    Distribution
    Endemic to the Philippines; Luzon, Mindanao, Polillo. Although Engler cited a specimen (now destroyed) from Sulawesi in the protologue of a. warburgii, no other material from Sulawesi is conspecific with the Philippines element.
    Habitat
    Lowland rain forest (dipterocarp forest) to ca. 300 m altitude.
    General Description
    Small herb to ca. 40 cm tall; stem to ca. 20 cm long, decumbent to creeping, ca. 1.7 cm thick; leaves 3-4 together; petiole to ca. 35 cm long, sheathing in the lower ca. Quarter to third; blade to ca. 27 cm long, narrowly (hasto-) sagittate, sometimes shallowly to deeply peltate in adult plants and then some non-peltate leaves also present; anterior lobe to 20 cm long, to ca. 10 cm wide at base, narrowly triangular, with the margin sometimes shallowly sinuate; anterior costa not very prominent abaxially, with 3-4 sometimes opposite primary lateral veins diverging at ca. 45-60° and usually distally deflected towards the leaf tip, then joining a cospicuous submarginal vein situated ca. 3 mm from the margin; secondary venation rather widely spaced (ca. 3 mm) arising from the primary at a high angle, thence mostly abruptly (ca. Right angle) deflected towards the margin and forming rather disorganised interprimary collective veins; glands in the axils of primary vains inconspicuous; posterior lobes diverging at an acute angle, narrow, tapering, sometimes distally out-turned; posterior costae naked in sinus for ca. 1.2 cm to pelatate for ca. 20% of their length; inflorescences paired, to 4 together; peduncle to ca. 4 cm diam., ca, half the length of the patioles; spathe 5-6.5 cm long; lower spathe narrowly ovoid, 2.5-3 cm long, differentiated from the limb by a rather long gradual constriction; limb narrowly lanceolate, eventually reflexed; spadix ca. Three quarters of the length of the spathe, shortly stipitate, with the stipe adnate to the spathe; female zone 0.5-1 cm long, containing few to several flask-shaped pistils; style ca. 0.5 mm, stigma globose; sterile interstice ca. 5 mm long, comprised of massive synandrodia filling the upper part of the cavity of the lower spathe; male zone ca. 5-8 mm long, subcyclindric, ca. 3 mm thick; synandriamore or less hexagonal, ca. 1.2 mm diam., opening by apical pores not capped by synconnective; appendix ca. 2 cm long, tapering; infructescence ovoid, ca. 3 cm diam.
