Dracaena bicolor
Monocaulescent shrubs, probably occasionally forked, exceptionally exceeding 2 m in height. Stents erect, usually about I cm in diameter, the leaves rather evenly distributed but apparently more congested towards the top. Leaves concolorous, generally oblanceolate, 10-35(55) cm long, (2.5 )4-10(12) cm wide in the distal, obovate part, tip acuminate, subulate mucro up to 5 mm long, the proximal part narrowing into a winged pseudo-petiole 1.5-l0(16) cm long, (2)4-8(11)mm wide at its narrowest part directly above the (0.5)1-2(2.5) cm long sheath, clasping the stem for rather more than its circumference, in herbarium costa absent on the upper surface but indicated by an indented band in the lower part, prominent beneath but often disappearing near the tip, primary parallel venation distinct in herbarium, apparently not able to shrink as much in drying as adjacent tissues, rendering the blade a characteristic gooseflesh-like appearance, secondary venation irregular and transverse, not always distinct. Inflorescence terminal, erect, subcapitate to thyrsoid, 4-12 cm long, with several transitional leaves of intermediate shapes and sizes at its base between the leaves and the triangular 2-4( 5) cm long, often purple tinged, floral bracts subtending the closely packed clusters o" a limited number of flowers each, individual flowers tightly enveloped by about 2 cm long bracts and bracteoles, pedicels jointed, persistent basal part 2 3 mm long. Flowers white, somewhat purple tinged. 25-28 mm long, receptacle indurated, about I mm long, perianth tube 15-16 mm long, lobes distinctly shorter, 9-11 mm long and slightly over 2 mm wide, showing a single median vein, filaments inflated, up to 1 mm in diameter, tip sharply pointed erect or hook-like, about 2 mm shorter than the corresponding perianth lobe, anthers 21 x 1 mm. Ovary narrowly ovoid, 3 x 1-1.5 mm. Style about 0.25 mm in diameter, reaching the top of the perianth or up to 1 mm exserted. Stigma distinctly 3-lobed, 1 mm in diameter. Fruits presumably orange but drying black, globose. 9-12 mm in diameter, persistent indurated receptacle 1.5-2 mm.

Unbranched shrubs, stems straight and leafy, leaves generally oblanceolate, exceptionally up to 0.5 m long. 5-10 cm wide, the proximal part narrowed into an up to I cm wide, winged false petiole, dried leaves show a characteristic goose-flesh like texture due to uneven shrinkage of the tissues, inflorescence terminal, subcapitate to thyrsoid, densely packed with clusters of flowers subtended by predominantly purple, 2 5 cm long bracts, perianth not quite 3 cm long, the tube distinctly longer than the lobes, fruits globose, about 1 cm in diameter.
