“…In addition, a single pistillate flower was found on a primarily staminate plant of B. trelawniensis, and it is known that monoecy occurs in Bernardia but not in Lasiocroton (Radcliffe-Smith, 2001;Webster, 1994). Our initial morphological observations for Bernardia were supplemented by those provided by Radcliffe-Smith (2001) and Cervantes et al (2003). We also found additional morphological characters that show that this taxon belongs to Bernardia (Table 1).…”

Lasiocroton trelawniensis (Euphorbiaceae), a critically endangered species from the Cockpit Country of Jamaica, belongs to Bernardia (Euphorbiaceae). Botanical Review Vol. 74, No., 1 2008.-A taxonomic study based on scanning electron microscopy of pollen, macro-morphology, and a molecular phylogenetic analysis of the chloroplast DNA regions trnL-F and rbcL shows that Lasiocroton trelawniensis belongs to the Neotropical genus Bernardia. The main morphological differences between Bernardia and Lasiocroton are given, and the new combination Bernardia trelawniensis is provided.Resumen Un estudio taxonómico basado en microscopía electrónica de barrido del polen, en macro-morfología, y en análisis filogenéticos moleculares de las regiones del ADN de los cloroplastos trnL-F y rbcL muestra que Lasiocroton trelawniensis pertenece al género neotropical Bernardia. Se dan las principales diferencias morfológicas entre Bernardia y Lasiocroton y se da así mismo la nueva combinación Bernardia trelawniensis.

“…Likewise, the pollen opercula of all of the Leucocroton species are wider and more pronounced than the other genera, with the single exception of Lasiocroton microphyllus ; a species that exhibited a unique mosaic of character traits also found in the other two genera. The pollen of Adelia cinerea (shown by Cervantes & al., 2003) has a similar operculum and shape to Garciadelia, though the perforations are not as dramatic.…”

The Caribbean Island Biodiversity Hotspot is the largest insular system of the New World and a priority for biodiversity conservation worldwide. The tribe Adelieae (Euphorbiaceae) has over 35 species endemic to this hotspot, representing a prime example of speciation in the West Indies and involving taxa from Cuba, Hispaniola, Jamaica, and the Bahamas. These species form a monophyletic group and have traditionally been accommodated in two endemic genera, Lasiocroton and Leucocroton. A study based on scanning electron microscopy of pollen, macromorphology, and molecular analysis was conducted to reveal generic relationships within this group. Phylogenies were based on nucleotide sequences of the nrITS region and the non‐coding cpDNA spacers psbM‐trnD and ycf6‐pcbM. Three major monophyletic assemblages were revealed; one of them is restricted to Hispaniola and is accommodated in a new genus, Garciadelia, with four species. The new genus is sister to a clade comprising two monophyletic groups, one including all species of Leucocroton and restricted to serpentine soils of Cuba, and a second including the species of Lasiocroton, occurring in Cuba, Hispaniola, Jamaica, and the Bahamas. Morphological, biogeographical, and ecological data provided additional support for each of these three monophyletic assemblages. Two new combinations (Lasiocroton microphyllus from Cuba, Garciadelia leprosa from Hispaniola) are made and four new species are described (Lasiocroton gutierrezii from Cuba, and Garciadelia abbottii, G. castilloae, and G. mejiae from Hispaniola).

“…Govaerts et al . (2000) listed 21 Mexican species of Bernardia , but during a monographic study of the Mexican species of the genus (Cervantes, 2002), several taxonomic changes were undertaken (Cervantes, 2002; Cervantes, Steinmann & Flores, 2003). In addition, in the same study several new taxa were proposed, six of which are described here (see also Cervantes & Jiménez Ramírez, 2002).…”

Six new species of Bernardia from Mexico are described and illustrated. Species are distinguished by a combination of characters such as habit, leaf shape and size, indumentum, venation pattern, gland position, length of staminate inflorescence, number of bracts, number of flowers per bract, size of bracts and tepals, number of stamens, style type, fruit dehiscence, size, pubescence, trichome type, endocarp texture, seed shape, size and ornamentation, raphe length and micropyle position. Bernardia macrocarpa belongs to section Alevia ; B. chinantlensis to section Polyboea , which is recorded for the first time in Mexico; B. chiangii , B. mcvaughii , B. rzedowskii and B. valdesii belong to section Tyria , which is the most diverse section in Mexico. With the recognition of these six new species, Mexico becomes the area with the highest diversity for Bernardia .
