182 AMARYLLIDACEAE Description Habitat and distribution Notes Leaves, 30–50 × 1–3.5 cm, glabrous. Scape 18–20 cm long, glabrous; inflorescence (1–)2–3-flowered, subtended by a membranaceous entire bract, sometimes with an apical split. Pedicels 1–2.5 cm long. Perianth tube 1–2 cm long; free tepal segments 3–5.5 cm long, 0.5– 0.8 cm wide, pure white, spreading; corona reduced to 12 triangular teeth, i.e. two teeth between each of the 6 stamens, each tooth up to 5 mm long. Filaments c. 2 mm long, about 1 cm long, style slightly over topping the anthers at anthesis. Capsules 3.5–4 cm long and 1.2 cm wide, carrying the persistent perianth tube at the apex. Seeds black, several, globose, 4–5 mm in diameter. It grows in open Combretum-Terminalia bushland at 1370 m, and is so far only known from the wild near Assosa in Welle ga. It has otherwise been collected a few times in Chad (in cultivation), Cameroon and the Central African Republic. The flowering pe riod in Ethiopia is from May to June. The species has, as indicated above, a very short perianth tube compared to the other species in the genus. This might indicate that the pollinators are smaller hawkmoths with a relatively short proboscis. The rarity of the species indicates that it is vulnerable.
Distribution and classification Reproduction HYACINTHACEAE SCHIZOBASIS DIPCADI 183 The family includes bulbous plants with leaves, often more or less spotted, filiform to lanceolate, in a basal rosette. The scape is glabrous and leafless. The inflorescence is usually a raceme or a spike, rarely extremely branched (as in Schizobasis). The flowers are white to greenish, yellowish, or purplish, often with a darker green or purple midrib. The tepals are free or fused into a shorter or longer tube. The ovaries include one to many ovules per locule. The fruit is most often a loculicidal capsule, that means it splits between the walls separating its three chambers, rarely it is septicidal, i.e. it splits along the separating walls. The seeds are black, subglobose or flattened, sometimes winged. Hyacinthaceae is related to the Alliaceae (the onion family), differing mainly in chemistry and inflorescence, which is umbellike in the latter. The sulphur compounds giving the particular smell and taste of members of the onion family are lacking in the hyacinths. Amaryllidaceae is also related, sharing the features of a typical bulb, the basal leaf rosette and the glabrous scape, differing in the umbel-like inflorescence similar to the onions; and further by the inferior ovary. The family is widely distributed in tropical to temperate areas worldwide. Its centres of diversity are in Southern Africa and in the Mediterranean area. Taxonomists today disagree on the generic delimitation; from 40 to 67 genera are recently reported. On species number the agreement is better, and c. 900 species are accepted. On the Horn of Africa there are 7 genera: Schizobasis, Dipcadi, Drimiopsis, Ledebouria, Drimia, Albuca, and Ornithogalum. All these genera have centres of variation in southern Africa. Dipcadi, Drimia, and Ornithogalum reach the Mediterranean region and Central Asia. The species from the Horn of African find their closest relatives in the south. Pollen and nectar are offered as floral rewards. The nectar is produced in the septal walls of the ovary, and secreted
