Regarding the periods of the vegetation of wheat (Tri- 

 ticum vulgar e hybernum), we find in Damn's work (1. c. 

 p. 347), the following observations made in the year 1842: 



Average period of Sowing. Time of Harvest. 

 Malta . . Dec. 1 . . . . May 13 . . 164 days 

 Sicily . . Dec. 1 . (Palermo) May 20 . . 171 

 Naples . . Nov. 16 . . . . June 2 . . 195 

 Rome . . Nov. 1 .... July 2 . . 242 

 Berlin . . 299 



Link read some observations upon the vegetation of 

 Dalmatia, before the Geographical Society of Berlin (Mo- 

 natsberichte, Bd. 2). 



Visiani has had individual plants of Greece and Asia 

 Minor drawn, from Parolini's collections (Memorie dell' 

 Institute Veneto, vol. i, 1843) : 6 of theLabiatae (Thymus, 

 Stachys), 2 Boragineae (AncJmsa, Lycopsis), Dianthm 

 Webbianus and Sedum Listonia. The new species which 

 he has there proposed had in part, however, been pre- 

 viously described elsewhere. 



II. ASIA. 



Parts 11 18 of the ' Illustrationes plantarum orien- 

 talium' of Gr. Jaubert and Spach (see Ann. Rep. for 

 1843) have appeared (Paris, 1844-45). The following 

 families and genera are described in detail : Polygoneae, 

 Asarineae, Chenopodeae, Legurninosse, principally Ge- 

 nisteae (including G. gracilis, t. 143 = G. carinalis, m.), 

 Cousmia. In Lorent's oriental travels (Wanderungen 

 im Morgenlande. Mannheim, 1845, 8vo), 35 species are 

 described by Hochstetter as new, most of them from 

 Syria and Armenia. Endlicher and Diesing have de- 

 scribed 6 Algae which were collected by Kotschy in the 

 Persian Gulf (Bot. Zeit. 1845, p. 268). 



Mahlmann has elaborated Chanykoff's observations on
