Seeds, bulbs, and cuttings of exotic plant species, including plants cultivated exclusively as ornamentals, were being advertised for sale in printed circulars in the United States by 1800. By the end of the 19th century seed trade catalogs were prolific and often listed dozens of exotic species that were already naturalized in the U.S. or new introductions from foreign suppliers. Among the species routinely offered for sale were many now considered noxious (e.g.,Berberis vulgaris, Eichhornia… 

A threat to biodiversity through international trading of grains and horticultural plant materials

International trade is a major route by which non-indigenous organisms are introduced into new habitats. Invasive species has been introduced as weed unintentionally through mass-trading of

Bagged Commercial Soils are an Avenue for Regional Dispersal of Weedy Plant Species

It is suggested the movement of different genotypes, even of common weeds, may create new evolutionary potential that could have long-term consequences for local adaptation of these species.

A century of the ornamental plant trade and its impact on invasion success

It is suggested that national economic factors are an important part of the explanation for the invasiveness of ornamental plant species, and hence for the development of potential solutions.


Herbarium records were studied to infer the introduction history and spread of the exotic Eurasian sickleweed (Falcaria vulgaris Bernh.) in the United States. The spread of the plant was

Conundrums of a complex vector for invasive species control: a detailed examination of the horticultural industry

Examination of the horticultural trade as a vector for invasive species, its agents, and the complexity of the distribution channel finds involvement and education of consumers may provide better oversight outcomes by addressing the moral hazard problem while acknowledging the key characteristics of the industry.

Exotic Acacia Species in Zimbabwe: A Historical and Ecological Perspective

The majority (88.9%) of exotic Acaciaspecies were introduced in the eastern part of Zimbabwe, a region characterized by tropical to semi-temperate climate, which is similar to the areas of origin of Acaciapecies.

The fate of alien conifers in long‐term plantings in the USA

Investigation of the specific fates of nine non-native conifers introduced into habitats in the USA through tree-ring analyses, comparisons of growth with adjacent native conifer populations, and surveys for regeneration and spread found no difference in the effect of climate on the annual growth of native and non- native conifer populations.

Should we care about purple loosestrife? The history of an invasive plant in North America

If purple loosestrife is not a primary cause of extinction or a major contributor to the decline of other species, but is instead an indicator of anthropogenic disturbances, the resources and efforts devoted to removing this species might be better focused on more effective means to protect wetlands against disturbances.

Effects of Defoliation on Growth and Reproduction of Brazilian Peppertree (Schinus Terebinthifolius)

It is inferred that multiple defoliations by insect defoliators have the potential to significantly suppress the growth and fruit production of Brazilian peppertree in Florida.



Native or introduced? Problems in the taxonomy and plant geography of some widely introduced annual brome-grasses

It is suggested that some species are not native in any primary habitats, and perhaps never have been, and though SW Asia seems to be the centre from which the current adaptive radiation of Bromus L. annuals began, not all its brome-grass flora is native.

Brazilian pepper—Its impact on people, animals and the environment

Native to Brazil,Schinus terebinthifolius Raddi, of the family Anacardiaceae, has been commonly cultivated in Florida for over 50 years as a dooryard ornamental. Use of its sprays of showy red fruits

Manual of the Vascular Flora of the Carolinas

This illustrated manual describes and discusses the unusually rich and varied flora of the Carolinas, from the semi-tropical coast of South Carolina to the northern forests of the high North Carolina

Introduction and Spread of Johnsongrass in the United States

An extensive search of the literature and records was conducted to determine when and how johnsongrass (Sorghum halepense (L.) Pers.) was introduced into the United States. Previous authors surmised

Purposefully Introduced Plants that Have Become Noxious or Poisonous Weeds

Research is in progress to develop methods of intercepting foreign plants that might be toxic to livestock if introduced on western ranges and pastures, including identifying poisonous plants from seed invention, chemical analysis, and feeding suspected plants to laboratory and domestic animals.

Manual of the Vascular Plants of Texas

This manual of the Texas flora is a monumental work and the authors, D. S. Correll and M. C. Johnston, as well as their collaborators, deserve the compliments of syste matists on its publication. A

Aquatic and wetland plants of southeastern United States

The first comprehensive survey of the aquatic and wetland plants of the Southeast, the Godfrey and Wooten volumes will prove invaluable to botanists, ecologists, college students, government agencies involved in land-use management, and nonspecialists interested in the plant life and ecology of the region.

Biological Control and the Reproductive Mode of Weeds

It is argued from this result that the genetic structure of the target species has important implications with respect to the selection of species to be controlled using biological agents.
