| Comments |
The plant is named after Mount Lawit in the Bentaung-Karimun
National Park. Other than a comment that the species resembles M.
muluensis he authors do not comment on the sectional status of this plant. It
is, however, an Australimusa although this section has been absorbed into the Callimusa by
Wong et al 2002. According to Nasution and Supardiyono M. lawitiensis
differs from M. muluensis in i) having distinctly long and proportionately
slender fruits and ii) having the free tepal the same length as the compound tepal.
M.
suratii is very similar to M. lawitiensis. If they are sufficiently
similar to be considered synonymous then M. lawitiensis has priority.
