Thysananthus ( Lejeuneaceae , Marchantiophyta) Phytotaxa 193 (1) © 2015 Magnolia Press • 29 camp along track to Malakuna, van Zanten 68–2435/b (JE).— WESTERN: Kolombangara Island, Braithwaite 4429 (JE).

Taxonomic notes:— Thysananthus convolutus is morphologically very similar to T. gottschei but differs from the latter by toothed leaves and underleaves (entire in T. gottschei ) and triangular perianth teeth, which are 1–2 cells long (laciniate perianth teeth, 2–4 cells long in T. gottschei ).

The original material in the Nees herbarium (STR) contains 5 specimens. Four are Thysananthus convolutus and only one has the mention “ Υ ”. Since “ Υ ” was cited by Lindenberg in the protologue of T. convolutus , I have chosen the “ Υ ” material as the lectotype also because it provides the best match with the protologue. No type material of T. convolutus was found in the Lindenberg herbarium (W) or in herbarium Leiden (L). Although there is no collector cited, the material is from the same locality as T. spathulistipus , as mentioned in the protologue. I, therefore, assume that the material was collected by Blume. Molecular analysis has resolved T. convolutus as polyphyletic ( Sukkharak et al. 2011b).
