| description | This study presents a biogeography hypotheses for the Schismaloglottis nervosa complex (Araceae:
Schismatoglottideae) based on plastid (MatK) DNA sequence data. The aim is to provide insight into the floristic
evolution and taxagenesis of the localized endemics in ever-wet and per-humid tropical forests. The
Schismalogloltis nervosa complex comprises fourteen species endemic to several localities in Borneo and West
Malaysia: Kuching (Bau, Matang, Padawan, and Lundu), Serian, Bintulu, Sarikei, Kapit, Miri, Tawau and Perak.
Each species is endemic to specific substrate: shales, limestone, sandstone and granite. Maximum parsimony and
maximum likel ihood analyses were performed with PAUP* 4.0b lOusing PaupUp graphicaf interface. Results
from these analyses revealed that there are three major clades: the North East Borneo (above Lupar Line) clade,
the Rejang clade, and the West Borneo clade (below Lupar Line). The results suggested that evolution was
estimated to have occurred during Tertiary period. The results also indicated that the species have adapted to their own heterogeological and homogeologicallocalities. |
