General Information

Herbs perennial, rhizomatous. Aerial stems present or absent. Leaves distichous, usually large; petiole sheathing at base, apex with a swollen pulvinus; leaf blade pinnately veined, lateral veins parallel, slightly S-shaped. Inflorescences terminal or axillary, borne on leafy shoots or occasionally on separate, leafless shoots from rhizomes, compound, headlike, spicate, or diffuse and much branched, bracteate; bracts each subtending a pair of flowers or a cincinus of paired flowers. Flowers bisexual, asymmetric, paired or rarely borne singly. Sepals 3, free. Corolla lobes 3, often slightly unequal, basally connate into a tube. Staminodes and stamen in 2 whorls: outer whorl with 1 or 2 petaloid staminodes, rarely absent; inner whorl with 1 hooded (cucullate) staminode enclosing terminal portion of pistil at anthesis and bearing a lateral appendage (trigger), 1 thickened and fleshy (callose) staminode, and 1 fertile stamen narrowly petaloid laterally; anther 1-loculed. Ovary inferior, 3-loculed, 1--3 locules fertile; ovules 1 per locule. Style cylindric, adnate to inside of corolla and staminode tube, free portion curved after explosive forward movement (tripping) when released Seeds 1--3, hard, usually arillate.from hooded staminode; stigma scoop-shaped or blunted and 3-cleft. Fruit a capsule, loculicidal, rarely indehiscent or berrylike.

    • Herbs, perennial, from rhizomes. Aerial stems branched or unbranched. Leaves in a basal cluster, both basal and cauline, [or strictly cauline], alternate, differentiated into basal sheath, petiole (occasionally absent), and blade; sheaths often overlapping, supporting stem, open, ligule absent; summit of petiole distinctly differentiated as pulvinus (i.e., region of specialized cells controlling leaf movement, differing in color, often size, from petiole); blade with lateral veins parallel, diverging from prominent midrib. Inflorescences 1--several per aerial shoot, terminal or terminal and lateral on aerial stem [occasionally arising directly from rhizome], scapose or pedunculate [subsessile], compound, headlike or spikelike to diffuse or much branched, bracteate; each bract enclosing pair of flowers or cincinnus of paired flowers [solitary flowers (Monotagma, Monophrynium)]. Flowers bisexual, asymmetric, paired flowers mirror images of each other; sepals and petals differentiated, sepals 3, distinct [rarely connate basally (Megaphyrnium)], petals 3, corolla, staminodes, and style fused basally into tube; fertile stamens 1, occasionally petal-like; anthers 1-locular; staminodes [2--]3--4, outer staminodes [0--]1--2, petal-like, inner staminodes 2, one fleshy (callose staminode), one hooded (cucullate staminode), bearing 1(2 in Thalia) appendage(s), subterminal or medial, fingerlike or flaplike; ovary inferior, 3-carpellate, 3-locular, 1[--3] locule(s) fertile; placentation basal; ovules 1 per locule; terminal portion of style and stigma enclosed in cucullate staminode, explosively released, stout (appendaged in Thalia); stigma cup-shaped. Fruits fleshy [dry] capsules (rarely indehiscent) [berry or achene]; sepals often persistent in fruit. Seeds: aril present [rarely absent]; endosperm scanty or absent; perisperm copious; embryo curved.

      Morphology

      Leaves in two rows, differentiated into an open sheath, stalk and blade, the stalk often winged, but terete and pulviniform towards the apex, this being referred to as the calloused portion (see Fig. 345), the blade sometimes with one straight and one curved side, with closely parallel numerous nerves diverging obliquely from the midrib
