Book Description
"Contains chapters on the conservation of herbarium sheets and on the collection and curation of the larger algae. The chapter on computers has been completely rewritten and much enlarged, as have those on pests and treatments, larger fungi and economic botany. The sections on liquid preservatives and on pesticides have been revised to take into account new health and safety regulations. An essential reference work for herbarium managers and technicians and for all those who are involved with the making and maintenance of herbarium collections." --NHBS Environment Bookstore.

Book Description
This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1899 edition. Excerpt: ... CHAPTER IV DIRECTIONS FOR PARTICULAR FAMILIES Methods with Cactaceae. -- At first sight nothing can appear more obdurate than certain cactacess. Many of them are beset with sharp, bayonet-like spines, their points directed simultaneously in several directions. No one touches them with impunity. In hedges they are the despair of poacher, scout, or soldier. They form an impenetrable trocha. The common prickly pear ( Opuntia), which has not these long, projecting spines, is armed with even more dangerous weapons. Where leaves should be are groups of needle-like prickles, dislodged at a touch, and filling the skin with their painful barbs. Again, the Cactacece are coarse, succulent, and, in bulk, unmanageable. One could hardly press a complete specimen, however small. Fortunately this is not required. In case of the Platopuntice the joints can be split and the soft interior removed. Again, the flowers may be sectioned, and the portions dried. When the species are cylindric the branches are split and most of the fleshy interior removed. It is then easily possible to flatten the resulting halves. The object in each case is to exhibit the prickly or spiny areolae. Treated thus, the specimens present no difficulties in drying. Longitudinal sections of Echinocactus are essential. It is important to display the relative distances of the areolae, and at the same time the sharpness or bluntness of the ribs. These sections should reach to the utmost extremities in order to show the very important designative character of the tomentum of the areolae. Count and record on the field-label the number of ribs. Mammilaria is treated somewhat differently. Large quarter sections are cut from the apex downwards. Remove as much as possible of the soft parts and...

Book Description
Tropical Plant Collecting provides field biologists with information about carrying out fieldwork in tropical America, gathering botanical collections, managing specimens in herbaria, making information about plants available on the Internet, and raising money to fund both expeditions and the preparation of floras and monographs. The book is based on over 40 years of tropical plant collecting in Central and South America by the senior editor and his colleagues. Although traditional field and herbarium techniques are discussed, the book emphasizes how new techniques provided by digital photography, databases, and the Internet have revolutionized plant collecting and data presentation in systematic botany. The audience for this book is tropical biologists and students who, as part of their research, need to gather botanical specimens to document their scientific studies.

Book Description
"What good is a dead plant? A lot! Herbaria, a picture book for grades one through eight, explains why, leading readers on an accessible, engaging exploration of who loves dead plants--and why. In these pages, we learn about famous historical plant collectors and the paths they established investigating plants. Readers join today's field botanists as they go far and wide to discover new species, and we get to look in the herbarium at how specimens are mounted and organized for everyone to use and enjoy. The book as a whole helps kids to visualize themselves as botanists gathering, preserving, and unlocking the mysteries of plants. In addition to beautiful watercolor illustrations and photos, the book includes interactive features such as lift-a-flaps, overlays, and a foldout." --Publisher's description.
