b. Seeds distinctly rugose-roughened under a lens. 



S. GRAMINEA, L. Stems ascending, smooth and shining, 1— 2i feet 

 high, sharply 4-augled (rhombic in cross-section) ; internodes usually 

 elongated : leaves lanceolate or lance-linear, thickish, attenuate, fur- 

 rowed above and with midrib prominent beneath : inflorescence a 

 broad terminal pedunculate cyme, often accompanied by one or two 

 smaller cymes springing at its base ; pedicels elongated, spreading, or 

 deflexed: capsule exceeding the calyx. — Spec. 422; Eng. Bot. xii. 

 t. 803 ; Fenzl in Ledeb. Fl. Ross. i. 391 ; Wats. & Coulter in Gray, 

 Man. ed. 6, 87. — Introduced in moist grassy places, Nova Scotia to 

 New Jersey, and in Northern States across the continent ; common. 

 (Europe.) 



S. uliginosa, Murr. Low, weak, diffuse: stems numerous, 

 leafy : leaves lanceolate or elliptic-lanceolate, 6-8 lines long, acute at 

 each end : inflorescences few-flowered, pedunculate or sub-sessile, 

 much smaller than in the last, becoming decidedly lateral, 1^ inches 

 or less in length : flowers smaller and petals relatively shorter than in 

 the related species: sepals very acute, If lines in length. — Comm.

•w- ++ Bracts foliaceous (except in S. borealis, var. corollina.) 

 = Leaves narrowly elliptical to lanceolate or linear. 



S. longipes, Goldie, may be sought here, as weak specimens 

 with solitary terminal long-peduncled flowers do not always show the 

 scarious bracts which are developed in more vigorous plants. 



S. borealis, Bigel. Suberect, 6-10 inches in height, smooth or 

 nearly so: leaves lanceolate, attenuate, 6-18 lines long, with one 

 prominent nerve: pedicels scattered, 8-14 lines in length, often 

 deflexed : sepals ovate-lanceolate, scarious-margined, acute or often 

 narrowed to an obtusish apex : petals much shorter than the calyx or 

 none: capsule narrowly ovoid, acutish, 11-2 times as long as the 

 sepals; seeds smooth. — Fl. Bost. ed. 2, 182; Torr. & Gray, Fl. i.
