Agavaceae

Plants usually perennial, occasionally epiphytic, sometimes monocarpic or polycarpic, monoecious, dioecious, or polygamodioecious, small to gigantic, sometimes arborescent, usually scapose. Stems subterranean or aboveground, sometimes branched. Leaves simple, annual or long-lived, in terminal rosettes or occasionally cauline, sessile or occasionally pseudo-petiolate; blade linear, lanceolate, oblanceolate, ovate, or elliptic, fibrous, thin and flexible, thick and rigid or succulent, or fibrous, often glaucous, margins entire, serrulate, dentate, denticulate, corneous, or filiferous, apex rigid or flexible, sometimes pungent, often with short or long spine. Inflorescences terminal or axillary spikes, racemose or paniculate, sometimes umbellate, bracteate, often huge; bracts ascending or erect, occasionally reflexed, leaflike proximally, scalelike distally. Flowers 6-merous, bisexual or functionally unisexual; perianth of 2 similar petallike whorls, semisucculent; tepals distinct or connate into tube, apex glandular or glandular-pubescent; stamens included or exserted; filaments often broadened and succulent, glabrous, pubescent, or papillose; anthers versatile, dehiscence longitudinal; ovary superior or inferior, 3-locular or occasionally 1-locular, 3-angled, ovoid, or cylindrical, with axillary or rarely parietal placentation; style included or exserted; stigmas 1 or 3, 3-lobed or capitate; pedicel usually distinct, articulate or not, rarely absent. Fruits occasionally baccate, usually capsular and sometimes winged or lobed, or indehiscent and dry or fleshy. Seeds 1€“3(€“many) per locule, flattened, 3-angled, hemispheric, ovoid, obovoid, or globose.[1] [more]

Alliaceae

Alliaceae is a of herbaceous perennial flowering plants. They are monocots, part of order Asparagales. The family has been widely but not universally recognised; in the past, the plants involved were often treated as belonging to the family Liliaceae, and still are by some botanists. [more]

Amaryllidaceae

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.[2] [more]

Hemerocallidaceae

A family of flowering plants that includes daylilies and New Zealand flax. The genus Hemerocallis was assigned its own family name in 1982 by Dahlgren and Clifford. (See pp. 36-39, "Biosystematics," by Barr Daylily Journal, vol. 42, no. 2, fall 1987. Not all authorities agree, and some place the genus in the family Asparagales. In the family, pedicels are articulated, septal nectaries infralocular, and the ovary superior. Other details: Habit various; flavonols, napthoquinones, saponins +; roots often swollen; mucilage cells 0; raphides 0; cuticular wax rodlets parallel; leaves (spirally) 2-ranked, conduplicate to flat-conduplicate, keeled, the keel unifacial, sheath closed; inflorescence various, (bracteoles lateral); pedicel usu. articulated; (flowers monosymmetric, median tepal of outer whorl adaxial - Hemerocallis), T tube short (1/2 way - Hemerocallis; 0), filaments often ornamented, (anthers centrifixed), pollen usu. trichotomosulcate, infra-locular septal nectaries +, 1-many tenuinucellate ovules/carpel, nucellar cap +, chalazal nucellus well developed; endosperm usu. helobial, stigma dry (wet); fruit also a berry (nut, schizocarp); seeds ovoid, (with strophiole/aril); endosperm hemicellulosic, embryo also short; n = 4 [Agrostocrinum], 8, 9, 11, 12, chromosomes 0.8-10 µm long; (cotyledon not photosynthetic - Dianella), epicotyl long or not (hypocotyl 0; collar +), primary root well developed, branched or not.

Hyacinthaceae

Hyacinthaceae is the of a family of flowering plants. The plants are herbaceous perennials that grow from bulbs, and include several popular spring-blooming garden plants, including Hyacinth (Hyacinthus), grape hyacinth (Muscari), bluebell (Hyacinthoides) and squill (Scilla). [more]

At least 2,604 species and subspecies belong to the Family Hyacinthaceae.
