Bentham and Hooker estimate the number of species at five or six :—‘‘ Kurope et 
Asize temperate vel montane incole, quarum 1 vel 2 etiam in Africa Tropica et Australi 
Colombia et Mexico obvie,” from which it may be inferred that Bentham did not 
regard Fournier’s Mexican species as distinct. ‘The material, however, is too imperfect 
for us to decide the question, therefore Fournier’s species are enumerated on their 
merits.

In addition to the foregoing, S. Watson (Proc. Am. Acad. xviii. p. 183) refers a 
specimen collected by Schaffner at San Luis Potosi to B. cwspitosum, Roem. et Schult., 
which is usually regarded as a variety of the common B. pinnatum. 
Tribe XII. HORDE. . 
Hordee, Benth. et Hook. Gen. Plant. iii. pp. 1076 et 1093. 
There are twelve genera in this Tribe, and about eight species . scattered over most 
temperate regions; rare in the tropics, and a few extending to the Arctic regions, 
Four of the genera are monotypic. Loliwm perenne, Linn., and Lolium temulentum, 
Linn., are members of this Tribe colonized in Mexico.
