We propose a method for seed shape quantification based on the comparison of the bi-dimensional images of the seeds with geometric figures. J index is the percent of similarity of a seed image with a figure taken as a model. Models in shape quantification include geometrical figures (circle, ellipse, oval ::: ) and their derivatives, as well as other figures obtained as geometric representations of algebraic equations. The analysis is based on three sources: Published work, images available on the Internet, and seeds collected or stored in our collections. Some of the models here described are applied for the first time in seed morphology, like the superellipses, a group of bidimensional figures that represent well seed shape in species of the Calamoideae and Phoenix canariensis Hort. ex Chabaud.

Corresponding author: Peter Wilf (e-mail: [email protected]) 1 https://mc06.manuscriptcentral.com/botany-pubs Botany Page 2 of 36 Abstract: The cycads pose classic problems in evolutionary biogeography due to their far-flung extant distributions and the sparse fossil records of living genera. A noteworthy example is Tribe Encephalarteae of Family Zamiaceae, today consisting of Encephalartos (Africa) and the Australian genera Lepidozamia and Macrozamia . Numerous petrified trunks of Encephalarteae described from the Cretaceous of Patagonia, Antarctica, and India indicate far larger past distributions across Gondwana and subsequent extinctions. The only fossils close to the current range are Paleogene leaf fragments from Australia assigned to Lepidozamia and Macrozamia . Here, we report a large frond piece and several isolated leaflets of a compressed cycad, along with an associated spiny petiole, from the late-Gondwanan, 52.2 Ma Laguna del Hunco flora of Patagonia, Argentina.

  • Ecology of Native Oil-Producing Palms and Their Potential for Biofuel Production in Southwestern Amazonia
    ECOLOGY OF NATIVE OIL-PRODUCING PALMS AND THEIR POTENTIAL FOR BIOFUEL PRODUCTION IN SOUTHWESTERN AMAZONIA By JOANNA MARIE TUCKER LIMA A DISSERTATION PRESENTED TO THE GRADUATE SCHOOL OF THE UNIVERSITY OF FLORIDA IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY UNIVERSITY OF FLORIDA 2010 1 © 2010 Joanna Marie Tucker Lima 2 To my parents who taught me to appreciate and marvel at the natural world. 3 ACKNOWLEDGMENTS This work is the culmination of a long journey and the encouragement and support of many people throughout my academic career. As this chapter of my life comes to a close, I wish to extend special thanks to my PhD advisor, Karen Kainer, who was a continuous and consistent inspiration and source of encouragement to me. Her expertise and insight enriched my research from beginning to end. I also thank Evandro Ferreira for his contagious love for palms and mix of practical and scientific advice. His students, Janice and Anelena, as well as the research team at the Parque Zoobotanico at UFAC, especially Plinio, Lira, and Edir, were always willing to help with field work and logistics, for which I am very grateful. Anelise Regiane and her chemistry students at UFAC (Thayna, Nubia and Marcia) gave unselfishly of their time to help me process palm fruits and run chemical analysis that I could never have done alone. I am indebted to Francis “Jack” Putz for sharing his curiosity for the natural world and his persistent search for answers to both basic and complex ecological issues that affect our daily lives.

Allagoptera caudescens is a monoecious palm with a solitary stem usually 12 to 24 feet tall in habitat, but the stem can also be short or subterranean. The fronds are pinnate with an extremely short petiole. These palms are native to lowland tropical rainforest along the coast of Brazil at elevation of up to 1,000 feet. They are reported to persist in cleared areas which indicate they will tolerate full sun exposure. I have three specimens planted in the shade in an area which is prone to flooding during heavy rain. Dale Holton and Ruth Sallenbach also have their palms planted in the shade.
