Taxonomy And Systematics Of Plumeria L. (Apocynaceae) In The Caribbean Islands, Nichole M. Tiernan
FIU Electronic Theses and Dissertations
Plumeria L. (Apocynaceae) is a genus of flowering trees and shrubs that are often cultivated in tropical gardens worldwide. The majority of its species occur in the Greater Antilles with many as single-island endemics. The only comprehensive revision for the genus was done by Robert E. Woodson Jr. (1937) who recognized only seven species and created a ‘Plumeria obtusa complex’ with a plethora of synonyms. The first study provides an overview of the Caribbean Island members of the genus with a focus on Plumeria filifolia Griseb., a thin-leaved species endemic to Cuba that is featured because of its incredible …

Evolutionary Genetics Of The Genus Zamia (Zamiaceae, Cycadales), Michael Calonje
FIU Electronic Theses and Dissertations
The genus Zamia L. (Zamiaceae), consisting of 77 species, is the most species-rich and widely distributed cycad genus in the New World and is arguably the most morphologically and ecologically diverse genus in the Cycadales. We utilized a multilocus sequence dataset of 10 independent loci (9 single copy nuclear genes + 1 plastid) and extensive taxon sampling (over 90% of species) to infer phylogenetic relationships within Zamia. We infer a robust phylogenetic tree for the genus with a strong geographic delimitation of clades and find that four morphological characters typically used for diagnostic purposes in the genus exhibit a high …
