The plants from which this Florula has been composed were collected 
by the active De Notaris on the island Capraja (43° 0°10 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 :—
