Habitat <strong>and</strong><br />

distribution<br />

Gladiolus murielae<br />

Description<br />

The species is the most distinctive <strong>of</strong> the indigenous<br />

species by its short inflorescences much shorter than the<br />

long droo ping leaves, by the relatively small pale mauve<br />

perianth, <strong>and</strong> by the short dark­violet stamens borne at<br />

the mouth <strong>of</strong> the perianth tube.<br />

Plant (8–)12–28 cm high. Corm 8–10 mm in diameter, with tunics <strong>of</strong><br />

fine-netted fibres. Leaves 2–4, lowermost longest, 1.5–2.5 times as<br />

long as stem, blades linear, (2–)3–4 mm wide, uppermost smallest<br />

<strong>and</strong> with oblong blades or largely to entirely sheathing. Stem erect<br />

below, flexed outward above sheath <strong>of</strong> uppermost leaf, un branched.<br />

Spike (1–)2–3-flowered; bracts green, 15–30(–35) mm long,<br />

usually attenuate, inner about two­third as long as outer. Flowers<br />

bluish­purple (mauve), tepals evidently unmarked; perianth tube<br />

narrowly funnel­shaped, c. 18 mm long; tepals lanceolate, unequal,<br />

dorsal <strong>and</strong> upper laterals c. 18 mm long, 3 lower c. 20 mm long.<br />

Filaments short, c. 6 mm long, included in tube; anthers c. 5 mm<br />

long, dark­violet, apices drawn into short acute appendages. Ovary<br />

oblong, c. 4 mm long; style arching over anthers, dividing at or 1–2<br />

mm beyond anther apices, branches c. 2.5 mm long. Capsules <strong>and</strong><br />

seeds unknown.<br />

The species grows on steep rocky slopes <strong>and</strong> cliffs,<br />

between 2100 <strong>and</strong> 2750 m, in areas originally forested,<br />

but today largely cleared. It is only known from Gara<br />

Muleta in Harerge floristic region. The main flowering<br />

period is from August to October.<br />

15. Gladiolus murielae Kelway<br />

The specific epithet ‘murielae’ is named in honour <strong>of</strong><br />

Muriel Erskine, the wife <strong>of</strong> the collector.<br />

The species was described by Kelway in 1932 from a<br />

plant collected from <strong>Ethiopia</strong> without precise locality by<br />

Erskine.The species is also known (<strong>and</strong> cultivated) under<br />

the name Acid an thera bicolor.<br />

Gladiolus murielae, G. c<strong>and</strong>idus, <strong>and</strong> G. gunnisii are<br />

the only three species in <strong>Ethiopia</strong> with a perianth tube<br />

twice as long as the tepals. G. murielae is distinguished<br />

from the others by the white flo wers with prominent dark<br />

purple streaks <strong>and</strong> tepals 35–45 mm long.<br />

Plant 30–65 cm high. Corm 15–22 mm in diameter. Foliage leaves<br />

4–8, lower 3–5 basal, narrowly lanceolate, reaching at least to base<br />

<strong>of</strong> spike, sometimes slightly exceeding it, 5–12 mm at widest. Stem<br />

unbranched, 3–4 mm in diameter at base <strong>of</strong> spike. Spike <strong>of</strong>ten<br />

inclined, 3–5-flowered. Flowers white, with a prominent dark purple<br />

median streak, sweetly scented, particularly strongly in evenings;
