[Lagenophora.

dry or scarious margins. Receptacle convex, naked. Ray-florets in 1–3 series, female, fertile, ligulate or rarely short and tubular; ligule usually white. Disc-florets numerous, hermaphrodite, tubular, with a broad 5-toothed limb. Anthers obtuse at the base. Style-branches of the disc-florets long, flattened, with lanceolate or triangular tips. Achenes compressed, abruptly contracted at the top into a more or less distinct beak; those of the disc-florets often narrower and sterile. Pappus wanting.

A small genus of about 16 species, mainly found in Australia and New Zealand, but with outlying species in eastern Asia, the Sandwich Islands, and extra-tropical South America.

Glabrate or pilose. Leaves mostly radical; petioles slender; blade orbicular or broadly oblong. Heads ¼–½ in. diam. Achenes small, nearly straight 1. L. Forsteri.
Glabrate or pilose, slender. Leaves mostly radical; petioles slender; blade orbicular or obovate. Heads 1/51/3 in. diam. Achenes larger, curved or falcate 2. L. petiolata.
Scaberulous. Leaves mostly cauline; petioles slender; blade oblong- spathulate. Heads ¼–½ in. diam. 3. L. Barkeri.
Glabrate or pilose. Leaves mostly cauline; petioles slender; blade ovate. Achene oblanceolate 4. L. purpurea.
Softly hirsute. Leaves all radical; petiole broad, flat; blade obovate, pinnatifid. Heads ¼–½ in. diam. 5. L. pinnatifida.
Leaves hirsute, all radical; petioles short, broad; blade oblong- spathulate. Heads ¼–⅓ in. diam. Achene glabrous 6. L. lanata.

L. linearis, Petrie in Trans. N.Z. Inst. xxv. (1893) 471, is Brachycome lineata, Kirk. L. emphysopus, Hook. f., an Australian species, has become naturalised on Banks Peninsula and near Wellington. It has the habit, fleshy roots, and hirsute leaves of L. lanata, but can at once be distinguished by the short stout scapes and almost tubular ray-florets.


1. L. Forsteri, D.C. Prodr. v. 307.—A small daisy-like herb, either tufted or with creeping and rooting stolons furnished with tufts of radical leaves at the nodes. Leaves all radical or cauline, 1½–2in. long; petiole long, slender; blade ½–1 in., orbicular or orbicular-oblong to obovate, obtuse, narrowed into the petiole, coarsely crenate-dentate or almost lobed, almost glabrous or more or less hirsute. Scape 1–6 in. long, slender, naked or with 1–3 minute linear bracts. Heads ¼–½ in, diam.; involucral bracts linear, acute; margins thin, scarious, entire or finely jagged. Ray-florets numerous; ligules white, revolute. Achenes small, linear-obovate, straight or very slightly curved, abruptly narrowed into a short hardly viscid beak; margins thickened.—A. Cunn. Precur. n. 436; Raoul, Choix, 45; Hook. f. Fl. Nov. Zel. i. 125; Handb. N.Z. Fl. 137; Kirk, Students Fl. 256. Calendula pumila, Forst. Prodr. n. 305. Microcalia australis, A. Rich. Fl. Nouv.
