摘要

意大利特有的藏红花(Crocusbiflorus)通常开白色或淡紫色的花,花被片外侧有三到五条醒目的紫色纵条纹,但过去也有无条纹植物的记录。这些植物最初被描述为c.a ululatussubvar.estriatus,后来重组为c.a biflorus的一个变种。在托斯卡纳重新发现这些植物使我们有机会澄清它们的系统关系,因此我们对这个名字进行了类型化,并进行了核化学和ITS分析。这些植物具有相同的染色体数(2n = 2x = 8)和ITS序列。

Rediscovery of Crocus biflorus var. estriatus (Iridaceae) and its taxonomic characterisation
The Italian endemic Crocusbiflorus usually shows white or lilac flowers with three-to-five striking violet longitudinal stripes on the outer tepals, but unstriped plants were recorded in the past. These plants were originally described as C.annulatussubvar.estriatus, and subsequently recombined as a variety of C.biflorus. The rediscovery of such plants in Toscana gave us the opportunity to clarify their systematic relationships, so that we typified the name, and performed karyological and ITS analyses. These plants share the same chromosome number (2n = 2x = 8) and ITS sequence with C.biflorus s. str.

期刊介绍: The journal is published on behalf of the Italian Botanical Society (www.societabotanicaitaliana.it). Founded in 1969 as Informatore Botanico Italiano, the journal was initially conceived as a place to publish proceedings of the Society, book reviews etc. During the years, however, the journal acquired scientific contents so that, in 2015, the Italian Botanical Society moved it to the Pensoft platform, with the new name Italian Botanist, in order to disseminate its contents more efficiently. It publishes original research covering all fields of Botany in its wider sense, from molecular to ecosystem levels, including Mycology. The geographical coverage of the journal is specially focused on the Italian territory, but studies from other areas are also welcome. It is a peer-reviewed, open-access, journal.
