Anthoocanthum odoratiim. Sweet-scented Vernal-grass. 



Specifc character : Spike, egg-oblong shaped. Florets, longer than the awns, and supported 



on short foot-stalks.

 its outside covered nearly to the top with stiff brown hairs lying flat. Stem with two 



or 



three short hairs and shining joints. Native of Britain. £. Bot. 64? ; Curt. Lond.-

The proportional value which the grass of the latter-math hears to that of the seed crop 

 nearly as 13 to 9 ; and the proportional value or nourishment contained in the autumn grass 

 exceeds that of the first grass of the spring, as 9 to 7. 



Sir H. Davy has shewn, that the nutritive matter of the grass at the time the seed is ripe, 

 consists of-mucdage, or starch, 43, saccharine matter 4, and hitter extract and salt 3 = 50. 

 The leaves, or first growth of the spring, afforded me of mucilage 40, saccharine matter 1, 

 brtter extractive 9 = 50. The bitter extractive is here much greater in the leaves, than in the 



culms and leaves combined, which is the case with all thp o-./ x i, j . -'i f ^hnnsh
