The infraspecific taxonomy of wild Anacardium occidentale is little studied. We investigated
whether wild populations on coastal dunes in Piau{\i}, 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 were mostly more similar to one another than to
domesticated ones. There was significant correlation between inter-population geographical
distance and morphological dissimilarity. Classification methods showed 96.4\% successful
assignment to the dune category and 86\% to 100\% to dune populations
individually, but dune and non-dune populations overlap morphologically. Dune populations
had shorter, broader leaves, shorter drupes and fewer secondary veins. Non-dune coastal
populations showed strongest similarity to dune populations. Populations distant from the
coast were most divergent. The population from the cerrado region was most distinct, with
thicker leaf blades and narrower petioles. The dune populations are recognised as the
\“restinga ecotype\” of A. occidentale. Correlation of dissimilarity and distance may result
from gene flow and/or non-inherited environmental effects. Ecology and nomenclature (including
the vernacular \“caju{\i}\”) of the restinga ecotype are reviewed. Further comparison of
restinga populations is needed along the Brazilian coastline and with natural cerrado populations.

Anacardium microcarpum (caju\í) differs from A. occidentale (cashew) by its smaller drupe and hypocarp and more restricted range in cerrados and coastal plateaux of Brazil\’s Par\á, Maranh\ão, Piau\í, Cear\á and Rio Grande do Norte states. Taxonomists treat A. microcarpum as conspecific with A. occidentale, but many agronomists treat it as distinct. This study used geometric morphometrics to investigate leaf shape differences between the two taxa in ten populations from coastal Piau\í state, Brazil with samples of 300\–380 leaves. Configurations of two landmarks and 14 semilandmarks were digitized along the leaf outline from standardized images and subjected to multivariate analysis after Procrustes alignment. Principal component analysis produced four significant principal component shape variables accounting for 79.5 \% total variance. These were visualized using thin-plate spline analysis. Discriminant analysis showed a significant difference between the taxon means (P = 0.003). Jackknife cross-validation correctly classified only 61.3 \% of A. occidentale individuals and 56.7 \% of A. microcarpum. Non-Parametric MANOVA of the ten populations showed significant population differences (P = 0.0001). The most isolated population (Cocal da Esta\ç\ão)\—the only one from the interior of the state\—differed most. A Mantel test found no significant correlation between morphological dissimilarity and geographical distance. Although leaf shape differences both between taxa and populations were statistically significant, overlap made leaf shape difference alone ineffective for separating A. microcarpum from A. occidentale.
