The present study was conducted to provide a check list of angiosperms
for plant conservation.
diversification using small and large phylogenetic trees.
Hypothesis: Vessel grouping is a form of xeromorphy that is present in angiosperm
woods that do not have tracheids as am imperforate tracheary element type.
Relations of environmental change to angiosperm

Recently, a number of species in various genera of the angiosperms
have been observed to have bordered pit pairs possessing an impermeable torus as well as a surrounding margo with openings the size of the pit membrane of typical angiosperms
rather than the larger openings of the margos of gymnosperms.

Results showed that the phylogenetic tree more consistent with the evolution of Viridiplantae proposed by the Angiosperm
Phylogeny Group (APGII) classification system and additionally supported by the bootstrap was obtained with the combination of rpoC1 and matK markers, using the neighbor joining method and applying a Tamura-Nei distance-correction (Figure 1).
