338 Dr. Smitu’s Account of several Plants, 
Agrostis arundinacea in its flowers, not to mention the smallness 
of its leaves.” | | 
In fact, this plant is next akin to Agrostis arundinacea, and like 
that is surely an Arundo, according to Linnxus’s original deter- 
mination in the Flora Lapponica. They both belong indeed to 
the genus which some have separated from Arundo, by the bad 
name of Calamagrostis, distinguished by having only 1 floret in 
each calyx, as do likewise Arundo Calamagrostis and Agrostis 
Calamagrostis of Linneus. It seems to me that p may all very 
naturally be referred to Arundo. 
Arundo neglecta is by far the smallest British species of its ge- 
nus, being scarcely 2 feet high. It has something of the habit of 
A. Calamagrostis, but differs from that, as well as from all the 
species just mentioned, in having the glumes of the calyx simpl y 
acute, without any elongated point. ‘The corolla moreover is as 
long as the calyx; its glumes abrupt and jagged, the larger bear- 
ing a short dorsal awn, scarcely projecting beyond the calyx, and 
not, like that of Agrostis arundinacea, twice as long. "The root is 
creeping. Stem simple, with 2 joints, smooth, as are also the 
sheaths. The leaves are narrow, acute, rough on the upper 
surface and edge. Stipula very short, abrupt and entire. Panicle 
of a purplish or bronze-coloured brown. 
It must be confessed that the first grass, described in the pre- 
sent paper, comes very near these just referred to Arundo, in the 
generic character founded on the hairs at the base of the corolla. 
But the hairs of Aira levigata form a tuft at the base of the 
outer glume only, and, from the analogy of Aira caspitosa, should 
seem rather to belong to the rachis than to the glume itself, how- 
ever closely approximated to the latter. ‘They do not, as in 
Arundo, grow out of, and entirely encompass, both glumes of the 
corolla. |
