Three new species of Myrtaceae from Querétaro and Hidalgo, México are described and illustrated: Calyptranthes moctezumae, Eugenia queretaroana and E. huasteca. Calyptranthes moctezumae is related with C. schlechtendaliana and C. schiedeana, from which it is distinguished by the lesser number of nerves per leaf, petioles 1 to 5 mm long, and because...

Myrtaceae family for Bajío flora and Adjacent Regions

129 currently accepted names (all continental American Calyptranthes, but six also occurring in the Caribbean) are here transferred to Myrcia, a required step towards a new classification of the Myrcia s.l. group supported by molecular phylogenetic and morphological studies. Geographical distribution is indicated for each species.

Dicranocarpus is a monotypic genus endemic to the Chihuahuan Desert with atypical attributes among species of tribe Coreopsideae. Phylogenetic position of Dicranocarpus parviflorus has been controversial. A molecular phylogeny showed that the taxon was closely related to Dahlia; however, further analyses with a wider sampling of Dahlia, also includ...

A number of morphological vegetative, floral, pollen, and fruit characters differ between the taxa of Dahlia and Hidalgoa. This study compares morphological and anatomical characters of the cypselae in Dahlia and Hidalgoa, identifying variations of potential taxonomic value to assess whether they should be treated as independent taxa. Cypselae of t...

Hidalgoa and Dahlia are two closely related genera in Asteraceae, tribe Coreopsideae whose limits need to be clarified. Pollen morphology has been useful for delimitation at the genus level in this family. To better define these genera, the morphology of pollen grains was observed and measured using light and scanning electron microscopy. The polle...

Eugenia harkerae is here described as new from Jalisco, Mexico. It is morphologically similar to E. oerstediana and E. turneri; however, it differs by its pubescent branchlets with brownish hairs, uniflorous pendant inflorescences, peduncles of 1.5–3 cm long, and glabrous hypanthia.

Familia de distribución tropical, con 140 géneros y ca. 7000 especies a nivel mundial. En México se registran 10 géneros y aproximadamente 113 especies; en el Bajío y regiones adyacentes se encuentran cuatro géneros y 14 especies nativas más una variedad; no se incluyen Eucalyptus camaldulensis, E. globulus, E. robusta, Callistemon citrinus, C. rig...
