In this study, the genera are listed and their distribution patterns among the floristic provinces of Mexico origins in 1 analyzed.

Onagraceae) in North America, Based on Parsimony Analysis of Endemicity and Track Compatibility Analysis1
GEOGRAPHICAL Liliana Katinas,2 Jorge V. Crisci,2 Warren 3 4 DIVERSIFICATION OF L. Wagner, and Peter C. Hoch TRIBES EPILOBIEAE, GONGYLOCARPEAE, AND ONAGREAE (ONAGRACEAE) IN NORTH AMERICA, BASED ON PARSIMONY ANALYSIS OF ENDEMICITY AND TRACK COMPATIBILITY ANALYSIS1 ABSTRACT Tribes Epilobieae, Gongylocarpeae, and Onagreae, a monophyletic branch in the family Onagraceae, comprise genera endemic to or having their major basal radiation in the Madrean Floristic Region of southwestern North America. Parsimony analysis of endemicity (PAE) and panbiogeography (track compatibility analysis) were performed in order to seek an historical explanation for the patterns of high diversity and endemicity for the group in this region. Twenty- one areas of endemism are delimited, based on previous biogeographic schemes and presence of endemic plant and animal taxa. Based on distributional data on 173 species, a strict consensus PAE cladogram shows four main groups of areas: northern North America, the central Mexican areas, western North America, and eastern North America. Track compatibility analysis resulted in two strongly supported generalized tracks: one includes eastern North America, and the other western North America. PAE and panbiogeographical analyses of the distributional patterns of these taxa suggest a close relationship of eastern and western North America, with both areas more related to the Neotropics than to the Palearctic, and a rather weak association between northern North America and Asia. The discovery of two tracks in eastern and western North America for Epilobieae, Gongylocarpeae, and Onagreae reveal little relationship of North America with Asia or other continents. These tribes display a distinct but contemporaneous biogeographical history that differs from those of the Holarctic. -

PhytoKeys 7: 37–40. doi: 10.3897/phytokeys.7.2088 Abstract Fleischmannia profusa is named as new from El Salvador based on material with deltoid leaf blades, numer- ous axillary fascicles of leaves on the vegetative stems and c. 60 sharply obviously acuminate involucral bracts in 4-5 strongly gradate series. Keywords Fleischmannia, Eupatorieae, Asteraceae, Mesoamerica, El Salvador Introduction Since the redefinition of the limits of the genus Fleischmannia Sch.Bip. (King and Robinson 1966, 1970) numerous studies have added species to the genus for the Flora Mesoamerica area (King and Robinson 1972, 1974, 1975, 1978, 1991; Robinson 2001). A further revision of the manuscript for the Eupatorieae of Mesoamerica has revealed an additional distinctive species of Fleischmannia in need of description. The species is named “profusa” because of the numerous small axillary fascicles of leaves on the vegetative stems and because of the numerous sharply pointed involucral bracts in many gradate series. -

Keywords Zyzyura, New Genus, Fleischmannia, Eupatorieae, Belize Introduction The recent description of Fleischmannia mayana Pruski (Pruski and Clase 2012) (Figs. 1, 2) was based on material of a procumbent epilithic herb from the western slope of Victoria Peak in the Cockscomb Range of the Maya Mountains in Belize. The type specimen includes four segments of prostrate stems with ascending flowering branches and accompanying photos of the plants in the field.

There is concern because several factors are impeding its conservation. In this paper, areas of endemism for the flowering plants of Mexico are identified to prioritize regions for conservation. To categorize zones for preservation, the approach followed takes biodiversity, weighted endemism and evolutionary history into account. Lineages of angiosperms, families, genera, and formal or informal groups within genera previously retrieved as monophyletic are selected to represent evolutionary history in equivalent spatial units. -
