Abstract Detail


Onagraceae as a model experimental system

Raven, Peter [1].

My Life with the Evening Primroses.

My studies of Onagraceae began in 1956 under the influence of Harlan Lewis, and they eventually led me all over the world and through all the subdisciplines of botany, joyous excursions that have introduced me to many wonderful colleagues and taught me much about plant evolution. The family, as part of the order Myrtales, probably originated in West Gondwanaland, or in the part of that continental mass that became South America,and it has spread over nearly all habitats suitable for plants subsequently. Outbursts of speciation occurred in Andean South America (Fuchsia), New Zealand (Epilobium), and especially in the western United States (tribe Onagreae). Anatomy, embryology, vegetative and floral morphology, palynology, cytology, allozymes, nucleicacids, reproductive biology, and many other lines of evidence have helped us clarify relationships within the family over the past 55 years. I have had a remarkable and fulfilling journey that has filled my life with joy, interest, and friends throughout the world.
