It was first described by the English botanist John Bellenden Ker Gawler in 1812. DescriptionTacca integrifolia is a herb growing from a thick, cylindrical rhizome. The leaf blades are borne on long stems and are oblong-elliptical to oblong-lanceolate, some {{convert|50|by|20|cm|in|0|abbr=on}}, with tapering bases and slender pointed tips. The flower scape is about {{convert|55|cm|in|0|abbr=on}} long and is topped with a pair of involucral bracts, broad and erect, white with mauve venation. Among the individual nodding flowers, which are arranged in an umbel, are further long, filiform (thread-like) bracts. The perianth of each flower is tubular and purplish-black, {{convert|1|to|2|cm|in|1|abbr=on}} long, with two whorls of three perianth lobes, the outer three narrowly oblong and the inner three broadly obovate. The fruits are fleshy berries some {{convert|2|cm|in|1|abbr=on}} long, and the seeds, which have six longitudinal ridges, have the remains of the perianth lobes still attached.[2][3]Distribution and habitatThe species is native to hilly regions of tropical and subtropical central Asia. It is known from Pakistan, eastern India, Sri Lanka, Bhutan, Bangladesh, Nepal, Myanmar, Malaysia, Thailand, Cambodia, Vietnam and eastern China.[2] It grows in the understorey of humid rainforests, growing in the leaf litter in shady sites.[4] EcologyThe stamens are attached to the tube of the perianth in a helmet-like manner and, with the flat-topped stigma lobes, may form an insect trap; a sweet musky odour has been detected from these flowers and this may attract flies as pollinators. After pollination, the scape bends over and the developing fruits rest on the ground. The fleshy fruits are a dull colour with soft jelly-like pulp, and it is possible that the seeds are dispersed by rodents and other small mammals as they feed on the fruits.[3] References1. ^{{ThePlantList|id=kew-267844|taxon=Tacca integrifolia||authority=Ker Gawl.|accessdate= 17 June 2017}} 2. ^1 {{cite book|author=Wiart, Christophe |title=Medicinal Plants of the Asia-Pacific: Drugs for the Future? |url=https://books.google.com/books?id=-t_ICgAAQBAJ&pg=PA688 |year=2006|publisher=World Scientific |isbn=978-981-4480-33-8 |pages=688–689}} 3. ^1 {{cite book|author=Klaus Kubitzki|title=Flowering Plants.
