A new genus from Borneo, Y.Y.Sam, is described here. The genus currently contains eight species previously classified as members of the Baker. The finding is based on the results of the morphological and molecular studies of throughout its geographical range and its closely allied sister groups, M.F.Newman and A.Takano & Nagam. is nested within the tribe Zingibereae and its monophyly is strongly supported by both ITS and matK sequence data. The genus is characterised by several thin, translucent and marcescent floral bracts, absence of coloured streaks on the labellum and capitate stigma with two dorsal knobs. The genus is distributed in northwest Borneo and all species are very rare and highly endemic.
这里描述了一个来自婆罗洲的新属，Y.Y. 萨姆。该属目前包含八个先前被归类为贝克属成员的物种。这一发现基于对其整个地理分布范围及其近缘姐妹群进行形态学和分子研究的结果，作者为M.F. 纽曼以及A. 高野和永深。该属嵌套在姜族中，其单系性得到ITS和matK序列数据的有力支持。该属的特征是有几片薄的、半透明且会枯萎的花芽苞片，唇瓣上没有彩色条纹，以及具两个背侧瘤的头状柱头。该属分布于婆罗洲西北部，所有物种都非常稀有且高度特有。
