2. Petals bifid ; each segment with or without a smaller lateral tooth. 

 1* Low, 3-8 inches in height. 



S. Grayii, Wats. — Cespitose, minutely pubescent and glandular : 

 rootstock elongated, much branched: stem simple, erect, 4-6 inches liigh, 

 l_5.flovvered ; leaves short, oblanceolate or spatulate, slightly fleshy, 

 4-8 lines in length, the radical numerous, crowded ; the cauline about 

 3 pairs : calyx broadly cylindrical : the teeth rounded ; petals pink, 

 with blade deeply bifid, and segments each bearing a lateral tooth ; 

 claw narrowly auricled : capsule short ovoid, scarcely stiped. — Proc. 

 Am. Acad. xiv. 291 ; Robinson, Bot. Gaz. xvi. 44, t. 6. — Mt. Shasta 

 above the timber line and near snow, Brewer, Hooker ^ Gray, Pack- 

 ard, Pringle. Specimens collected on Mt. Rainier by E. C. /Smith, 

 and having somewhat longer leaves, may be doubtfully referred to this 

 species. 



S. Watsoni. Finely glandular above, minutely pubescent, nearly 

 smooth below : stems many, cespitose from a multicipital caudex, 

 erect, very slender, simple, 4-8 inches in height, bearing 1-3 (rarely 5) 

 flowers : leaves linear or very narrowly oblanceolate, acute, dark 

 green ; the radical numerous, an inch in length, seldom exceeding a 

 line in breadth : the slender petioles expanding at the base, closely 

 imbricated and connate by scarious membranes : calyx ovate or some- 

 what obovate, 5-6 lines in length, with purple more or less anastomos- 

 ing nerves ; the teeth with membranous margins : petals white or 

 rose-colored : the blade short, a line in length, bifid ; each segment 

 usually bearing a short lateral tooth ; appendages obtuse : styles ordi- 

 narily 3, rarely 4. — Lychnis Californica, Wats. Proc. Am. Acad, 

 xii. 248. — California, near Ebbett's Pass, Brewer ; Mt. Dana, 

 Bolander ; Sierra and Plumas Cos., Lemmon. As in S. LyalUi, the 

 anthers are often infested by Ustilago antherarum, and in consequence 

 enlarge and turn purple. 



S. Suksdorfii, Robinson. Low, densely matted, alpine : stems 

 2-3 (rarely 4-5) inches high, simple 1-3-flowered, minutely pubes- 

 cent below, glandular above : stem leaves about 2 pairs, linear, 3-7 

 lines long, a line wide ; radical leaves numerous, crowded, similar or 

 somewhat spatulate : calyx broadly cylindric or campanulate, seldom 

 exceeding 5 lines in length ; nerves conspicuous, simple below, anas- 

 tomosing above: petals white, little exceeding the calyx, shallowly 

 bifid; lobes entire; appendages oblong, refuse: stipe of capsule 1^ 

 lines long. — Bot. Gaz. xvi. 44, t. 6. — California to Washington, 

 Mt. Stanford, Hooker 8^ Gray; Mt. Paddo, Suksdorf; Mt. Hood.
