Trifolium flavulum. Pale green and glaucescent, stoutish, 

 often larger than the last (the branches not rarely 2 feet 

 long), but heads not half as large: leaflets | to | inch long, 

 broadly obovate, from pectinate-denticulate to entire: heads 

 i to 1 inch broad, 5 to 12-flowered: flower seldom I inch long: 

 calyx-tube a line long, the shortest of the teeth decidedly 

 longer, the 3 lower about twice as long, all slender-subulate 



from a broad base: legume subsessile. 



Same range as the preceding, but far more abundant; never 

 intergrading or hybridizing with it, hence not a small-flowered 

 variety, but specifically distinct. Possessed of more vitality 

 than the last, it is often found on higher ground and in 

 poorer soil. 



Trifolidm VIRE8CENS. Near the two preceding, but slender

 of the leaves: heads less than an inch broad, 9 to lo-flowered: 

 flower? or 8 lines long, greenish; calyx-teeth all slender y 

 subulate, the two upper shorter than the tube and eosely 

 approximate, the lower about twice the length of the tube.
