A new combination in Entada (Leguminosae) from Roraima, Brazil
Entada simplicata, formerly recognized as a variety of E. polystachya, is reinterpreted as a distinct legume species, based on consistent differences regarding their leaves (number of pairs and width of leaflets), and fruits (mesocarp presence, stipe and funiculus length). Illustrations and a distribution map are provided for E. simplicata, which is endemic to Roraima State, northern Amazonia, ...
متن کاملA NEW ALKALOID FROM FLOWERS OF ERYTHRINA STRICTA
The alkaloids present in the flowers of Erythrina stricta have been isolated and characterized by spectroscopic methods. A new alkaloid 11-acetyl erysotrine has been isolated and its structure established by spectral studies (UV, IR, 1H NMR and HRMS).
متن کاملLeaf CO(2) exchange of Erythrina poeppigiana (Leguminosae: Phaseolae) in humid tropical field conditions.
An idealized model was developed to describe leaf CO(2) exchange in the leguminous tree Erythrina poeppigiana (Walpers) O.F. Cook under well-watered field conditions. Photosynthetic rate in mature leaves (p) was modeled as a rectangular hyperbolic function of photon flux density (q) and ambient CO(2) concentration (c(a)), relative photosynthetic capacity (pi) was modeled as a logistic s-functio...
متن کاملErythrina speciosa (Leguminosae-Papilionoideae) under soil water saturation: morphophysiological and growth responses.
BACKGROUND AND AIMS Erythrina speciosa is a Neotropical tree that grows mainly in moist habitats. To characterize the physiological, morphological and growth responses to soil water saturation, young plants of E. speciosa were subjected experimentally to soil flooding. METHODS Flooding was imposed from 2 to 4 cm above the soil surface in water-filled tanks for 60 d. Non-flooded (control) plan...
