A new genus, , for the Brodiaeoideae, Asparagaceae family is here proposed. A taxonomic analysis based on morphology highlights its synapomorphies. The characters that distinguish are the absence of a pith in the gynophore and the presence of an entire stigma. The recognition of as a monotypic genus is supported by the development of a short floral tube (< 2 mm) and a pith in the gynophore, as well as a divided stigma shared with the other genera of the clade, , , and . A key to its taxonomic determination is given for both the species and the clade genera.
本文提出了天门冬科布罗迪亚花亚科的一个新属。基于形态学的分类分析突出了其共衍征。区分该新属的特征是雌蕊柄中无髓以及柱头完整。该新属作为单型属的认定得到了以下特征的支持:短花管(<2毫米)的发育、雌蕊柄中有髓,以及与该分支的其他属(、、和)共有的分裂柱头。给出了该新属物种和该分支各属分类鉴定的检索表。
