forms of C. alpinum in Bull. Soc. Nat. Mosc. 1862, p The 
geographical distribution of the various nee of the eat ores are for 
the great part taken from his memoir. The result of his exami- 
nation and comparison of these forms from East Siberia and the 
neighbouring epee of the United States is set forth with that 
critical appreciation of the relative value of mg vere ap a 
and lucidity of treatment, which both he and Max z have 
peer to bear vay so much success on the eelaieian alisutiicas

Pallas’s and Steven’s specimens hun the Crimea first referred to 
by Georgi in Beschr. Russ. Reichs. iv. 987 (1800), under the name 
of C. repens. This is La obably the plant figured by Mori ison, 
Pl. Hist. Univ. Oxoniens. iii. ‘4 22, f. 44 (1715 ). The species 
seems closely allied to C. 4 gr andiflorum, pag which it differs mae

In recent authentic specimens (4. Callier, It. Tauric. ii. . 46 
[1896] ), and in others from the Crimea, the leaves seemed to m 
to be almost acute, not obtuse, as generally stated in Gaciscoas.
