Descriptions
Pleurophyllum Hook.f.
Capitula large, in racemes; receptacle flat, alveolate; phyll. herbaceous, in 2-3 series. Ray-florets pistillate, ligulate; disk-florets narrow tubular-campanulate, perfect, segs recurved. Anther-cells shortly and bluntly produced at base; style-arms flattened, with lanceolate unreceptive tips. Achenes compressed, striate, setose. Pappus of rigid unequal scabrid hairs. Robust perennial herbs closely allied to . Genus endemic to the Auckland, Campbell, Antipodes and Macquarie Is.
Stoloniferous herb with thick woody multicipital basal stock. Living leaves densely imbricating and forming rosettes at tips of branchlets and sometimes at ends of leafy stolons. Leaves glossy as though varnished, glabrous; venation simple with lateral veins of sheath not extending into the lamina. Ptyxis plain. Inflorescence scapose and monocephalous. Receptacle obconic; phyllaries in several series, bearing eglandular uniseriate hairs only. Ray florets ligulate, ♀, white, occasionally pale rose especially near tips, limb and tube clad in scattered hairs. Disc florets tubular, S, purple or occasionally yellow, cyathiform above point of insertion of stamen filaments and usually cylindrical below, although occasionally gradually narrowing towards corolla base; corolla hairs eglandular biseriate and uniseriate; stamen tip usually obtuse or if acute then short, anther tails present but shorter than the basally narrowed filament collar; style arms short, terminal appendage broadly triangular and bearing long collecting hairs on back and margin. Pappus bristles unequal, in more than one series, plumose with long crowded teeth. Achene obconic, clad in duplex hairs.
Genus novum differens ab Celmisia Cass. foliis eglandulosis vernicosis, floribus disci purpureis, styli ramis brevibus latisque, staminibus appendicibus obtusis terminalibus et collis angustatis ornatis, plumosis pappi setis et acheniis obconicus.
