The Gillenia stipulacez only differs in having 
stipules and smaller roots, and is known as Bow- 
man’s root. Gillenia received its name from 
Gillanius, a European botanist. The plant is 
perennial and native of the United States, and 
sends up quite'a number of stems from the same 
root, attaining a height of 3 feet (1 meter) or 
more, having ternate leaves with short leaflets, 
ovate, lanceolate, with serrated edges. The 
flowers grow in panicles and are of a pale-rose 
color, with five petals, many stamens, five pis-

and about % inch (12 millimeters) thick. Ex- 
ternally of a dark-brown color; when broken the 
fracture is abrupt and presents a red or pinhish 
hue, and by the aid of a magnifying glass shows 
many resin dots. Gillenia contains starch, tan-

lenin, which is a light-gray, amorphous powder 
colored red by nitric acid. The gillenia is mildly 
emetic in its action, occasionally acting as a
