New Year, New Family Names

Happy 2011! The latest Oregon Flora Newsletter just arrived, and I was pleased to see the Oregon Flora Project is ready to adopt the latest family classifications from the Angiosperm Phylogeny Group (APG). “What is the APG?,” you may be wondering. When I first started pestering the professional botanists around me with questions about who decides what the proper botanical name for a plant is, I was surprised that there didn’t seem to be some governing body making those kinds of decisions. An individual could do research on a plant, decide it should be reclassified, and it was up to others whether they felt the research warranted adopting this new name or classification. So botanical names could be almost as localized as common names.

Fringed grass-of Parnassus (Parnassia fimbriata) is now considered to be a member of Celastraceae. We'll have to wait and see if it stays there as it has proven a difficult genus to classify.

According to the Wikipedia article, “The Angiosperm Phylogeny Group, or APG, refers to an informal international group of systematic botanists who came together to try to establish a consensus view of the taxonomy of flowering plants (angiosperms) that would reflect new knowledge about their relationships based upon phylogenetic studies.” At last, a single source for plant classification! It seems that most plant authorities are now following the APG classifications, so we can expect more consensus in the future. With all the new genetic-based research bringing so much new information to light, it is a relief to have some central body overseeing classification. Read the rest of this entry »
