Begonia chucantiensis sp. nov. is described as a new species of section Lepsia from Cerro Chucantí, Darién Province, in eastern Panama. A study the literature and herbarium specimens, well fieldwork, suggests that taxon distinguished other by combination following characters: uniform nodes, stipules persistent, 3.3–6 × 0.8–1.7 cm leaf blades, only two flowers per inflorescence, 12–14 stamens, fruits with wings similar shape size. Images, information on geographic distribution, habitat,...
ABSTRACT Although inselbergs from around the world are iconic ecosystems, little is known on underlying mechanisms of community assembly, especially in their characteristic patchy outcrop vegetation. Environmental constraints expected to cause phylogenetic clustering when ecological niches conserved within evolutionary lineages. We tested whether vegetation patches rock outcrops Piedra La Tortuga Natural Monument, northern Amazon region, phylogenetically clustered, indicating that...
In the present study, we report 46 new records of vascular plants species from Panama. The belong to following families: Anacardiaceae, Apocynaceae, Aquifoliaceae, Araceae, Bignoniaceae, Burseraceae, Caryocaraceae, Celastraceae, Chrysobalanaceae, Cucurbitaceae, Erythroxylaceae, Euphorbiaceae, Fabaceae, Gentianaceae, Lacistemataceae, Lauraceae, Malpighiaceae, Malvaceae, Marattiaceae, Melastomataceae, Moraceae, Myrtaceae, Ochnaceae, Orchidaceae, Passifloraceae, Peraceae, Poaceae,...
Abstract After discovering an unknown Euphorbiaceae with unusual combination of morphological characters, molecular phylogenetic analyses were conducted to evaluate the position plant. Results support recognition a resolved lineage sister clade comprising Caryodendron , which is Adenophaedra + Bernardia in subfamily Acalyphoideae. The this taxon also supported by morphology, justifying description new genus and species, Bahiana pyriformis from Caatinga seasonally dry forest, Bahia State,...
This work describes and illustrates Bernardia hamadryadica, from the Chapada Diamantina, in northeastern Brazil. The new species is distinguished other of genus by combination following characters: shrubby habit; young leaves inflorescences usually produced on short shoots; membranaceous leaf laminas less than 6 cm long, with disk-shaped, slightly prominent glands abaxial surface; spiciform staminate up to 1 long; entire style branches; indumentum simple trichomes.
Bernardia fluviatilis is described as a new species of Euphorbiaceae from the Upper Paraguay River Basin in central South America. A literature review, examination herbarium specimens, and fieldwork suggest that taxon most similar to B. argentinensis but differs by its young branches covered sparsely sericeous indumentum simple trichomes, usually shorter staminate peduncles, cymules scattered along axis inflorescence, flower pedicel glabrous. Illustrations, photographs, information about...
Abstract— A new species of Bernardia with stellate trichomes from the Brazilian Cerrado is described and illustrated. allemii most similar to B. gardneri , but differs by its multi-stemmed, subshrub habit, broader leaf blades, tomentose old branches, staminate bracteoles that are usually reniform flabellate, larger sepals bracts in pistillate flowers. Photographs, a distribution map, information about conservation status species, key Brazil also provided.
Pleradenophora membranifolia (Müll. Arg.) Esser & A.L. Melo (Euphorbiaceae) was previously only known from central South America (Bolivia, Brazil, and Peru). Our new botanical collections the seasonal dry forests in Garachiné, Darién Province, Panama increase distribution of this species to Central include first record genus for country. We also provide photographs field herbarium specimens, an occurrence map, a description, comments on...
Abstract Road networks cause disturbances that can alter the biodiversity and functioning of Caatinga ecosystems. We tested hypotheses (i) vegetation near roads is less taxonomically, functionally phylogenetically diverse, (ii) more clustered than further from roads, (iii) plant traits associated with herbivory deterrence are conserved within phylogenetic lineages, (iv) selects for disturbance-related traits. sampled herbaceous woody component in four plots to test these hypothesis. Sampled...
