Abstract

ABSTRACT. Molecular analyses and cytological data have shown that Silene multinervia, which has always been placed in section Conoimorpha and often regarded as a heterotypic synonym of S. coniflora, is a separate taxon in a distinct clade. A comparison between S. multinervia and the members of section Conoimorpha is provided, showing that the species can be distinguished by both vegetative (plant height) and reproductive (flower number per inflorescence, calyx vein number, calyx length, petal apex shape, fruit length, carpophore length, and seed diameter) characters. Cytological, molecular, and morphological evidence support recognition of S. multinervia as a member of a new section endemic to southwestern California and northwestern Mexico (Baja California). Therefore, Silene sect. Californicae, sect. nov. (type: S. multinervia) is here proposed.

加利福尼亚和墨西哥西北部特有的石竹科多叶石竹的分类地位及加利福尼亚科11 . 11 .的描述。
摘要分子分析和细胞学资料表明,多叶蝉(Silene multinervia)是一个独立的分类单元,它一直被置于Conoimorpha组中,通常被认为是coniflora的异型同义种。通过与Conoimorpha组成员的比较,表明该物种可以通过营养性状(株高)和生殖性状(每花序花数、萼脉数、萼长、瓣尖形状、果实长度、果柄长度和种子直径)进行区分。细胞学、分子学和形态学证据支持多叶菊作为加利福尼亚西南部和墨西哥西北部(下加利福尼亚)特有的一个新分支的成员。因此,这里提出了加利福尼亚科沉默节,第11节(类型:多叶蝉)。
