Vol. II. 



Lysimachia prodflcta (A. Gray) Fernald [L. foliosa Small] has characters intermediate be- 

 tween this species and the following, the flowers in leafy-bracted racemes, the leaves opposite or 

 whorled, and may be a hybrid between them. 



4. Lysimachia terrestris (L.) B.S.P. Bulb- 

 bearing Loosestrife. Fig. 3290. 



Viscum terrestre L. Sp. PI. 1023. 1753. 

 Lysimachia striata Ait. Hort. Kew. I: 199. 1789. 

 L. terrestris B.S.P. Prel. Cat. N. Y. 34. 1888. 



Glabrous; stem erect, simple or branched, 8'-2° 

 high, often bearing, after flowering, long bulblets 

 (suppressed branches) in the axils. Leaves oppo- 

 site or some of them rarely alternate, lanceolate 

 or oblong-lanceolate, acute or acuminate at both 

 ends, short-petioled, or sessile, usually black- 

 punctate, 1-3' long, 2"-8" wide; flowers 3"-$" 

 broad, in terminal bracted mostly elongated 

 racemes ; or some of them solitary or 2-3 together 

 in the upper axils ; pedicels slender or fiHf orm, 

 S"-9" long; sepals ovate or lanceolate, acute; 

 corolla rotate, deeply parted, yellow with purple 

 streaks or dots; filaments monadelphous below, 

 glandular; capsule about I J" in diameter, nearly 

 as long as sepals. 



In swamps and moist thickets, Newfoundland and Manitoba, south to Georgia and Arkansas. 

 The plant sometimes produces no flowers, but bears bulblets freely in the axils in the autumn, and 

 in this condition was mistaken by Linnaeus for a terrestrial mistletoe. Swamp-candles, July— Sept. 



5. Lysimachia Nummularia L. Money- 

 wort. Creeping Loosestrife. Fig. 3291. 



Lysimachia Nummularia L. Sp. PI. 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, i'-i' long, sparingly black-punctate; 

 flowers solitary in the axils, 8"-i2" broad; sepals 

 cordate-ovate to lanceolate, acute, half as long 

 as the rotate deeply 5-lobed yellow and dark- 

 dotted corolla; filaments glandular, monadel- 

 phous at the base; capsule shorter than the 

 sepals. 



In moist places, Newfoundland to New Jersey, 

 Virginia, Illinois and Michigan Naturalized from 

 Europe. June-Aug. Lower leaves sometimes nar- 

 rowed at the base. Creeping or wandering Jenny 01 

 Sally. Herb-twopence. Two-penny grass. Down-hill- 

 of-life. 



6. STEIRONEMA Raf. Ann. Gen. Phys. 7: i92T~i820. 



Perennial leafy herbs, with opposite or verticillate simple entire leaves, and axillary 

 slender-peduncled nodding or spreading yellow flowers. Calyx S-parted, persistent, the seg- 

 ments valvate in the bud. Corolla rotate, deeply 5-parted, with no proper tube, the lobes 

 cuspidate or erose-denticulate, each separately involute or convolute around its stamen. 

 Stamens 5; filaments distinct, or united into a ring at the very base, granulose-glandular; 

 anthers linear, becoming curved ; staminodia S, subulate, alternate with the stamens. Ovary 

 globose; ovules few or numerous. Capsule S-valved, several-matiy-seeded. Seeds margined 

 or angled. [Greek, sterile threads, from the abortive stamens.] 



About five species, natives of North America. Type species: Steironema ciliatum (L.) Raf. 

 Leaves membranous, pinnately veined. 

 Leaves ovate or ovate-lanceolate. 

 Stem erect; flowers 6"-i2" broad. 



Petioles strongly ciliate ; capsule longer than the calyx. i. .S. ciliatum. 



Petioles not ciliate, or slightly so at base ; capsule not longer than calyx. 



2, S, intermedium. 

 Stem reclined ; flowers i"-a," broad ; leaves not ciliate ; petioles naked 3. .?. radicans. 



Leaves lanceolate, oblong or linear ; stem erect. 4. 5". lanceolafum. 



Leaves firm, linear, i-nerved, the lateral veins obscure. 5. 5. quadriflorum.
