(Fig. 2815.) 
Lysimachia Nummularia I. Sp. Pl. 148. 1753. 
Glabrous; stems creeping, sometimes 2° long, 
often rooting at the nodes. Leaves opposite, 
orbicular or broadly oval, obtuse at both ends 
or truncate or cordate at the base, manifestly 
petioled, %4’-1/ long, sparingly black-punctate; 
flowers solitary in the axils, 8//-12/” broad; 
sepals cordate-ovate to lanceolate, acute, half as 
long as the rotate deeply 5-lobed yellow and 
dark-dotted corolla; filaments glandular, mon- 
adelphous at the base; capsule shorter than 
the sepals. 
In moist places, Newfoundland to New Jer- 
sey, Pennsylvaniaand Indiana. Naturalized from 
Europe. June-Aug. Lower leaves sometimes

6. STEIRONEMA Raf. Ann. Gen. Phys. 7: 192. 1820. 
Perennial leafy herbs, with opposite or verticillate simple entire leaves, and axillary 
slender-peduncled nodding or spreading yellow flowers. Calyx 5-parted, persistent, the 
segments valvate in the bud. Corolla rotate, deeply 5-parted, with no proper tube, the lobes 
cuspidate or erose-denticulate, each separately involute or conyolute around its stamen. 
Stamens 5; filaments distinct, or united into a ring at the very base, granulose-glandular; 
anthers linear, becoming curved; staminodia 5, subulate, alternate with the stamens. 
Ovary globose; ovules few or numerous. Capsule 5-valved, several-many-seeded. Seeds 
margined or angled. [Greek, sterile threads, from the abortive stamens. ] 
About five species, natives of North America. 
Leaves membranous, pinnately veined. 
Leaves ovate or ovate-lanceolate. 
Stem erect; flowers 6'/-12'' broad. 
Petioles strongly ciliate; capsule longer than the calyx. 1. S. czliatum. 
Petioles not ciliate, or slightly so at base; capsule not longer than the calyx. 
2. S. tonsum. 
Stem reclined; flowers 3'’-4’’ broad; leaves not ciliate; petioles naked. 3. S. radicans. 
Leaves lanceolate, oblong or linear; stem erect. 4. S. lanceolatum.

Stems erect, simple or branched, slender, 
mostly glabrous, 1°-4° high. Ieaves membra-

petioles ciliate, 4% ’—%’ long; peduncles filiform,
