corolla off-white or tinged with dusky purple, clawed, claw equaling calyx, broadened distally, limb 2-lobed, 3–5 mm, appendages ca. 1 mm;

stamens equaling calyx;

styles 3(–4), equaling calyx.

functionally unisexual, usually bisexual;

calyx obscurely 10-veined, campanulate, 5–8 mm, ca. 1/2 as wide, herbaceous, margins dentate, lobes lanceolate, 1.5–3 mm, apex recurved, subacute to acuminate, puberulent to pilose and glandular, veins without conspicuous, pale commissures;

stamens in functionally staminate flowers equaling corolla, otherwise reduced and included in calyx;

stigmas 3(–4), equaling corolla in functionally pistillate flowers, otherwise included in calyx, papillate along whole length.

Capsules

equaling calyx, opening by 6 (or 8) teeth;

carpophore 2.5–3.5 mm.

green, becoming black, ovoid-ellipsoid, slightly longer than calyx, opening by 3 erect teeth which often split into 6;

carpophore ca. 1.5 mm.

Discussion

Silene suksdorfii appears to be closely related to S. parryi but differs in its broadly winged seeds, smaller size, cespitose habit, and the prominent purple-septate hairs of the calyx, although the latter occasionally are present in S. parryi. It is very similar to, and in Idaho appears to intergrade with, another alpine species, S. sargentii, which has linear leaves and lacks the purple septa in the hairs and the broad wing on the seeds. It is similar also to S. hitchguirei; see discussion under that species.

Silene menziesii is quite variable in the extent to which the inflorescence is developed and in its pubescence. This, coupled with the functionally dioecious nature of the species, has spawned a plethora of names, none of which appear to warrant recognition. The similar S. williamsii from Alaska and the Yukon Territory can be separated by its narrower lanceolate leaves that are broadest near the base and dull, usually brown, tuberculate seeds. Also, its stigmas are papillate only near the top. Silene seelyi is also very similar to S. menziesii but has dark red flowers and leaves that are smaller (to 2 cm in length) and broadest below the middle.
