Aloe ruspoliana<br />
Description<br />
The species grows in Bamboo (Oxytenanthera abyssinica)<br />
thicket with open rocky outcrops or partially<br />
covered by slanting rocks giving them protection during<br />
fire season between 1490 <strong>and</strong> 1500 m close to Assosa in<br />
Wellega floristic region. The general area where it grows<br />
experiences natural <strong>and</strong> man made fire regimes. The main<br />
flowering period is between April <strong>and</strong> August.<br />
13. Aloe ruspoliana Baker<br />
The specific epithet ‘ruspoliana’, refers to a Roman prince<br />
[“Principe Romano”], Count Eugenio Ruspoli. He was<br />
the leader <strong>of</strong> an expedition in 1893 together with another<br />
Italian, Dr. Domenico Riva, to Southern <strong>Ethiopia</strong>. The<br />
type <strong>of</strong> the species was designated from one <strong>of</strong> Ruspoli’s<br />
collections, <strong>and</strong> the species was named in honour <strong>of</strong> him.<br />
According to a note written by J. B. Gillett in the Kew<br />
Library, Ruspoli was killed by an elephant near the Sagan<br />
River in the Gamo G<strong>of</strong>a floristic region on 4 Dec. 1893.<br />
The species was described in 1898. The type material was<br />
collected between Mil mil <strong>and</strong> Imi in Harerge Region.<br />
The species is one <strong>of</strong> the two Aloe species (along with<br />
A. retrospiciens) whose leaves smell strongly <strong>of</strong> mice<br />
when freshly cut <strong>and</strong> whose flowers are bright yellow.<br />
It is a very distinct species, easily recognised by the s<strong>of</strong>t<br />
yellow green leaves with minute marginal teeth.<br />
Rosettes stemless or with decumbent or ascending stems to 50 cm<br />
long, suckering to form groups, <strong>of</strong>ten quite large. Leaves ca. 16, 37–<br />
60 × 7.6–12 cm, suberect to spreading, very s<strong>of</strong>t, pale yellowishgreen,<br />
sometimes obscurely pale spotted, not canaliculate. Marginal<br />
teeth 0.3–0.7 mm long, 14–30(–60) per 10 cm. Inflorescence long<br />
pedunculate, 1.2–2 m high with 12 or more racemes. Racemes 2 4<br />
cm long, subcapitate. Bracts c. 3 × 1.5 mm. Pedicels 5 mm long.<br />
Perianth cylindrictrigonous, 13–16 mm long, 4–5 mm wide when<br />
pressed, yellow; outer lobes free for 5–6 mm.
