82 THE GENUS CROCUS. 



alpine valley of Djimel, Lazistan, where he found it in flower as early as July. 

 From the Koulak Dagh and Kroom Dagh mountains I have had the pleasure of 

 introducing this species to cultivation, through the kind offices of Mr. A. Biliotti, 

 Her Majesty's Consul at Trebizond, who has on several occasions sent me liberal 

 supplies of the living corms, intermixed with those of C. Scharojani. Pavilion 

 collected the var. Suwarrowianus on the Teck Dagh, near Erzeroum, at elevations 

 of from six thousand to six thousand five hundred feet; and to Mr. James Zohrab, 

 Her Majesty's Consul at Erzeroum, I am indebted for living corms from the 

 Palan-ducken range, near Erzeroum. Monsieur Boissier records its occurrence at 

 Letschkum, Ossetia (C. Koch), Alagir, and Radscha (Rupreclit), in the Caucasus. 



Crocus vallicola is one of the earliest autumnal species: it appears above ground 

 with a remarkably rapid growth about the middle of August. The large pale 

 cream-coloured flowers, produced without leaves which are developed in the 

 ensuing spring, are very fugacious, lasting only three or four days. The flowers 

 of the type form are over early in September, and are succeeded by those of the 

 variety Suwarrowianus which last into October. 



The species when once established is easy of cultivation, and is most attractive 

 for the decoration of the rock garden or herbaceous border.
