The infraspecific taxonomy of wild Anacardium occidentale is little studied. We investigated
whether wild populations on coastal dunes in Piauı, 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 “cajuı”) of the restinga ecotype are reviewed. Further comparison of
restinga populations is needed along the Brazilian coastline and with natural cerrado populations.

Knowledge of medicinal plants has accumulated over centuries and often represents the only
therapeutic resource of small municipalities in the interior of Brazil. The objective of this study was to
evaluate the knowledge and use of medicinal plants by the population of the municipality of Bom
Princípio do Piauí, Piauí state, for the treatment of diseases in humans and domestic animals.
Interviews were conducted with 38 residents using standardized questionnaire forms, with the
"snowball" technique. Fifty nine families, 98 genera and 112 species were recorded. Of these, 22.3%
were indicated for the treatment of diseases in animals and 9.8% were said to cause adverse effects.
The families with most species were Fabaceae (14), Euphorbiaceae (11) and Lamiaceae (6). The species
with greatest use value (UV) were Myracrodruon urundeuva Allemão (0.65), Dysphania ambrosioides
(L.) Mosyakin and Clemants (0.63) and Amburana cearensis (Allemão) A.C.Sm. (0.42). The leaves were
the parts most frequently used (26.8%), followed by bark (21.0%). Of the 15 used categories listed in this
study, those with the highest number of recorded species were related to illnesses associated with the
digestive tract (102), diseases of the genitourinary system (72) and diseases of the respiratory system
(60). This study revealed the importance of knowledge and use of medicinal plants in caring for the
health of people and domestic animals in the municipality. In addition, the study provided information
on plants of the local flora with pharmacological potential.

The 558 km range extension of the Amazonian aroid Dracontium nivosum (Lem.) G.H.Zhu into semiarid Northeast Brazil is confirmed. This species occurs in Ceará in threatened fragments of brejo forest at ca. 580–870 m elevation. An illustrated taxonomic description is provided. The species’ Extent of Occurrence (EOO) is estimated as 356,392 km2 (meets Least Concern); the Area of Occupancy (AOO), 60 km2 using a 2×2 km cell (Endangered). Within Ceará the EOO is 41.4 km2 (Critically Endangered) and the AOO is 16 km2 (Endangered).
