In contradiction to some recently published accounts, an alternative perspective is offered on the struggle for power between Haiti & the Dominican Republic, particularly regarding the issue of the island of Hispaniola. It is argued that scholarship on this topic is flawed & one-sided, based on a distinctly anti-Haitian ideology, & perpetuates the assumption that these countries are "fated" to be enemies. The social & political function of this ideology is examined & the "fatal conflict" model that dominates these accounts is critiqued. Based on extensive ethnographic fieldwork, a reanalysis is offered of the history of Haitian-Dominican relations, revealing both past & present instances of cooperation & evidence that the interests & cultures of the two nations are converging. The real source of their continued disagreement concerns the issue of uncontrolled immigration on Hispaniola. 51 References. K. Hyatt Stewart

20 July 1500 Royal decree addressed to the King's retainer Pedro de Torres, ordering the release and repatriation of Indians brought to Spain from Hispaniola. The historian Altamira considered this document as the "first acknowledgement of the respect due to the dignity and freedom of all men, however ignorant and primitive they may be".

Die antillanische Flora ist eine der artenreichsten der Erde. Trotz jahrhundertelanger floristischer Forschung zeigen jüngere Studien, daß der Archipel noch immer weiße Flecken beherbergt. Das trifft besonders auf die Familie der Orchideen zu, deren letzte Bearbeitung für Cuba mehr als ein halbes Jahrhundert zurückliegt. Die vorliegende Arbeit basiert auf der lang ausstehenden Revision der Orchideengattung Pleurothallis R. Br. für die Flora de Cuba. Mittels weiterer morphologischer, palynologischer, molekulargenetischer, phytogeographischer und ökologischer Untersuchungen auch eines Florenteils der anderen Großen Antillen wird die Genese der großantillanischen Pleurothallis-Flora rekonstruiert. Der Archipel umfaßt mehr als 70 Arten dieser Gattung, wobei die Zahlen auf den einzelnen Inseln sehr verschieden sind: Cuba besitzt 39, Jamaica 23, Hispaniola 40 und Puerto Rico 11 Spezies. Das Zentrum der Diversität liegt im montanen Dreieck Ost-Cuba - Jamaica - Hispaniola, einer Region, die 95 % der groß-antillanischen Arten beherbergt, wovon 75% endemisch auf einer der Inseln sind. Da die meisten Arten entweder endemisch oder pankaribisch verbreitet sind, bleiben die floristischen Bezüge zwischen den Inseln und zu den kontinentalen Nachbargebieten nur schwach ausgeprägt. Immerhin lassen sich einige Verbindungen unter den Inseln der Großen Antillen und besonders zu Mittelamerika erkennen. Diese Affinitäten steigen von Ost nach West. Molekulargenetische und (mikro-)morphologische Daten zeigen ein deutliches Muster der historischen Biogeographie. Danach lassen sich die antillanischen Arten hinsichtlich ihrer Genese in drei Gruppen einteilen. 25% der Arten sind pankaribisch verbreitet, wobei der Großteil der Inselpopulationen vom mittelamerikanischen Festland stammt. Ebenfalls aus dieser Region stammen weitere 25%, die jedoch auf den Inseln neue Arten gebildet haben. Die verbleibenden 50% der groß-antillanischen Sippen sind autochthon und das Ergebnis adaptiver Radiation auf den Inseln. Diese intensive Kladogenese beschränkt sich auf drei Verwandtschaftskreise innerhalb der Gattung Pleurothallis in den Untergattungen Antilla Luer und Specklinia Lindl. (2 Linien). Es stellte sich heraus, daß der überwiegende Anteil der Artbildungsprozesse allopatrischer Natur ist. Sympatrie konnte nur in einem einzigen Fall direkt belegt werden. Das Ergebnis der allopatrischen Speziation sind zwei Typen von Vikarianz, räumlich geographischer und geologischer. In Cuba sind überraschenderweise fast 80% der endemischen Arten an einen Gesteinstyp gebunden, überwiegend an Serpentin. West-Hispaniola, wo viele Schwesternarten cubanischer Sippen beheimatet sind, besteht fast ausschließlich aus Kalkstein. Geographische Vikarianz ist daher oft geologisch unterlegt, eine Bindung die für Epiphyten kaum vermutet wurde. Hinter der Geologie verbergen sich jedoch eher Bestäuberareale und weniger physiologische Anpassung als limitierender Faktor. Eine Verfrachtung in Vegetation auf anderem petrologischen Untergrund scheint damit der Hauptauslöser für Artbildungen gewesen zu sein. Ausgangspunkt waren höchstwahrscheinlich individuenarme Gründerpopulationen die den Bedingungen eines founder events ausgesetzt waren. Neben den reichen geologischen Verhältnissen im Dreieck Ost-Cuba - Jamaica - Hispaniola wird die intensive Artbildung durch weitere spezifisch lokale Bedingungen unterstützt. Karibische Wirbelstürme dürften entlang der Hauptrouten für eine häufige Verfrachtung von Samen oder Pflanzen von Mittelamerika auf die Großen Antillen sowie zwischen den Inseln selber verantwortlich sein. Ein zweiter günstiger Umstand für erfolgreiche Migration innerhalb des Dreiecks besteht in der räumlichen Nähe der Inselgebirge und deren optimalen klimatischen Bedingungen für die Besiedlung durch mikrophytische Epiphyten. Molekulargenetische Daten lieferten weiterhin wertvolle Informationen in Bezug auf die beiden aktuell diskutierten Systeme der Pleurothallidinae, einer streng morphologischen (Luer) und einer fast ausschließlich auf DNA-Sequenzen (Pridgeon & Chase) basierenden Klassifikation. DNA-Sequenzen der cubanischen Arten stützen das neue System von Pridgeon & Chase weitestgehend, zeigen aber Widersprüche bezüglich der Monophylie in einigen der neuen oder wieder errichteten Taxa. Angesicht dessen, daß die karibische Florenregion leider nicht nur durch ihre Biodiversität zu den zehn globalen hot spots zählt, sondern auch durch die großflächige Zerstörung von Primärvegetation, war es auch ein Anliegen der vorliegenden Arbeit, ein erstes detailliertes Bild von Genese und Verbreitung antillanischer Orchideen zu vermitteln. Diese Daten können direkt für die Gestaltung und das Management von karibischen Schutzgebieten eingesetzt werden, da Orchideen in der Naturschutzpolitik einen hohen Argumentationswert besitzen. ; The Antillean Flora is one of the most diverse on our globe. However, despite floristic work for centuries recent studies show that there are still blank areas. This is especially the case in the family Orchidaceae, which, in the case of the Cuban Flora, has been reviewed more than half a century ago for the last time. The work presented here is based on the long pending revision of the genus Pleurothallis R. Br. for the Flora de Cuba. Adding further morphological, palynological, molecular, and ecological data this study is aimed at the reconstruction of the Greater Antillean Pleurothallis flora. The archipelago comprises more than 70 species of this genus, with a differing diversity on the particular islands; Cuba accommodates 39 taxa, Jamaica 23, Hispaniola 40 and Puerto Rico 11. The centre of diversity lies within the triangle E Cuba - Jamaica - W Hispaniola, a region that accommodates about 95% of the Greater Antillean species. 75% of the taxa are confined to just one island. Since most of the plants are either endemic or are of pan-Caribbean distribution floristic relationships among the islands and with regard to neighbouring continental areas remain rather indistinct. The strongest affinities are with Central America. Floristic relationships with that area increase from E towards W. Molecular and (micro-)morphological data show a clear pattern of historical phytogeography. Concerning their origin there are 3 groups of species. 25% of the Greater Antillean taxa are widespread in the Pan-Caribbean area, with the majority of the island populations having their origin presumably on the Central American continent. Another 25% are derived from Central American ancestors too, however, they have evolved into new species on the islands in the course of migration. The remaining 50% of the Greater Antillean taxa are autochthonous. They are the result of adaptive radiation on the archipelago. Intense cladogenesis is confined to 3 lineages within Pleurothallis. They belong to the subgenera Antilla Luer and Specklinia Lindl. (2 lineages). The majority of speciation events shows an allopatric pattern. Sympatry during speciation could be detected in a single case only. Allopatric speciation has resulted into 2 types of vicariance, spatial geographic and geological. Indeed, 80% of the Cuban endemics are associated with a single type of rock, serpentine in most cases. In contrast, W Hispanola where many sister taxa of Cuban pleurothallids live, is formed almost exclusively by limestone. In many cases, geographic vicariance is therefore geologically defined, a surprising association in epiphytic orchids. Geological vicariance, in turn, may have been brought about by pollinator distribution rather than by physiological adaptation to the geological environment. Migration to petrologically different localities seems to be the main trigger for speciation in Cuban Pleurothallis. This process was most probably started with a small number of individuals that met conditions of a founder event. Apart from the geologically rich background in the triangle E Cuba - Jamaica - Hispaniola there are other specific local conditions that are responsible for the rich diversity. Caribbean hurricanes provide a powerful means of transport along their main routes. They should be responsible for frequent migrations from the Central American mainland to the archipelago and between the islands. Moreover, the mountains within the triangle are in close spatial neighbourhood and meet favourable climatic conditions for the colonisation of small epiphytes. Molecular data from the Cuban species of Pleurothallis yielded valuable information for the current discussion concerning the morphological (Luer) and molecular classifications (Pridgeon & Chase) of the subtribe. These data support the new molecular based system to a great extent, however, they show new inconsistencies with respect to monophyly in some of the new or resurrected taxa. Considering that the Caribbean Flora belongs to the ten global hot spots, due to its diversity on the one and the loss of primal vegetation on the other side, it was a goal of the present thesis to impart a detailed picture of the genesis and distribution of Antillean orchids. Bearing in mind the political value of orchids in conservation these data can be used directly for the organisation and management of Caribbean nature reserves.

Boulder CO: Westview 1991. xxi + 387 pp. (Paper US$ 32.95)Few other places in the Caribbean region have as great a potential for international conflict as the island of Hispaniola. The historical antagonism between Haiti and the Dominican Republic is no doubt known to readers of this journal, as is the recent upsurge in tension between the two countries, which culminated in the expulsion of tens of thousands of Haitian immigrants from the Dominican Republic, from June to September 1991. The quickening pace of events, added to the worsening spiral of economic hardship gripping both nations, threaten to render obsolete even the most recent analyses of relations between the two countries. Even so, against the background of an increasingly acrimonious debate between the Dominican government and international human rights organizations accusing it of enslaving Haitian immigrants in the cane flelds, the appearance of two works by long-time students of the migration of Haitians as cane workers to the Dominican Republic is particularly timely.

The idea that sugar, plantations, slavery, and capitalism were all present at the birth of the Atlantic world has long dominated scholarly thinking. In nine original essays by a multinational group of top scholars, Tropical Babylons re-evaluates this so-called "sugar revolution." The most comprehensive comparative study to date of early Atlantic sugar economies, this collection presents a revisionist examination of the origins of society and economy in the Atlantic world.Focusing on areas colonized by Spain and Portugal (before the emergence of the Caribbean sugar colonies of England, France, and Holland), these essays show that despite reliance on common knowledge and technology, there were considerable variations in the way sugar was produced. With studies of Iberia, Madeira and the Canary Islands, Hispaniola, Cuba, Brazil, and Barbados, this volume demonstrates the similarities and differences between the plantation colonies, questions the very idea of a sugar revolution, and shows how the specific conditions in each colony influenced the way sugar was produced and the impact of that crop on the formation of "tropical Babylons"--multiracial societies of great oppression.Contributors:Alejandro de la Fuente, University of PittsburghHerbert Klein, Columbia UniversityJohn J.

Ithaca: Cornell University Press, 1992. xv + 280 pp. (Cloth US$ 39.95, Paper US$ 13.95)Ever since the first truly free nation of the Americas emerged from the agony of the Haitian Revolution, the western part of Hispaniola has been subject to torturous exertions of the European and American imagination. If, by reappropriating their own persons, the Haitians withheld a prime object of capitalist desire, their defiance was answered, in part, by the symbolic objectification of Haiti - this time not by merchants and empire-builders, but by philosophes, literati, and artists "organic" to various European and American regimes, anciens as well as nouveaux. Part of this was pragmatically motivated. The mere existence of Haiti spelled an immediate threat to the stability of New World polities predicated on the exploitation of unfree black labor. If slave revolts were endemic to the region, the events after 1791 seemed to exemplify the pandemic potential of black insurrection in its most virulent forms. Moreover, though direct connections to the events in St. Domingue could rarely be substantiated, the outbreaks of violence in Grenada, Demerara, Louisiana, St. Vincent, and Jamaica in the mid-1790s, and the subsequent proliferation (of real as well as imagined) plots in Cuba, Virginia, and Trinidad lent additional weight to fears aboutthe contagious nature of libertarian ideas (cf. Genovese 1979 and Geggus 1989 for rather different assessments of the reality behind such perceptions). Hence the frantic attempts to establish a cordon sanitaire between the source of revolutionary disease and those slave populations still uncontaminated - a course of action which may well represent one of the first instances of genuinely international information control. Yet slaveholders' recensions of the Haitian Revolution as symptomatic of a morbid process in need of containment did not exhaust its semantic potential.
