    Diagnostic
    Based on the great similarity of Amorphophallus consimilis and A. baumannii, this species was formerly put under A. flavovirens (= A. baumannii). Hepper (1968) was not convinced that the morphological characters were sufficient to recognise A. consimilis as a separate species. Owing to the size variation of the spathe, he saw A. consimilis as a form (within the range of variation) of A. flavovirens. If one considers this trait on its own, that conclusion is understandable. In principle however, with the significant size variations within a species one needs to consider if there are any geographical or other correlations. Especially so, in a group that strongly tends towards endemism and is still in the process of colonising new habitats. Be that as it may, more important than a geographical correlation is in this case the correlation of the spathe size with other morphological differences (see also A. gracilior). The most important are: 1. the exine of the pollen of A. consimilis is spinose, 2. the ovary is unilocular and 3. the staminate zone is cylindrical (further differences see species description). According to this, A. gracilior is the closest relative or A. consimilis. A. baumannii is only distantly related. A. baumannii shows clear affinity to the A. johnsonii . Style barely visible or absent, ovary unilocular, appendix conical to cylindrical.
    Habitat
    In lowland on humid to marshy soils.
    Distribution
    Western Guineo-Cogolese region reaching into the south western zone of the Guineo-Congolese-Sudanese transition zone: Gambia and Senegal
    General Description
    Tuber flat globose, 4-7 x 2-4 cm, irregularly circular from above, surface rough to scaly. LEAF appearing after the inflorescence, 60-80 cm high. Petiole 25-50 cm long, 0.5-1 cm in diameter, with purple spots. Blade 30-45 cm in diameter, mostly only divided into 2nd order leaflets; rachis only winged distally; terminal leaflets inversely egg-shaped, 7-12 x 3-5 cm, gradually tapering into a short point which is 0.5-1 cm long; margin smooth or slightly serrate. Cataphylls 2, the inner most 8-11 cm long, translucent pink with light-purple longitudinal stripes. INFLORESCENCE appearing before the leaf, 30-52 cm high. Peduncle 22-45 cm long, 0.5-1 cm in diameter; basally light-purple, further up brown-red with green mottling. Spathe 5-11 cm long; divided by a slight constriction into a narrow, vase-shaped tube and a narrow, triangular-acute, open limb. Tube 2.5-5 x 1.5-4 cm; cylindrical to vase-shaped; outside dirty greenish to whitish with greenish spots; inside basally usually smooth, basally with a light-brownish to purple or light-purple 0.5-1 cm high zone, with slightly raised veins and very small dark-purple dots, rarely with few, small and loosely dispersed tongue-like emergences, these < 0.5 mm long. Open limb erect, 2-6 cm long, narrowly tapering and triangular-acute, otherwise enclosing the tube; outside dirty-greenish to whitish, with greyish spots; inside dirty whitish beige; margin smooth to slightly undulate. Spadix sessile, 8-20 cm long, about 1-1.5 times as long as the spathe. Pistillate zone cylindrical, rarely slightly conical, 0.5-0.8 x 0.7-0.9 cm, flowers congested, forming at least 3 spirals. Staminate zone cylindrical, 1.5-3 x 0.5-1 cm, flowers very densely congested. Appendix cylindrical to conical, 6-12 cm long, basally 0.5-1 cm in diameter, basally without constriction, apically acute; surface with flat, longitudinal furrows that are close together and make the surface appear rough to rugulose; brown, brown-red or purple. Sterile zone between staminate and pistillate zone absent; staminodes absent; ratio of pistillate to staminate zone 0.23-0.37 : 1. Pistillate flowers 2.5-3 mm long; ovary egg-shaped, 1.5-2 x 1 mm, unilocular, very rarely incompletely bilocular, one basal ovule-attachment, light-green; stigma sessile, 0.5 x 0.5 mm, globose, not lobed, rarely with two small humps, whitish to brownish. Staminate flowers 1-1.3 x 1-1.3 mm; anthers free, cuboid to ovoid, greyish to purple, ca. 3 per flower; filament not visible or < 0.5 mm long; pores broadly elliptic (‘oval’) , apical or slightly lateral, one pore per theca; connective broadly grooved, purple-brown. Pollen bright orange, inaperturate, 33-46 x 30-46 µm, globose to slightly ovoid, exine echinate. INFRUCTESCENCE somewhat elongating, 30-40 cm long; peduncle of infructescence 15-30 cm long, 0.2-1 cm in diameter, very thin; infructescence-head globose to ovoid, 3-4 x 2.5-3 cm, often with remains of the spathe. Berries single seeded, ovoid to cylindrical, 1 x 0.5 cm, with stigma remains, light-orange red depending on maturity. Seeds ovoid to flattened ovoid, 0.8-0.4 cm, smooth-ribbed. Smell not known.
    Phenology
    Flowers in May.
