An Updated Phylogenetic Classification Of The Flowering Plants, Robert F. Thorne
Aliso: A Journal of Systematic and Floristic Botany
This update of my classification of the flowering plants, or Angiospermae, is based upon about 800 pertinent books, monographs, and other botanical papers published since my last synopsis appeared in the Nordic Journal of Science in 1983. Also I have narrowed my family- and ordinal-gap concepts to bring acceptance of family and ordinal limits more in line with those of current taxonomists. This new information and the shift in my phylogenetic philosophy have caused significant changes in my interpretation of relationships and numbers and content of taxa. Also the ending "-anae" has been accepted for superorders in place in the …

Endemism In The Vascular Flora Of The Juan Fernandez Islands, Tod F. Stuessy, Clodomiro Marticorena, Roberto Rodriguez R., Daniel J. Crawford, Mario Silva O.
Aliso: A Journal of Systematic and Floristic Botany
The Juan Fernandez archipelago contains 361 vascular plant species including 53 ferns, 65 monocots, and 243 dicots. Represented are 73 families and 219 genera. There is one endemic family (Lactoridaceae), 12 endemic genera, and 126 endemic species. The native vascular flora has II% endemism at the generic level and 60% at the specific level. Among the endemic species, 23 are ferns, 15 are monocots, and 88 are dicots. Of the endemic dicots, 29 species are Compositae, making up 33% of the endemic dicot flora. Most (97%) of the endemic angiosperms are perennials, and 64% of the dicots are woody (shrubs, …
