226 CARYOPHYLLACEiE. Lychnis. 



than the slender narrowly auricled claws ; appendages lance-oblong. — Peel's Riv., at the 

 delta of the Mackenzie, Miss E. Taylor, July, 1892. A fragmentary specimen from the 

 Kowak Riv., N. Alaska, McLenegan, may be doubtfully referred to this species. 



L. affinis, Vahl. Glandular-pubescent, 3 to 6 inches high : leaves oblanceolate-linear, 9 

 lines to 3 inches in length : calyx ovate-elliptic, usually contracted at the mouth : petals 

 white or pink ; blades narrow, entire or retuse, narrowed from near the end to the summit 

 of the more or less distiuctly auricled claws; appendages oblong. — Vahl in Fries, Mant.

 to Labrador, at Rama, Sornborger. (N. Eu., Siberia.) Warming (Videusk. Selsk. Forhand. 

 1886, 129) states that in Norway the flowers are of two kinds, perfect and pistillate, and that 

 the petals in the latter are devoid of appendages and auricles. 



= = Rocky Mountain and western alpine species. 



L. montana, Watson. Glandular-pubescent : root thickish, subsimple : stems erect, 2 to 4 

 inches high : leaves linear, 1 to 1| inches in length : calyx green- or rarely purple-nerved, 

 5 to 6 lines long ; teeth short, scarcely acute : petals narrow, about equalling or a line or 

 two exceeding the calyx ; blades small, bifid ; claws narrow, one half to three fourths line 

 in breadth ; appendages small or absent : filaments naked : capsule sessile or nearly so. —

 N. W. Wyoming, Parry. 



L. Kingii, Watson. Densely covered with a very short pubescence, somewhat glandular 

 above : stems slender, erect, 4 to 6 inches high, 1-2-flowered : leaves narrowly linear : blades 

 of the petals rather short and broad, emarginate ; claws with broad ciliated auricles ; appen- 

 dages oblong; filaments pubescent. — Proc. Am. Acad. xii. 247, excl. Wyoming plant. L. 

 Ajanensis ? Wats. Bot. King Exp. 37. — Peaks of the Uintas, N. Utah, Watson. Dr. Wat- 

 son (1. c.) states that this species can be readily distinguished from L. apetala, with which it 

 grows. Aside, however, from the position of the flower in anthesis and the longer slightly 

 exserted petals, the material at hand fails to show any definite distinctions. In view of the 

 considerable variation of L. apetala in Asia these differences are not very satisfactory. 



++ -H- ++ Calyx large, much inflated, almost globose : flowers commonly pendulous in 

 anthesis : seeds margined : stems 1 -flowered except in var elalior. 



Li. apetala, L. More or less viscid-pubescent : stems 2 to 6 inches high : flowers perfect or 

 pistillate, at first pendulous, but becoming erect in fruit : petals in the typical form included ; 

 blades short, bifid ; segments rather irregular, sometimes with a small lateral lobe ; claws 

 auricled. — Spec. i. 437 ; Fl. Dan. t. 806. L. frigida, Schrauk, Pflanz. Lab. 25. L. montana,

 Bot. Foren. Festskr. 1890, 251, f. 25, 26. Wahlbergella apetala, Fries, 1. c. — N. Greenland 

 and Grinnell Land to Labrador (ace. to Macoun) and Alaska, also southward along the 

 Rocky Mts. to Montana, Canby, and Uintas, N. Utah, Watson. A polymorphous species, 

 the forms of which have been elaborated by Regel, Bull. Soc. Nat. Mosc. xxxiv. pt. 2, 

 570-574. 



Var. glabra, Regel. Glabrous throughout, otherwise as in the type. — Regel, 1. c, 

 570, 572. — Rocky Mts. of Brit. America, Bourgean ; St. Paul's Isl., Alaska, Elliott; Schma- 

 gin Isl., Harrington. The Alaskan form differs from Bourgeau's plant, upon which the 

 variety was founded, in having much larger thinner leaves. 



Var. elatior, Regel (extended). Pubescent, taller, 6 to 12 inches in height : stems 

 commonly several-flowered : petals sometimes considerably exserted. — Regel, 1. c. 573, 

 including var. macropetala, so far as the American specimens are concerned. — Kodiak Isl. 

 and northward in Alaska to Kotzebue Sound, ace. to Regel.
