A. afzelii has elongated, leathery leave blades that can be up to 35 cm long and 13 cm wide. The leaf stems are generally shorter than the blade. The leaves are set on a creeping and rooting rhizome that is 1-4 cm thick. The spathe is 3-7 cm long (exceptionally up to 9 cm long) and has a 13-32 cm long peduncle. The spadix is 5-8 cm long (exceptionally up to 12 cm long) and slightly longer than the spathe, so that the tip slightly protrudes from it.
