Woody and Herbaceous Plants Native to Haiti for Use in Miami-Dade Landscapes1
Woody and Herbaceous Plants Native to Haiti For use in Miami-Dade Landscapes1 Haiti occupies the western one third of the island of Hispaniola with the Dominican Republic the remainder. Of all the islands within the Caribbean basin Hispaniola possesses the most varied flora after that of Cuba. The plants contained in this review have been recorded as native to Haiti, though some may now have been extirpated due in large part to severe deforestation. Less than 1.5% of the country’s original tree-cover remains. Haiti’s future is critically tied to re- forestation; loss of tree cover has been so profound that exotic fast growing trees, rather than native species, are being used to halt soil erosion and lessen the risk of mudslides. For more information concerning Haiti’s ecological plight consult references at the end of this document. For present purposes all of the trees listed below are native to Haiti, which is why non-natives such as mango (the most widely planted tree) and other important trees such as citrus, kassod tree (Senna siamea) and lead tree (Leucanea leucocephala) are not included. The latter two trees are among the fast growing species used for re-forestation. The Smithsonian National Museum of Natural History’s Flora of the West Indies was an invaluable tool in assessing the range of plants native to Haiti. Not surprisingly many of the listed trees and shrubs 1 John McLaughlin Ph.D. U.F./Miami-Dade County Extension Office, Homestead, FL 33030 Page | 1 are found in other parts of the Caribbean with some also native to South Florida.

The Plant Taxa of H.N. Ridley, 5. the Gentianales
Gardens' Bulletin Singapore 70 (2): 307–395. 2018 307 doi: 10.26492/gbs70(2).2018-08 The plant taxa of H.N. Ridley, 5. The Gentianales I.M. Turner1, 2, Y.W. Low2, M. Rodda2, K.M. Wong2 & D.J. Middleton2 1Singapore Botanical Liaison Officer, Royal Botanic Gardens Kew, Richmond, Surrey TW9 3AE, U.K. [email protected] 2Singapore Botanic Gardens, National Parks Board, 1 Cluny Road, 259569, Singapore ABSTRACT. Henry Nicholas Ridley (1855–1956) described more than 450 taxa of Gentianales, mostly from Southeast Asia, and was the author of over 70 additional combinations in this order. A listing of these names with place of publication and the types of the Ridley basionyms is given here. Many names are lectotypified. The new combinations Chassalia pauciflora (Ridl.) I.M.Turner and Chassalia violascens (Ridl.) I.M.Turner are proposed for Cephaelis pauciflora Ridl. and Gartnera violascens Ridl. respecitively. Three names are newly reduced to synonymy: Cephaelis elongata Ridl. to Chassalia bracteata Ridl., Geophila matthewii Ridl. to Mussaenda uniflora Wall. ex G.Don and Psychotria setistipula Ridl. to Ixora patens Ridl. Keywords. Apocynaceae, Gentianaceae, lectotype, Loganiaceae, Rubiaceae, typification Introduction This paper continues an intermittent series on the plant taxa named by Henry Nicholas Ridley (1855–1956). Earlier parts have covered the pteridophytes (Turner & Chin, 1998a), gymnosperms (Turner & Chin, 1998b), Zingiberales (Turner, 2000) and basal angiosperms (Austrobaileyales, Canellales, Chloranthales, Laurales, Magnoliales, Nymphaeales and Piperales) (Turner, 2012). In this installment focus shifts to the Gentianales. Ridley described many plant species, particularly from Southeast Asia. He documented the botanical diversity of the region tirelessly and seemed prepared to tackle all and any taxonomic group of vascular plants that came his way.

F. L. von Schlechtendal and type material of his new taxa preserved in the herbarium of Martin Luther University Halle-Wittenberg (HAL) and other botanical collections. Schlechtendalia 31: 1–143. D. F. L. von Schlechtendal (1794–1866) was professor of botany and director of the botanical garden in Halle (Saale) from 1833 to 1866. He was one of the leading and most productive German botanists of the 19th century, who, inter alia, introduced about 1,600 new taxa, most of them new species, including 78 new genera. Schlechtendal‟s private herbarium was purchased by the university after his death from his widow and represents the historical nucleus of the present-day herbarium of the Martin Luther University (HAL). Based on Schubert‟s (1964) unpublished dissertation and other sources, Schlechtendal‟s life and work is outlined. All taxa described by Schlechtendal are summarized in an annotated list, including details of type collections preserved in the herbarium of Martin Luther University Halle- Wittenberg and in other botanical collections. Previous typifications of the taxa concerned were scrutinized in the light of the rules of the Internal Code of Nomenclature for Algae, Fungi, and Plants.

Guettarda Elliptica Sw. Velvetseed RUBIACEAE Synonyms
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by CiteSeerX Guettarda elliptica Sw. velvetseed RUBIACEAE Synonyms: Guettarda bladgettii Shuttlew. ex Chapm. Matthiola elliptica (Sw.) Kuntze (author’s observation). Range.—The native range of velvetseed extends from southern Florida through the West Indies, from Mexico through Central America, and Venezuela and Guyana in South America (Little and others 1974). Ecology.—Velvetseed grows in pinelands and hammocks in Florida (Nelson 1996). In Puerto Rico, it is most common in limestone areas and occasionally in areas of igneous rock, on rocky ridge sites too difficult for tall vegetation, and in coastal thickets and rocky hills (Liogier 1997, Little and others 1974). Annual rainfall varies from 750 mm to 2200 mm, and elevations range form near sea level to about 400 m. Vegetation sites include relatively pristine to highly disturbed remnant forests and late secondary forests. Velvetseed is moderately intolerant of shade. It competes well with slow-growing vegetation but not with tall grass or overtopping trees. Open- grown plants assume a symmetrical shape, but in General Description.—Velvetseed, also known as thickets, the stems are usually crooked and the Everglade velvetseed, pickle-wood, cucubano liso, crowns asymmetrical. cigüillo, cuero de sabana crucillo, guayabillo prieto, cabrito, guayabillo prieto, and punteral, is a Reproduction.—Velvetseed blooms in summer in shrub or small tree to 6 m in height and 10 cm in Florida (West and Arnold 1952) and in the spring stem diameter. It usually has multiple stems from in Puerto Rico (Little and others 1974). Flowers below or just above the ground level.
