abovo ill age) : authors huiceolute or linear (yellow or violet), introrae, more or less 

 connivont around the filifonn exserted style. Stigma small. Capsule ovoid or ob- 

 long, splitting from the apex into 5 or more teeth or valves : placenta columnar, 

 many seeded. — Perennial smooth herbs, acaulescent ; with a tuft of membranaceous 

 leaves, and below fibrous roots springing from a short erect crown, sending up a 

 naked simple scape, which is terminated by an umbel of few or many (rarely even 

 solitary) handsome llowci's: these at lirst gracefully pendulous on the recurved sum- 

 mit of the pedicels : after llowering the pedicels are erect. Involucre of a few 

 slender bracts. Corolla purple, pink, or sometimes white. The Howers occasionally 

 vary with all their parts in fours. 



1. D. A^eadia, Linn. Leaves varying from obovate to lanceolate, entire or 

 more or less toothed: scape 3 to 15 inches high: umbel 2 - 20-llowcred. — So far 

 as we can make out, only one species occurs, which extends across the continent, 

 and on the Pacilic side tlirough fully 40 degrees of latitude (viz. from Guadalupe 

 Island, Lower California, to those within Bohring Straits), varying imiu(!usely and 

 inextricably. The Pacific forms (which usually have rather shorter or blunter 

 anthers tliau the Atlantic) may, as to their leading features, bo mainly but loosely 

 arranged under the following varieties. 



Var. brevifolium : common through the wanner ])arts of tlie State: leaves 

 round-obovato or spatulate, one half to an incli and a half long, sbort-pctioled, tliick- 

 ish : scape a span to near a foot high, few - manyllowfired : capsule ovoid, hardly 

 exceeding the minutely glandular calyx. — D. eUipticnm, Nutt. ex Durand, PI. 

 Pratt, in Jour. Acad. Pliilad. n. ser. ii. 95. D. intcgri folium, lientli. PI. llartw. 

 322, not of Michx. 



Var. lancifolium: common in wet mountain meadows, llowering in summer: 

 leaves oblanceolate or lanceolate-s{)atulate, 3 to 10 inclies long (including the short 

 margined petiole), quite entire, mucronate : pedicels and culyx commonly minutely 

 glandular ; the lanceolate or triangular-lanceolate lob;\s of the latter nearly equalling 

 the short-ovoid capsule. — D. Jajf'raifi of the gardens. 



Var. alpinum: a diminutive state of the foregoing, on the higher mountains, 

 at 9,500 to 12,000 feet : the narrow loaves an inch or two, the 1 - 3-nowcre(l scape 

 2 to 4 inchoa high : pedicels and calyx quite glabrous. 



Var. macrocarpum : a mostly largo and stout form, from yVlaska soutlnvard : 

 spatulate or oblanceolate leaves 5 to 10 inches long (including the petiole) : scapes 

 often a foot high, several - many-flowered : capsule oblong or almost fusiform (half to 

 three fourths of an inch in length), about twice the length of the narrow calyx- 

 lobes. — A form which may be referred hero, with laciniatcly-tootlied spatulate 

 loaves, was collected on the mountains of Ventura Co., Bremer. 



Var. frigidum, Hook. Bot. Mag. t. 5871, k S. Watson, Bot. King Exp. : in- 

 cludes various forms, ranging from the high Sierra northward to the islands within 

 Behring Straits : leaves obovate or oblong, very obtuse, mostly entire, with either 

 short or slender petiole: scape a span or more high, few -several-flowered : calyx- 

 lobes longer than the tube, varying from broadly to ovate-lanceolate, shorter than 

 the oblong (or sometimes ovoid ?) cajisule. — D. frigidum, Cham. & Schlecht. ; Seem. 

 Bot. Herald, t. 9. 



Var. latilobum: leaves thin, oval, undulate-toothed, 1 to 2^ inches long, ab- 

 ruptly contracted into a petiole of nearly twice the length : scape a span to a foot 

 high, 1 -flovoral-flowenvl ; calyx-lolx^s ovate or triangular-ovate, ni)t longer than the 

 tube,, about half the length of the narrowly oblong capsule. — I). }fe.a(lia, var. fri- 

 gidum, Watson, 1. c, in jiart. (Kast side of Cascade ^Its., AVa-shington Territory,
