The World Flora Online

Herbes avec bulbes ou rhizomes. Feuilles en rosette basale ou distiques, depuis le sommet du bulbe ou du rhizome; pétiole, lorsqu'il existe, parfois embrassant, formant une pseudo-tige; limbe simple, entier, linéaire à lancéolé ou rubané. Hampe florale aphylle, centrale ou latérale, par rapport aux feuilles avec une à beaucoup de fleurs groupées en inflorescence ombelliforme, sous-tendue par un involucre de 1 à plusieurs bractées et avec des bractées hyalines éphémères entre les fleurs. Fleurs voyantes, hermaphrodites, trimères, régulières ou moins souvent légèrement irrégulières. Pétales en 2 séries, égaux à subégaux, insérés au-dessus de l'ovaire, libres ou en partie soudés en un tube court ou long. Étamines 3 + 3, opposées aux pièces périanthaires, insérées à leur base; anthères dorsifixes, versatiles, introrses, déhiscentes sur toute leur longueur par une fente. Ovaire triloculaire, avec peu ou beaucoup d'ovules par loge; placentation axile; style long et grêle, avec un stigmate capité ou trilobé. Fruit : capsule souvent loculicide, ou baie. Graines globuleuses ou aplaties avec un albumen charnu et un petit embryon.

Flowers usually showy, bisexual actinomorphic, solitary to many and umbellate at the top of the scape, subtended by an involucre of two or more (rarely only one) usually membranous bracts Perianth inserted below or usually above the ovary, petaloid, often withering and persisting, with or without a tube; segments or lobes 6, in 2 series, all equal and similar or the inner smaller or larger than the outer; corona often present Herbs with a tunicated bulbous rootstock or rarely a rhizome Leaves few from the base of the stem or apex of the bulb, more or less linear, with parallel nerves and transverse secondary nerves Ovules mostly numerous in each loculus Stamens 6, opposite the segments, hypogynous or inserted on the tube or towards the base of the segments; filaments free or expanded at the base and connate and forming a "false" corona; anthers 2-locular, introrse, basifixed or versatile, opening by slits lengthwise Ovary superior or inferior, 3-locular, with usually axile placentas; style slender, with a capitate or 3-lobed stigma Seeds with fleshy endosperm and small embryo, sometimes winged Fruit a capsule or a berry Perianth inserted below or usually above the ovary, petaloid, often withering and persisting, with or without a tube; segments or lobes 6, in 2 series, all equal and similar or the inner smaller or larger than the outer; corona often present Herbs with a tunicated bulbous rootstock or rarely a rhizome Leaves few from the base of the stem or apex of the bulb, more or less linear, with parallel nerves and transverse secondary nerves Ovules mostly numerous in each loculus Stamens 6, opposite the segments, hypogynous or inserted on the tube or towards the base of the segments; filaments free or expanded at the base and connate and forming a "false" corona; anthers 2-locular, introrse, basifixed or versatile, opening by slits lengthwise Ovary superior or inferior, 3-locular, with usually axile placentas; style slender, with a capitate or 3-lobed stigma Seeds with fleshy endosperm and small embryo, sometimes winged Fruit a capsule or a berry

Herbs with bulbs or rhizomes Leaves in a basal rosette from the apex of the bulb or rhizome; petioles, if present, sometimes sheathing to form a false stem; blade simple, entire, linear to lanceolate or strap-shaped Scape leafless, central or lateral in relation to the leaves, with 1–many flowers in an umbel-like inflorescence, subtended by an involucre of 1–many bracts and with ephemeral hyaline bracts between the flowers Flowers showy, bisexual, 3-merous, regular or less often slightly irregular Tepals in 2 series, equal to subequal, inserted above the ovary, free or partly united into a short or long tube; corona sometimes present Stamens 3 + 3, opposite the perianth-segments, inserted at their base or in the tube; filaments free, partly fused with the perianth or united into a cup (false corona) at the base; anthers basifixed (not in East Africa) or dorsifixed, often versatile, introrse, opening lengthwise by slits Ovary 3-locular, each locule with (1–2–) many axile ovules; style long and slender, with capitate or 3-lobed stigma Fruit a capsule, often loculicidal, or a berry Seeds globose or flattened, sometimes winged, with fleshy endosperm and small embryo Leaves in a basal rosette from the apex of the bulb or rhizome; petioles, if present, sometimes sheathing to form a false stem; blade simple, entire, linear to lanceolate or strap-shaped Scape leafless, central or lateral in relation to the leaves, with 1–many flowers in an umbel-like inflorescence, subtended by an involucre of 1–many bracts and with ephemeral hyaline bracts between the flowers Flowers showy, bisexual, 3-merous, regular or less often slightly irregular Tepals in 2 series, equal to subequal, inserted above the ovary, free or partly united into a short or long tube; corona sometimes present Stamens 3 + 3, opposite the perianth-segments, inserted at their base or in the tube; filaments free, partly fused with the perianth or united into a cup (false corona) at the base; anthers basifixed (not in East Africa) or dorsifixed, often versatile, introrse, opening lengthwise by slits Ovary 3-locular, each locule with (1–2–) many axile ovules; style long and slender, with capitate or 3-lobed stigma Fruit a capsule, often loculicidal, or a berry Seeds globose or flattened, sometimes winged, with fleshy endosperm and small embryo

Herbs perennial, rarely shrubby or treelike, often with bulbs, corms, rhizomes, or tubers. Leaves basal or cauline, often narrow, margin entire or spiny. Inflorescence a terminal spike, umbel, raceme, panicle, or flowers solitary. Flowers bisexual, actinomorphic or zygomorphic, usually subtended by 1 to several spathaceous involucres. Perianth segments 6, in 2 whorls, free or connate to form a short tube, with or without a corona. Stamens 6, inserted at perianth throat or at base of segments; filaments sometimes basally connate; anther dorsifixed or basifixed, mostly introrse. Ovary inferior, 3-loculed; ovules few to many per locule; placentation axile. Style slender; stigma capitate or 3-lobed. Fruit a capsule, usually loculicidal, sometimes dehiscing irregularly, rarely a berry. Seeds with endosperm.
