According to Flora of Tropical East Africa[FTEA]
Asparagaceae, Sebsebe Demissew. Flora of Tropical East Africa. 2006
- Perennial scandent or erect shrubs or subshrubs, branching; rhizomes sympodial from where the branches are growing; roots often swollen and fusiform
- Spines present or absent; when present these are formed usually from the reduced leaves, occasionally from branches
- 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)
- Cladodes solitary or fascicled, subulate, angled or linear
- Inflorescence axillary or terminal, solitary, fascicled or assembled in racemes or “ umbels”
- Flowers unisexual or bisexual, actinomorphic, small, erect or pendulous
- Perianth with 6 tepals in two series, all similar in shape, free or fused at the base, white, cream, yellow or green
- 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
- 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
- Fruit a globose berry with 1– 2(– 3) seeds
- Seeds black, globose or truncate on one side, convex on the other
- 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

Eriosphermaceae, Christopher Whitehouse, B.A.. Flora of Tropical East Africa. 1996
- Herbs with perennial tubers and annual aerial parts, glabrous or partly pubescent (not in East Africa)
- Tubers globose to irregularly shaped; flesh white, yellow, pink or purplish red; growing points one or more, protected by a neck of sheathing fibrous remains of leaf-bases
- Leaves 1-5, appearing with or after the flowers, erect to prostrate; blade linear to broadly ovate (sometimes circular or with enations in southern Africa), often with a distinct petiole-like base
- 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
- 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
- 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
- Ovary superior, sessile, with 3 locules, each with 2-6 axile ovules; style terete; stigma apical, small
- Fruit a loculicidal capsule, turbinate to ovoid
- Seeds oval to comma-shaped, densely covered with hairs, silvery white when fresh, turning brown with age
According to Flora of West Tropical Africa under the synonym Agavaceae[FWTA]
Agavaceae, F.N. Hepper. Flora of West Tropical Africa 3:1. 1968
- Rootstock a rhizome; stem short or well developed
- Leaves usually crowded on or at the base of the stem often thick and fleshy, entire or with prickly teeth on the margin
- Flowers bisexual, polygamous or dioecious, racemose to paniculate or subcapitate, sometimes in a very large thyrse, bracteate
- Perianth segments free or united; corona never present
- Stamens 6, inserted at the base of the lobes or on the tube; filaments filiform or thickened, free; anthers introrse, 2-locular, opening lengthwise
- Ovary superior or inferior, often beaked, 3-locular, with axile placentas; style slender Ovules numerous and superposed in two series to solitary
- Fruit a capsule or berry
- Seeds with fleshy endosperm
According to Flora of Tropical East Africa under the synonym Dracaenaceae[FTEA]
Dracenaceae, Geoffrey Mwachala & Paul Mbugua, Flora of Tropical East Africa. 2007
- Trees, shrubs or herbs
- Leaves alternate, rosulate, distichous or spirally arranged, sometimes in pseudo-whorls, sessile, the base often (semi-)amplexicaul, succulent or not; primary venation parallel
- Inflorescence usually a terminal panicle, occasionally appearing racemose by reduction of primary branches; pedicel of a peg-like basal part crowned by a distinct joint, and an obconical receptacle, persistent in fruit
- Flowers in irregular clusters, 1–several per cluster, subsessile, with a bract subtending each flower, fragrant, nocturnal; perianth tubular, with 6 spreading or recurving lobes
- Stamens 6, inserted in the throat, with inflated or filiform filaments; anthers dorsifixed, versatile, opening by lateral slits
- Ovary superior, free, globose, 3-celled; ovules erect, solitary in each of the three chambers; style filiform; stigma capitate
- Fruit a berry, 1–3-seeded
- Seeds rounded, bony, white.
