摘要

对巴西大西洋森林生物多样性热点地区的新物种Ouratea yamamotoana（Ochnacee）进行了描述和说明。这个新物种类似于Ouratea camposportoi，与之不同的是，它有宿存的托叶、基部心形或略耳形的黄褐色叶子、较小的花梗、匙形或椭圆形花瓣、较长的雌核柄和具有近圆柱状到棒状车柄的果实。根据国际自然保护联盟红色名录标准，它被评估为易危（VU），并强调了对大西洋森林高度特有植物多样性的威胁。

OURATEA YAMAMOTOANA (OCHNACEAE), A NEW SPECIES FROM THE BRAZILIAN ATLANTIC FOREST

The new species Ouratea yamamotoana (Ochnaceae) from the Brazilian Atlantic Forest biodiversity hotspot is described and illustrated. The new species resembles Ouratea camposportoi, from which it differs by the persistent stipules, chartaceous leaves with cordate or slightly auriculate base, flowers with smaller pedicels, spathulate or elliptic petals, longer gynophore, and fruit with a subterete to clavate carpophore. It is assessed as Vulnerable (VU) using IUCN Red List criteria and highlights the threats to the highly endemic plant diversity of the Atlantic Forest.
