The Pinnatae; comprising six families of woody plants with pinnately compound leaves, is represented on the Florida Keys by at least 16 species. The taxonomic treatment of these families at the ordinal level has been inconsistent. The purpose of this study is to correlate the data derived from intensive study of the xylem anatomy of these 16 species with data from the literature concerning these and other members of the families involved, so that new insight might be gained concerning the taxonomic relationships among these families. This study indicates that the members of the Pinnatae are anatomically homogeneous. All members possess simple perforation plates, vessel elements having alternate intervascular pitting, fibrous elements with small slitlike simple to vestigially bordered pits, and apotracheal and paratracheal axial parenchyma, or both. Secretory structures, such as crystalliferous idioblasts, parenchymatous cells containing 'gum'; and intercellular canals, are of wide occurrence within the Pinnatae. In addition, many species possess septate fibers and axial parenchyma arranged in aggregate patterns, with banded arrangements being most frequent. There is no anatomical basis for the separation of families into distinct orders in my view. The only separation of families within the Pinnatae suggested by a syndrome of several unique characters, in addition to those common to all members, is the formation of an Anacardiaceae-Burseraceae complex. The members of the Pinnatae belong to a taxon corresponding well with Cronquist's Sapindales. Phylogenetically, the Pinnatae constitutes an advanced taxon, based on xylem anatomy.

This book is the first comprehensive guide to Florida's amazing variety of tree species: from scrub oak on the high central ridges to mangroves stretching along the southern coasts, from mighty live oaks to the delicate and diminutive hawthornes, from bald cypress with their knees poking up from the swamps to the coppery-colored gumbo limbo found in tropical hammocks of the Everglades and Keys, from the sabal palm found all over the state to the rare and endangered yew found only along the banks of the Apalachicola River in northern Florida. Florida, unique among the states, has both tropical and temperate forests. The early Florida visitor was awed by miles of unending pine flatwoods. Most modern Florida visitors are amazed by the lush tropical trees planted in cities, suburbs, and public gardens. This book covers both natives and exotics and includes suggested field sites for observing the species described. Divided into two sections, this book serves as both a reference and a field guide. Both sections help the reader answer the question “What tree is that?" by focusing on the families of Florida's trees. The line drawings show a combination of typical leaves, fruits, and flowers, and while accurate in detail, capture an overall impression, so helpful when trying to identify a species in the field. The color photos, all taken in Florida, are useful where color is important in identification. The first edition was very popular with both professionals and laypeople alike—it was heralded as accurate, comprehensive, and organized and written in an easy-to-understand way. This edition will be even more useful, as it adds about 140 more tree accounts for a total of more than 480 species. There are almost 600 color photos and many drawings and range maps. And now included is a key to tree families that will help with field identification.

From Sassafras to Dandelions to Wild Onions and Garlic, readers will enjoy the flavors of the Sunshine State in an all new way with this helpful book. Florida is filled with an abundance of native plants with roots, stems, leaves, flowers, fruit, and seeds that can provide tasty and nutritious food for people. Salads, teas, soups, and even breads can be made from flora that grows wild and can be foraged throughout the year. This guide offers identification tips, recipes, and other useful information for foragers interested in venturing out to sample the bounty of the land. Clear pen-and-ink illustrations aid in identification of leaf, fruit, and root shapes—key to harvesting the delicious and interesting plants that can be found throughout the state.

Florida ranks third in the U.S. in the number of plants about 4,000 species that cover its landscape. Here at last is an easy-to-use field guide to them all, chock-full of line drawings and color photos. This book will be useful to professional botanists, landscape architects, and homeowners alike.
