Turkestan, with the climate and many types of the vegeta- 

 tion of Western Tibet (where, however, C. Ledebouriana 

 has not hitherto been detected). It is a large rather 

 succulent species, with a tuberous root, and it must hence 

 be transferred to the section Bulbocapnos, from that of 

 Leontice, to which it has been hitherto referred, and in 

 which the root is fusiform. I am indebted for the speci- 

 men here figured to Mr. Elwes, who received it from the 

 St. Petersburg Botanical Gardens, to which it was sent by 

 Dr. A. de Kegel. The flowers generally precede the leaves, 

 and appeared in Mr. Elwes' garden in the end of February; 

 the leaves of the Kew specimen followed the flowers in 

 April. There are, however, flowering specimens in the 

 Herbarium with fully formed stem-leaves. 



Descr. Rather fleshy, quite glabrous, pale glaucous 

 green. Boot as large as an ordinary potato, depressed- 

 globose. Leaves long-petioled, irregularly ternately or 

 biternately divided ; petiole short or long ; segments one- 

 half to one inch long, obovate, entire or one- to three- 

 lobed, lobes rounded, nerves very obscure. Flowering -stems 

 ascending, six to ten inches, soft, terete, pale, tapering to 

 the base, furnished about the middle with an opposite pair 

 of trisect leaves with narrow leaflets. Raceme four to six 

 inches long, lax-flowered ; bracts large, leafy, broadly 

 elliptic, green with purple edges. Flowers shortly pedi- 

 celled, an inch long, purplish brown. Sepals very minute, 

 membranous, irregularly lobed. Lobes of the corolla dark 

 purple, small, subequal, subacute, upper straight, hardly 

 keeled, lower decurved. ' Spur twice the length of the 

 rest of the corolla, cylindric, stout, obtuse, recurved, pale.
