Treatment appears in FNA Volume 5. Treatment on page 139.

Plants maritime, glabrous; rhizomes spreading. Stems simple or branched, 5–25 (–50) cm. Leaf-blades usually long-elliptic to ovate, sometimes lanceolate to oblanceolate, obovate, or broadly elliptic, 4–46 × 0.5–20 mm, succulent, margins often crenulate, apex acute to acuminate or apiculate. Pedicels 2–10 (–26) mm. Flowers strongly honey-scented; sepals ovate, 3.5–7 mm; petals spatulate to narrowly oblanceolate, abruptly constricted toward base, 2.5–6 mm in staminate flowers, 0.8–2 mm in pistillate flowers; filaments 2.5–5 mm in staminate flowers; anthers 0.5–0.7 mm, 0.5–0.8 mm in pistillate flowers. Capsules ovoid to subglobose, 5–10 × (4.5–) 5–12 mm, fleshy or chartaceous. Seeds 2–4 mm, rugulose. 2n = 66, 68, 70.

Discussion

Subspecies 4 (3 in the flora).

Honckenya peploides is polymorphic. A number of species and infraspecific taxa have been described from various parts of its geographical range. Recently, four subspecies of H. peploides have been recognized (A. Kurtto 2001b; V. V. Petrovsky 1971, 2000), as here; subsp. peploides occurs along European coasts. Honckenya is subdioecious (Petrovsky 1971, 2000; T. Tsukui and T. Sugawara 1992), and is pollinated largely by small bees, hover-flies, flies, and ants (Tsukui and Sugawara). The report of Honckenya (as Ammodenia) in Chile is an error based on G. Macloskie (1903–1914, vol. 1) (C. Marticorena, pers. comm.).
