HORTUS GRAMINEUS WOBURNENSIS. 377 



It flowers in the third week of June, and ripens the seed about 

 the middle and latter end of July. 



AGROSTIS ?amosissima. Lateral-branching Bent-grass. 



Specific character : Panicle spike-like, heaped ; calyx shorter 

 than the corolla; culms branching at each joint. Hort. Gram.

Obs. This is nearly allied to the Agrostis Mexicana ; the culms 

 are taller and more woody, lateral branches more numerous, 

 shorter, and pointing one way ; leaves smoother than those of 

 the A. Mexicana; panicle more compact, or heaped together, 

 which gives it more the appearance of a spike ; calyx shorter 

 than the corolla, with very few hairs at the base, which are long 

 and numerous in the Mexicana. Flowers a month later than 

 that species.

This is one of the latest flowering grasses. It is remarkable for 

 the number of branches that issue from the joints of the stem; and 

 the woody substance of the culms makes it approach to the nature 

 of a shrub. It affords little herbage till the beginning of summer, 

 and flowers at so late a period of the season, that excepting once, 

 I have never been able to procure any perfect seed, the frost ge- 

 nerally destroying the panicles before the seed is perfected. The 

 herbage is killed by frost, but the roots suffer nothing from its 

 effects. It is propagated by parting and planting the roots early 

 in the spring, or late in the autumn. The above details shew that 

 it is neither very productive nor nutritive. 



Flowers in the first or second week of October.
