Solenostoma truncatum (Nees 1830: 29) R.M. Schust. ex Váňa & D.G.Long (2009: 509) is widely distributed and the commonest Solenostoma-species in south-east Asia, reaching from Himalayas, India and Srí Lanka to China, Japan, Micronesia, Samoa, New Guinea and northern Australia (Queensland).
The species is very variable: its leaf form varies from subquadrate-rotund, ovate, ovate-ligulate to rarely ligulate, the cell texture is also relatively variable, but the marginal leaf-cells are mostly +- equally thickened in 1-2 or more rows, and the cuticle is usually at least minutely verrucose, rarely nearly smooth. Perianth is shortly to longly exserted, fusiform or ovate, perianth mouth is contracted or wide, crenulate, sometimes with ciliate marginal cells.
