This nomenclatural, taxonomic, and ecological treatment of 11 Central American obligate ant-acacias (Acacia allenii, A. chiapensis, A. collinsii, A. cookii, A. cornigera, A. gentlei, A. globulifera, A. hindsii, A. mayana, A. melanoceras, and A. sphaerocephala) and one quasi-obligate ant-acacia (Acacia ruddiae) is based on extensive field study from 1963 to 1972 and on herbarium specimens where of use. The population boundaries of all species are mapped and described with respect to ecological parameters. Morphological variation, details of the interaction with the ants, and acacia reproductive biology are presented for most species.
A key to useful Australian acacias for the seasonally dry tropics provides a guide to widely planted Australian tropical Acacia species. The key includes a wealth of pictorial information and guides to related species and hybrids. It provides a concise key to the most likely Australian species to be encountered in the tropics and fills a gap in the resources currently available to field foresters in the tropics.
This guide describes, in pictures and words, all the different types of acacia trees that are such a distinctive feature of the Kenyan landscape. It shows both floral and vegetative characteristics - bark, leaves, pods, seeds - so that identification can easily be made even when the trees arenot in flower. This will be a valuable companion to anyone visiting or living in East Africa, and also to professional botanists, foresters, and ecologists. There are forty-four species of acacia in Kenya, out of twelve-hundred species globally, but they are of particular interest because they are both used by the local people and eaten by the wildlife. Acacias are also suited to commercial farming in arid conditions, which may be important if warmingtrends continue. The authors provide clear explanations of botanical terms, detailed field keys, and instructions for using the keys. No previous knowledge of plant sciences is required to enjoy this authoritative guide.
