Obs.— There is still another variety of tlie Phkum pratense, distinct from the precedi 

 which may be mistaken for the PAfem JZO^o^M'^ •• that variety grows on poor clayey 

 particularly by road-sides. It approaches to the present species, in having the root some 

 what bulbous ; the straw is likewise ascending, but not knee-bent, as in the P/./g,,,, 

 nodosum: these characters continue constant when the plant is cultivated on different soils 

 Ci. e.J on light sandy soil, heath soil,' and tenacious clay. It is smaller in every respect 

 than the two varieties of which specimens have been given. The P. nodosum differs fro^ 

 the P. pratense, in having knee-bent culms, bulbs growing out at the root of the stem- 

 leaves, which in time become plants. Culm leaves shorter and smooth, except at the 



dges. Anthers white. The dagger-like points of the husk are also longer, and 

 reflexed than in those of the Phleum pratense.

The above details shew, that this species of Meadow Cat's-tail is much inferior even to tlie 

 lesser variety of the Phleum pratense. It is a very scarce grass, at least as far as my researches 

 have extended, having found it but in one meadow in a wild state. It grows in a clayey mi 



park, from which the annexed specimen was propagated. Hares aud 

 rabbits neglected this grass for the common Cotton-grass, (Eriophorum angustifollum) , whldi 

 grew closely adjoining. 



It flowers in the second week of July, and ripens the seed in the end of the same month; 

 but the seed is seldom good.
