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

 winged. — Near Salina, N. Y. (^Fry)\ also Cal. (Eu.) 



2. SPERGULA L. Spurrey 



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. ARVExsis L. (CoRx 8.) Annual, bright green., scarcely or not at all 

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

3. SAGINA L. Pearlwort 



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 stems 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. decumbens. 

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

1. S. deciimbens (EU.) 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 o 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. Smithii (Gray) ^Yats., a slender form, apetal- 

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

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



2. S. procumbens L. Annual 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, 

 sometimes none. — Springy places and damp rocks, chiefly near the coast, Nfd. 

 to Pa. and Del.; also Ont. and Mich. (Eu.) 



3. S. nodbsa (L.) Fenzl. Tufted perennial, erect, glabrous; upper leaves

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