Die Akasias, algemeen bekend as "doringbome", is waarskynlik the
kenmerkendste en mees bekende groep bome in Afrika. Hulle is een
van die grootste groepe en word gewoonlik met 'n tipiese Afrika
landskap geassosieer. Hierdie omvattende boek, veldgids tot die
Akasias van Suid-Afrika, maak dit maklik om Akasias te identifiseer
en sluit in: 'n Volledige weergawe van al 48 erkende spesies,
subspesies en varieteite van die genus Acacia wat binne die grense
van Suid-Afrika voorkom, insluitende vier nuut beskryfde spesies.
Kleur illustrasies van die mees belangrike aspekte rakende die
identifikasie van hierdie plante. Bondige teks waarin die habitat,
algemene voorkoms, hoofstam, lote, dorings, blare, bloeiwyse, peule
en saad van elke vorm beskryf word. 'n Verspreidingskaart van elke
vorm.
Plants provide the food, shelter, medicines, and biomass that
underlie sustainable life. One of the earliest and often overlooked
uses of plants is the production of smoke, dating to the time of
early hominid species. Plant-derived smoke has had an enormous
socio-economic impact throughout human history, being burned for
medicinal and recreational purposes, magico-religious ceremonies,
pest control, food preservation, and flavoring, perfumes, and
incense. In ten illustrated chapters, this global compendium
documents and describes approximately 2,000 global uses for over
1,400 plant species. The Uses and Abuses of Plant-Derived Smoke is
accessibly written and provides a wealth of information not only on
human uses, but also on conservation issues and the role of smoke,
fire, and heat in promoting seed germination in biodiversity hot
spots. Divided into nine main categories of use, the compendium
lists plant-derived smoke's the medicinal, historical, ceremonial,
ritual and recreational uses. Plant use in the production of
incense and to preserve and flavor foods and beverages is also
included. Each entry includes full binomial names and family, an
identification of the person who named the plant, as well as
numerous references to and other scholarly texts. Of particular
interest will be plants such as Tobacco (Nicotiana tabaccum),
Boswellia spp (frankincense), and Datura stramonium (smoked as a
treatment for asthma all over the world), all of which are
described in great detail. In addition, this is one of the first
ethnobotanical books to include a section on plant conservation. It
addresses issues of over-harvest and invasiveness, the two primary
conservation concerns with human-exploited species.
This book offers 10 'recipes' for Woodland adventures, each
structured around a story which is designed to capture the
imagination of 2-6 year olds. Each recipe provides parents and
carers with a list of the kit required (generally, simple household
objects) and a set of step by step instructions. A strong addition
to the successful Frances Lincoln creative parenting list, this
book focuses on activities for younger children, and connects with
the fast-growing Forest School movement.
Back in print just in time for spring! Originally published in
1948, this is the germinal text on nearly 250 species of spring
wildflowers found in West Virginia. Common or English names and
scientific or Latin names are given for each species. The
descriptions are in two sections: The first description includes
the meaning of the name of the flower, uses, habitats, and ranges
in West Virginia. Secondly, the plant itself is described in deep
detail to help in identification. Each description is accompanied
by a facing page detailed line drawing. This book is a must have
for those interested in the beauty and science of West Virginia's
spring flora.
Botanists and seed collectors Rod and Rachel Saunders set out on what seemed to some to be an impossible mission – to find and photograph, in full bloom, all gladioli species found in South Africa and to collect and share their observations in a field guide. They had found all but one species before their untimely deaths at the hands of kidnappers in a forest in KwaZulu-Natal.
In the wake of this tragic event, friends and colleagues collaborated to keep the Saunders’ dream alive. This book is the result their collective efforts.
Gladioli are showy bulbous plants that fall within the Iris family, and the bulk of species are endemic to South Africa. Comprehensive and lavishly illustrated with more than 1,300 photographs, this guide covers the 166 Gladiolus species known to occur in the region.
The book is divided into seven taxonomic sections, according to the species’ distinguishing features. Each species is presented on a double-page spread, with a full plate of color photographs, including close-ups of diagnostic features, different color forms and habitats. Botanical descriptions cover identification (corm, cataphyll, spike, bracts, anthers, pollen, capsules, seeds, and scent), distribution, pollination, conservation status, and notes on ecology and the authors’ personal observations in the field. Distribution maps and flowering periods are given for each species, and tables highlight differences between similar-looking gladioli.
There are almost 300 recognized species, widely distributed across Africa, Europe and the Middle East, with more than half of the species found in southern Africa, making this book useful to botanists world-wide, as well as to horticulturist, propagators, students, gardeners and anyone with an interest in natural history.
