| description | Twenty-eight species from 4 genera of Guttiferae and 2 genera of Hypericaceae from
the 50-ha Plot of Pasoh Forest Reserve (PFR) Negeri Sembilan and several areas in
Peninsular Malaysia were used to investigate the status and relationships within several
genera in Guttiferae and the relationship between Guttiferae and Hypericaceae.
Molecular and morphological data were used to determine the taxonomic status of these
two families. Phylogenetic studies of the Guttiferae and Hypericaceae have so far based
on morphological data only. Molecular phylogenetic studies based on the trnL-trnF
spacer of chloroplast DNA supported the latest classification that Guttiferae and
Hypericaceae are distinct families. The molecular phylogeny also supported the
morphological classification that all Mesua taxa in Peninsular Malaysia to be
transferred back into genus Kayea, except for M forrea. Genus Ploiarium should be
excluded from Guttiferae. Genus Cratoxylum should be retained in Hypericaceae not as subfamily Hypericoidea in Guttiferae. But the molecular phylogeny failed to support
the morphological classification that merge Calophyllum wallichianum var.
wallichianum and C. wallichianum var. incrassatum as varieties of C. wallichianum.
These two varieties should be transferred back as two different species (Calophyllum
wallichianum and C. incrassatum). In general, the sequence data of the trnL-trnF spacer
solved the taxonomic problems within Guttiferae, and between Guttiferae and
Hypericaceae. Further analysis of other molecular markers from different genes or
genomes should be carried out to ascertain the taxonomic status of these two families. A
support of a careful morphological comparison of these families is necessary to give a
better picture of the classification of these families. |
