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

Morphology General Habit
Frutescent, grows in thick stands, rhizomes subterranean; stem upright, terete, 1–1.5 m high, 2–2.5 cm in diameter, no aerial branching; node (1.5–)2–2.5 cm long, distinct, greenish light grey to brown on exposed portions, only the basal part exposed, the upper completely ensheathed by leaves
Morphology Leaves
Leaves very spreading and recurving, 17–25(–35) per plant, flat to U-shaped, narrowly lanceolate to broadly linear-lanceolate, 27–32 cm long, 2–4.5(–6) cm wide, thick at the base, acute, spiral, slightly twisted especially the older leaves, smooth; spine 0.4–0.7 cm long, stout, horny, pale brown and more or less spotted; margins less than 0.5 mm wide, very narrow, pale brownish, with a greyish brown membrane that widens basally to almost 0.4(–0.5) cm wide
Morphology Reproductive morphology Inflorescences
Inflorescence a terminal panicle, 55 cm high, ± 20–23 cm wide; peduncle 0.4–0.6 cm thick; branches 10–11(–15) cm long, basal branches with 3–5 secondary branchlets 4–6(–8) cm long; each branch and branchlet subtended by a bract 0.7–1.7 cm long, with a sharp spine; lower inflorescence bracts 1–2, lanceolate, 5.5–9 cm long, greenish grey but upper ones greyish brown (on drying), acute, with a sharp spine 0.5–0.6 cm long, greyish brown; flowers (2–)3(–4) per cluster, jointed at base; bracteoles 0.3 cm long, 0.2 cm wide, decreasing up the inflorescence; pedicel 0.2(–0.3) cm long
Morphology Reproductive morphology Flowers
Flowers fugacious, whole perianth 1.2–1.4(–1.6) cm long, 0.1–0.2 cm wide; tube 0.4–0.6 cm long; lobes 0.5–0.6 cm long; style 1–1.3 cm long; filament 0.6–0.7 cm long, exserted, anthers 0.2 cm long; stigma globose
Morphology Reproductive morphology Fruits
Fruit 1–3 per cluster, a globose orange berry, green when unripe.
Distribution
Not known elsewhere
Ecology
Evergreen coastal forest or evergreen bushland; may be locally common; 0–600 m
Conservation
Least concern
Note
This is one of the species that has been mixed with {i}S. bagamoyensis {/i}and even {i}S. powellii {/i}for many years. This came about probablly because as N.E. Brown stated, he never saw a whole specimen of {i}S. bagamoyensis{/i}, while it was very difficult to tell apart the specimens of {i}S. powellii{/i}, especially when dry. {i}S. arborescens {/i}with its spirally arranged, straight and rather high numbers of leaves per plant, with a transverse section of the leaf in an open U-shape, differs from {i}S. bagamoyensis {/i}in that the latter has more leathery, flat light greenish (-yellowish) and generally larger leaves. At the juvenile stage the latter has distichous leaves which may become spiral towards the inflorescence (personal field observations). {i}S. bagamoyensis {/i}also grows under thickets and forms more open stands than {i}S. arborescens {/i}that grows even in the open and in very close stands. The distinction between all the above as far as inflorescence sizes are concerned is not yet quite clear - more material is needed for these to be studied in detail. {i}S. bagamoyensis {/i}has leaves growing sideways and slightly backwards-curved while in {i}S. arborescens {/i}they grow sideways and slightly upwards. {i}S. powellii {/i}N.E.Br. has more fibre content and the leaf is larger compared to {i}S. arborescens{/i}. When {i}S. powellii {/i}dries, the leaves shrink from side towards the centre forming grooves, while {i}S. arborescens {/i}is narrower and the grooves are hardly noticeable. {i}S. powellii {/i}is also very stiff and appears unbreakable while {i}S. arborescens {/i}is flexible and usually more green, narrower and without a very pronounced green colour, narrowed and without very pronounced middle point of the leaf.
