There are spécimens of this plant in Herb. Calcutta received from 

 St. Petersburg in 1886; thèse were collected by D"" A. Regel al Tevildarrah 

 in the Khanate of Darwas. but I hâve also had an opporLunity of exami- 

 ning a number of examples of the same species belonging lo the St. 

 Petersburg Herbarium, including one on which Professor Regel had at 

 firsl Nvritlen the name G. dancasica afterwards subslituting, in pencil, 

 the name « C. persica » ; the spécimen in question is one of the 

 original examples of the plant described and figured by Regel under 

 the lalter name. I bave likewise examined two flowers belonging to the 

 plant preserved in the Boissier Herbarium, collected by Buhse near 

 Massula, which was in 1860 referred by Boissier and Buhse to C. nitœ- 

 folia but was transferred by the former author in 1867 to C. persica. 



The plant is not very closely related to C. persica. It would appear that 

 D"" Regel, after deciding that the species was undescribed and afler pre- 

 paring a description and figure, had come lo know that his plant was the 

 same as Buhse's .Massula plant and was therefore included in (/. persica 

 as understood by M. Boissier.lt now appears that 13'' Regel'sfirst view was 

 Sound and, under the circumstances, i hâve thought it only just to con- 

 serve his original manuscript name.
