description: Chlorophytum mamillatum Elden & Nordal, sp. nov. (Fig. 5)   
 Species nova C. gallabatensi affinis, sed eo differt tuberibus secus axem radicis non in ramis lateralibus dispositis; inflorescentiis laxis prostratis; floribus albis non viridibus; testis periclinalibus cellularum mamillatis.   
 A species related to C. gallabatense, differing by having root tubers along the root axis, rather than on lateral branches; lax, prostrate inflorescences, not stiffly erect; white flowers, not greenish; and nipple-like projections on the periclinal seed cell walls.   
 Type: — ETHIOPIA. Bale floristic region: 10 km N of Dolo Menna (Masslo) on the road to Goba, 6º25’ N 39º44’E, 1500 m of elevation, 25 October 1984, I. Friis, M. G. Gilbert & K. Vollesen 3459 (holotype ETH!; isotype K!).   
Perennial with short rhizome, roots ca. 2 mm in diameter, with distal tubers, 20–40 × 5–10 mm. Leaves rosulate, strapshaped, 150–600 × 15–30 mm, glabrous with narrow hyaline margin. Inflorescence paniculiform, length (including peduncle) 250–500 mm with 2–7 branches. Bract supporting branches up to 12 mm long, usually shorter; bracts supporting flower nodes up to 3 mm long, with dark brown margin. Number of flowers per node 1–3(4). Pedicel length 3–5(–7) mm, with a joint disposed from the middle to upper part, slightly papillose below the joint (at least in fresh material). Flowers star-shaped, white with greenish apex; tepals free, lanceolate, 4–5 × 1.5–2 mm; filaments filiform, 2–3 mm long, slightly papillose, white; anthers 1–2 mm long, yellow; style 4–5 mm long, bent with a minute stigma. Capsule triangular in cross section, papillose, ca. 4 × 6 mm; seeds 3 or 4 per locule, diameter 2 mm, flat and irregularly folded, periclinal walls of epidermal cells conical and outdrawn to a distinct papilla (Fig. 4).  
 Distribution: — The Bale and Harerge floristic regions, Ethiopia (Fig. 2B).
