En este avance de la revisión taxonómica que se adelanta para el género Quararibea (Malvaceae) del norte de Sudamérica, se describen tres especies nuevas que se comparan morfológicamente con las especies afines en cada caso. La primera especie, Q. cornejoi, conocida de los bosques muy húmedos del Occidente de Ecuador, la asociamos con Q. grandifoli...
Environmental gradients are important factors that can potentially influence the genetic diversity and differentiation of populations. The present study examines the effect of environmental heterogeneity of the Hyrcanian forests on populations of Circaea lutetiana L. (Onagraceae). Using morphometrics, scanning electron microscopy (SEM) of leaf epid...
After examination of specimens, mainly from the herbarium (MA) and the mycological collection (MA-Fungi) of the Royal Botanic Garden of Madrid, we report several novelties on smut fungi within Europe. Two species of smut fungi, Sporisorium egyptiacum and Tilletia viennotii, are reported for the first time from Europe. A finding of Sphacelotheca pol...
The genus Xanthoparmelia is the largest genus of lichen- forming fungi with about 800 species worldwide. Xanthoparmelia is also common in the deserts of central Mexico, but only a few molecular studies exist on its species’ diversity in this region. In this study, we sampled 38 Xanthoparmelia species from around the world including species from the...
Parasopubia raghavendrae, a new species of Orobanchaceae is described from the southern Western Ghats of Kerala. It resembles P. delphinifolia and P. hofmannii var. hofmannii by its habit, shape, colour and hairiness of corolla lobes but differs by length of calyx tube, hairiness of staminal filaments and stomium, and shape and ornamentation of see...
De acuerdo con la revisión exhaustiva del material original y los protólogos, así como el estudio de cuantos especímenes tuvimos a nuestra disposición, la especie Senecio gonocaulos DC. se transfiere al género Pentacalia y el nombre P. poeppigiana A.Granda se incluye en la sinonimia de la misma. Además, se designa un lectótipo para S. gonocaulos y ...
A new species of Henckelia (Gesneriaceae) is here described and illustrated. It is morphologically most similar to H. oblongifolia but differs in having lanceolate calyx lobes, two prominent longitudinal flaps on the inner surface of the corolla tube, bilobed stigma and tomentose capsules. A detailed description of the new species with colour photo...
El nombre Croton moschatus Monteverde & P.Betancourt, previamente ignorado, es reconocido aquí para una especie endémica de Cuba sobre la base de que fue válidamente publicado y porque tiene prioridad sobre los sinónimos heterotípicos C. claraensis Urb. y C. sagranus Müll. Arg. En este trabajo se designa un neótipo para el nombre C. moschatus y le...
Here, we describe and illustrate a new alpine species of Astragalus sect. Anthylloidei from Iran. Astragalus wiesneri sp. nov., an interesting and rare species, is only known from the type locality in the Bul Mountain (near Eghlid city) in the southern Zagros Mountains. The new species is compared with close relatives, including A. nigrohirsutus an...
Lichens, as well as other organisms, should be considered important biodiversity components for the establishment of priorities in conservation biology. In this study, we report six new recent localities of the highly endangered, epiphytic macrolichen Pseudocyphellaria aurata in Spain: two in Navarra and four in A Coruña. Previous Spanish reports b...
