Typification of four North American club-chollas: the names of four Engelmannian species from Mexico and Southwestern United States

The names Opuntia bulbispina, O. clavata, O. emoryi and O. grahamii, originally proposed by George Engelmann between 1848 and 1856, are reviewed and typified after new findings of previously unknown voucher specimens. Original materials collected by some of the collaborators employed by Engelmann during the Mexican Boundary Survey were discovered in a loan from the Torrey Herbarium at the New York Botanical Garden (NY). Many of the materials include fragments of stems and fruits, and others include only sectioned flowers and some seeds. Particularly good descriptions of the species here concerned were published in Engelmann’s “Synopsis of the Cactaceae” in 1857, and exceptional illustrations were produced by Paulus Roetter and printed in “Cactaceae of the Boundary” in 1859. The problems surrounding some previous typifications of these names range from typification of joint lectotypes to illegitimate typifications of illustrations when original material was known to exist. The materials selected for typification were collected by the Mexican Boundary Survey and are lodged at the herbaria of the Missouri Botanical Garden (MO) and the New York Botanical Garden (NY); some are illustrations published by Engelmann.

Barriers faced by the Brazilian business community to access the United States market system

Trade history between Brazil and the United States is long and complicated but it is only in recent years that the trade balance has become more equal in terms of both imports and exports. As Brazil continues to establish its position in the world economy and expand its export market it is only natural that it seeks to increase exports to its single largest trading partner, the United States, and maintain the market share already established. In order to achieve success in these regards Brazil must have a deep understanding of the American political economy system. Part of this entails understanding barriers that must be overcome by Brazilian businesses to access United States markets, particularly the access of certain products at the industry level.
