Seven plant genera are regarded as endemic to Jamaica [Dendrocousinsia (seven species, Euphorbiaceae), Jacmaia (one species, Asteraceae), Odontocline (six species, Asteraceae), Portlandia (six species, Rubiaceae), Salpixantha (two species, Acanthaceae), Tetrasiphon (one species, Celastraceae) and Zemisia (one species, Asteraceae)]. A review pertine...

Euphorbia tuckeyana is a dendroid spurge endemic to Cabo Verde. It belongs to E. subgenus Esula section Aphyllis subsection Macaronesicae, a monophyletic group of eleven species restricted to the Canaries, Madeira archipelago, the Selvagens islands, Cabo Verde, a small area of Atlantic Morocco, and Portugal, that have high horticultural potential f...
Article
Coccothrinax argentata (Arecaceae) occurs in southern Florida, both on the mainland and in the islands of the Florida Keys. However, the palms from the mainland and Keys display morphological differences that led taxonomists to recognize them as distinct species in the past. They are now treated as a single, polymorphic species, but the question re...

Recent systematic treatments for Jamaica have shown that the island is home to seven endemic genera of seed-plants [viz., Dendrocousinsia (Euphorbiaceae), Jacmaia (Asteraceae), Odontocline (Asteraceae), Portlandia (Rubiaceae), Salpixantha (Acanthaceae), Tetrasiphon (Celastraceae), and Zemisia (Asteraceae)]. These taxa account for over 23 species, w...

With 30 threatened species (14 categorized as Critically Endangered and 16 as Endangered, sensu IUCN), Coccothrinax (c. 54 species) is the flagship palm genus for conservation in the Caribbean Island Biodiversity Hotspot. Coccothrinax has its centre of taxonomic diversity in these islands, with c. 51 endemic species. We present a conservation frame...

Brother Marie-Victorin (1885–1944) was a member of the Roman Catholic congregation of the La Salle Brothers and one of the most important figures in the botanical history of Canada. In 1929, he undertook a 7-month trip across Europe, Africa and the Middle East. During this journey he visited the islands of Gran Canaria (26–27 June) and Tenerife (28...
Article
David Fairchild (1869-1954) was one of the most important plant explorers and collectors from the USA. His documents, letters, and photographs are housed at the Archives and Library of Fairchild Tropical Botanic Garden (ALFTBG). Between 1925 and 1933, Fairchild mostly performed his plant hunting activities on board the research yacht Utowana. The l...
Article
Palms (Arecaceae) are perhaps the most important tropical plant family for human use, both for utility and ornamental horticulture. The wide diversity of palm species with different seed germination characteristics necessitates tailoring horticultural practices to the needs of each. This is crucial for production and conservation horticulture. In t...

Coccothrinax jimenezii M.M. Mejía & R.G. García is a Critically Endangered palm species restricted to Haiti (one population near the city of Gonaïves with 43 individuals) and the Dominican Republic (one population on the shores of Lago Enriquillo with 18 individuals). The species faces two major conservation challenges: (1) water level rise in the...

Salvia subg. Calosphace sect. Gardoquiiflorae is re-examined, and three species, all endemic to Hispaniola (Greater Antilles), are recognized. The names S. brachyloba, S. buchii and S. selleana are here lectotypified. Detailed morphological descriptions, distribution maps, information about habitat, and an identification key to the species are prov...
Article
In March and April 1948, David Fairchild undertook a plant hunting expedition to Venezuela and Colombia. His wife, Marian, accompanied him on this, his last official plant exploration endeavor. A total of 62 plant samples (41 from Venezuela and 21 from Colombia) were collected. In addition, 55 photographs (41 from Venezuela and 14 from Colombia) we...

Article
Pseudophoenix ekmanii, P. lediniana and P. vinifera (Arecaceae) are endemic to Hispaniola. The more wide-ranging P. sargentii also occurs on the island. Population genetic diversity and structure of Pseudophoenix was investigated using ten microsatellite loci. The study focused on populations from Hispaniola, but also included samples from other Ca...

The palm species Pseudophoenix ekmanii (endemic to the Dominican Republic) and P. lediniana (endemic to Haiti) are the only Critically Endangered species (sensu IUCN) of the genus. Results are presented of recent field research and population genetic studies targeting P. lediniana. The field research confirmed that wild plants of P. lediniana are r...
Article
Arecaceae tribe Cocoseae is the most economically important tribe of palms, including both coconut and African oil palm. It is mostly represented in the Neotropics, with one and two genera endemic to South Africa and Madagascar, respectively. Using primers for six single copy WRKY gene family loci, we amplified DNA from 96 samples representing all...

Aim: Rubiaceae is one of the largest families of plants and it includes the Jamaican genus Portlandia. This family has been used in several ethnomedicinal practices. Thus, in this study we investigated whether extracts of two species of Portlandia affect In vitro proliferation of breast cancer cells. Study Design: Metastatic (MDA-MB-231 and HeLa) c...

This is an introductory paper for a Special Issue of Botanical Review devoted to plant biodiversity in the Bahamian archipelago. The papers published in this issue represent some of the contributions presented at a symposium that took place in Nassau in October 30 and 31, 2012 to celebrate the 30 year anniversary of the publication of the “Flora of...
Article
Dr. John Popenoe was Director of Fairchild Tropical Botanic Garden (FTBG) between 1963 and 1989. Dr. Popenoe was a strong supporter of the Bahamian flora, and in 1963 he obtained extramural funds to develop a living collection focusing on Bahamian plants that was established in FTBG. During his tenure FTBG supported the publication of the latest co...

The plant hunting expeditions made by David Fairchild on board the research boat Utowana represented some of the most important contributions in the history of plant exploration. These expeditions targeted all the continents except Australia and Antarctica and provided germplasm for the United States Department of Agriculture. As part of our curren...

The Bahamian archipelago has a rich flora with 89 endemic species. An international symposium held at Nassau in October 2012 to celebrate the 30th anniversary of the publication of the "Flora of the Bahama Archipelago" provided a forum to discuss plant conservation issues on these islands. This article builds on conclusions from this symposium and...
Article
The Bahamian archipelago consists of approximately 2,400 islands occur- ring in the Atlantic Ocean off the coasts of Florida, Cuba, and Hispaniola. In 1982 Donovan Correll and Helen Correll published the most current synopsis of the floristic diversity of this island chain. Their publication cited a total of 1,371 vascular plant species of which 11...
Article
The nomenclature of Dendrocousinsia (Hippomaneae, Euphorbiaceae) is revised and we present four new taxonomic combinations within the genus. It comprises six species and one variety. Extensive field surveys were conducted and conservation assessments are presented based on the IUCN redlist system for threatened species. Three of the species are Cri...

Since the first collection in 1910, botanists have recognized Sarcopilea (Urticaceae) as a dramatic example of convergence with succulent woody members of Crassulaceae. Phylogenetic analyses based on nuclear ribosomal DNA ITS and the trnL-F non-coding plastid DNA regions place Sarcopilea in a Neotropical clade of Pilea. A study of the cystolith, po...

We examined the phylogeny and intergeneric relationships among the 12 genera of the palm subtribe Ptychospermatinae. While many of these taxa are familiar, cultivated ornamental palms in warm areas of the world, the monophyly of the subtribe and its component genera required testing. We also examined the biogeographic relationships of this lineage,...

The Caribbean islands, despite centuries of large-scale habitat loss, still contain habitats of amazing beauty and, importantly, these habitats provide an integral foundation for the islands’ sustainable development. These surviving habitats contain unique plant diversity found nowhere else on the planet and for some families, most notably the Aste...
