    Distribution
    Somalia and Masai region: from Kenya (Massai highland) to southwest Somalia and to southeast Ethiopia
    General Description
    Tuber very flat globose, 6-15 x 3-8 cm, red brown to grey white. LEAF apearing after the flower, up to 1 m high. Petiole 30-50 cm long or more, red to green and mottled green and white. Blade up to 1 m in diameter; terminal leaflets elliptic to inversely egg-shaped, 3-12 x 1-3 cm, attenuating in a 0.5 cm long tip. Cataphylls 2; 2-20 x 1,5-3 cm, the inner one more than 20 cm long and pink with black markings, the outer one brown and membranous. Peduncle smooth, 20-45 x 0.8-2.5 cm, a weak olive green to brownish with white spots and black markings, appearing before the leaf, basally sometimes with adventitious roots. INFLORESCENCE: Spathe 16-40 cm long; divided by a slight constriction into an elongate-cylindrical to ovoid (‘oval’) tube and a long, narrow, triangular, open limb. Tube 6-13 x 3-9 cm; outside greenish, purple to brownish or olive to green, with white spots; inside basally brownish to purple, with strongly branching, barely raised, longish ribs, which extend upward for 4-5 cm, then a greenish, smooth zone at the transition to the open limb. Open limb 10-27 x 8-15 cm; long triangular; sometimes somewhat twisted; attenuating in a small tip; outside green, purple to brownish or olive to green, with white spots; inside purple to brown; margin strongly undulate. Spadix sessile, emerging from the axis at an angle, 30-70 cm long, 1½ to twice as long as the spathe. Pistillate zone cylindrical, 1.7-4 x 1.5-2 cm, flowers partly congested. Staminate zone long obconical to cylindrical, 2.5-4 x 0.8-2.3 cm, flowers may be distant [and] in groups of 3-5 stamens, but generaly [flowers] congested. Appendix long conical; 25-80 x 1.3-1.7 cm (base); ± smooth, or rough due to narrow, inconspicuous longitudinal ribs; reddish to brown or purple to green; without clear constriction basally. Staminodes absent; sterile zone between pistillate and staminate zone absent; ratio of pistillate to staminate zone 0.6-0.8 : 1. Pistillate flowers 4-5 mm long, tilted upwards; ovary globose to ovoid, 2-2.5 x 1.5-2 mm, unilocular, placentation basal, green and apically becoming brownish; style 2-3 mm long, abruptly emerging from the ovary, somewhat bent towards the axis, dark purple to brown, sometimes dotted pink; stigma plurimorphic, 0.5-0.7 x 0.5-0.7 mm, somewhat zygomorphic, subapical (‘seitlich am Griffel sitzend’), stigmas unlobed button-shaped to triangular or bi- to tri-humped, white to green. Staminate flowers 1-1.75 x 1-2 mm; anthers free, cubical, 1 x 1 mm, greenish to cream; connective dark brown to purple; filaments 0.2-0.5 mm long, 3-5 together forming a platform-like “Columna”, these can be clearly delimited groups in larger inflorescences, otherwise congested; pores apical, circular to broadly elliptic (‘oval’), one pore per theca visible. Pollen inaperturate, 30-50 x 25-41 µm, ovoid, cream, exine striate. Smell very unpleasant. INFRUCTESCENCE: Not known.
    Habitat
    Frequent in dry Bushsavannas, open woodlands, degraded bushlands. Less frequent on rocks (Inselbergs?) and in river source regions (‘Quellgebieten’).
    Diagnostic
    Amorphophallus gallaensis is a conspicuous species from Kenya and the southern regions of Ethiopia and Somalia. A. gallaensis stands out by its chocolate coloured (purple-brown to reddish-brown) spathe and the similarly coloured appendix
    Phenology
    Flowers from October until December.
