Mancoa perennis, a new species endemic to Michoacán, Mexico is described and illustrated. The new species is similar to M. laxa, but differs in its perennial habit, the caulinar leaf lobes ovate or triangular, entire, apically bearing a branched trichome, and a dense inflorescence with glabrous pedicels.

We describe a new species of Chaunanthus, a small genus of white flowered suffrutescent plants endemic to Mexico. The new species differs from the others because it is glabrous throughout, has winged petioles, and bilobed stigma, with erect lobes. [ABSTRACT FROM AUTHOR]

The aquatic vascular flora and the vegetation of rivers, temporary ponds, dams and ditches of selected localities of the state of Querétaro, Mexico are studied. Several places are heavily infested with water hyacinth (Eichhornia crassipes) and Lemna spp. The highest floristic diversity was found in the temporary ponds of the region of Amealco and Huimilpan where 33 species of aquatic and subaquatic vascular plants were recorded. A total of 118 species of 65 genera and 43 families of pteridophytes, gymnosperms, and angiosperms were found, 19 of which are new state records for Querétaro. [ABSTRACT FROM AUTHOR]

The aim of this research was to contribute information on toxic ornamental plants in Venezuela. Information on taxonomy, common names, habit, origin, status, location, propagation and toxicology (part of the plant, effects) was compiled from articles, books, catalogs, herbarium collections. A botanical analysis (taxonomy, common names, habit, origin, status, location, propagation) and toxicology (part of the plant, effects) was performed. The information about plant poisoning cases was requested to SIMET (Pharmacy faculty -UCV). Seventy-eight species were found in 34 families, the most important were: Apocynaceae (10 genera/12 species), Araceae (9/9), Euphorbiaceae (4/10) and Solanaceae (5/6). Genus Euphorbia was the most species rich. Most species were exotic species (79.5%) and shrubs (32.1%). The entire plant (35) and latex (19) were the most toxic parts and the most frequent accidental ingestion (61.5%). Twenty cases were reported between 2009-2013, of which 80% were minors, female and urban areas. There is very little information published in Hispanic American countries. [ABSTRACT FROM AUTHOR]

Based on the analysis of richness and distribution of strictly aquatic vascular plants, the states most relevant to wetlands conservation of Mexico and its associated flora were identified. A number of 240 species were identified, distributed in 106 genera and 62 families, including 227 native and 13 introduced. Such richness accounts 24% of the total estimated of aquatic plants in Mexico and 8.3% of endemism. The states that have the highest species number are Veracruz (145 species), Jalisco (123), Michoacán (115) and Tamaulipas (113). Iterative analysis points out the need to involve 13 states for the conservation of 100% of the native aquatic flora. [ABSTRACT FROM AUTHOR]
