A morphometric study of the restinga ecotype of Anacardium occidentale (Anacardiaceae): wild coastal cashew populations from Piauí, Northeast Brazil
The infraspecific taxonomy of wild Anacardium occidentale is little studied. We investigated whether wild populations on coastal dunes in Piauí, Brazil differed from non-wild populations. Ten populations were sampled and twenty one morphological variables were measured. Variation within and between populations was investigated with univariate and multivariate statistics. Dune populations...de Andrade, I ; de Oliveira, Nascimento ; de Sousa, M ; dos Santos, J ; Mayo, S

‘Unknown yellow’: Pibiria, a new genus of Passifloraceae with a mixture of features found in Passifloroideae and Turneroideae
In 1993, a shrub with yellow flowers reminiscent of but obviously distinct from Turnera was found near Mabura Hill in central Guyana, which was recollected in 2000. This paper offers a morphological description including leaf and wood anatomy and pollen morphology in addition to a phylogenetic analysis based on plastid...Maas, Paul ; Baas, Pieter ; Christenhusz, Maarten ; Clarkson, James ; Koek-Noorman, Jifke …
