A critically endangered species from South Florida}, year = {2007}, keywords = {}, doi = {}, url = {}, pmid = {}, journal = {Botanical Journal of the Linnean Society}, volume = {}, number = {}, pages = {}, abstract = {Jacquemontia reclinata House (Convolvulaceae) is a federally listed endangered species endemic to coastal strand habitat of southeastern Florida. In order to identify the closest relatives of J. reclinata, a phylogenetic reconstruction was performed based on nucleotide sequence data from the internal transcribed spacer region of nuclear ribosomal DNA and from the trnH-psbA intergenic spacer of chloroplast DNA. We included the three putative relatives of J. reclinata and the majority of Jacquemontia Choicy species known to occur in the Caribbean Islands. The strict consensus tree concurs with previous morphological studies, indicating that J. reclinata is closely related to the Caribbean species J. cayensis Britton, J. curtisii Hallier f., and J. havanensis (Jacq.) Urb. These three species and J. reclinata form an unresolved clade. Nucleotide divergence within this clade is low, suggesting that the group is recent, perhaps diversifying after the latest glacial period. These taxa need to be study further using population level DNA markers. Most species endemic to the Caribbean Basin form a strongly supported clade. Our phylogeny supports Convolvulus nodiflorus Desr. as part of Jacquemontia. In addition, J. ovalifolia (West) Hallier f. subsp. sandwicensis (A. Gray) K.R. Robertson is sister to the Antillean endemic J. solanifolia (L.) Hallier f.} }
