 nal) solitary, 1-flowered. 



/?. upper leaves reduced to bracts (not scarious) ; cyme spreading. 



In wet shady swamps, New-York ! from about lat. 42^ to Arctic America J 

 June-July. — ® {U '?) Stem 4-15 inches high, weak. Leaves an inch or 

 more long, 1-nerved, but with no lateral veins. Flower at first terminal, on 

 a filiform pedicel, becoming axillary by the evolution of a branch from the 

 axil of each of the upper leaves ; branches dichotomous in like manner : 

 flowers more commonly apetalous. Later in the season the lateral branches- 

 are also often floriferous, producing the ordinary dichotomous cymes ; and 

 then the flowers bear manifest petals. Stamens and petals distinctly perigy- 

 nous. Seeds smooth. — Certainly very distinct from S. longifolia, and much, 

 more closely allied to the succeeding species. 



15. S. aquatica (PoUich) : weak and decumbent, nearly glabrous ; leaves 

 oblong, acute, veined; petals 2-cleft, rather shorter than the lanceolate very 

 acute 3-nerved sepals ; capsule ovoid, about as long as the calyx ; styles 3. —

Sv/ampy springs, Chester County, Pennsylvania, Dr. Darlington ! Near 

 Philadelphia, Dr. Pickering! Rocky Mountains, Hooker. Unalaschka, 

 Chamisso. May.— If Stem 6-12 inches long, very slender. Leaves 

 about i an inch long; veins very manifest under a glass. Flowers smaller 

 than in S. borealis. Seeds minutely tuberculate. — The inflorescence con- 

 sists of the ordinary central 1-floAvered ebracteolate peduncle, and two lateral 

 few-flowered peduncles evolved somewhat later ; and the stem is continued 

 by a fourth or adventitious branch, which throwing the inflorescence on one 

 side, appears like the main stem. — The character and description here given 

 are drawn from specimens collected by Dr. Darlington, which, as that excel- 

 lent botanist remarks, agree minutely with the European species to which 

 they are here referred. The shorter leaves and capsules, the tuberculate 

 seeds, and especiaOy the inflorescence, clearly distinguish the plant from S. 

 borealis. 



16. ,S. crispa (Cham. & Schlecht.) : glabrous; stems diffuse, decumbent ; 

 leaves veiny, ovate, abruptly acute or acuminate r.t each end, the margin un- 

 dulate ; flowers axillary, solitary on short peduncles hardly longer than the 

 leaves ; petals mostly wanting, oi 2-parted and very much shorter than the 

 lanceolate 3-nerved sepals.— CAa???. ^ Schlecht. in Linncea, I. p. 51 ; Bong,

tJnalaschka, Chamisso; Sitcha, Bongard ; Oregon, jiear Fort Van- 

 couver, in deep pine-woods, Nnttall .'— U Stems nearly simple. Leaves 

 much shorter than the internodes, i an inch or less in length, often obtuse or 

 subcordate at the base, with a central and an intramarginal nerve, the inter- 

 vening space beautifully reticulated. Capsule about the length of the calyx. 

 Seeds smooth. 



17. S. calycanlha (Bongard): csespitose ; stems decumbent, flaccid: 

 leaves ovate-lanceolate, connate, the margin minutely ciliate with white 

 hairs, much shorter than the internodes ; cyme dichotomous; peduncles fili- 

 form; petals none; sepals ovate-lanceolate, 3-nerved, a little shorter than the 

 obtuse subglobose capsule. Bong. veg. Sitcha, I. c. p. 127. — Arenaria
