Abstract
Plants in central China often identified as Tricyrtis latifolia are distinct from that species in many characteristics: the perianth is nearly horizontally patent at the level of 1/3 from the base (obliquely ascending in T. latifolia); the anthers are much longer than those of T. latifolia; the inner tepals are narrowly trullate at the base (auriculate in T. latifolia); the roots contain orange anthraquinoid pigments; the leaves are pubescent on both surfaces (glabrous on both surfaces or somewhat pubescent only in the undersurface in T. latifolia). We therefore describe the central Chinese plants as a new species, T. pseudolatifolia, which we assigned to section Tricyrtis, to which T. latifolia belongs.
