Series B. POACEAL. 
Poacee, Benth. et Hook. Gen. Plant. iii. p. 1076. 
Distinguished generally from the Panicacee by the pedicel being continuous (not 
articulated) below the empty glumes, the spikelet being instead usually articulated just 
within the empty glumes. 
Tribe VII. PHALARIDEA. 
Phalaridee, Benth. et Hook. Gen. Plant. iii. pp. 1076 et 1083. 
Bentham divides this tribe into two groups, the Genuine and the Pseudoryzew. The 
former consist of the southern genera Khrharta, Microlena, and Tetrarhena, and the 
more familiar Phalaris, Anthoxanthum, and Hierochloe—comprising together between 
fifty and sixty species. The Pseudoryzee consist of the two monotypic Mediterranean 
genera Crypsis and Cornucopie, and Alopecurus, of which there are about twenty 
species, indigenous in Europe and temperate Asia. 
43, PHALARIS. 
Phalaris, Linn. Gen. Plant. n. 42; Benth. et Hook. Gen. Plant. ui. p. 1138. 
There are about ten species, inhabiting the Mediterranean region, from the Canary 
Islands to Afghanistan and extratropical North and South America; and two of the 
European species are now widely colonized, including P. minor, Retz., in Mexico. This 
is very near the common North- and South-American P. intermedia, Bosc.
