BOT 360F - Families of Vascular Plants



Amborellaceae - Amborella trichopoda Baill. - Photo provided by the Missouri Botanical Garden at the XVI International Botanical Congress, St. Louis, August 1999.

The New Caledonian monotypic genus Amborella (Magnoliales: Amborellaceae) was identified as the most primitive living angiosperm the study of phytochrome gene duplications by Mathews & Donoghue (1999), the 5-gene phylogeny published by Qiu et al. (1999), and in the 3-gene phylogeny published by Soltis et al. (1999). Note, however, that the primitiveness of Amborella was identified as early as 1975 because of its wood anatomy (Sporne 1975).
