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

distribution<br />

Chlorophytum<br />

cameronii<br />

Description<br />

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

distribution<br />

stiffly erect above the arcuation, scabrid to pubescent, leafless,<br />

10–15 cm long. Inflorescence a simple raceme, rachis scabrid, <strong>of</strong>ten<br />

sinuate (‘zig zag’). Flowers single at each node; pedicels stiffly erect,<br />

up to 7 mm long, articulated near the base. Tepals patent, white<br />

with greenish brown stripe on the outside, 8–9 mm long, 3­veined.<br />

Capsule erect, triquetrous, slightly transversely ridged, c. 5 × 7 mm,<br />

emar ginate, with remnants <strong>of</strong> the perianth at the base. Seeds thin,<br />

folded, ca. 3 mm across.<br />

It grows in Acacia-Commiphora bushl<strong>and</strong> or wooded<br />

grassl<strong>and</strong>, on shallow soils <strong>of</strong>ten overlying limestone<br />

between 950 <strong>and</strong> 1450 m. It is recorded from the Sidamo<br />

<strong>and</strong> Bale floristic regions in <strong>Ethiopia</strong>, but is otherwise<br />

widespread in tro pical Africa from Senegal in west to<br />

Zambia in south. The main flowering period is from<br />

October to November.<br />

19. Chlorophytum cameronii (Baker) Kativu<br />

The species epithet honours the collector <strong>of</strong> the type<br />

material, Cameron, who was the first to collect the<br />

plant, in Tanzania. It was described by Baker in the<br />

genus Anthericum in 1876, <strong>and</strong> later transferred to<br />

Chlorophytum by Kativu in 1993. This is an elegant<br />

lily with large showy flowers, up to 3 cm in diameter,<br />

which are white inside <strong>and</strong> pinkish outside. It is further<br />

characterized by the ‘zigzag’ inflorescence <strong>and</strong> winged<br />

peduncle.<br />

Plants tufted, 40–70 cm high. Rhizome short, knobby, horizontal,<br />

moniliform; roots thin, wiry, bearing distinct distant tubers. Leaves<br />

subdistichous to distichous, linear to linear lanceolate, sheathing<br />

below, glabrous, 30–70 × 0.6–0.9 cm; midribs prominent. Cataphylls<br />

<strong>and</strong> outer leaf bases with reddish brown spots or stripes. Peduncle<br />

flat, narrowly winged, glabrous, up to 40 cm long. Inflorescence<br />

unbranched, up to 16 cm long; rachis sinuate (‘zigzag’), winged<br />

below, terete above, glabrous. Pedicels 1–4 at each node, articulated<br />

be low the middle, up to 8 mm long in fruit. Tepals 10–15 mm long,<br />

(3–)5–7 veined, whitish, outer ones pinkish on the outside. Stamens<br />

slightly shorter than the perianth, arranged in two groups, 4 in the<br />

upper <strong>and</strong> 2 in the lower; filaments glabrous, as long as the anthers.<br />

Style declinate, slightly exserted. Capsule obovoid, trigonous,<br />

transversely ridged, up to 7 mm long. Seeds irregularly folded, ca.<br />

1 mm in diameter.<br />

This species grows in Combretum-Termi nalia woodl<strong>and</strong><br />

with tall grasses on s<strong>and</strong>y soils, between 500 <strong>and</strong> 600 m.<br />

It is rather rare in <strong>Ethiopia</strong>, only found a few places in the
