Allied to M. capillaris of North America, in the form of the locustæ ; but a very different species, and, I
t.biiik, decidedly of the genus Miihlenbergia. The rigidity of the arista is quite Hke that of Stiya, as is the harsh
foUage, while in other respects the plant has more affinity with the Agrostideæ.

I Lave compai-ed this grass most carefuEy with authentic specimens of A . tenuifoUa from Persia and the Caucasus,
without being able to detect any further difference than in the size of the locustæ, which in the Antai-ctic plant are 4 of
an inch long, the Caucasian scarcely Intermediate between them is a common Eocky Mountain species, coUected
by Douglas, and described a srt. exarata, /3., in the ‘ Flora BoreaU-Americana ’ (vol. a. p. 239). There ai-e, however,
two forms of A. exarata fi., one from the east side of the Bocky Mountains, which has the scabrid broéder leaveé
of the true A . exarata. aud a distinct upper palea (this is the A. Brummondi, Torrey MS.). the other (or Douglas’s),
from the west side of the dividing ridge, is smaUer, more slender, with smaU locustæ. and no upper palea; it agreeé
closely with the MageUanic plant in size and foUage, and hears the name of rt. tmuifoliat Bleb., appended to it by
Dr. Toirey.
The crdms of rt. tenuifoUa f!. are 15 inches to 24 feet long, smooth, erect, and very slender. leaves snbseta-
ceous, obscurely scabrid. Lower palea truncate, 4-toothed and 4-nerved, with or without a short dorsal awn.
Upper palea none, or when present extremely short.

The lower palea in my specimens is obscurely 4-nerved. or, in var. /S.. 5-nervcd, with occasionaUy a very short
awn, never projecting beyond the glumes. The upper palea is one third shorter than the lower. This grass forms
a very good pasturage, both in the upland and lowland districts about Port Louis, but is not very abundant, which
it may become if it be an introduced plant. Toe sax. stolonifera is the famous ‘ Florin grass,’ or ‘ Sqnitoh’ of
Dr. Eichardson and the Irish agriculturists.
