Campbell's Islands.] FLORA ANTARCTICA. 95 



Of this grass I have only seen immature specimens, with the panicle, however, fully formed ; it is very distinct 

 from any species with which I am acquainted, certainly wanting the' rudimentary setula of the second flower, and, 

 as far as I can observe, the upper palea also. Its habit and general appearance are decidedly those of A. Bittardieri, 

 Br. and A. cemula, Br., plants which have been removed not only from this genus, but into a separate division of 

 the Natural Order (Arundinacete) as it is now divided. These, with several other Australian and New Zealand species 

 appear to form a very natural group, though they vary in the presence or absence of the upper palea, of the setula, 

 of the awn, and of a bearded pedicel to the flower; neither the genus Lacltnagrostis (founded by Trinius) as defined 

 by Nees (Act. Acad. Cees. Leop., &c, vol. xix. Suppl. p. 146), nor Deyeuxia, Clar., as adopted by Kunth (Agrost., 

 p. 239.), will include these species. Under whatever genus they may rank, their affinity appears to me to be near 

 Agrostis, L. and not with Calamagrostk, Adans. and Arundo, L.

This is not an uncommon grass at the bases of precipices and on the exposed slopes of the island. It is re- 

 markable for being nearly allied to a species brought by Dr. Jameson from the extreme verge of vegetation on 

 Pichincha in Colombia, the A.foliata *, mihi ; that species is, however, more leafy and its whole culm is enclosed in 

 the sheathing vagina?.
