Se describe e ilustra Tillandsia magnispica Espejo & López-Ferrari, conocida sólo del estado de Oaxaca, México, en los municipios de San Pedro el Alto y San Pedro Pochutla. La nueva especie se compara con T. jaliscomonticola matuda, con la cual tiene afinidades morfológicas

Oaxaca is one of the Mexican states with highest plant species richness, hosting about 10,000 taxa of vascular plants. The Bromeliaceae family is represented in Oaxaca by 184 species, which corresponds to 44% of the Mexican bromeliad flora. About 29% (53 spp.) and 67% (124 spp.) of these species are endemic to the state and to the country, respecti...
Based on morphological evidence, we propose to raise Tillandsia mauryana forma secundifolia to species level with the name Viridantha secundifolia (Ehlers) Hern.-Cárdenas, Espejo & López-Ferr. Viridantha secundifolia can be readily distinguished by the falciform rosettes, the broadly oblong to square, 1-1.2 × 0.8-1.1 cm leaf sheaths and by the 1.8-...
Hechtia ibugana a new species from the municipality of Puerto Vallarta, Jalisco, is described and illustrated. The new taxon is compared with H. pretiosa and H. rosea, species that also present sepals and petals rose to reddish, as well as with H. iltisii and H. santanae, endemic species of the state of Jalisco, Mexico.

p> Background : 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.
Question: How many and which species of Bromeliaceae occur in Mexico? How they are distributed, and how many are endemic?
Study site : México, 1887-2017.
Methods : 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.
Results : 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 Tillandsia (230/54.5 %), Hechtia (71/16.8 %) and Pitcairnia (50/11.8 %). 318 of the Bromeliaceae species are endemics to Mexico, as well as Ursulaea and Viridantha genera ; 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.
Conclusion : 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
