HORTUS GRAMINEUS WOBURNENSIS. 163 



and, after making due allowance for the state of the weather, the 

 third week in May, and the first week of August to September, 

 were evidently the best. 



It flowers in the first and often in the second week of July, and 

 ripens the seed in the beginning of August. 



HOLCUS lanatus. Woolly Soft-grass. 



Specific character : Root fibrous ; calyx woolly ; lower floret per- 

 fect, awnless, upper with an arched awn ; leaves downy on 

 both sides. Sm. Engl. Fl. i. p. 107. 



Fig. 1. Calyx magnified, shewing the dotted, hoary valves, the 

 innermost broadest. 2. The two florets, shorter than the 

 calyx. 3. Germen and slender-feathered stigmas. 



Obs. Practical farmers often mistake this grass for the 

 creeping-rooted soft-grass ; I have therefore given a figure of 

 the latter in the next following page, for the convenience of 

 comparison, otherwise it belongs to another division of the 

 subject, that is, grasses natural to sandy soils. The male, or 

 unisexual floret, contains one pistil; the germen, or rudi- 

 ment of the future seed, is similar to that of the fertile or 

 bisexual floret, but much smaller ; it is always abortive . Seed 

 with a shining hardened coat, which was formerly the corolla.
