Lysimachia nummularia L.

Lysimachia nummularia plant

Family - Primulaceae

Stems - Repent, tp +40cm long (and sometimes much longer), herbaceous, multiple from the base, typically simple, with 4 wings from deccurent leaf tissue. Wings to .7mm broad, forming vertical grooves along the sides of the stems.

Lysimachia nummularia stem

Leaves - Opposite, petiolate. Petioles to +/-5mm long, glabrous, with a wide and shallow adaxial groove. Blades orbicular, to +/-2.5cm in diameter, glabrous, entire, somewhat cordate at the base, dark green above, lighter green below. Veins of the leaves impressed above, expressed below.

Lysimachia nummularia leaves

Inflorescence - Single axillary flowers. Peduncles to +/-2cm long, erect, glabrous.

Flowers - Petals typically 5 (sometimes 6), united at the very base and forming a small corolla tube. Tube to 1mm long. Free portion of petals glabrous, yellow, to +1.4cm long, 5-7mm broad, rounded at the apex, oblong-elliptic. Stamens 5(6), adnate at the base of the petals, erect, united at the base. Filaments yellow, broadest at the base and tapering to the apex, glandular puberulent, to 5mm long. Anthers yellow, to 2mm long. Ovary superior, green, glabrous, globose, 1.2mm in diameter. Style green, glabrous, 5mm long. Stigma small, purplish. Sepals 5(6), green, spreading, with the margins slightly revolute in the basal 1/2, ovate-lanceolate, acute to acuminate at the apex, to +/-7mm long, +/-5mm broad, glabrous.

Lysimachia nummularia flower

Lysimachia nummularia flower

Lysimachia nummularia calyx Calyx.

Flowering - May - August.

Habitat - Streambanks, bottoms, ditches, roadsides. Also cultivated.

Origin - Native to Europe.

Other info. - This weedy yet attractive species can be found scattered throughout most of Missouri. The plant is an escape from lawns and gardens and is now well established in this state. Plants seldom flower, which is why I do not show flowers in the whole plant pic above, but rather spread by creeping stems which root at the nodes and create large mats if left unchecked. Steyermark mentions that the plant makes a good ground cover for shaded, moist areas.
This species can be easily identified by its creeping stems and opposite orbicular leaves.

Photographs taken in the Ozark Scenic Riverways, Shannon County, MO., 6-9-03.

Creeping jenny, moneywort, lysimaque nummulaire

Stems prostrate or trailing (rooting at nodes and often forming mats), simple or branching proximally, 1-5 dm, glabrous or sparsely stipitate-glandular; rhizomes slender to somewhat thickened; bulblets absent. Leaves opposite; petiole 0.1-0.5 cm, eciliate; blade orbiculate to ovate-orbiculate, 1-3.5 × 0.5-3.5 cm, base rounded, decurrent, margins entire, plane, eciliolate, apex rounded, surfaces reddish-brown punctate, glabrous; venation pinnate-arcuate. Inflorescences axillary in medial leaves, solitary flowers. Pedicels 1-8 cm, glabrous. Flowers: sepals 5, calyx streaked with dark resin canals, 5-8 mm, glabrous, lobes ovate to deltate, margins thin; petals 5, corolla yellow, finely streaked with black resin canals, campanulate to rotate, 10-15 mm, lobes with margins somewhat irregularly erose apically, apex rounded to acute, finely stipitate-glandular (sometimes sparsely so); filaments connate ca. 1 mm, shorter than corolla; staminodes absent. Capsules not seen. 2 n = 30, 32, 43 (Europe).

Flowering summer. Wet meadows, seeps, pond edges, stream banks, flood plains, wet roadside ditches, mesic woods; 0-1700 m; introduced; B.C., N.B., N.S., Ont., P.E.I., Que.; Ala., Ark., Calif., Colo., Conn., Del., D.C., Ga., Ill., Ind., Iowa, Kans., Ky., La., Maine, Md., Mass., Mich., Minn., Miss., Mo., Nebr., N.H., N.J., N.Y., N.C., Ohio, Oreg., Pa., R.I., S.C., Tenn., Vt., Va., Wash., W.Va., Wis.; Eurasia.

Lysimachia nummularia has been collected as an adventive in Newfoundland.

Lysimachia nummularia is part of a Eurasian complex of 38 species centered on the Indian subcontinent, whose boundaries are not well understood. North American populations of this species rarely, if ever, produce capsules. Plants of eastern Asia are reported to produce fruit; seed viability is unknown. The species reproduces by vegetative means, often forming extensive mats.
