52 ALOACEAE 49. Leaves strongly recurved, impossible to dry flat, marginal teeth 5—6 per 10 cm of leaf margin; pedicels 12—17 mm long 35. A. megalacantha - Leaves only slightly recurved, relatively easy to dry flat, marginal teeth 7—12 per 10 cm of leaf margin; pedicels 9—10 mm long 36. A. gilbertii Description Subspecies 1. Aloe trichosantha Berger The specific epithet ‘trichosantha’ refers to the hairy (trichos-) flowers (anthos). The species was described by Berger in 1905. The type material was collected in the Ghin da valley between Asmera and Mitsiwa (Massawa) in Eritrea. This species belongs to a small group of Ethiopian/ Eritrean aloes (numbers 1–6) with pubescent or papillate flowers, a group to which A. vera might be related. The group includes: A. trichosantha, A. pubes cens, A. citrina, A. bertemariae, A. eumas sa wana, and A. schoelleri. A. trichosantha is distinguished from the other species in the group by its sharply reflexed bracts. Like A. bertemariae it has relatively short pedicels, only up to 8 mm long. A. bertemariae has leaves inrolled, spotted and with spines on the lower parts. Rosettes stemless, solitary or suckering to form groups. Leaves 12–20 per rosette, 25–70 × 2.5–13.5 cm, suberect with slightly incurved tips, slightly canaliculate, dull grey green without spots in adult plants, juveniles densely pale spotted. Marginal teeth 4–12 per 10 cm, 2 5 mm long with brown tip. Inflorescence up to 2 m high, erect, with 1–3(–4) racemes. Racemes 40–70 cm long, cylindricalconical, dense (2–3 flowers per cm). Bracts lanceolate, 10–19(–23) × 4–8 mm, finely pubescent, sharply reflexed after flowering. Pedicels 2.5–8(–11 in fruit) mm long. Perianth cylindricaltrigonous, curved slightly upwards towards tip, 20–30 mm long, 4.5–6.5(–7) mm wide when pressed, pale to bright pink with short, sometimes dense, white indumentum; outer lobes free for 6–9 mm. Capsule 19–23 × 7.5–8 mm. Seeds 3angled, 4.5–6 mm long, brown to almost black with pale spots and narrow pale wings. The species is subdivided into two subspecies based on the density and length of the teeth along the leaf margin and the length of the flower. The differences between the subspecies are small, but consistent enough to justify subspecific rank. In our present knowledge, there is a wide gap between the distribution areas of the two subspecies. Thus the species should be looked for in this
