280 DRACAENACEAE Subspecies key Dracaena ombet subsp. ombet Habitat and distribution Dracaena ombet subsp. schizantha Description Habitat and distribution in the middle. Perianth white, 6 mm long including the 0.5 mm long tube. Ovary oblong; stigma shallowly 31obed. Fruits orange, globose, usually 1seeded, 1 cm in diameter. Seed globose, 6 mm in diameter. 1. Leaf margin smooth; end branches of the inflorescence glabrous. a. subsp. ombet - Leaf margin scabrid; end branches of the inflorescence pubescent. b. subsp. schizantha a. subsp. ombet Tree up to 4 m tall. Leaves without a keel, crescentshaped in cross section; margins smooth; basal part only twice as wide as long. Inflorescence glabrous throughout. This subspecies differs from subsp. schizantha by the glabrous inflorescence. The subspecies grows in open Olea europaea forest on limestone, and in semidesert grassland whith scattered Acacia scrub, in Tigray and Afar floristic regions in Ethiopia, and along the Red Sea coast of Eritrea, between 800 and 2100 m. It also occurs in Egypt and the Sudan. Fruiting specimens have been collected in October. b. subsp. schizantha (Baker) Bos The subspecific epithet ‘schizantha’ refers to the deeply divided (schiz-) flowers (-anthus). The subspecies was descri bed as Dra cae na schizantha by Baker in 1877 from a plant collected from the Ahl and Serut mountains in Somalia by Hil de brandt. The species was later reduced to subspecies by Bos in 1997. It differs from the related subspecies, subsp. ombet by having pubescent inflorescences (mainly towards the tip). Tree up to 8m tall, old bark becoming very smooth, gray. Leaves generally narrow with a keel and rather triangular in cross section, margin distinctly scabrid, blade widened abruptly to a clasping base, 3–4 times as wide as long. Inflorescence with smaller branches minutely pubescent. The subspecies grows in mountain slopes, in Acacia- Commiphora bushland on limestone, and also in evergreen bushland do mi nated by Buxus and Acokanthera between 1000 and 1800 m in Sidamo, Bale, and Harerge floristic regions. It also occurs in Somalia, and possibly in Yemen. The main flowering period is from February to May.
Fig. 123. Dracaena ombet subsp. ombet from Tigray floristic region. Dracaena steudneri Description 5. Dracaena steudneri Engl. DRACAENA 281 The specific epithet ‘steudneri’ was given in honour of the German collector, Steud ner, who collected the type spe cimen from Gonder floristic region. The species was described by Eng ler in 1895. It differs from the related species, D. ellenbeckiana and D. afromontana by the ripe fruits being purplish maroon. In contrast, D. ellenbeckiana and D. afro mon tana have orange ripe fruits. Shrub to tall tree up to 15(–25) m tall, trunk 20–45 cm in diameter, with leaf scars remaining visible. Leaves leathery, shiny, bright to dark green, swordshaped, up to 130 × 16 cm, base clasping, narrowing to 2–6 cm at 5–10 cm from the base, blade widest around the middle, upper part gradually tapering towards the acute tip,
