Rhodoplexia preissii Harvey in W.J. Hooker 1844, pl. 613.

Haloplegma cornu-damae Kützing 1862: 19, pl. 63a–c.

Thallus (Fig. 134A) red-brown, flat and complanately branched, (5–) 10–20 cm high, much branched with main branches 5–10 mm broad bearing laterals marginally of various sizes for 3 or 4 orders, mostly 1–2 mm thick, ultimate branches lobed to pointed, margins smooth, surface felt like. Stipe 2–20 mm long, 1–3 mm broad, holdfast rhizoidal, 2–10 mm across; epilithic or epiphytic on Ainphibolis. Structure. Marginal apices regularly fringing the blades (Fig. 134B) but not conspicuous due to overtopping by long, curved filaments of the surface clusters; rectangular network filaments present but not conspicuous, cells 35–55 µm in diameter and L/D 3–8 (–20). Surface clusters (Fig. 134C) 400–700 µm long, basally branched but with long, unbranched, curved, gently tapering ends 250–500 µm and 15–32 cells long, cells 18–30 µm in diameter and L/D 1–1.5. Cells multinucleate; rhodoplasts discoid to elongate.

Reproduction: Gametophytes dioecious. Carpogonial branches (Fig. 141D) borne on short branches on lower cells of surface clusters, details uncertain. Carposporophytes (Fig. 134D) lying within and loosely surrounded by filaments of the surface clusters, with 3–5 rounded gonimolobes 400–700 µm across, all cells forming ovoid carposporangia 10–20 µm in diameter. Spermatangial heads (Fig. 134E, F) terminal on the unbranched filaments of the surface clusters, ovoid, 25–35 µm in diameter, with 5–8 axial cells bearing whorls of cells producing spermatangia.

Tetrasporangia (Fig. 134G) terminal on short branches from the lower to mid cells of the (otherwise) unbranched surface filaments, slightly ovoid, 20–45 µm in diameter, tetrahedrally divided.

Distribution map based
on current data relating to
specimens held in the
State Herbarium of SA

Distribution: Widespread in tropical waters, especially the Indian Ocean.

In southern Australia, from Shark Bay, W. Aust. (Huisman et al. 1990, p. 96) to Walkerville, Vic., and around Tasmania.

Taxonomic notes: H. preissii is a common alga on rough-water coasts of southern Australia, ranging from shaded pool situations to deep water.

Var. B flabelliforme Harvey (1859b: 330) from near Georgetown, Tasmania, appears to be only a slender form of the species, and H. cornu-damae is typical of the species.

Weber-van Bosse (1913, p. 136) recorded H. preissii from Cargados Carajos (N of Mauritius); this tropical locality is well outside the Australian distribution and the specimen should be checked, especially as to similarities with H. anweri Shameel & Nizamuddin (1972, p. 434). Cribb (1983, p. 92) refers the W.v. Bosse record to H. duperreyi.
