 Marrcbicm-like Leoxurus. 



Root perennial. Stem 2 to 4 feet high, with ascending branches, clothed with a 

 short retrorse cinereous pubescence. Leaves 2 to 3 inches long, and halt an inch

 mucronate, petioles 1 to 2 inches long ; upper or floral leaves lanceolate, sparingly 

 incised-dentate, the smaller ones often entire, on short slender petioles. Yerticih 

 many -flowered, subsessile, dense, distant, forming interrupted leafy spikes6to 18

Obs. This foreigner has probably escaped from the Botanic Garden of the late 

 Humphrey Marshall, and bids fair to become extensively naturalized in the 

 surrounding country. There arc no native species in the U. States.
