Aloe monticola<br />

Mostly stemless but eventually developing a stem up to 30 cm long.<br />

Leaves numerous, 40–50 × 8–12 cm, glossy dark­green, sometimes<br />

spotted when young, with a horny layer along the margin which<br />

usually is contiguous between the spines. Marginal spines 8–10 per<br />

10 cm, 4–5 mm long, dark-brown. Inflorescence with 3–8 racemes.<br />

Racemes subcapitate to cylindrical, 4–9(–20) cm, densely flowered.<br />

Bracts ovate, 9.5–15 × 3–6.5 mm, acuminate. Pedicels 11.5–18(–28<br />

in fruit) mm. Perianth cylindrical­trigonous, 22–28 mm long, 4.5–7<br />

mm wide when pressed, bright yellow or red; outer lobes free for<br />

10–15 mm. Capsule 20–25 × 6–9 mm.<br />

The species grows on sparsely vegetated slopes, <strong>of</strong>ten on<br />

limestone, between 1650 <strong>and</strong> 2100 m in Harerge floristic<br />

region. It is so far not known anywhere else. The main<br />

flowering period is in the rainy season from April to May,<br />

sometimes also from September to October.<br />

20. Aloe monticola Reynolds<br />

The specific epithet ‘monticola’ refers to the habitat <strong>of</strong> the<br />

species: mountain (mon ti­) dweller (­cola). The species<br />

was described in 1957 from type material collected near<br />

Maychew in Tigray floristic region.<br />

A. monticola <strong>and</strong> the previous species, A. harlana,<br />

belong to a group <strong>of</strong> aloes (numbers 19 & 20) which have<br />

a brownish cartilagenous tissue along the leaf margins,<br />

usually forming a continuous edge between the spines,<br />

<strong>and</strong> a bright yellow to red perianth. A. monticola is<br />

distingished from A. harlana by the larger bracts (20–22<br />
