摘要

Freziera Willd属。分布在委内瑞拉的主要山脉系统，包括洛斯安第斯山脉、海岸科迪勒拉山脉和瓜亚纳地盾。委内瑞拉已知的11种Freziera物种中有2种是该国特有物种，可能处于濒危状态，但根据国际自然保护联盟的标准，它们的实际保护状况尚不清楚，数据不足。在这项工作中，首次提供了委内瑞拉物种的钥匙，并对来自梅里达科迪勒拉的Freziera polita a.L.Weitzman ex J.R.Grande，sp.nov.进行了描述和说明。该新种的诊断特征与F.Guaramacalana D.Santam.&Cuello最为相似，包括细长的叶柄、近无毛的成熟叶和不到萼片一半长度的花冠（开花时）。

Sertulum Ternstroemiacearum I. Sinopsis del género Freziera (Ternstroemiaceae) en Venezuela, incluyendo una especie nueva de la Cordillera de Mérida

The genus Freziera Willd. is distributed in Venezuela along major mountain systems, including Los Andes, Coastal Cordillera, and Guayana Shield. Two out of 11 Freziera species known from Venezuela are endemic to this country and could be endangered, but their actual conservation status is unknown, being Data Deficient according to the criteria of the IUCN. In this work, a key for the Venezuelan species is provided for the first time, and Freziera polita A.L.Weitzman ex J.R. Grande, sp. nov., from Cordillera de Mérida, is described and illustrated. Diagnostic characters of the new species, which is most closely similar to F. Guaramacalana D.Santam. & Cuello, include elongated petioles, subglabrous mature leaves, and corollas (at anthesis) that are exerted less than half the length of sepals.
