Silene stellata
starry campion, widow's frill
several, simple proximal to inflorescence, 30–80 cm, puberulent, becoming subglabrous near base.
withering proximally, in whorls of 4, ± sessile to short-petiolate, largest in mid-stem region;
blade lanceolate to ovate-lanceolate, 3–10 cm × 4–40 mm, apex acuminate, puberulent on both surfaces, sparsely so adaxially.
paniculate, open, bracteate, bracteolate, branches elongate, puberulent;
bracts and bracteoles linear-lanceolate, 2–15 mm.
straight, often with 1 or 2 pairs of bracteoles, slender, 1/2–3 times calyx, glabrous or scabrous-puberulous.
calyx obscurely 10-veined, broadly campanulate, becoming obtriangular in fruit, 7–11 × 6–10 mm, herbaceous, margins dentate, very narrow, membranous, sparsely puberulent, lobes broadly triangular, 2–3 mm;
corolla white, ca. 2 times longer than calyx, limb obtriangular, narrowed into claw, divided ca. 1/2 its length into 4–12 lobes, appendages absent;
stamens equaling petals;
styles 3, longer than petals.
globose, opening by 3 broadly triangular teeth;
carpophore 2–3 mm.
dark brown, reniform, ca. 1 mm, papillate.
= (34), 48.
Silene stellata
Silene stellata is a very distinct species with its broadly lanceolate leaves in groups of four at each node, and its brilliant white, multilobed petals. Two varieties are recognized by some workers: var. stellata, with glabrous pedicels; and var. scabrella, with scabrous pedicels. The former tends to have longer, more slender pedicels and be more common towards the northeast, whereas the latter tends to be more western. The correlation of characters and distribution is poor, however, and intermediate plants are often encountered.
Silene stellata was collected near the Grand River, Cambridge, Ontario, in 1941, but was probably introduced there and has not been seen since.
