(n. 659). Mr. Gordon finds the same species on the upper 
sources of the Platte River. The roots are much branched 
and intricated, running under the soil and sending out sto- 
lones. The first leaflets of these stolones in a. are small and _ 
obcordate ; the rest linear-oblong or lanceolate, acute at both _ 
ends :—in £. the leaves are very broad, andthe plant assumes ——— 
much the character of T. repens: but the calyces are always — 
hairy, and the segments much — and narrower. _
