Descriptions
Asphodelaceae, Christopher Whitehouse. Flora of Tropical East Africa. 2002
- Morphology General Habit
- Perennial rhizomatous herbs usually containing anthraquinones thatcolour the rhizome and roots yellowish inside; roots fibrous, sometimes swollen or occasionally with tubers
- Morphology Leaves
- Leaves in a basal rosette, or rarely distichous, rarely on a short woody stem, lanceolate to linear or terete
- Morphology Reproductive morphology Inflorescences
- Inflorescence simple or paniculate; pedicels solitary and subtended by a single bract, not articulated or articulated at the apex Peduncle mostly naked, occasionally a few sterile bracts below the inflorescence
- Morphology Reproductive morphology Flowers
- Flowers bisexual, hypogynous; tepals 3+3, free or fused
- Morphology Reproductive morphology Flowers Androecium
- Stamens 3+3, free or slightly fused to the perianth; filaments filiform; anthers dorsifixed, ± versatile, dehiscing longitudinally introrsely
- Morphology Reproductive morphology Flowers Gynoecium
- Ovary 3-locular, with 2–several ovules per locule; placentation axile; style slender with a small stigma
- Morphology Reproductive morphology Fruits
- Fruit a loculicidal capsule
- Morphology Reproductive morphology Seeds
- Seeds enveloped by a dull brown or greyish black aril
Asphodelaceae, S. Kativu. Flora Zambesiaca 12:3. 2001
- Morphology General Habit
- Perennial herbs, often herbaceous geophytes perennating by rhizomes, acaulescent, rarely caulescent; rhizome often yellow when cut, sometimes pinkish
- Morphology Roots
- Roots fibrous, sometimes swollen or fusiform
- Morphology Leaves
- Leaves in a basal rosette, or sometimes ± distichous on a short woody stem; lamina linear, flat to ± terete
- Morphology Reproductive morphology Inflorescences
- Inflorescences terminal or lateral, pedunculate with flowers racemosely or paniculately arranged; peduncle (scape) erect, leafless, occasionally with 1–3 sterile bracts below the inflorescence; pedicels subtended by a bract, non-articulated, or articulated at the apex
- Morphology Reproductive morphology Flowers
- Flowers bisexual, 3-merous, actinomorphic; perianth petaloid, segments (tepals) of 3 inner and 3 outer, free or fused, white or pink, greenish- or pale yellow, yellow or red
- Morphology Reproductive morphology Flowers Androecium
- Stamens of 3 inner and 3 outer, free or slightly fused to the perianth; filaments filiform, glabrous, scabrid or hairy; anthers dorsifixed, ± versatile, longitudinally introrse dehiscent
- Morphology Reproductive morphology Flowers Gynoecium
- Ovary superior, 3-locular with axile placentation; ovules 2–many per locule; style slender with a small stigma
- Morphology Reproductive morphology Fruits
- Fruit a capsule with loculicidal dehiscence
- Morphology Reproductive morphology Seeds
- Seeds dull brown or greyish-black, sometimes arillate
- Chemistry
- Anthraquinones present in some taxa, giving the rhizome and sometimes the roots a yellowish colour inside
Hemerocallidaceae, C. Zimudzi & G. V. Pope. Flora Zambesiaca 12:3. 2001
- Morphology General Habit
- Perennial herbs or subshrubs, glabrous, rhizomatous
- Morphology Leaves
- Leaves distichous, sometimes with bases overlapping (equitant), clustered or evenly spaced on the stem, ovate to linear, sheathing at the base or not; lamina ± flattened throughout, or folded together lengthwise in the lower part and opened out in the upper part
- Morphology Reproductive morphology Inflorescences
- Inflorescence terminal, paniculiform or of a solitary flower
- Morphology Reproductive morphology Flowers
- Flowers hypogynous or perigynous, actinomorphic or zygomorphic, usually articulated on pedicels
- Morphology Reproductive morphology Flowers Perianth
- Perianth wholly or partially marcescent; tepals 6, free or shortly united into a tube
- Morphology Reproductive morphology Flowers Androecium
- Stamens 6, all free and hypogynous or inserted on tepal bases, or all connate at the base with 3 hypogynous and 3 inserted on tepal bases; anther filaments ornamented or not; anthers basifixed or dorsifixed, dehiscing latrorsely by pores or slits Pollen trichotomosulcate (sulcate in Hemerocallis)
- Morphology Reproductive morphology Flowers Gynoecium
- Ovary syncarpous, 3- or 1-locular; style simple, terminating in a small capitate stigma or tuft of short hairs; ovules anatropous on axile or parietal placentas, bitegmic, 1–numerous on each placenta
- Morphology Reproductive morphology Fruits
- Fruit a berry or capsule; seeds black, exarillate
Aloaceae, S. Kativu. Flora Zambesiaca 12:3. 2001
- Morphology General Habit
- Herbs, shrubs, or trees, often with thickened roots
- Morphology Leaves
- Leaves usually perennial, fleshy, sheathing at the base and occasionally forming an underground bulb, in rosettes or spirally arranged, sometimes distichous, linear to lanceolate or ovate to triangular-conical; the margins with spine-tipped teeth or entire and sometimes ciliate; lamina smooth, rough or warty
- Morphology Reproductive morphology Inflorescences
- Inflorescences pedunculate with flowers in 1–several terminal and axillary racemes, simple or paniculately arranged; bracts scarious, often sterile below the racemes, sometimes leaf-like on the lower part of the peduncle
- Morphology Reproductive morphology Flowers
- Flowers bisexual, 3-merous, often zygomorphic, pedicellate, red, orange, yellow, white, or green, often bird-pollinated; perianth-segments 6, fused in the lower part to form a tube, the lobes in 2 whorls; stamens 6, inserted at the base of the ovary; ovary superior, 3-locular; style simple
- Morphology Reproductive morphology Fruits
- Capsule dehiscing loculicidally
- Morphology Reproductive morphology Seeds
- Seeds several to numerous in each locule, often winged
