摘要

在Nueva Ecija的Pantabangan–Carranglan流域森林保护区内，遇到了一小群不起眼的秋海棠。经深入调查，本属菲律宾秋海棠新种。彼得曼尼亚。新品种秋海棠（Begonia naemma Y.P.A.ng，Aumentado&Magtoto）与同源品种B.polycada C.I Peng，C.W.Lin&Rubite的区别在于其较大的叶片，叶脉之间的叶片正面稀疏多毛，更多的雄蕊，以及卵形到长圆形的较大的卵巢翅膀。根据国际自然保护联盟的标准，秋海棠被指定为濒危物种（EN）。对秋海棠痣进行了全面的描述和说明。

BEGONIA NAEMMA (SECT. PETERMANNIA, BEGONIACEAE), A NEW SPECIES FROM NUEVA ECIJA, LUZON ISLAND, THE PHILIPPINES

Within the Pantabangan–Carranglan Watershed Forest Reserve in Nueva Ecija, a small population of an inconspicuous Begonia was encountered. After thorough investigation, it is described here as a new Philippine Begonia species in sect. Petermannia. The new species, Begonia naemma Y.P.Ang, Aumentado & Magtoto, is distinguished from the allied species B. polyclada C.I Peng, C.W.Lin & Rubite by its larger leaves, leaf adaxially sparsely hirsute between the veins, more numerous stamens, and larger ovary wings that are ovate to oblong. Based on IUCN criteria, Begonia naemma is designated as Endangered (EN). A comprehensive description and illustration of Begonia naemma are provided.
