摘要

在马来西亚沙巴州发现了三个新种：Boesenbergia，B.bosuangii sp.nov.、B.ganaensis sp.nov.和B.gokusingii sp.nov.。Boesenbergiabosuangii与B.stenophylla R.M.Sm.相似，都是狭卵形的薄片，但苞片和花萼的形状不同。Boesenbergiaganaensis 与 B.burttiana R.M.Sm. 关系密切，但在叶舌缺失、叶柄较长、叶基部钝、叶先端锐尖、花萼二裂片和花药通过孔开裂等方面有所不同。最后，B.gokusingii 与 B.variegata R.M.Sm.相似，都是单叶嫩枝，但不同之处在于其叶片不等长，呈卵形，叶基部心形，叶先端锐尖，花药通过气孔开裂。本文对这三个新种进行了详细描述和图解。加上这些新种，沙巴共有 13 个种和一个变种。

Three new species of Boesenbergia (Zingiberaceae) from Sabah, Malaysia.

Three new species of Boesenbergia, B.bosuangii sp. nov., B.ganaensis sp. nov. and B.gokusingii sp. nov. were discovered in Sabah, Malaysia. Boesenbergiabosuangii is similar to B.stenophylla R.M.Sm. in the narrowly ovate lamina but differs in the shape of the bract and the calyx. Boesenbergiaganaensis is closely allied to B.burttiana R.M.Sm. but differs in the absence of a ligule, the longer petiole, the obtuse leaf base, the acute leaf apex, the bilobed calyx and the anther dehiscing by pores. Finally, B.gokusingii is similar to B.variegata R.M.Sm., by the single leafy shoot but differs in having an unequal, ovate lamina, a cordate leaf base, an acute leaf apex and the anther dehiscing by pores. The three new species are described and illustrated in detail. With the addition of these new species, there are in total 13 species with one variety in Sabah.
