-3- taxonomists when attaching a problem in systematics. Since the plants are quite large, it is difficult to make a very complete herbarium specimen by ordinary techniques. Usually, a collector makes no specimen unless it bear flower or fruit. These plants when in flower or fruit have different leaf (and other such characters) from those of the vegetative conditions. Since flowering and fruiting are of sporadic occurrence in this group, it is necessary to rely mainly on vegetative characteristics. Due to this fact, plus others, I have little valid material with which to start this work. In order to quickly bring …

special recognition for having accumulated, in the brief period of its existence, 40,000 mounted specimens. A word about the library. It was started through the presentation, by Dr. A.J. Sharp, of Knoxville, Tenn., of his personal library. Additional material was contributed by Dr. Ian Baker, of the British Embassy in Mexico. The collection now numbers approximately 3700 volumes, while the hemeroteca (the collection of periodical literature) now contains 225 publications titles. There is a special section of reference works in the library covering the entire field of biology and related subjects, with a very larg …

Duke University DUNHAM NORTH CAROLINA DEPARTMENT OF BOTANY February 3, 1933 John M. Fogg, Jr., Curator of Herbarium Botanical Laboratory University of Pennsylvania Philadelphia, Penn. Dear Mr. Fogg: I am delighted over having your enquiry concerning the exchange of plant specimens. Yes, I am very much interested at present in the flora of this state, but have not gotten much beyond grasses, Pteridophytes, Bryophytes, and Cyperaceae. I am especially interested in your New Jersey pine barren flora. We have been and will be for some weeks yet quite busy trying to straighten out our herbarium, so we are not quite rea …

- 8 - In the first place, consider what botanical gardens are: by their very nature they are treasuries of botanical diversity, growing everything from algae to redwoods and displaying a wide array of native and exotic species and cultivars, outside and under glass. It is not uncommon for a garden to maintain several thousand kinds of plants in a score of natural or simulated habitats. Regardless of the quality and extent of documentation, the mere fact that such an aggregation of genotypes is consistently maintained has pertinent conservation value, and augurs well for a more direct role in botanical conservatio …

- 17 - to maintain the genetic base and destruction due to public use was very great. Dr. Rogers cited the lack of cooperation between institutions as being a problem. Those with the longest history, the botanic gardens, lost their role of distributing plants such as the rubber tree and the oil palm, when agriculture became more scientific. They are now more concerned with the maintenance of floral and decorative plants. They have good seed exchange programs and systematic collections. It was pointed out that many institutions have a "reserve" of land where an effort is made to leave things as they are. Numerous …

There are other sources of plant material that frequently is not recognized as genetic resource conservation, but still provides a broad range of plant materials that would otherwise not be generally available. These are the commercial seed companies. Throughout the US, these companies provide many vegetables, fruits, flowering plants and curiosities raised for some particular interest, such as the sensitive plant (Mimosa pudica) the telegraph plant (Desmodium gyrans), the Venus fl …

for bibliographical studies of botanical and horticultural literature than it is a library in the conventional sense. Its collections, which serve as the tools for its research program, are divided into four categories: Books. These number about 11,000 titles of bound volumes and 2,500 of pamphlets (largely of botanical biography). The strength of the book collection is in works of the midnineteenth century and earlier, and particularly of those on systematic botany, medical and economic botany, herbals, early agriculture, gardening, and voyages. It has a strong representation in both early and contemporary works …

expeditions to various parts of the New and Old World were mounted. Almost every voyage had botanists along with the mission of discovering new and useful plants for the country sponsoring the expedition. These botanists expanded the knowledge of plants by bringing back living and dried specimens for the botanical gardens. At the gardens, new types of endeavors were fostered--the science of classification was given stimulus and support; interest in better methods of growing the plants and caring for them gave impetus for the science of horticulture. The basic functional aspects of plant growth began with fertiliz …

… ns with programs in the tropics, where both speciation generally and problems associated with the protection of rare and endangered species are greater (in part because so little is known about them), such institutions might well become engaged in the preservation of certain tropical groups. International coordination is obviously essential to success in such a complex endeavor, and several conferences addressing this topic have been held in recent years. To summarize, botanical gardens, the only human institution created to display and interpret plants for people, are central to all activities associated with th …

The gathering of plants to be used in schools as specimens for class instruction can be obviated by school authorities arranging to purchase such supplies from botanic gardens or nurseries where they have been BIRD-FOOT VIOLET (Viola pedata). raised in large numbers for the purpose. Such an arrangement has been made between a few teachers of botany in Boston, and the PLYMOUTH MAYFLOWER, TRAILING ARBUTUS (Epigaea repens). directors of the Bussey Institute of Harvard University. Well might a portion of city parks and public gardens be devoted to the raising of such plants as are in dema …
