Scientific and applied pharmacognosy intended for the use of students in pharmacy, as a hand book for pharmacists, and as a reference book for food and drug analysts and pharmacologists . botanists Heloniasdioica, the name first given to it by Pursh. It was for some time alsoreferred to as Chamselirium carolinanum. The name now generallyapplied is the Linnsean name, Chamselirium luteum, which wasrestored by Gray in the 5th edition of his Manual. While to thosewho are acquainted with taxonomy this use of synonomy is intelligible 78 SCIENTIFIC AND APPLIED PHARMACOGNOSY yet it is apt to produce a certain amount of confusion by drug col-lectors, as the generic name Helonias is applied to the Swamp Pink, abeautiful bog plant occasionally rather abundant in certain localitiesfrom New York to Virginia. Chamoelirium Luteum is a perennial, dioecious herb having arather fleshy bitter rhizome, a number of basal leaves which varyfrom lanceolate to elliptical-spatulate and an herbaceous slenderstem from 3 to 5 dm. in length terminated by a spike-like raceme ofsmall white flowers. It grows in moist meadows and thicketsthroughout the eastern United States. The plant is quite readily. Fig. 28.—Several types of Helonias rhizome: A, oblique rhizome with stembase and two stem scars; B, upright rhizome showing new growth at top.(Moser, Amer. Jour. Pharm., 1917, 89, p. 191). distinguished from Helonias bullata, which produces a short uprightrhizome, very long elliptical-spatulate or oblanceolate leaves whichare crowded at the base and from the middle of which arises thebracteate scape usually not longer than the leaves and terminatedby a dense raceme of rather large, perfect purple flowers. The lattergrows in bogs and appears to be localized in its habitat. Description.—Rhizome upright, or oblique, nearly cylindricaland slightly tapering from to 3 cm. long, about 1 cm. in diameter;externally grayish-brown, annulate from scars of bud-scales, upperportion with leaf bases enclosing
