2 GRASSES OF SCOTLAND. 



Nectary (squamulse of Brown) of one or two minute, membranous 

 or fleshy scales, beneath the ovarium, either both on one side or op- 

 posite to each other, sometimes entirely wanting. 



Stamens of filaments and anthers, arising from below the ovarium ; 

 filaments long and slender ; anthers of two cells, prominent, pendu- 

 lous, forked, and divaricated at the end. 



Pistils mostly two, rarely three, and very rarely one only ; either 

 distinct or partly combined, arising mostly from the summit of the 

 ovarium ; composed of a style and stigma. Styles vastly short and 

 smooth. Stigmas rough or feathery, sometimes branched or compound. 

 Ovarium of one seed. Pericarp a thin membranous skin, covering 

 the seed, and adhering so firmly as to be scarcely distinguishable from 

 the seed. 



Albumen farinaceous, interposed between the embryo and integu- 

 ments of the seed. 



Embryo a lenticular body lying on one side of the albumen, com- 

 posed of a pumula, cotyledon, and radicle ; the pumula a conicle pro- 

 jection, inclosed in a membranous sheath of its own, fi'om whence, 

 when burst, the primary leaves of the young plant are protruded. 



The number at the commencement of each genus refers to the 

 corresponding number of the species.
