LILIACEJE. (LILT FAMILY.) 525 



2. Z. glatlCUS, Nutt. Stem l-3 high from a coated bulb; leaves flat; 

 panicle rather simple and few-flowered ; base of the perianth coherent with the base 

 of the ovary, the thin ovate or obovate sepals marked with a large obcordate 

 gland. (Anticlea glauca, Kunth.) Along the St. Lawrence and Great Lakes 

 (Bergen Swamp, Gennesee Co., New York, G. T. Fish) to N. Illinois : rare. 



# * Glands of the perianth obscure. (Here also Amianthium Nuttallii, Gray.) 



3. Z. leimanthoides. Stem 1- 4 high from a somewhat bulbous base, 

 slender ; leaves narrowly linear ; flowers small (4" in diameter) and numerous, 

 in a few crowded panicled racemes ; only a yellowish spot on the contracted base 

 of the divisions of the free perianth. (Amianthium leimanthoides, Gray.) 

 Low grounds, pine barrens of New Jersey (Durand, Knicskern) and southward. 



5. STENANTHIUM, Gray (under Veratrum). 



Flowers polygamous. .Perianth spreading; the sepals narrowly lanceolate, 

 tapering to a point from the broader base, where they are united and coherent 

 with the base of the ovary, not gland-bearing, persistent, much longer than the 

 short stamens. Anthers, pods, &c. nearly as in Nos. 4 and 6. Seeds nearly 

 wingless. Smooth, with a wand-like leafy stem from a somewhat bulbous base, 

 long and grass-like conduplicate-keeled leaves, and numerous small flowers in 

 compound racemes, forming a long terminal panicle; in summer. (Name com- 

 posed of 0Tfi>oy, narrow, and av6os,flmver, from the slender sepals and panicles.) 



1. S. angustifblium, Gray. Leaves linear, elongated ; flowers (' long), 

 white, very short-pedicelled, in slender racemes ; the prolonged terminal one, 

 and often some of the lateral, fertile. (Veratrum angustifolium, Pursh. He- 

 lonias graminea, Bot. Mag.} Low prairies and meadows, Penn. to Illinois and 

 southward towards the mountains. Stem slender, 2 -6 high. 



6. VERATRUM, Tourn. FALSE HELLEBORE. 



Flowers monoeciously polygamous. Perianth of 6 spreading and separate 

 obovate-oblong (greenish or brownish) sepals, more or less contracted at the 

 base, entirely free from the ovary, not gland-bearing. Filaments free from the 

 sepals and shorter than they, recurving. Anthers, pistils, fruit, &c. nearly as 

 in Melanthium. Somewhat pubescent perennials, with simple stems from a 

 thickened base producing coarse fibrous roots (very poisonous), 3-ranked leaves, 

 and racemed-panicled dull or dingy flowers; in summer. (Name formed of 

 vere, truly, and ater, black.) 



1. V. viride, Ait. (AMERICAN WHITE HELLEBORE. INDIAN POKE.) 

 Stem stout, very leafy to the top (2 -4 high); leaves broadly oval, pointed, 

 sheath clasping, strongly plaited; panicle pyramidal, the dense spike-like racemes 

 spreading ; perianth yellowish-green, moderately spreading. Swamps and low 

 grounds: common. (Much too near V. album of Europe.) 



2. V. parvifldrum, Michx. Stem slender (2 -5 high), sparingly leafy 

 below, naked above; leaves scarcely plaited, glabrous, contracted into sheathing peti- 

 oles, varying from oval to lanceolate ; panicle very long and loose, the terminal 

 raceme wand-like, the lateral slender and spreading ; pedicels as long as the flow-
