The plants from which this Florula has heen composed were collected 

 by the active De Notaris on the island Capraja (43° O'lO N. lat. 7° 

 29*55 east long. Par. meridian : 16 geographical miles in circumfe- 

 rence), on occasion of a second journey through Sardinia. The Pha- 

 nerogamia have been worked out by Prof. Moris ; the Cryptogamia 

 exclusively described by De Notaris, who has thus boldly entered the 

 field of Algologists. On the whole, there are 466 species for the 

 first section, 245 species for the second. The following are new : —
