IncludingAndrosynaceae Salisb., Cyanellaceae Salisb., Lanariaceae Huber ex Dahlgren, WalleriaceaeExcluding Cyanastraceae

Habit and leaf form. Medium or small, generally glabrous herbs. Plants non-succulent. Perennial; with a basal aggregation of leaves, or with neither basal nor terminal aggregations of leaves; cormous, or tuberous. Leaves alternate; spiral, or distichous; sessile; sheathing. Leaf sheaths with free margins. Leaves simple. Lamina entire; linear to lanceolate, or ovate, or orbicular; parallel-veined; without cross-venules; attenuate at the base. Lamina margins entire.

Leaf anatomy. Stomata present; anomocytic. Guard-cells not ‘grass type’.

Lamina dorsiventral. The mesophyll containing calcium oxalate crystals. The mesophyll crystals raphides. Midrib conspicuous. Minor leaf veins without phloem transfer cells (1 genus). Vessels absent.

Stem anatomy. Secondary thickening absent. Xylem without vessels.

Root anatomy. Root xylem with vessels; vessel end-walls scalariform.

Reproductive type, pollination. Unisexual flowersabsent. Plants hermaphrodite.

Inflorescence, floral, fruit and seed morphology. Flowers aggregated in ‘inflorescences’. Inflorescences scapiflorous to not scapiflorous; terminal; simple or compound racemes or thyrses; espatheate. Flowers bracteate; regular, or somewhat irregular; when irregular, somewhat zygomorphic. The floral irregularity (when present) involving the androecium (e.g. sometimes with one anther much larger than the rest), or involving the perianth and involving the androecium. Flowers 3 merous; cyclic; tetracyclic. Perigone tube present (short), or absent.

Perianthof ‘tepals’ (the members spreading or reflexed); 6; free, or joined; 2 whorled; isomerous; petaloid; similar in the two whorls; white, or yellow, or violet, or blue.

Androecium6. Androecial members adnate; all equal, or markedly unequal; free of one another to coherent (via shortly connate filament bases). Androecium exclusively of fertile stamens, or including staminodes. Staminodes when present, 1–3(–5). Stamens (1–)3–6; reduced in number relative to the adjacent perianth to diplostemonous; oppositiperianthial (when 3), or alterniperianthial; filantherous, or with sessile anthers. Anthers separate from one another, or connivent, or cohering (connate in Conanthera); basifixed (mostly), or dorsifixed (peltate, in Tecophilaea); non-versatile;apically dehiscing via pores, or dehiscing via short slits (dehiscing longitudinally only in Lanaria, a dubious inclusion in this family); introrse; appendaged, or unappendaged. The anther appendages apical, or basal, or apical and basal (the connective sometimes produced at both ends). Anther epidermis persistent. Microsporogenesis simultaneous. Tapetum glandular (?). Pollen grains aperturate; 1 aperturate; sulcate (with an operculum); 2-celled.

Gynoecium 3 carpelled. Carpels isomerous with the perianth. The pistil 3 celled.Gynoecium syncarpous; eu-syncarpous; partly inferior (usually), or superior (only in Walleria, which probably belongs elsewhere). Ovary 3 locular. Gynoecium stylate. Styles 1 (the style filiform); apical. Stylar canal present. Stigmas 1; more or less 3 lobed; small, capitate. Placentation axile. Ovules 4–50 per locule (‘several to many’); in two rows; non-arillate; anatropous; bitegmic; crassinucellate. Outer integument contributing to the micropyle, or not contributing to the micropyle. Embryo-sac development Polygonum-type. Polar nuclei fusing prior to fertilization. Antipodal cells formed; 3; not proliferating; ephemeral to persistent. Synergids pear-shaped. Endosperm formation nuclear (in Cyanella). Endosperm haustoria present, or absent; when formed, chalazal.

Fruit non-fleshy; dehiscent; a capsule. Capsules apically loculicidal. Fruit many seeded. Seeds endospermic; small. Embryo well differentiated. Testa encrusted with phytomelan (usually), or without phytomelan (seemingly only Walleria, which may belong elsewhere); at least sometimes black (e.g. Cyanella). Polyembryony recorded (in Cyanella).

Geography, cytology. Holarctic, Paleotropical, Neotropical, Cape, and Antarctic. Madrean. Temperate to tropical. Pacific North and South America, central and South Africa.

Taxonomy.Subclass Monocotyledonae. Dahlgren et al. Superorder Liliiflorae; Asparagales. APG 3 core angiosperms; Superorder Lilianae; non-commelinid Monocot; Order Asparagales.

Species 22. Genera 7, or 8; Conanthera, Cyanella, Lanaria(?), Lophiola,Odontospermum, Tecophilaea, Walleria, Zephyra.

General remarks. Lanaria may merit a monogeneric family: see Rudall et al. (1998).


  • Conanthera (Chittenden).
