much more 
in various characters. The genus is a small one, confined 
to Western Asia, and extending from Armenia to Affghanis- 
tan. C. glauca is abundant in the latter country and in 
Northern Persia, ascending the mountains to 5000 feet. 
It has been cultivated in France ever since the beginning 
of this century. 
_ The specimen here figured has for some years been cul- 
tivated at Kew; it flowered in the open air in the Royal 
Gardens in 1880, and has annually since. : ;
