Bulbous herbs, with simple leafy stems, and large erect or drooping 
showy flowers. Flowers funnelform or campanulate; the segments 6, 
separate, spreading or recurved, deciduous, each with a nectar-bearing 
groove inside next the base. Stamens 6, usually shorter than the seg- 
ments, hypogyncus, slightly attached to the segments; filaments slender 
or subulate; anthers linear, versatile, the sacs longitudinally dehiscent. 
Ovary 3-celled; ovules many; style long, slightly club-shaped above; 
stigma 3-lobed. Capsule obovoid or oblong, loculicidally dehiscent. 
Seeds many, flat, arranged horizontally in two rows in each cavity. 
Flower or flowers erect ; perianth-segments narrowed into long claws. 
Leaves narrowly lanceolate or linear, mostly alternate. 1. L. lanccolatum. 
Flowers drooping or spreading ; perianth-segments not clawed. 
Leaves mostly verticillate, native species. 
Leaves finely roughened on the veins beneath. 2. L. canadense. 
Leaves perfectly smooth. 3. L. siipcrhum. 
Leaves alternate, the axils bulbiferous, garden escapes. 4. L. tigrinum. 
1. Dillium lanceolatum new species. 
Bulb varying from one-half an inch to an inch in diameter, made up of 
flattish scales; stem 10 — 30 inches high, slender, frequently somewhat 
glaucous; leaves sessile, narrowly lanceolate to nearly linear, alternate or 
scattered, a few of the upper verticillate, tapering both ways, apex 
bluntish, margins smooth, usually 2 — 3 inches long and 2 — 4 lines wide; 
flowers usually solitary or two or three and of a reddish orange color, 
peduncled; perianth-segments ovate, spotted below, long-clawed; stamens 
included, filaments slender; style exceeding the stamens but shorter than 
the perianth-segments; capsule about two inches long, oblong in outline. 
The type specimen w’as collected in Decatur county, June 7, 1896. The 
species grows in rather dry prairie soil, being solitary, but rather fre- 
quent in occurrence. Strange as it may appear this species has passed
