Three aspects of the study, which were</p><p>morphological, anatomical and phytochemical, were carried out to determine</p><p>significant taxonomic characters. The data obtained were then used to construct</p><p>taxonomic keys for genera and species involved. A total of 22 species were collected</p><p>from several forest reserves in Malaysia. Samples were prepared for herbarium</p><p>vouchers, anatomical study, and phytochemical procedures. Morphological characters</p><p>were observed and recorded. Anatomical slides of leaf were prepared using standard</p><p>microtechnique method, while phytochemical screening was conducted using</p><p>Qualitative Phytochemical Screening and Thin Layer Chromatograph (TLC). All</p><p>characters obtained were numerically analyzed using the Multivariate Statistical</p><p>Package (MVSP) and Phylogeny Analysis Using Parsimony (PAUP). The findings</p><p>showed that some characters have high taxonomic significant value. Leaves margin and</p><p>venation are diagnostic characters in morphological findings. Petiole and midrib</p><p>outline, petiole and midrib vascular bundle, type of stomata, type of trichomes and the</p><p>presence of vascular subsidiaries are the diagnostic characters in anatomical findings.</p><p>In phytochemical study, terpenoids, flavonoids, and alkaloids are present in almost all</p><p>species studied, while saponins are only detected in nine species, namely Congea</p><p>forbesii, Congea griffithiana, Sphenodesme racemosa, Clerodendrum breviflorum,</p><p>Clerodendrum disparifolium, Lantana camara, Stachytarpheta indica, Stachytarpheta</p><p>jamaicensis and Stachytarpheta cayennensis. Numerical analysis showed that two main</p><p>clades were formed at 0.709 and 0.821 of GGSc value to indicate the delineation of the</p><p>two families. Morphological and anatomical findings able to contribute solution to</p><p>taxonomic problem, while phytochemical data provide vital preliminary information of</p><p>the studied species. Finally, it is concluded that all aspects of studies numerically</p><p>support the classification of Li et al., therefore implicates that the findings can serve as</p><p>important taxonomic references to the current classification of the families.</p> 2023 thesis https://ir.upsi.edu.my/detailsg.php?det=12042 https://ir.upsi.edu.my/detailsg.php?det=12042 text zsm N/A openAccess Doctoral Perpustakaan Tuanku Bainun Fakulti Sains dan Matematik <p>Abraham-Oanes, G.
