ALOPECURUS. 



Calyx. Gluma 2 valves, containing l floret. Valves egg- 

 spear-shaped, compressed, equal, united at the base. 



Corolla. 1 valve, egg-spear-shaped, concave, rather shorter 

 than the calyx, its edges united at the base. Awn twice as 

 long as the corolla, jointed, fixed on the back of the corolla 

 towards its base. 

 Nectarium, none. 



Stamina. Filaments 3, hair-like, flattish at the bottom, 

 longer than the calyx. Anther* forked at each end. 



Pistilla. Germen roundish. Styles 2, hair-like, united at 

 the base, longer than the calyx. Stigmata woolly. 



Pericarpium, none; the blossom enclosing the seed. 



Seed egg-shaped, covered. 



N. B. In Alop. agrestis the calyx is of one piece, divided 



rather more than halfway down. Alop. monospelicensis andpa- 



niceus have 2-valved corollse. 



AGROSTIS. 



Calyx. Gluma 2 valves, enclosing 1 floret, tapering to a point

 Stigmata set lengthways with stiff hairs. 



Pericarpium. The corolla adheres to the seed without open-

Seed single ; cylindrical, but tapering towards each end. 



N. B. Scopoli says the Agrostis capillaris has only one petal ; 



but with us it has 2, though the smaller one, from its minute-
