A new species of Guadua from the Atlantic forest in Argentina, variegata, is described and illustrated.Guadua variegata compared to other taxa distributed Bolivia, Paraguay, Uruguay, southern Brazil a key table based on exomorphological characters.Additional micromorphological characters foliage leaf blades cauline epidermis G. are included.Lectotypes paniculata tessmannii here designated.Resumen-Se describe e ilustra una nueva especie propia de la selva misionera Argentina.Guadua es...
Abstract The taxonomic status of Panicum sect. Tuerckheimiana and Valida has remained as “incertae sedis” within . To resolve the systematic position both sections Paniceae s.l., morphological studies phylogenetic analyses based on chloroplast sequence data ( ndhF ) were conducted. Our study shows that are included in subtribe Paspalinae tribe Paspaleae, where they related with genus Anthaenantiopsis These results support recent transfer these species to recently described genera Aakia...
The New World genus Heterosperma Cav. is circumscribed to include 11 species: H. achaetum S. F. Blake, diversifolium Kunth, ferreyrii Rob., mexicanum (A. Gray ex Watson) Lizarazu & E. Freire, nanum (Nutt.) Sherff, ovale ovatifolium Cav., pinnatum spathulatum tenuisectum (Griseb.) Cabrera, and trilobum Blake. described as having a usually herbaceous habit, pinnatisect or entire leaves, radiate capitula, heteromorphic cypselae. following taxa are newly synonymized: Coreopsis L. sect....
The genus Bidens L. is the largest of Coreopsideae that comprises about 280 species with a global distribution in tropical and temperate climates. An account 12 three varieties occurring Bolivia provided, i.e., B. andicola Kunth var. andicola, heterophylla Kuntze, aurea (Aiton) Sherff, cynapiifolia Kunth, exigua gardneri Baker, herzogii (Sherff) D. J. N. Hind, mandonii Cabrera, pilosa L., pseudocosmos squarrosa subalternans DC. subalternans, simulans tenera O. E. Schulz, triplinervia...
The genus Heterosperma (Asteraceae, Coreopsideae) currently comprises ten species distributed from Mexico to South America. Molecular phylogenies of the tribe Coreopsideae (including only two Heterosperma) pointed out that would not be monophyletic. A molecular phylogenetic analysis including seven and related taxa, using plastid nuclear sequences, was performed. results indicated is monophyletic if Coreopsis cyclocarpa included. As a result, new combination, mexicanum, proposed....
Summary: Chusquea juergensii (Poaceae, Bambusoideae, Bambuseae), new record from Argentina. is here reported for the first time It described and illustrated, a map of its geographical distribution in South America included. In north-east Argentina ramosissima C. tenella are also present sympatry with juergensii. A key identification three taxa that inhabit provided.Key words: Bambuseae, Chusquea, northeastern Argentina, taxonomy.Resumen: se cita por primera vez para la especie describe e...
La floracion de un bambu es evento particular. El registro la una mata o poblacion aporta datos precisos sobre los ciclos biologicos. Bambusa tuldoides especie endemica China y esta ampliamente cultivada en todo el mundo. En Argentina, primera referencia su cultivo 1943. No se han registrado fructificaciones Argentina. Registramos ejemplar B. recolectamos otros eventos Argentina paises limitrofes. Con informacion, estimamos ciclo America austral 23 anos aproximadamente. produccion frutos...
The genus Gloxinia (Gesneriaceae, Gesnerieae, Gloxiniinae) comprises four species distributed from Nicaragua to Argentina. Historically, Koellikeria major has been problematic place taxonomically due the morphological similarity with erinoides, and as a result is currently treated synonym. Here, we present molecular phylogenetic study that allowed us demonstrate distinct G. erinoides. As result, formally transfer major. Here described, illustrated, compared morphologically similar species....
