Habitat and distribution Aloe debrana The species grows in sparsely vegetated rocky slopes and outcrops between 2100 and 2700 m in Tigray and Gonder regions in Rthiopia and also in Eritrea. It is so far not known anywhere else. The main flowering period is from September to October, so me times also in March to April. 22. Aloe debrana Christian The specific epithet ‘debrana’ refers to the locality (Debre Berhan in the Shewa Region) of the plant on which the description of the species was based. In Amharic language Debre Berhan refers to the ‘place of the light’, debre meaning place and berhan meaning light. The living plant was collected by McLoughlin, cultivated in Pretoria, and the species was described in 1947.
ALOE Fig. 38. Aloe debrana, from top of Blue Nile Gorge, Shewa floristic region. Description Habitat and distribution Notes 79 A. debrana belongs to a group of aloes (numbers 21–22 and 26–27) which often ex hibit secondary branching (up to 50 racemes or more) and which usually are stemless, but some old plants develop thick, prostrate stems. A. debrana is distingui shed from the rest of the group by the small bracts 3–6.5(–8.5) mm long. Succulent herb, suckering from base to form small groups, mostly stemless but some old plants develop thick, prostrate stems. Leaves in a very dense rosette, spreadingrecurved, 25–60 × 7.5–15 cm, dull green, old leaves brown when drying. Marginal teeth 7–10 (–14) per 10 cm, 2–4 mm long, with red tips. Inflorescence ca. 100 cm long, compoundly branched; racemes 8–50. Racemes capitate to cylindrical, 5–15 cm long, lax or dense (4–9 flowers per cm). Bracts ovatetriangular, 3–6.5(–8.5) × 1.5–3 mm, scarious. Pedicels 10–15(–17 in fruit) mm long. Perianth cylindrical, 17–30 × 4–6 mm when pressed; outer lobes free for 5–10 mm. The species commonly grows in areas of grassland on thin soil overlying basalt, usually on gentle slopes between 2000 and 2700 m in Shewa, Gojam and Welo floristic re gions. It is so far not known anywhere else. The main flowering period is in the dry season, from December to February. There are two forms of the species. The first form has relatively small perianths (18–22 mm long) and bracts (3–5 mm long), while the second has larger perianths
