Los ríos son ampliamente afectados por actividades antropogénicas y un ejemplo evidente de este impacto es el río Lerma cual atraviesa centro México. Un tramo denominado “meandro del Lerma” localizado en la zona metropolitana La Piedad-Pénjamo fue aislado cauce natural. Para conocer las condiciones actuales uso suelo su efecto vegetación ribereña, se estudió estructura sus laderas, así como cobertura composición florística mismo. Se observó que tanto asentamientos humanos, agrícolas, los...
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,...
A new species, Echeveria marianae (Crassulaceae) is described from Sierra del Tigre, Valle de Juárez, State of Jalisco, Mexico. The species belongs to ser. Gibbiflorae due its acaulescent or short caulescent rosette habit, paniculiform inflorescence, conical-urceolate corolla, and tricolpate pollen grains. Within it shares morphological affinities with E. novogaliciana dactylifera which differs in the shape, color margin leaves, corolla size color, stamen length, nectaries morphology,...
Cuscuta (dodders) is a group of parasitic plants with tremendous economic and ecological significance. Their seeds are often described as "simple" or "unspecialized" because they do not exhibit any classical dispersal syndrome traits. Previous studies seed morphology and/or anatomy were conducted on relatively few species. We expanded research to 101 species; reconstructed ancestral character states; investigated correlations among characters explored allometric relationships breeding...
The genus Vaccinium contains about 400 species distributed worldwide, but only a few and varieties have had their phenolic composition biological activity documented. In this study, phenols, flavonoids, anthocyanins, antioxidant antimicrobial of methanolic extracts stenophyllum Steud. fruits: 1-totally immature, 2-immature, 3-immature/close to maturity 4-mature, were determined using UV-Visible spectrometry HPTLC. totally immature fruit extract showed the highest content total phenols...
El estudio florístico realizado en el área de la comunidad indígena Nuevo San Juan Parangaricutiro registró presencia 108 familias, con 307 géneros, 716 especies y 16 taxa infraespecíficos, los cuales, 52 son helechos afines, gimnospermas, 120 monocotiledóneas 544 dicotiledóneas. Las familias mejor representadas son: Compositae (135), Leguminosae (58), Gramineae (57), Labiatae (26), Solanaceae (21) Orchidaceae (20) Polypodiaceae (18). 60.7% las corresponden a forma vida herbácea (perenne...

The Cuscuta chapalana complex (Convolvulaceae) is a recently circumscribed clade within the subgenus Grammica that includes several little-known species from Mexico and Central northern South America characterized by presence of peculiar subapical multicelullar appendages on corolla often calyx lobes. Basic morphology, scanning electron microscopy, DNA sequence data plastid trnL–F region 26S rDNA internal transcribed spacer nuclear regions were used to investigate phylogenetic relationships...
Abstract Cuscuta tinctoria clade, the second largest infrageneric group of subgenus Grammica, includes 14 species that are centered in Mexico and adjacent regions, but also two found Australia, presumably as a result long-distance dispersal. Flowers, pollen, stigmas among Cuscuta, with plants being xenogamous or facultatively xenogamous. In this convergent evolution morphological traits, especially those associated calyx gynoecium/ capsule, has obscured identity some hindered previous...
Con base en ejemplares botánicos originarios del estado de Jalisco, México, se propone como especie nueva para la ciencia, describe e ilustra a Echeveria patriotica (Crassulaceae). Este taxon por llevar tallo, láminas foliares angostas forma pseudopeciolo, inflorescencia paniculiforme con raquis alargado, más tres ramificaciones y corola cilíndrico-urceolada, 13 mm largo, ubica serie Gibbiflorae (Baker) A. Berger. Del conjunto especies involucradas este grupo tiene semejanza E. grisea...
Se describe e ilustra Echeveria purhepecha (Crassulaceae) como especie nueva para la ciencia. Por sus características morfológicas, se ubica en serie Retusae E. Walther. Dentro del grupo, presenta mayor similitud con fulgens Lem., especialmente var. obtusifolia (Rose) Kimnach, de que difiere por las hojas más cortas, longitud inflorescencia menor, menor número flores cincino, pedicelo y segmento cáliz largos, corola rojo escarlata, segmentos oblongo-lanceolados.
Eryngium es uno de los géneros más extensos y con mayores dificultades taxonómicas entre las Apiaceae. El grupo incluye 230 a 250 especies distribuidas en regiones templadas tropicales del planeta. Para México se han registrado alrededor 60 especies, 21 ellas existen el estado Michoacán. Éstas distribuyen cinco tipos vegetación, pero principalmente lo hacen pastizal, bosques pino-encino coníferas. Se una clave para la determinación citadas.
Abstract A new species, Echeveria pistioides (Crassulaceae) is described from south of Morelia in the State Michoacan, Mexico. The species belongs to ser. Gibbiflorae due its short or acaulescent stems inconspicuous among large basal leaves rosettes, paniculiform inflorescence, conical-urceolate corolla, and tricolpate pollen grains. Within Gibbiflorae, closest morphological affinities E. are with marianae which it differs glaucous a different shape size, fewer cincinni, smaller flowers,...
A new species, Echeveria coruana, is described and illustrated from the malpaís near San Andrés Corú, Michoacan, Mexico. The species belongs to series Gibbiflorae taxon was compared with E. purhepecha patriotica, whom it shares closest morphological affinities. Additionally, yalmanantlaensis an endangered Sierra of Manantlán Biosphere Reserve, State Colima, also discovered Corú reported for first time Michoacan. conservation status both (re)evaluated according criteria International Union...
Se describe y propone como especie nueva para la ciencia a Pachyphytum contrerasii (Crassulaceae). el nuevo taxon se ubica en sección Moran, por llevar las brácteas imbricadas cincino joven, tener corola más corta que cáliz presencia de una mancha roja evidente cara interna los segmentos corola. La semejante morfológicamente es P. machucae I. García, Glass et cházaro, cual difiere diversos caracteres flor, tales como: largo del pedicelo, relación entre coloración pétalos, estambres pistilo.
