of the midribs, and gives to the spicula of this genus, as I understand it, an 
appearance very different from that which we find in AcHNopon. Gaudin 
and Kunth describe a subulate rudiment to several species, but except in 
P. Michelii Y have not been able to detect it. In Phleum Gerardi of Villars 
I can discern no inner palea; and I think in habit as well as in the dorsal 
awn of the palea it agrees better with Alopecurus than with Phleum. 
ALoPECURUs. In some species of this genus the glumes are united at the 
base, and in some the inner edges of the single palea are united so as to form 
a tubular corolla, but neither of these characters runs through the genus. 
Crypsis is placed by Kunth among the Phalarideæ, and its dense panicle has 
obliged me to place it here, but its comparatively large and firm paleze might 
perhaps vindicate for it a station among the Agrostideæ. These tribes, how- 
ever, are so closely allied that I have more than once doubted the propriety of 
keeping them separate. The thin paleze and dense spike unite in inducing me 
to transfer Gasrripium from the Agrostidee to this tribe. Palisot de Beauvois, 
indeed, ascribes to this genus coriaceous paleæ ; and Sir J. E. Smith by his 
remarks on Milium, with which he unites it, seems to hold the same opinion. 
I find, however, the palez of both species to be as described by Kunth * te- 
nuiter membranacee,” and that in all stages. 
Some species of Polypogon might seem to belong to this tribe, 
but we cannot 
divide the genus. 
The comparatively strong geniculate and twisted dorsal 
awn of Lagurus, with the two lengthened points of the outer palea, show it 
to belong to the Avenaceæ.
