    [FTEA]

    Dracenaceae, Geoffrey Mwachala & Paul Mbugua, Flora of Tropical East Africa. 2007

    Inflorescences
    Protologue states: “nearly allied to {i}D. ombet{/i}. Panicle glabrous; pedicels densely clustered, 2–3 mm; perianth cylindrical, 12 mm; tube half as long as the segments; stamens as long as the perianth; style distinctly exserted”
    Note
    The type consists of a (partial?) inflorescence some 22 cm long and unbranched. It looks like it might be a branch of something bigger. There are little clusters of pedicels subtended by triangular bracts 1.2–2 mm long and acute; the pedicels are 1–2 mm long. In the envelope attached to the sheet there is a flower with a tube 5.5 mm long and lobes 8.3 mm long and ± 1.5 mm wide; the style is 17 mm long. There are no other parts present. Only known from the type. The material is not enough to decide the specimen’s generic identity. From the degree of exsertion of the stigma, and the appearance of the pedicels, it could be that this material is a partial inflorescence of {i}Sansevieria ehrenbergii {/i}Schweinf.

    Inflorescences
    Inflorescence paniculately branched in the upper three-quarters of its length, (0.9–)2–3 m long, inflorescence stalk 0.6–1.1 cm thick, branches up to 3–4 from the same point i.e. a central major, 2 large and a smaller one, 5–7 cm apart; inflorescence stalk wavy, ascending, the lower branched, the upper simple; long bract 1.1–1.5 cm long, subtends each branch; flowers 4–5(–7) per cluster, clusters numerous, 1.4–1.8 cm apart, arranged in a spiral; bracteoles 0.1–0.2 cm long; pedicels 0.3–0.4 cm long, jointed above the middle.
    Flowers
    Flowers greyish purple, 1.1–1.3 cm long, tube 0.5–0.6 cm long, lobes linear, (0.3–)0.5–0.9 cm long, obtuse; style 1.4 cm long, thin; filament ± 1 long, anthers 0.2 cm long, yellowish
    Fruits
    Fruit a berry, yellowish green when ripe

    Distribution
    Sudan, Ethiopia, Djibouti, Somalia.Also in Yemen & Oman.
    Ecology
    Dry wooded grassland, dry bushland, thickets, often on rock or termite hills, also in coastal bushland or drier types of evergreen bushland; may be locally common, can withstand heavy grazing pressure; 0–1900 m
    Conservation
    Least concern
    Note
    Clusters more prominent than in {i}S. robusta {/i}and closer together. This species has leaves more upright than in {i}S. robusta{/i}.
