| description | Recent studies on Schismatoglottideae have
resulted in the recognition of four new monophyletic
genera, the resurrection of two additional genera following
clarification of their monophyly, and the publication of
many taxonomically novel species. However, generic
boundaries among some parts of Schismatoglottideae
remain unclear owing to several reasons: (1) more taxa are
being revealed through our on-going fieldwork, now
expanded to previously unsampled localities on Borneo;
(2) established occurrence of a high level of homoplasies
among the morphological characteristics hitherto used to
delimitate genera; and (3) gene regions used in previous
studies contradicted some of current taxonomic placements.
Among the unsolved groups from previous studies a
clade comprising Schismatoglottis sarikeensis and S. josefii
needs further investigation. Therefore, phylogenetic analyses
were carried out to investigate the position of these
two species using the nuclear region, internal transcribed
spacer and combined plastid regions: trnL intron and trnLF
intergenic spacer, coding matK?partial 30 trnK, intergenic
spacer trnH-psbA. A total of 23 accessions representing
16 taxa of Schismatoglottideae and Philonotieae
were included in the study. Phylogenetic analyses of a total
4,658 bp combined dataset using parsimony, maximum
likelihood, and Bayesian methods revealed that S. sarikeensis
and S. josefii do not belong to Schismatoglottis, and therefore are transferred to Schottarum (:Hottarum sarikeense
: Schismatoglottis sarikeense). Flowering mechanism,
pollination strategy, and fruitset of S. sarikeense are
also presented in the paper. |
