* * * fleshy biennial with a thick root. 



4. S. mSdia (L.) C. Presl. Stout root perpendicular; stems spreading; 

 flowers large ; pods at length 7 min. long, exceeding the calyx ; seeds mostly 

 winged. Near Saliua, N. Y. (Fry); also Cal. (Eu.) 



2. SPERGULA L. SPURRET 



Stamens 5 or 10. Styles 5. The 5 valves of the pod opposite the sepals. Em- 

 bryo spirally annular. Leaves in whorls. Otherwise as Spergularia. (Name 

 from spargere, to scatter, from the seeds. ) 



1. S. AKVENSIS L. (CORN S. ) Annual, bright green, scarcely or not at all 

 viscid ; leaves numerous, in whorls, thread-shaped (2-5 cm. long) ; stipules

 scented ; seeds margined, obscurely dotted, not papillate. Sparingly adventive 

 in fields, Ct. (Graves) and Vt. (Jones) to Ont. (Fletcher). 



3. SAGtNA L. PKARLWORT 



Sepals 4 or 5. Petals 4 or 5, undivided, or often none. Stamens as many as 

 the sepals, rarely twice as many. Styles as many as the sepals and alternate 

 with them. Pod many-seeded, 4-5-valved to the base ; valves opposite the se- 

 pals. Little matted herbs, with thread-like or awl-shaped leaves, no stipules, 

 and small flowers terminating the steins or branches ; in summer. (Name from 

 sagina, fattening ; previously applied to the Spurrey.) 



Upper leaves not proliferous ; petals not longer than the sepals. 



Seeds at maturity orange-brown, dotted with resinous atoms . . . 1. S. decumbeiui. 

 Seeds at maturity dark or grayish brown, smoothish or roughened but with- 

 out atoms '2. S. procumbent.

longer than the sepals 3. S. nodosa. 



1. S. decumbens (Ell.) T. & G. Annual, ascending; the peduncles and 

 calyx with the margins of the upper leaves at first glandular-pubescent; leaves 

 short, often bristle-tipped ; sepals and valves 5 or rarely 4 ; pod oblong-ovoid, 

 nearly twice longer than the calyx. -(S. apetala Am. auth., not Ard.) Mass, 

 to 111., Mo., and south w. Var. SMfxHii (Gray) Wats., a slender form, apetal- 

 ous, at least in the later flowers. In waste ground near Philadelphia, and in 

 sandy fields at Soraers Point, N. J. (C. E. Smith). 



2. S. procumbens L. Annnal or perennial, depressed or spreading on the 

 ground, glabrous ; leaves linear-thread-shaped ; apex of the peduncle often 

 hooked soon after flowering ; petals shorter than the broadly ovate obtuse sepals,

Sepals 5. Petals 5, entire, sometimes barely notched, rarely wanting. Sta-
