caly cinalis of some writers, the legmen of Palisot de Beauvois, 

 the lepicena of Richard, the ccetonium of Trinius, and, finally, 

 the peristachyum of Panzer. Above the glumes are several 

 florets sitting in denticulations of the rachis (fig. 67. c): each 

 of these consists of one bract, with the midrib quitting the 

 blade a little below the apex, and elongated into a bristle 

 called the awn, beard, or arista, and of another bract facing 

 the first, with its back to the rachis, bifid at the apex, with 

 no dorsal vein, but with its edges inflexed, and a rib on each 

 side at the line of inflexion (fig. 67. a}. These bracts are the 

 corolla of Linnaeus, the calyx of Jussieu, the perianthium of 

 Brown, the gluma interior or corollina and perigonium of 

 some, the stragulum of Palisot de Beauvois, the gluma of 

 Richard, the bdle or glumella of De Candolle and Desvaux, 

 the palece of others. When the arista proceeds from the very 

 apex of the bracts, and .not from below it, it is denominated 

 in the writings of Palisot a seta. Within the last-mentioned 

 bracts, and opposite to them, are situated two extremely 

 minute, colourless fleshy scales (fig. 67. e), which are some- 

 times connate : these are named corolla by Micheli and 

 Dumortier, nectarium by Linnaeus, squamulce by Jussieu and 

 Brown, glumellae by Richard, glumellulce by Desvaux and 

 De Candolle, lodiculce by Palisot de Beauvois, and periphyllia 

 by Link. Amidst these conflicting terms it is not easy to
