Diagnostic
A. gilletii is narrowly allied to A. hastifolia Engler. However, it can be easily distinguished by the position of the thecae, form and size of the spathe and by the spathe in anthesis being reflexed (not reflexed in A. hastifolia) . Fruiting specimens are very hard to distinguish from A. hastifolia and A. pynaertii de wild., they can only be distinguished when at least a remnant of the 3 parts of the spadix is left. Sterile specimens of these species cannot be segregated from each other.
Distribution
Distribution: Nigeria, Cameroon, Gabon, Congo, Zaire.
General Description
Rhizome creeping, prostrate and rooting, ± 1/2 cm thick. LEAVES:densely foliated, sometimes producing a ± 20 cm long stolon.Petiole slender, 6-40 cm long, at the base sheathed. Glabrous, half to 2 1/2 x as long as the leaf-blade. Leaf-blade shortly rounded, auriculate, subcordate or hastate at the base, widest below the middle, glabrous or puberulous below, thinly coriaceous or chartaceous. Lobes up to 13 cm long. Middle lobe 7-25 1/2 cm long, 2-13 cm broad, 1.7-2.7 x as long as broad, oblong-elongate, acute-acuminate. Many prominent lateral nerves with 1-3 less prominent nerves between them, some of which unite before the margin, with many slender, transverse veinlets between them. Lateral nerves at the margin anastomosing in 2-3 marginal nerves. INFLORESCENCE: Peduncle glabrous or sparsely puberulous, 0.4-1.5 x as long as the petiole, 5-22 cm long. Spathe oblong-ovate, spreading when flowering, after flowering closing again, subacute or very short acuminate, small (1-3 cm long, 1/2—1 cm wide), green or pinkish white. Spadix shortly stiped, 1 -2 1/2 cm long, ± as long as the spathe. When flowering spadix entirely exserted. male part equalling or up to twice as long as the female part. female flowers scattered, few, less than 20(-30) (14 in type). Pistils subglobose with a short style. Stigma pink, discoid. male flowers with 3-5 stamens, numerous, thick. Thecae ovate-elliptic, placed on the edge of the synandrium. Seeds and berries observed only once (Bogner 720). INFRUCTESCENCE: Berries depressed-globose. Seeds ca 1 mm long, 0.3-0.5 mm broad; 2.3-3 x as long as broad. Dark brown with many whitish spots on them when dried.
Phenology
Flowering from March-November.
Habitat
Ecology: On the banks of, or in water-courses, sometimes completely submerged.
