Lenormandia marginata, from Harvey (1847–1849).

Belongs within: Rhodomelaceae.

The Amansieae are red algae with an erect, usually multi-branched thallus bearing linear branches (Womersley 2003).

Characters (from Womersley 2003): Thallus erect, usually much branched, branches compressed to flat or foliose, usually with conspicuous midrib and lateral wings, margins entire or dentate, blades ecorticate or corticate. Apices dorsiventral and bilateral, straight or often revolute to varying degrees, with single apical cell, protruding or not, segmenting usually transversely to axial filament cutting off 5 or 6 pericentral cells, with or without pseudopericentral cells (cut off laterally from pericentral cells and lying in the ring of pericentral cells), lateral pericentral cells dividing to form wings of blades. Medulla 1–3 cells thick, cells in some taxa in layers or interposed to form (surface view) chevrons or rhombic areolation; cortex 1–2 cells broad, surface bare or covered with short, dense, proliferations. Branching usually endogenous from midrib or wings, or adventitious from cortex. Trichoblasts apical or arising adventitiously from cortical cells, or absent apart from much reduced and associated with reproduction. Gametophytes dioecious, usually with short, erect, fertile processes. Procarps arising on reduced trichoblasts (soon polysiphonous), carpogonial branches 4-celled; carposporophytes with basal fusion cell and branched gonimoblast with clavate terminal carposporangia; cystocarps ovoid, usually stalked; pericarp ostiolate, several cells thick. Spermatangial organs on short, polysiphonous, processes on blades, ovoid and with 1–2 sterile basal cells. Tetrasporangial stichidia on blade surface or on short processes, corticated, compressed, with paired tetrasporangia per segment, in longitudinal rows.
