This report describes Thismia belumensis Siti-Munirah & Suhaimi-Miloko, a novel species of achlorophyllous herb discovered in the Royal Belum State Park, Peninsular Malaysia. This new species is unlike any previously described species of Thismia. In particular, T. belumensis possesses a unique annulus, which has been expanded and modified into a cucullate (hood-like) structure. This structure covers the apical floral tube and has an opening on one side facing a thickened part of the annulus, and the off-centre floral aperture confers a zygomorphic symmetry to the flower, indicating T. belumensis is more similar to Thismia labiata J.J.Sm. This morphological detail makes this new species distinct from all other described species of Thismia. In this report, we provide descriptions, illustrations, colour plates, and the provisional conservation status of Thismia belumensis.

藜（Thismiaceae），来自马来西亚半岛霹雳州Gerik的皇家贝鲁姆州立公园的引人注目的新物种

这份报告描述了在马来西亚半岛皇家贝卢姆州立公园发现的一种新的叶绿素草本植物，这是一种叫做西米亚白花iti Siti-Munirah和Suhaimi-Miloko的植物。这个新物种不同于提斯米亚的任何先前描述的物种。特别地，白僵菌具有独特的环，该环已被扩展​​并修饰成小节状（罩状）结构。这种结构覆盖了顶端花管，并且在面向环的加厚部分的一侧上有一个开口，偏心的花孔使花具有flower形对称性，这表明beamensis T. belumensis与Thismia labiata JJSm更相似。这种形态学的细节使这种新物种与提斯米亚的所有其他其他物种截然不同。在此报告中，我们提供了说明，插图，色板，
