Two new marine species of Cocconeis (Bacillariophyceae) from the west coast of Sweden
European Journal of Taxonomy 497, 2019

Abstract
This paper is part of a project of studying benthic diatom biodiversity on marine coastal regions of Sweden with focus on rare and less known species. Two new species of Cocconeis Ehrenb. are described from Vrångö, a small island in the west coast of Sweden. Both species were found as epiphytic on the green alga Ulva intestinalis L. Cocconeis magnoareolata Al-Handal, Riaux-Gob., R.Jahn & A.K.Wulff sp. nov. is a small species not exceeding 9 µm in length and characterized by having large subquadrangular areolae on the sternum valve. Cocconeis vrangoensis Al-Handal & Riaux-Gob. sp. nov. appears similar to some taxa of the ‘Cocconeis scutellum complex’, but differs by its stria density on both valves and variable features of the areola and valvocopula ultrastructure. Detailed descriptions based on light and electron microscopy examination, a comparison with closely related taxa, as well as a description of the habitat of both species are here presented.

Populus primaveralepensis sp. nov. (Salicaceae, Malpighiales), a new species of white poplar from the Bosque La Primavera Biosphere Reserve in western Mexico.
European Journal of Taxonomy, No 498 (2019)

Abstract

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 new species belongs to P. subsect. Tomentosae Hart., and is morphologically similar to P. luziarum A.Vázquez, Muñiz-Castro & Padilla-Lepe, but differs from it in having taller trees without root suckers, white and ringed young stems and branches, a branching angle of ca 45º, leaves with higher blade to petiole ratio, leafs frequently elliptic or ovate to widely ovate (vs widely ovate to ovate-deltoid), denser inflorescences, and shorter capsules. The conservation status of the species was assessed as Critically Endangered (CR).

Stenocereus huastecorum

The Stenocereus griseus species complex (SGSC) has long been considered taxonomically challenging because the number of taxa belonging to the complex and their geographical boundaries remain poorly understood. Bayesian clustering and genetic distance-based methods were used based on nine microsatellite loci in 377 individuals of three main putative species of the complex. The resulting genetic ...

Marsdenia stevensiana (Apocynaceae, Asclepiadoideae), a New Species from Chiapas, Mexico

Verónica Juárez Jaimes
(Novon: A Journal for Botanical Nomenclature 24(2):170-172. 2015).
Abstract:
" ... It is distinguished by a fleshy, semicircular, papillose, and glabrous callus in each sinus of the corolla lobes, and this callus extends along the base of each lobe forming a continuous corona on the throat of the corolla. The morphological characteristics of this new taxon are different from those of the 31 species of Marsdenia R. Br. known from Mexico. The new species resembles M. mayana Lundell and M. pseudoedulis Woodson, with which it is compared."
