L. Watson and M. J. Dallwitz


Anemarrhenaceae Conran, M.W. Chase & Rudall

~ Anthericaceae

Habit and leaf form. Herbs. Perennial; with a basal aggregation of leaves; shortly rhizomatous. Leaves alternate; spiral (?); sheathing; with ‘normal’ orientation; simple. Lamina entire; linear; parallel-veined; without cross-venules (?). Lamina margins entire. Leaves with a persistent basal meristem, and basipetal development (?).

Leaf anatomy. Lamina dorsiventral.

Stem anatomy. Secondary thickening absent.

Reproductive type, pollination. Fertile flowers hermaphrodite. Plants hermaphrodite (with the supposedly dioecious Terauchia representing a smut-induced monstrosity).

Inflorescence, floral, fruit and seed morphology. Flowers aggregated in ‘inflorescences’; in panicles (these condensed, spicate). Inflorescences not scapiflorous; terminal; terminal, erect, pedunculate, leafy, spicate condensed panicles. Flowers regular; 3 merous; tetracyclic. Perigone tube present (the tepals connivent into a short tube).

Perianth of ‘tepals’; 6; free (above the tube); 2 whorled; isomerous; sepaloid to petaloid (?); similar in the two whorls; green to white, or purple, or brown (with brownish veins); persistent; non-accrescent.

Androecium 3. Androecial members adnate (to the inner or outer tepals); all equal; free of one another; 1 whorled. Androecium exclusively of fertile stamens. Stamens 3; isomerous with the perianth; alterniperianthial, or oppositiperianthial (?); filantherous (the filaments short and flat). Anthers basifixed (linear); non-versatile; dehiscing via longitudinal slits; introrse. Microsporogenesis successive.

Gynoecium 3 carpelled. Carpels isomerous with the perianth. The pistil 3 celled. Gynoecium syncarpous; eu-syncarpous; superior. Ovary 3 locular. Gynoecium stylate. Styles 1; apical. Stigmas 1; capitate (small). Placentation axile. Ovules 2 per locule; anatropous.

Fruit non-fleshy; dehiscent; a capsule. Capsules loculicidal. Dispersal unit the seed. Fruit 3–6 seeded. Seeds endospermic (endosperm fleshy); fusiform-triangular. Seeds without starch. Cotyledons 2. Embryo cylindric. Testa encrusted with phytomelan; black.

Seedling. Hypocotyl internode absent. Cotyledon hyperphyll elongated; more or less circular in t.s. Coleoptile absent.

Geography, cytology. Holarctic, or Paleotropical. North China.

Taxonomy. Subclass Monocotyledonae. Superorder Liliiflorae; Asparagales. Species 1. Genera 1; Anemarrhena only.

Conran et al. (1997): description insufficiently detailed, and inadequately cross-referenced with Anthericaceae.

Economic uses, etc. Cultivated ornamental.
