Lysimachia. PRIMULACE.E. 11 



undernealh. Racemes ovate or capitate, about an inch long ; the peduncle villous, an inch 

 or more in length. Calyx 6-7- (rarely 5-) parted, spotted wiiii orange : segments linear- 

 lanceolate. Corolla yellow, deeply divided into 6 or 7 linear segments, which are often 

 scarcely at all spotted. Stamens 6 - 7, longer than the corolla : fdaments slender, smooth, 

 united into a very short tube at the base, the intermediate teeth very minute : anthers small, 

 ovate. Ovary globose-ovate, spotted : style slender, about as long as the stamens ? stigma 

 capitate. Capsule 5-valved, 5-seeded. 



Swamps, particularly where Sphagnum abounds ; not common. June. This agrees in all 

 essential characters with the European plant. Endlicher and Duby have revived the old 

 genus Naumbeugia, which was eslablished on this plant, but I think it is scarcely more than 

 a section of Lysimachia. The intermediate teeth or abortive stamens differ much indifferent 

 species, and in some they are wanting. 



3. TRIENTALIS. Linn. ; Endl gen. 4208. CBWKWEED WJNTERGREEN.

Calyx 6 - 8-parted, spreading. Corolla rotate, 6 - 8-parted. Stamens 6 - 8 : filaments 

 slender : anthers oblong or linear. Ovary globose : style filiform : stigma obtuse. Capsule 

 globose, somewhat fleshy, 5-valved ; the valves revolute and deciduous. Seeds few, with 

 a reticulate membranaceous testa. — Humble, smooth, perennial herbs, with entire ovate or

 Peduncles one-flowered, slender, arising from the bosom of the leaves.

Root (or rhizoma) creeping, throwing up simple erect slender stems about a span high. 

 Leaves in a terininal imperfect whorl, with 2-3 smaller or scale-like ones on the stem,

Low shady woods, and in sphagnous swamps. Fl. May. Fr. July.
