friends. Three new genera are described, viz. Maillea, to receive 

 the Phalaris crypsoides of D'Urville and Kunth ; Avellina, founded 

 upon the Bromus Michelii of Savi, which has been considered as a 

 Festuca by Kunth and Bertoloni, a Koeleria by DeCandoUe, an 

 Avena by Gussone, Trisetum by Trinius and Tenore, and a Vulpiahj 

 Reichenbach ; and Seurafalcus, intended to include the Bromi se- 

 calini of Bertoloni and Koch, the B. geninni and B. festucacei of those 

 authors being retained as the genus Bromus. As it is a point of con- 

 siderable interest to English botanists, it may be as well to point out 

 the difference between the proposed new genus and Bromus, namely, 

 Bromus, lower glume 1-nen'ed, upper 3 — 5-nerved; florets lanceo- 

 late, compressed; spikelets broader upwards; — Serrafalcus (Pari.), 

 lower glume 3 — 5-nerved, upper 7 — 9-nerved ; florets oblong, tur- 

 gid ; spikelets narrower upwards. As these characters are founded 

 upon dift"erences of considerable value in this natural order, and the 

 group thus formed is a very natural one, it is probable that the ge- 

 nus ought to be adopted, in which case the following British Bromi 

 will become species oi Serrafalcus, viz. mollis (including racemosus), 

 commutatus, secalinus, velutinus (probably a variety of the preceding), 

 arvensis (a very doubtful native), and squarrosus. It would take far 

 more space than we can afl:ord to record all the new^ species here de- 

 scribed, and we will only take the libertj^ in conclusion of expressing 

 a hope, that other botanists who publish their observations in journals 

 which rarely pass the boundaries of the countries in which they are 

 published, will follow the excellent example that has now been set 

 by Prof. Parlatore.
