L. lucidus, Turcz. Stem strict, stout, 2 or 3 feet high, hirsute-pubescent or glabrate, 

 acutely angled above: leaves lanceolate and oblong-lanceolate (2 to 4 inches long), acute 

 or acuminate, very sharply and coarsely serrate with triangular-subulate ascending teeth, 

 sessile or nearly so by an obtuse or acute base, coarsely punctate : calyx-teeth attenuate, 

 subulate. (Siberia, Japan.)

 calyx-teeth less rigid. Bot. Calif, i. 592. L. obtusifulius, Benth. in DC. 1. c. ? Saskatche-

* * Not stoloniferous, but rootstocks more or less creeping: calyx-teeth 5, cuspidate or.spinulose-

L. EUROIVEUS, L., has less acutely angled stems, mostly broader and shorter subsessile leaves 

 with less unequal teeth or lobes, subulate-spinulose calyx-teeth, and rudiments of sterile 

 stamens obsolete or minute. Occurs as a ballast-weed at Norfolk and Philadelphia, Duruml,
