viscaceae การใช้

• Modern treatments of the Santalaceae include the family Viscaceae ( mistletoes ), previously considered distinct.
• Most of the Viscaceae bear evergreen leaves that photosynthesise effectively, and photosynthesis proceeds within their green, fleshy stems as well.
• Furthermore, it indicates disagreements about Santalaceae which need to include Viscaceae to be monophyletic ( as is done in APG III ).
• However, the circumscription by APG is much wider than accepted by previous classifications, including the plants earlier treated in families Eremolepidaceae and Viscaceae.
• Traditionally, the genus has been placed in the family Viscaceae, but recent genetic research acknowledged by the Angiosperm Phylogeny Group shows this family to be correctly placed within a larger circumscription of the sandalwood family, Santalaceae.
• Originally, the Loranthaceae contained all mistletoe species, but the typical Christmas mistletoes of Europe and North America, whose genera " Viscum " and " Phoradendron ", belong to the family Santalaceae ( previously, these two genera and their closest relatives were in a separate family, Viscaceae, which has been merged into Santalaceae ).
