Abstract

The present study on Anacardiaceae aims to contribute with the broader survey project of the Phanerogamic flora of the São Paulo state which. This great efford has been supported by FAPESP since 1993 and counts on the collaboration of researchers from many universities and institutes of the state. The family comprises ca. 81 genera and 800 species distributed mostly in lowlands, from dry to moist habitats, throughout the tropics and subtropics worldwide and also extending into the temperate zone. Iin Brazil Anacardiaceae is represented by 14 genera and 57 species. The present survey was carried out based on field work, bibliographical references on Anacardiaceae and examination of the collections from the following herbaria: BHCB, BOTU, ESA, HRCB, MBM, IAC, PMSP, R, RB, SP, SPF, SPFR, SPSF, UEC. The results are presented following the Phanerogamic flora of Sao Paulo State. We provide identification keys to genera and species, morphological descriptions, illustrations and additional data on distribution, habitat, intraespecific variability, periods of flowering and fruiting, species conservation status. In the area this family is represented by 12 native species belonging Anacardium, Astronium, Lithrea, Myracrodruon, Schinus, Spondias e Tapirira. Lithrea molleoides, Schinus terebinthifolius and Tapirira guianensis are the most common and widespread Anacardiaceae species of São Paulo state and they are collected in almost all types of vegetation, including disturbed areas. Spondias mombin occurs in Sazonal Semidecidous and Riparian Forests next to the Paraná River in the northwest and the west regions of the state. S. engleri is reported for São Paulo state in the High-Montane Mixed Ombrophylous Forest of Campos do Jordão and Serra da Bocaina and S. weinmannifolius is found in the \"cerrado\" and \"campos\" of Itararé, Itapeva and other cities located next to the south and the south-west regions of the state. Anacardium is represented in the state by two species, A. humile, a \"cerrado\" common plant with geoxylic habit, and A. occidentale, a \"restinga\" small tree. Astronium graveolens and Myracrodruon urundeuva, as well as the majority of Anacardiaceae species are collected in Sazonal Semidecidous Forests and \"cerrados\" of São Paulo state. An uncommon distribution pattern is found in Lithrea brasiliensis, which is reported for São Paulo state only from type-material. In relation to the species conservation status, Lithrea brasiliensis should be categorized as Presumably Extinct (EX) and Myracrodruon urundeuva as Near Threatened (NT). The other species are classified as Least Concern (LC) category (AU)
