Dracaena fragrans (L.) Ker-Gawl.
Taken From:Bos JJ. 1984Habit:Single stemmed shrubs to branched trees, 1½–15 m or even more tall, main trunk may surpass 30 cm in diameter. Seedlings produce orange roots, juvenile leaves ovate, acute, lacking the constriction above the sheathing base.Leaves:Leaves lorate-oblanceolate, the widest part distinctly above the middle, (30–)40–125(–150) cm x (3–)4–10(–12) cm, tip acute with a subulate mucro up to 4(–8) mm long, narrowly cuneate towards the base, narrowest part (8–)10–35(–43) mm wide few cm above the sheathing base enveloping the supporting stem; bright green and lacking a midrib above, paler beneath, midrib usually prominent for three quarters of its length, parallel nervature distinct in herbarium secundary venation if visible, irregularly transverse; variegation as shown in several horticultural clones has not yet been recorded in West African collections.Inflorescence:Inflorescence a branched terminal panicle, erect, inclined or bend over and pendulous with a zigzag main axis, (30–)40–100(–160) cm long with up to 22 to ½ m long branches, 30–15 cm long, transitional leaves on the peduncle may form a series rapidly decreasing in size with the bracts subtending the inflorescence branches, flowers arranged in usually multiflowered stalked or sessile spherical glomerules evenly distributed over branches and the unbranched apex of the main axis, with 2 glomerules on each side of the base of the larger branches, in large inflorescences such lateral glomerules usually stalked at the lowest branches; the flowers accompanied by broadly triangular white scarious bracts up to 3(–5) mm long, usually slightly shorter than the 2–5 mm long persistent pedicels.Flowers:Flowers white, often with fine red lines down the centre of each lobe outside, (15–)18–22(–25) mm long, receptacle obconical, indurated, 1½–3 mm, perianth tube (5–)8–10(–l 1) mm long, shorter than the (8–)9–11 (–12) mm long lobes, these up to 3 mm wide with a single central vein, stamens inserted at the throat, filaments inflated, up to ¾ mm in diameter, tip subulate, 1–3 mm shorter than the corresponding perianth lobe, anthers 2–2½ mm x 1 mm, ovary cylindrical to bottle-shaped, 2–3(–4) mm x 1½-2 mm, style terete, ¼ mm in diameter, stigma 3-lobed, 1 mm across, 1–3 mm exserted.Fruits/Seeds:Fruits bright orange, depressed globose, 11–18 mm long, 13–19 mm in diameter, lobed when more seeded, with a persistent up to 5 mm long receptacle. Seeds white, turning brown when exposed, with a brown patch enveloping the raphe, rounded-rectangular to bean-shaped, 10–14 mm x 8–9 mm x 5–7 mm.Dracaena fragrans (L.) Ker-Gawl.
Taken From:Mwachala G, Mbugua PK. 2007Habit:Shrub or tree, 1.5–15 m high; stem single, up to 30 cm in diameter, or in forest often with a mass of horizontal stems near the ground from which vertical stems arise.Leaves:Leaves strap-shaped to oblanceolate, sessile, (7–)20–150 cm long, 2–12 cm wide, base attenuate, widening for 2–5 cm and sheathing the stem, apex acute with subulate mucro.Inflorescence:Inflorescence erect, rarely pendent, paniculate, 15–160 cm long; flowers in multiflowered glomerules; pedicels 2–6 mm long, articulated below the middle.Flowers:Buds purple or pink, flowers with tube white, the lobes white with a fine red to purple line down the centre, darker outside, (15–)17–22(–25) mm long, tube 5–11 mm long, lobes 7–12 mm long, up to 3 mm wide.Fruits/Seeds:Fruits bright orange, depressed globose, 11–19 mm in diameter, lobed when several-seeded; seeds white
