 in meadows or moist woods, sometimes in moist places at middle altitudes. B. C, 

 Idaho, Mont., and Alta. — Stems 0.3 to 1 meter high, rather slender; leaflets lance- 

 oblong, thin, bright green, 2 to 6 cm. long, sharply toothed; umbels long-stalked;

 at middle altitudes, in moist woods or thickets or along streams. B. C. to Oreg., 

 Wyo., and Alta.— Stems very stout, 0.5 to 1.5 meters high; petioles with very broad 

 sheathing bases; leaflets thick, ovate, coarsely toothed, 2 to 7 cm. long; fruit 4 to 6

A very showy plant, which blooms for a long time. In general appearance it is 

 much like Heracleum lanatum. The roots have a strong odor. 



13. LEPTOTAENIA Nutt. 



1. Leptotaenia multifida Nutt. Frequent on the east slope at low and middle 

 altitudes and sometimes near timber line, on open rocky slopes or in thickets. 

 B. C. to Calif., Colo., and Alta. — Stout perennial, 30 to 80 cm. high, with glabrous 

 stems; leaves finely puberulent, 10 to 30 cm. wide, divided into numerous leaflets,

 with a narrow corky wing around the edge. 



The plants bloom early in the season, and the leaves soon turn yellow. McClintock 

 gives the following uses of this plant among the Blackfoot Indians: The root was 

 used to prepare a hot drink, taken as a tonic by people in poor health, especially to 

 enable them to put on flesh; the pulverized roots were burned as incense; when 

 horses had the distemper they were made to inhale smoke from the burning plant, 

 the pulverized plant was mixed with brains and employed in tanning.
