CARYOPHYLLE^. 123 



uudulate-crisped : ti.. solitary in the axils, or few in a cyme : sepals 

 ovate-lanceolate ; the petals not equalling them : capsule ovate-oblong, 

 little exserted : seeds smoothish. — From the Calaveras Big Trees, Hooker 

 lO Gray, to Auburn, 3[iss Harrison, and northward to Alaska. 



7. S. Jamesii, Torr. in Ann. Lye. N. Y. ii. 169 (1827). Erect and 

 rather stout, }4 — 1 ft. high ; herbage deep dull green, pubescent and 

 very viscid : leaves lanceolate, acuminate, 1 ~3 in. long : cyme leafy, 

 rather contracted, the branches short and divaricate : sepals oblong, 

 acute, 2 —3 lines long, shorter than the 2-parted petals : capsule ovate, 

 shorter than the calyx : seed smooth. — Dry pine woods of the middle 

 Sierra, from Kern Co., Greene, northward. 



8. S. littoralis, Torr. Pac. R. Rep. iv. 69 (1857). Pubescent, ascend- 

 ing, stoutish, 1 ft. high : leaves 1 in. long, ovate, acute, rounded at base, 

 rather thick : .fl. in a terminal compound cyme : sepals lanceolate, acute, 

 3 lines long, obscurely 3-nerved, shorter than the 2-parted petals : 

 capsule included within the calyx. — At Point Reyes, near the seashore, 

 Bigeloiv. 



7. ARENARIA, Chabrxus (Sandwoet). Mostly low tufted herbs 

 with sessile usually subulate often rigid leaves and no stipules ; flowers 

 white, cymose-panicled or capitate-clustered. Sepals 5 or 4. Petals as 

 many, entire, emarginate, or 0. Styles 3, opposite as many sepals. 

 Capsule globose or ovoid, dehiscent into as many entire, 2-cleft, or 

 2-parted valves as there are styles. Seed reniform-globose, or laterally 

 compressed. 



* Cespiiose perennials with scarious-bracted inflorescence ; valves of the cap- 

 sule 3, clefl. or parted ; seeds not carunculate. — Arenaria proper. 



1. A. cougesta, Nutt. in T. & G. Fl. i. 178 (1838). Brewerina suffru- 

 tescens. Gray, Proc. Am. Acad. viii. 620 (1873). Glabrous, 6—10 in. high, 

 from a cespitose and suffrutescent base : leaves linear-subulate, scabrous 

 on the margin, rigid and somewhat pungent, those of the low sterile 

 shoots 1— 2io in. long, of the stem ^2—1 in. long, spreading or suberect : 

 fl. subsessile in several capitate-congested terminal fascicles, or pedicelled 

 and subumbellate : sepals ovate-oblong, scarious-margined, obscurely 

 3-nerved, 1%~1% lines long, acute : petals narrowly oblong, 3 — 4 lines : 

 stigmas capitellate : capsule coriaceous, about equalling the calyx : 

 seeds small, angular.— In the higher Sierra from near Donner Lake 

 northward ; the flowers less crowded than in Nuttall's type from the 

 northern Rocky Mt. region, the herbage less glaucous, etc. The capitel- 

 late character of the stigmas is exceptional in this family ; and on this 

 Dr. Gray at one time held the plant to be of a distinct generic type ; a 

 view afterwards relinquished. 



2. A. capillaris, Poir. Encycl. vi. 380 (1804) : A. nardlfolia, Ledeb.
