Morphology General Habit
Perennial scandent or erect shrubs or subshrubs, branching; rhizomes sympodial from where the branches are growing; roots often swollen and fusiform
Morphology General Spines
Spines present or absent; when present these are formed usually from the reduced leaves, occasionally from branches
Morphology Leaves
Leaves normally reduced and scale-like, the assimilating function taken by modified green branches (cladodes); in some genera the branches are transformed into flattened, leaf-like cladodes (phylloclades)
Morphology Stem Cladodes
Cladodes solitary or fascicled, subulate, angled or linear
Morphology Reproductive morphology Inflorescences
Inflorescence axillary or terminal, solitary, fascicled or assembled in racemes or “ umbels”
Morphology Reproductive morphology Flowers
Flowers unisexual or bisexual, actinomorphic, small, erect or pendulous
Morphology Reproductive morphology Flowers Perianth
Perianth with 6 tepals in two series, all similar in shape, free or fused at the base, white, cream, yellow or green
Morphology Reproductive morphology Flowers Androecium
Stamens 6, in two series, fused to the perianth segments, present both in unisexual and bisexual flowers, non-functional in female unisexual flowers; filaments free from each other, anthers introrse, dorsifixed; pollen grains sulcate
Morphology Reproductive morphology Flowers Gynoecium
Pistil with 3 carpels united to form a 2– 3-locular ovary with 1– 12 ovules in each locule; placentation axile; style short with capitate or lobed stigma
Morphology Reproductive morphology Fruits
Fruit a globose berry with 1– 2(– 3) seeds
Morphology Reproductive morphology Seeds
Seeds black, globose or truncate on one side, convex on the other
Distribution
Family represented by the genus Asparagus with two subgenera, subgenus >i>Asparagus and subgenus >i>Myrsiphyllum (S.T. Malcomber & Sebsebe Demissew in Kew Bull. 48(1): 63– 78 (1993)). The members are widely distributed in the old world. Most species are found in arid tropical regions and Mediterranean climates

Morphology General Habit
Herbs with perennial tubers and annual aerial parts, glabrous or partly pubescent (not in East Africa)

Morphology Reproductive morphology Inflorescences
Inflorescence a simple raceme, few-many-flowered, cylindrical to corymbose, dense to lax, upper flowers sometimes sterile or aborted; peduncle erect to suberect, sometimes subtended by a leaf-like sheath; bracts minute, solitary, at the base of a single pedicel; pedicels short to long, erect to spreading, articulated at the apex
Morphology Reproductive morphology Flowers
Flowers small, regular, rotate, campanulate or triangular, opening in the sun; tepals in 2 whorls of 3, connate at the base, subequal to equal or dimorphic, white, pink, yellow or green and often with a darker coloured midnerve, persistent
Morphology Reproductive morphology Flowers Androecium
Stamens 6, hypogynous, joined to the base of the tepals; filaments filiform to broadly lanceolate, white, yellow, orange or purple blotched; anthers, dorsifixed, versatile, subglobose to oval, introrse
Morphology Reproductive morphology Flowers Gynoecium
Ovary superior, sessile, with 3 locules, each with 2-6 axile ovules; style terete; stigma apical, small
Morphology Reproductive morphology Fruits
Fruit a loculicidal capsule, turbinate to ovoid
Morphology Reproductive morphology Seeds
Seeds oval to comma-shaped, densely covered with hairs, silvery white when fresh, turning brown with age
