Species

Angiosperms > Caryophyllales > Caryophyllaceae > Stellaria

Characteristics

Stems procumbent to weakly ascending, sometimes rooting at some nodes, glabrescent with scattered hairs to glabrous in the lower parts or with hairs retained in the furrows.. Leaves all petiolate; blades ovate, acute and apiculate or shortly acuminate, rounded or slightly cuneate at the base, when well formed 1.5–4.5 cm. long and 1–3 cm. broad, midrib moderately conspicuous, lateral veins rather obscure but all anastomosing very close to the margin, with scattered and often glandular hairs; petioles 0.4–3 cm. long, slightly amplexicaul at the base and there usually more or less connate, glandular-hirsute.. Inflorescence terminal to the main branches, densely but shortly glandular-pubescent; pedicels at first very short but elongating to 8 mm.. Sepals ovate-lanceolate, acute or shortly acuminate, 4.5–6 mm. long, glandular on the abaxial surface.. Petals strongly bifid, often about equal in length to or slightly shorter than the sepals or up to half as long again as the sepals, white.. Stamens 10, when all fertile.. Styles 3.

Leaves all petiolate; lamina up to 4·5 × 3 cm., ovate, apex acute and apiculate or shortly acuminate, rounded or slightly cuneate at the base, with scattered and often glandular hairs on both sides, midrib conspicuous, lateral nerves obscure but anastomosing close to the margins and producing a submarginal nerve, petiole up to c. 2 (3) cm. long, slightly amplexicaul and connate at the base, glandular-hirsute.
Weak, procumbent or ascending herb, sometimes rooting at the nodes; stems with scattered hairs in the upper internodes, often glabrous in the lower internodes or with hairs retained in the stem furrows.
Inflorescences lax, terminal, densely glandular-pubescent; bracts c. 3·5 × 1 mm., lanceolate, glandular-pubescent; pedicels short at first but elongating to c. 8 mm. long.
Petals 5, white, somewhat rhombic, bifid c. 1/3 of the way down, from slightly shorter to 1 1/2 times the length of the sepals.
Sepals 5, 4·5–6 × 1·5–2 mm., lanceolate to ovate-lanceolate, acute or shortly acuminate, glandular outside.
Seeds (often only one developing to maturity) brown, c. 3 mm. in diam., discoid; testa lightly striate.
Stamens usually 10 but sometimes fewer by reduction, filaments c. 3 mm. long, swollen at the base.
Capsule globose, slightly shorter than the persistent sepals, opening at the apex by 6 valves.
Ovary ovoid, c. 3-ovulate; styles 3, c. 1·5 mm. long, slender.
