Begonia is a mega-diverse genus of flowering plants prone to generating micro-endemic species, especially on limestone habitats. During fieldwork in the Puerto Princesa Subterranean River National Park, Palawan (Philippines), three species were encountered which did not match any previously described from the region.
Following morphological, anatomical, molecular phylogenetic and cytological investigation a hypothesis of three new species is supported. The three new species belong to a clade endemic to Palawan and Borneo.
The limestone habitats in the Puerto Princesa Subterranean River National Park environs support a unique flora. The description of three new species from a small area within the park demonstrates how much remains to be discovered there, and the importance of its continued protection.
秋海棠属是一个种类繁多的开花植物属,容易产生微特有种,尤其是在石灰岩生境中。在菲律宾巴拉望公主港地下河国家公园的野外工作期间,发现了三个与该地区先前描述的任何物种都不匹配的物种。
经过形态学、解剖学、分子系统发育和细胞学研究,支持了三个新物种的假说。这三个新物种属于巴拉望和婆罗洲特有的一个分支。
公主港地下河国家公园周边的石灰岩生境支持着独特的植物群落。从公园内一个小区域描述的三个新物种表明,那里仍有许多有待发现的地方,以及持续保护该地区的重要性。
