Mites Injurious to Economic Plants is a practical book written primarily for entomologists, agriculturists, and persons interested in controlling plant-feeding mites; it should also be of interest to biologists concerned with plant pathology, ecology, and evolution. The first six chapters provide general information on the morphology, physiology and development of mites, on mite-induced injuries to plants, enemies of mites, chemical control of mites, and population ecology. Accounts of individual families and species injurious to plants comprise the remaining eight chapters of the book.
Even the city dweller has a lot of botany close by, as the authors of this book quite well point out. Primarily based on the city of Boston, but applicable in many northeastern cities, the book discusses and pictures some of the plants found in dumps, sidewalk cracks, roof gutters, and (even) gardens.
This book is the result of queries and answers submitted to the New York Times garden page Question and Answer Column, from 1970 through 1974.
This book is one of Saunders’ Golden Series in Environmental Studies, and is a quite high level (but general) work slanted toward the “non-scientists, is based upon a freshman and sophomore university course.”
During 1975 field studies involving the genus Carex were undertaken as a part of a study leading to the preparation of a taxonomic and distributional treatment of the genus for Pennsylvania. As a result, a new state record and 27 county records were discovered, the most interesting of which are reported herein. Voucher specimens are deposited in The Herbarium of The Pennsylvania State University (PAC).
Sponsored by The International Association For Plant Taxonomy, and The Society of Systematic Zoology. These two international associations are the prime sponsors of an International Register of Computer Projects In Systematics. For the purpose of the Register, systematics includes taxonomy, biosystematics, evolution, and biogeography of all biological taxa; the Register also welcomes information about nonbiological data files of use to systematics (e.g., the long range weather data tapes of the U.S. Weather Bureau). For the present, our project is a Register, which hopefully can direct people to the source of information desired. Depending on demand, it could be extended into a repository and clearing house for computerized files of systematic value.
During class field work on the Lake Erie islands in summer 1974 at Stone Laboratory of The Ohio State University, I collected three species of vascular plants not included in Weishaupt’s Vascular Plants of Ohio (1971); a fourth species not in that work was found in Cincinnati by Dr. Jerry H. Carpenter. These four species, apparently representing new records for Ohio, seem to be infrequent to rare in the range of Gray’s Manual of Botany. The voucher specimens are deposited in the herbarium of The Ohio State University (OS) and in the Gray Herbarium (GH).
Jones et al., (1969) presented a list of Pteridophytes, including four species of Lycopodium, found in Mississippi based on collections made during the Mississippi Flora Project. They also called attention to certain ferns and primitive vascular plants not found and indicated specifically that Lycopodium cernuum L. should be searched for, in view of distributional data given for the species by Wherry (1964), Lowe (1921), and Small (1938). A study of pitcher plant bogs in Mississippi by Eleuterius and Jones (1969) also failed to yield L. cernuum.
Ailanthus altissima, Lonicera japonica, Polygonum cuspidatum, Pueraria lobata and Rosa multiflora are eastern Asian plants, introduced into the United States as ornamentals during the past 200 years. Lonicera japonica and Pueraria lobata are already recognized as serious noxious weeds. Ailanthus altissima is a local nuisance, and Polygonum cuspidatum and Rosa multiflora are potential problems. Ailanthus altissima is established in 48 counties in North Carolina, Lonicera japonica in 97, Polygonum cuspidatum in 27, Pueraria lobata in 62, and Rosa multiflora in 57.
