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

Morphology General Habit
Acaulescent herb; rhizome subterranean, 5–9 cm long, 2–3 cm in diameter
Morphology Leaves
Leaves solitary, erect, rigid, cylindric, (0.8–)1.5–2(–3) m long, 2–3 cm thick at the middle, slightly rough, slightly tapering upwards to apex, narrowing to a stout acute whitish hardly prickly point; juvenile with a concave channel 0.4–0.6 cm wide, 0.2–0.4 cm deep on upper surface and almost closed at leaf apex; 4–6 longitudinal impressed lines on the sides and back which deepen into furrows with age, dull green or bluish green, often with a brownish tint and entirely greyish green when mature, slightly subglaucous especially when young, and then marked with numerous closely placed transverse pale green bands which disappear with age; margin in juveniles brownish red to grey-green with a whitish grey membrane on the outer side, the brownish grey margin disappear with age; basal scaly leaves flat, very reduced, ensheathing the solitary cylindrical leaf, 8–10, 6.5–10(–13) × 2.5–3.5 cm, membranous, subulate tip less than 0.1 cm long, very evident parallel veins, translucent membranous grey-white margins (brownish white on live material); 7 back grooves, 3–4 lines in the channel
Morphology Reproductive morphology Inflorescences
Inflorescence lateral, emerges beside the leaf, crowded corymbose-capitate, 8–10 cm long, open crown diameter up to 12–19 cm; flowers appear solitary above, erect; bracteoles 0.4–0.8 cm long, at base of cluster or each flower; base of cluster 0.3 cm thick; pedicels 0.6–0.9 cm long, very loosely jointed at base
Morphology Reproductive morphology Flowers
Flower white sometimes tinged with violet, perianth 2.8–3.5 cm long, 0.2–0.3 cm wide; tube 1.2–1.6 cm long, lobes 0.8–0.9(–1.3) cm long; stamens 1.2–1.4 cm, anthers 0.3 cm; style 2.4–2.6 cm long
Morphology Reproductive morphology Fruits
Fruit a globose berry, 1.3–1.5 cm diameter; seeds 1 × 0.7 cm.
Distribution
Ethiopia, Somalia
Ecology
Dry bushland; may form dense stands; 250–550 m
Conservation
Least concern
Note
The growth habit of this species is quite diagnostic in that it never produces more than one leaf at any one point. The banding, however, is very variable depending on whether it is in the open or in the undergrowth; the undergrowth specimens tend to be taller, narrower and dark green with distinct light grey bands whereas those in the open are shorter, thicker and light green to grey-green without any visible banding. It was observed, however, that some specimens remained banded and deep green even after being grown in full light for over one year. This phenomenon needs further investigation with more material from the wild. The inflorescence is described here for the first time. The syntype collected by {i}Tompson {/i}and said to be from Uganda is actually from Kenya.
