Abstract

Perennial, tufted, shortly rhizomatous or stilt-rooted terrestrial herbs to 1 m tall, shrublike if the branched inflorescence is perennial and the leaves are caducous (Corynotheca). Leaves linear to 80 cm long, mostly basal and 2-ranked. Inflorescence a terminal spike or raceme, if branched with the flowers borne singly or in spicate (Corynotheca) or umbellate (Tricoryne) clusters on the branch apices; flowers and branches subtended by more or less conspicuous bracts. Flowers actinomorphic, sessile or pedicellate and then articulated or non-articulated on pedicels; perianth twisting or not twisting after anthesis, at length deciduous; tepals 6, more or less similar, at the base 3- to 7-nerved, free or united into a tube which may be ½ their length; stamens free, 6 or 3 with or without staminodia, inserted on tepal bases, if 3, affixed to inner whorl of tepals; anther filaments unornamented; anthers dorsifixed, erect, dehiscing introrsely (and also extrorsely Corynotheca) by slits; ovary syncarpous, superior and 3-locular; style simple, filiform, rarely gynobasic (Tricoryne); stigma small, capitate; ovules anatropous or campylotropous, on axile placentas; ovules 1-few, usually 2 per placenta. Fruit a capsule, nut or schizocarp (Tricoryne); seeds black, shiny, arillate or lacking an aril (Arnocrinum), embryo linear-cylindrical, more than 1/3 the length of the seed.
