Herbs, perennial, forming large mats or clumps by leafy rhizomes; rhizomes fleshy, often with prominent nodal buds and small membranous leaves. Taproots slender. Stems prostrate to decumbent, flowering stems ascending or weakly erect, simple or branched, terete or weakly 4-angled. Leaves not basally connate, sessile; blade 1-veined or obscurely so, usually elliptic to ovate, less commonly lanceolate to oblanceolate, obovate, or broadly elliptic, succulent, apex acute to acuminate or apiculate. Inflorescences terminal, open, leafy, 1–6-flowered cymes or axillary and flowers solitary; bracts paired, foliaceous. Pedicels erect. Flowers functionally unisexual or, occasionally, staminate plants also with some bisexual; perianth and androecium subperigynous; hypanthium minimal; sepals 5(–6), distinct, green, narrowly ovate to elliptic, 3.5–7 mm, herbaceous, margins pale, scarious, apex obtuse or acute to apiculate, not hooded; petals absent or 5(–6), white, base clawed, blade apex emarginate; nectaries at base of filaments opposite sepals enlarged on both sides of filament, slightly reduced in pistillate flowers; stamens 10, fertile in staminate flowers, fewer or abortive in pistillate flowers, arising from rim of very brief hypanthium disc; filaments distinct; staminodes absent; styles (2–)3–5(–6), filiform, 1–2 mm, shorter and erect in staminate flowers, glabrous proximally; stigmas (2–)3–5(–6), linear along adaxial surface of styles, minutely papillate (30×). Capsules globose, inflated, opening by 3 spreading valves; carpophore absent. Seeds 3–15, reddish brown to dark reddish or yellowish brown, narrowly to broadly obovate, laterally compressed, smooth to minutely papillate, marginal wing absent, appendage absent. x = 15.
Distribution
Temperate and arctic North America, n Eurasia.
Discussion
Species 1.
The resemblance in habit between Honckenya and Wilhelmsia previously presumed to represent convergence has proven to indicate a close relationship based on recent molecular studies (M. Nepokroeff et al., unpubl.).
Selected References
None.
