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

 with blades deeply bifid, the segments each bearing a lateral tooth ; claws narrowly auricled :, 

 capsule short-ovoid, scarcely stiped. — Robinson, Bot. Gaz. xvi. 44, t. 6. — Mt. Shasta, above 

 the timber line and near snow. Brewer, Hooker & Gray, Engelmann, Packard, Pringle ;

S. Suksdorfii, Robinson, 1. c. Low, densely matted, alpine: stems 2 to 3 (rarely 4 to 5) 

 inches high, simple, 1-3-flowered, minutely pubescent below, glandular above : cauline 

 leaves about 2 pairs, linear-spatulate, 3 to 7 lines long, a line wide, obtusish ; radical leaves

 seldom exceeding 5 Hues in length ; nerves conspicuous, simple below, anastomosing above : 

 petals white, little exceeding the calyx, shallowly bifid ; lobes entire ; appendages oblong, 

 retuse: stipe of capsule H lines long. — California to Washington, Mt. Stanford, Hooker 

 & Gray; Mt. Paddo, Sitksdorf; Mt. Hood, Howell; Mt. Stewart, Brandegee; Mt. Rainier, 

 Piper. 



S. ^Watsoni, Robinson. Finely glandular above, minutely pubescent or nearly smooth be- 

 low: stems many, cespitose from a multicipital caudex, erect, very slender, simple, 4 to 10 

 inches in height, bearing 1 to 5 or more flowers : leaves narrowly 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 con- 

 nate by scarious membranes : calyx ovate or somewhat obovate, 5 to 6 lines in length, with 

 purple more or less anastomosing nerves; teeth with membranous margins: petals white or 

 rose-colored; blades short, a line in leugth, bifid; each segment usually bearing a short 

 lateral tooth ; appendages obtuse : styles ordinarily 3, rarely 4. — Proc. Am. Acad, xxviii. 

 143. Lychnis Californica, Wats. Proc. Am. Acad. xii. 248 ; Coville, Contrib. U. S. Nat. 

 Herb. iv. 70. L. Parryi, Wats. 1. c., of W. Wyoming, is apparently this species, although 

 the single specimen on which it was based is 4-5-carpelled. In the absence of other differ- 

 ences its separation on this (probably inconstant) character is highly artificial. — California, 

 near Ebbett's Pass, Brewer ; Mt. Dana, Bui under ; Sierra and Plumas Cos., Lemmon, south- 

 ward to Mineral King, ace. to Coville, 1. c. ; and northward to the Siskiyou and Cascade 

 Mts., Oregon, Howell, and Washington, Piper. The anthers are often infested by Ustilago 

 antherarum, and in consequence enlarge and turn purple. 



O O Taller. 



S. Douglasii, Hook. Finely pubescent, scarcely viscid : stems very slender, usually de- 

 cumbent and geniculate at the base : leaves remote, long, linear to narrowly lance-linear,
