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

 delta of the Mackenzie, Mixx E. Tuijlor, July, 1892. A fragmentary sj)ecinieii from tlie 

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

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

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

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

 of the more or less distinctly auricled claws ; appendages oblong. — Vahl in P>ies, Maut.

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

 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 liigh : leaves linear, I to U inches in length: calyx green- or rarely purple-nerved, 

 5 to 6 lines long ; teeth short, scarcely acute : petals narrow, about etpialling 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. —

Li. 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, e.xcl. Wyoming plant. L. 

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

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

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

 ex.serted petals, the material at hand fails to sliow 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, almo.st globose : flowers commonly penduloias in 

 anthesis : seeds margined : stems l-flowered except in var elatior. 



Li. apetala, L. More or less viscid-pubescent : stems 2 to 6 inches higli : 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.frir/ida, Schrank, Pflanz. Lab. 25. L. montana,

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

 Rocky Mts. to Montana, Canhy, 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.

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

 giu 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. mncropetat a, so far as the American specimens are concerned. — Kodiak Isl. 

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



* * Species of the Old World adventive in the Eastern and Middle States and in C'aniida: 

 corolla much exserted.
