La familia Bromeliaceae en México

Abstract

<p><strong>Background</strong>: Bromeliaceae family in Mexico has been the object of interest by botanists since 1789; their systematic study was approached from the 1970s onwards, and now there are significant advances in its taxonomic-floristic knowledge.<strong></strong></p><p><strong>Question: </strong>How many and which species of Bromeliaceae occur in Mexico? How they are distributed, and how many are endemic?</p><p><strong>Study site</strong>: México, 1887-2017.</p><p><strong>Methods</strong>: Based on the study of the Mexican Bromeliaceae, including botanical collection, literature review, and revision, analysis and determination of specimens in 50 herbaria, data about species richness, Mexican endemics, and distribution of their taxa in the country, were obtained.</p><p><strong>Results</strong>: In Mexico are represented four of the eight subfamilies of Bromeliaceae, 19 genera, 422 species, and 8 infraespecific taxa. The genera with the highest number of species in the country are <em>Tillandsia </em>(230/54.5 %), <em>Hechtia</em> (71/16.8 %) and Pitcairnia (50/11.8 %). 318 of the Bromeliaceae species are endemics to Mexico, as well as <em>Ursulaea</em> and <em>Viridantha</em> genera<em>; </em>172 species are microendemic. The entity with the highest number of taxa is Oaxaca, followed by Chiapas, Veracruz and Guerrero. Tlaxcala and Baja California Sur have the lowest species number. Baja California, Baja California Sur, Campeche, Ciudad de México, San Luis Potosí, Sonora, Tabasco y Tlaxcala have not strict endemic taxa.</p><p><strong>Conclusion</strong>: Although progress in the knowledge of Mexican Bromeliaceae has been constant, exploration and recollection work is still required before concluding the Mexican bromeliad flora. It is also necessary to promote studies considering aspects of conservation and sustainable use.</p>

Two new species of Hechtia (Bromeliaceae, Hechtioideae) from Oaxaca, Mexico

“…According to Gouda et al (cont. updated), the genus includes 75 species; in Mexico there are 71, 69 of them endemic to the country (Espejo-Serna, 2012;Espejo-Serna & López-Ferrari, 2018), and the state of Oaxaca have the highest number of endemic taxa (17) and also in number of species (28).…”

A novelty in the genus Hechtia (Hechtioideae, Bromeliaceae) from Jalisco, Mexico

“…The Megamexican endemic genus Hechtia comprises 76 species (Espejo-Serna & López-Ferrari 2018). In Mexico 71 species are present, all endemic to the country with exception of H. texensis S. Watson (1885: 374) (Gouda et al, cont.…”

“…In Mexico 71 species are present, all endemic to the country with exception of H. texensis S. Watson (1885: 374) (Gouda et al, cont. updated, Espejo-Serna 2012, Espejo-Serna & López-Ferrari 2018. Up to now, for Jalisco there is a record of 6 species, H. iltisii Burt-Utley & Utley (1993: 222), H. jaliscana L.B.…”

The Reserva de la Biosfera Barranca de Metztitlán (Hidalgo): An illustrated checklist of bromeliads and orchids and their high levels of Mexican endemisms

“…Some previous publications on the Bromeliaceae of Hidalgo (Pintado 2010, Ceja-Romero et al 2010, Hornung-Leoni and Pintado 2011, Hornung-Leoni 2017) have added information about the family in the region, but the present approach is focused on the RBBM. Recent studies in Mexican Bromeliads have documented 442 species for the country and 35 for Hidalgo State (Espejo-Serna and López-Ferrari 2018). On the other hand, Hornung-Leoni (2017) in the Hidalgo Bromeliad flora reports 47 species, ranking it in 8 th position among the richest states for bromeliads species in Mexico.…”
