Florae Marmaricae " {Bull. Herb. Boissier, i., 1893). The 

 enumeration following below is intended merely as "addenda" to 

 their valuable paper, and for convenience the form and arrange- 

 ment there adopted is adhered to, as well as their abbreviations, 

 viz. : — 



S. & A. : Schweinfurth & Ascherson, Primitiae Florae Mar- 

 maricae, in Bulletin de VHerbier Boissier, vol. i., pp. 433-449 

 584-603, 644-682, t. xx. 



A. & S. : Ascherson & Schweinfurth, Illustration de la Flore 

 de l'Egypt, in Mem. de VInst. Egypt, vol. ii., pp. 25-260. 



B. : Boissier, Flora Orientals, vols. i.-v. 



A at the end of the line indicates that the plant also occurs in 

 Egypt ; C, that it has been found in the Oyrenaica. 



The species recorded for the first time from the Marmarica are 

 marked with an asterisk (*). 



Concerning the general conditions of the vegetation of the 

 Marmarica, I would refer to the very interesting sketch of the 

 phytogeography of the district in the first part of Schweinfurth 

 and Ascherson s paper. Unfortunately there are no notes with 

 either collection which would throw fresh light on the physio- 

 gnomy or ecology of the vegetation. The additions are therefore 

 of interest mainly in as far as they extend our knowledge of the 

 constitution of the flora of the Marmarica.
