Preliminary Phylogenetic Study of Bucephalandra (Schismatoglottideae: Araceae)
Tribe Schismatoglottideae is one of the most species-rich and diverse aroids taxa in Borneo, with more than 250 species, of which over 95% are endemic. Schismatoglottideae contains a diverse group of rainforest terrestrial, litophytic or rheophytic herbs centred in Borneo. Bucephalandra (Araceae:...

| Summary: | Tribe Schismatoglottideae is one of the most species-rich and diverse aroids taxa in Borneo, with more than
250 species, of which over 95% are endemic. Schismatoglottideae contains a diverse group of rainforest
terrestrial, litophytic or rheophytic herbs centred in Borneo. Bucephalandra (Araceae: Schismatoglottideae)
is endemic to Borneo and known by its unique staminodes, with the presence of motile scale or shield-shaped
staminodes situated at the interstice of the pistillate and staminate flower zones. Phylogenetic analyses of
Bucephalandra were carried out in this study based on nuclear of Internal Transcribed Spacer (nrITS) and
Megakaryocyte-associated tyrosine kinase (matK). Eight taxa were included in this study which also
comprised the sister tribe, Cryptocoryne longicauda Becc. ex Engl. as the outgroup. Plant specimens were
collected from respective localities. DNA was extracted from leaf samples, PCR amplified and sequenced.
Analyses of both datasets with Maximum Parsimony, Maximum Likelihood and Bayesian Methods were
carried out. Bucephalandra was revealed to comprise two clades. |
