    Amorphophallus barthlottii is one of the smallest species in the genus and certainly the smallest of the African species. It was erroneously identified as A. staudtii (Engl.) N.E. Br. by Barthlott & Bogner (1981). A. barhlottii belongs to a group of species with a limited distribution in the very humid part of Liberia and the Ivory Coast. It has to be placed into the large African section with hairlike emergences at the base of the spathe tube, and is similar to A. johnsonii, A. calabaricus, A. zenkeri and A. staudtii. Basal inner side of the spathe with hair-like emergences; Spathe with a slight constriction, and tube vase-shaped; spathe limb margin broad and laterally to horizontally erect; staminate zone cylindrical.

    General Description
    Tuber globose or subglobose, 2-4 x 1.5-3 cm, surface whitish, probably not developing offsets. LEAF unknown. INFLORESCENCE: Cataphylls 3, 4-13 cm long, membranous, whitish to green with a touch of pink, the inner one longer than the peduncle. Inflorescence short-peduncled, appearing before the leaf; peduncle 5-9 cm long, half of it subterranean, 1.5-3 mm in diameter, smooth. Spathe erect, forming a conical bag 7-9 cm long and 3.5-4 cm in diameter, tube and limb separated by a shallow constriction; tube oblong-triangular in lateral view, 3.5-5.5 x 2.5-3.5 cm, cross section shape circular, outside whitish to dirty pinkish or greenish, inside purple to purplish brown, with very short (0.4-0.9 mm) loosely dispersed hairlike emergences, surface between emergences rough to papillose, unicoloured dark purple, veins somewhat raised: limb erect. 3-4 cm long, triangular-acute, inside and outside whitish to dirty pinkish, margin smooth to undulate and flushed with purple. Spadix stipitate for 1-3 cm. 8-13 cm long, slightly longer than spathe (1 : 0.7-0.9): pistillate zone cylindrical, l-l .5 cm long, 4-5 mm in diameter, flowers congested or slightly distant: staminate, one cylindrical. 1.3-2 mm long. 2.5-3.5 mm in diameter, flowers congested; appendix elongate-conical, acute. 5-9 cm long, base without constriction, equal in diameter to the staminate zone, surface rough to rugulose: ratio of pistillate to staminate zone length 0.7-0.8: staminodes absent; without sterile zone between staminate and pistillate zone. Staminate flowers l- l .5 mm long, with 2-4 stamens; filaments only 0.5 mm long, free; anthers free, elongate to ovoid; thecae ovoid, yellow, each with one apical circular pore. Pistillate flowers 3-3.5 mm long; ovaries globose to ovoid, 2 mm long and wide, green or greenish white, bilocular; stigma sessile, slightly 2-lobed. 1.5-2 mm in diameter. 1 mm long, circular in cross section. Pollen globular, inaperturate. c. 50 mm in diameter, exine smooth (psilate). INFRUCTESCENCE: unknown.
