Abstract Malvales is a diverse order of flowering plants, economically and ecologically relevant, it known for its broad morphological variability. Recent phylogenomic studies have revealed complex evolutionary history the order, including localised phylogenetic discordances among nuclear loci. However, since late 1990s, classification has largely been neglected. This study aims to address this gap by revisiting Malvales, with focus on largest family, Malvaceae. By integrating datasets, our...
El árbol mopane (Colophospermun mopane) es una especie de la familia Fabaceae típica los ecosistemas del sur África que se encuentra mayoritariamente en Namibia, Zambia y Botsuana. Se diferencia fácilmente otros árboles zona gracias a sus hojas bilobuladas recuerdan las pezuñas jirafas. Tradicionalmente, esta planta son molidas utilizadas por algunas tribus como etnia Himba, para ayudar cicatrización heridas o infusión mujer reponerse parto. Además su madera tienen un sin fin usos,...
Abstract The description of secretory structures in Malvaceae is controversial, and results conflicting interpretations. Amid interpretations, therefore, the present study aims to describe ontogeny diversity histochemistry Ceiba, emphasizing leaves C. erianthos, jasminodora, pentandra, speciosa. All analyzed species mucilaginous, crystalliferous, phenolic idioblasts. These are randomly arranged mesophyll, epidermis, petiole cortex, parenchymatic tissue midrib. However, jasminodora only found...
The present study updates the taxonomy of Quararibea in Atlantic Forest Southeast Brazil. After 130 yr, penduliflora has once again been reported Rio de Janeiro State. A new combination is proposed, Q. angustifolia, and a species, similis, described. Descriptions, species identification keys, illustrations, analysis morphology domatia, aimed at using its diagnostic potential to circumscribe studied here, are provided.
Quararibea bragae from the Atlantic Forest of Espírito Santo State (Brazil) is proposed as a new species. similar to Q. turbinata in vegetative characteristics, such shape and consistency its leaves type domatia. However, it can be distinguished by leaves’ indumentum positioning quantity domatia on abaxial surface leaves. Reproductive characteristics are differentiated staminal tube fruit. We present morphological description comments, illustration, notes ecology distribution, identification key
Abstract In the present study, I propose a new species, Quararibea bovinii, an Atlantic Forest tree. The taxon occurs in southeastern Brazil, states of Espírito Santo, Rio de Janeiro, and São Paulo. It resembles Q. similis terms floral morphology fruit shape, but it is distinguished by indumenta leaves, leaf width, seed shape.
Quararibea floribunda , a species endemic to Brazil, is poorly studied taxonomically, and little known about its ecology conservation status. Since publication in 1842, only few studies have reported on morphological circumscription, thus remaining as complex the taxonomy of . In addition, geographic distribution, which, according most authors, restricted Cerrado Biome, characterized mainly by dry forests. Therefore, we herein review clarify circumscription distribution Q. different...
Ex situ conservation of plants is a current and urgent issue, especially in the Brazilian context. While Brazil has world’s highest plant diversity, few consistent initiatives are aimed at conserving potential our living collections toward reaching Target 8 Global Strategy for Plant Conservation (GSPC). Objective II GSPC calls with specifying 75% threatened species ex collections. It was only after cataloging collection Malvaceae from Rio de Janeiro Botanical Garden (JBRJ) scientific...
A new combination and a status, Pachira manausensis, is here proposed. After making field observations analyzing type herbarium specimens, we realized that P. aquatica var. manausensis should be treated as species due to many morphological distribution differences compared the typical variety. We provide detailed descriptions map, table, key, plate distinguish both using characteristics. Typifications nomenclatural notes for related names were performed.
We describe Catostemma lanceolatum, a new species endemic to the Brazilian Amazon, which at present is known only in state of Amazonas. This taxon similar C. altsonii, mainly by length its pedicels, but can be distinguished shape leaflets, and size bracteoles, hypanthium, number calyx lobes, filaments. morphological description, taxonomic comments, an illustration, distribution map, assessment conservation status, comparative analysis most morphologically species.
We describe Quararibea alversonii, a new species endemic to the Atlantic Forest of southern Bahia, which was found in course our review Brazil. The taxon is similar Q. amazonica, mainly calyx morphology, but it distinguished by presence domatia, pedicel length, petal width, morphology staminal columns and styles, as well fruit shape. Here, we present morphological description, taxonomic comments, photographs, distribution map, assessment conservation status, comparative analysis between only...
