Populus primaveralepensis A.Vázquez, Muñiz-Castro & Zuno sp. nov., a new species from relict gallery cloud forest in Bosque La Primavera Biosphere Reserve (Mexico), is described and illustrated. The belongs to P. subsect. Tomentosae Hart., morphologically similar luziarum Padilla-Lepe, but differs it having taller trees without root suckers, white ringed young stems branches, branching angle of ca 45º, leaves with higher blade petiole ratio, leafs frequently elliptic or ovate widely (vs...
A new rainforest species of Magnolia from Sierra Santa Marta, Soteapan, Los Tuxtlas, Veracruz, Mexico, is described and illustrated. zoquepopolucae belongs to section Talauma, subsection Talauma. It differs M. mexicana in having fruits spheroidal versus ovoid ellipsoidal, the dorsal wall carpels non humped humped, a larger number stamens, longer petioles, petals sepals, more gradually attenuated petals. The flowers this are used prepare chocolate-like masa (maize)-based hot drink by Zoque...
Magnolia quetzal , a new species from Quiche, Guatemala is described and illustrated; it belongs to section Talauma , subsection ; differs M. morii in having much larger flowers, thinner leaf blades, usually longer petioles larger fruits number of carpels stamens. mayae Huehuetenango here presented as the first record for the Flora Guatemala.
Abandonment of agricultural lands promotes the global expansion secondary forests, which are critical for preserving biodiversity and ecosystem functions services. Such roles largely depend, however, on two essential successional attributes, trajectory recovery rate, expected to depend landscape-scale forest cover in nonlinear ways. Using a multi-scale approach large vegetation dataset (843 plots, 3511 tree species) from 22 chronosequences distributed across Neotropics, we show that...
Secondary succession was studied in a Mexican cloud forest region along chronosequence of 15 abandoned pastures (0.25–80 y). Our objective to determine the effects distance from border on successional vegetation structure and woody species richness chronosequence. Vegetation similar that mature forests recovered over 40–50 y, both close (0–10 m) away (40–50 border. Total for distances but composition differed significantly. When primary were analysed separately, basal area, height, abundance...
The genus Quetzalcoatlia was recently segregated from the paraphyletic Graptopetalum and consists of six species, confined to western Mexico, in states Jalisco, Michoacán Colima (Vázquez-García et al. 2023). alpha-taxonomy (Crassulaceae, Saxifragales) has been summarized below, which includes addition four new species: Q. grulloensis santanamichelii state itzicuaroensis latipetala Michoacán. One species is endemic (Q. glassii); five are Jalisco grulloensis, rosanevadoensis, superba,...
Se describe Magnolia rzedowskiana A. Vázquez, R. Domínguez & Pedraza, un taxon nuevo perteneciente a la sección Macrophylla. distribuye en Sierra Gorda, Querétaro, de Xilitla, San Luis Potosí, y los alrededores Chapulhuacán, Hidalgo, México, bosque mesófilo montaña. asemeja otras especies Macrophylla sus hojas deciduas con envés glauco; comparte dealbata el tamaño árbol hojas, pero difiere esta última por pétalos mucho más angostos, menor número estambres, estilos aplanados, ápice agudo...
Echinoagave nievesiorum (Agavaceae, Asparagales), a new species endemic to the Sierra Wixárika (Huichola), part of Madre Occidental, Jalisco, Mexico, is described. This shares morphological characteristics with rzedowskiana but it differs from latter by having narrower and striate leaves; leaf sheaths shorter, triangular wider at base; ovary width; shorter tube length; tepal lobes anthesis converging tightening filaments; larger filament length flower ratio; fruiting spikes thicker denser...
Background: In western Mexico, the Magnolia pacifica complex includes three morphologically defined, endemic and, endangered species, distributed along a 215 km continentality and moisture gradient: pugana, M. s.s. , vallartensis. 
 Hypothesis: Genetic evidence supports taxonomical classification of complex.
 Study site dates: Western samples were collected in 2012-2015.
 Methods: Six Inter-Simple Sequence Repeats (ISSR) primers amplified 76 clear reproducible fragments 278...
Three new species of Magnolia from lowland tropical rain forests south-eastern Mexico are described and illustrated: chimalapana, M. heribertoi uxpanapana. We contrast these with morphologically similar species. The three endemic to the Chimalapas region evaluated as critically endangered (CR). A map published Chimalapas-Uxpanapa key for Mexican section Talauma also provided.
Recent morphological and phenological data support recognition of Abies jaliscana (Martínez) Mantilla, A. Vázquez & Shalisko at the species level. A key to distinguish from other in western Mexico is provided.
Background: High-severity fires are serious anthropogenic threats to forests, as they can cause forest degradation on unrecoverable scales. Therefore, understanding the patterns and drivers of post-fire regeneration is essential designing restoration proposals. Hypotheses: After a high-severity fire, we expected greater species richness abundance individuals in flat sites than hillside since seeds, nutrients, organic matter accumulate landforms. Compared some Pinus species, Quercus more...
A new species of Magnolia from Chiapas, Mexico is described and illustrated. table morphological characters contrasting Sect. in Chiapas provided. mayae similar to M. grandiflora, but it differs the latter having longer leaves, less coriaceous abaxially glabrous vs densely ferrugineous pubescent; smaller flowers with than half stamens, a number carpels.
Triphora gallegosii, a new species of geophyte orchid known so far from central, western, and northwestern Mexico, is described illustrated. This morphologically similar to T. gentianioides wagneri, with whom it shares the presence scale-like leaves, three longitudinal verrucose lines on lip, floral parts sizes, but differs both by its lip that vanish towards middle central lobe, having 1–4 resupinate flowers, flowering between August September. It also wagneri constricted lobe lateral lobes...
A new species of Magnolia from the rainforest Chiapas, Mexico, is described and illustrated. lacandonica belongs to section Talauma subsection similar M. mexicana, but it differs latter in having larger number carpels stamens, dorsal wall unhumped vs humped, an outer spathaceous bract topped with a reduced leaf blade lacking petals entirely white tinged purple.
Abstract We present a re-evaluation of the taxonomic status Agave gypsophila, for which narrower circumscription is proposed, and four new species from western Mexico are described illustrated: abisaii, A. andreae, kristenii pablocarrilloi . All narrow endemics occurring on variety limestone outcrops belong to subgenus Marmoratae group sensu Berger. They morphologically related gypsophila s. Guerrero, Mexico, but clearly differ it in various qualitative quantitative morphological ecological...
A new species of Magnolia, from the Lagunas de Montebello National Park, in central highlands Chiapas, Mexico, is described and illustrated. Magnolia montebelloensis belongs to section Magnolia; it differs M. poasana its smaller habit, densely pubescent terminal twig internodes, stipules spathaceous bracts, shorter peduncular internodes more numerous stamens. key, an ecological a conservation assessment eight Chiapan Magnoliaceae are included. grows montane rain forest contrasted with other...
