“…Recognition of six species of Reinhardtia (Moore, 1957;Read, Zanoni, and Mejía, 1987) is supported by this study. The species are clearly distinguished from one another based on both quantitative variables and qualitative characters.…”

“…Discriminant analysis was carried out using the same set of specimens and variables, with the six species recognized by Moore (1957) and Read, Zanoni, and Mejía (1987) as group- Results of PCA and CA indicate that specimens form six groups, with little overlap between them, corresponding to the six previously recognized species. Discriminant analysis shows that specimens can be classified with 100% success based on quantitative variables.…”

“…The ingroup contains the six species recognized by Moore (1957) and Read, Zanoni, and Mejía (1987). Twelve characters were used in this analysis (Appendix 1), taken from Moore (1957), Read, Zanoni, and Mejía (1987), and from examination of specimens. The data matrix was constructed and edited with Winclada (Nixon, 1999).…”

Principal component analysis and cluster analysis of morphometric data divide specimens of Reinhardtia into six groups, corresponding to the six species recognized in the most recent revisions. Discriminant analysis classifies specimens into these six species with 100% success. Five species occur in lowland to montane moist forests in Central America, from Mexico to Panama, and just reach Colombia; one species occurs in montane moist forests in Hispaniola. Three species have large stems and are rare, patchily distributed, and seldom collected. The other three species have small stems, are common and frequently collected, but also patchily distributed. One species of small plants, R. gracilis, exhibits considerable variability. Within this species, seven distinct groups can be recognized, although sample size is limited. Among species, there is a phyletic decrease in size of plants, from the basal species with large stems to derived species with small stems. For leaves and inflorescences there is also an associated decrease in size, but one species does not follow this trend. In this species, R. latisecta, there is evidence of a large ontogenetic change in leaf development. Phyletic decrease in size corresponds to a latitudinal and elevational gradient suggesting speciation has taken place from north to south and from high to low elevation. However, this pattern is obscured disjunct distributions in some species.

“…Con base en los criterios propuestos por Rabinowitz (1981) y la información disponible hasta el momento, R. elegans es una palma rara, ya que presenta una distribución geográfica muy restringida, una estrecha amplitud ecológica y posiblemente un reducido número de poblaciones, situación que comparte con R. paiewonskiana (Read et al, 1987). A pesar de que no hemos generado información que documente de manera precisa la distribución y abundancia de R. elegans en el área de Santo Domingo Lataní, los datos proporcionados por los habitantes locales indica que esta especie cuenta con escasas poblaciones, muy distantes entre sí.…”

“…La distribución del género es fundamentalmente mesoamericana, aunque de acuerdo con Henderson et al (1995), dos especies se han encontrado en el noroeste de Colombia (Cuadro 1). Reinhardtia paiewonskiana es la única presente en el área antillana, a la cual se encuentra restringida (Read et al, 1987;Henderson, 2002). En México se han registrado tres especies que muestran una distribución hacia la vertiente atlántica del sureste del país: R. elegans (Chiapas y Oaxaca), R. gracilis (Chiapas, Oaxaca, Tabasco y Veracruz) y R. simplex (Chiapas), esta última citada recientemente para la región Lacandona, Chiapas, por Martínez et al (1994).…”

RESUMENSe registra la presencia de Reinhardtia elegans Mart. (Arecaceae), una palma endémica de algunos bosques mesófilos de montaña de Oaxaca y Chiapas, cuya importancia no ha sido debidamente resaltada en los trabajos florísticos del sureste de México. Se aporta información sobre algunos aspectos del hábitat y estructura poblacional de la especie en la región de La Chinantla, Oaxaca, México.Palabras clave: Arecaceae, bosque mesófilo de montaña, Chiapas, México, Oaxaca, palmas, Reinhardtia.ABSTRACT Reinhardtia elegans Mart. (Arecaceae) is a Mexican endemic species occurring in some cloud forests of Oaxaca and Chiapas, whose importance has been poorly documented in floristic studies of southeastern Mexico. We provide information about its habitat and population structure in La Chinantla region in Oaxaca, Mexico.

Molecular Phylogenetic Studies of Caribbean Palms (Arecaceae) and Their Relationships to Biogeography and Conservation

The Caribbean Islands are one of the world's 34 biodiversity hotspots, remarkable for its biological richness and the high level of threat to its flora and fauna. The palms (family Arecaceae) are well represented in the West Indies, with 21 genera (three endemic) and 135 species (121 endemic). We provide an overview of phylogenetic knowledge of West Indian Palms, including their relationships within a plastid DNA-based phylogeny of the Arecaceae. We present new data used to reconstruct the phylogeny of tribe Cryosophileae, including four genera found in the West Indies, based on partial sequences of the low-copy nuclear genes encoding phosphoribulokinase (PRK) and subunit 2 of RNA polymerase II (RPB2). Recently published phylogenetic studies of tribe Cocoseae, based on PRK sequences, and tribes Cyclospatheae and Geonomateae, based on PRK and RPB2 sequences, also provide information on the phylogenetic relationships of West Indian palms. Results of these analyses show many independent origins of the West Indian Palm flora. These phylogenetic studies reflect the complex envolutionary history of the West Indies and no single biogeographical pattern emerges for these palms. The present day distributions of West Indian palms suggest complicated evolutionary interchange among islands, as well as between the West Indies and surrounding continents. We identified six palm lineages that deserve conservation priority. Species-level phylogenies are needed for Copernicia, Sabal, and Roystonea before we can build a more complete understanding of the origin and diversification of West Indian palms.Resumen Las Islas del Caribe constituyen uno de los 34 "hotspots" de biodiversidad del mundo, notables por su riqueza biológica y el alto grado de amenaza de su flora y fauna. La familia Arecaceae esta bien representada en Las Antillas con 21 géneros (tres endémicos) y 135 especies (121 endémicas). Presentamos una síntesis del conocimiento filogénetico de las palmas de Las Antillas incluyendo su posición dentro de la filogenia de la familia Arecaceae basada en ADN cloroplástico. Construímos una nueva filogenia para la tribu Cryosophileae, Bot. Rev. (2008) 74:78-102
