White batflower (Tacca integrifolia)
Description
Tacca integrifolia, the white batflower, is a species of flowering plant in the yam family, Dioscoreaceae, native to tropical and subtropical rainforests of Central Asia. It was first described by the English botanist John Bellenden Ker Gawler in 1812.Tacca 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 50 by 20 cm (20 by 8 in), with tapering bases and slender pointed tips. The flower scape is about 55 cm (22 in) 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, 1 to 2 cm (0.4 to 0.8 in) 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 2 cm (0.8 in) long, and the seeds, which have six longitudinal ridges, have the remains of the perianth lobes still attached.
