    摘要

    辐冠苣苔属为中国广东特有苦苣苔科单型属，因其具有苦苣苔科中相对比较少见的辐射状花冠裂片而得名。有学者提出因其属名Actinostephanus F. Wen, Y. G. Wei & L. F. Fu和已灭绝的化石浮游植物属名Actinostephanos Khursevich极其相似而易于混淆，应处理为晚出同名。依据2018年《国际藻类、菌物和植物命名法规 (深圳法规)》，该文为该晚出同名拟定了一个新名称，即Radiaticorollarus Y. G. Wei, F. Wen & Lei Cai，并将其属下辐冠苣苔Actinostephanus enpingensis F. Wen, Y. G. Wei & Z. B. Xin处理为新组合Radiaticorollarus enpingensis (F. Wen, Y. G. Wei & Z. B. Xin) F. Wen, Y. G. Wei & Lei Cai的异名。

    Abstract

    Actinostephanus F. Wen, Y. G. Wei & L. F. Fu is a monotypic genus in Gesneriaceae endemic to Guangdong, China. It is named for its radiate corolla lobes, the relatively rare character among Gesneriaceae. Some scholars have suggested that the name Actinostephanus is easily confused with the generic name of the extinct fossil phytoplankton Actinostephanos Khursevich, and proposed that Actinostephanus should be treated as a later homonym of Actinostephanos. According to the International Code of Nomenclature of Algae, Fungi and Plants (Shenzhen Code) (2018), we here propose a new name Radiaticorollarus Y. G. Wei, F. Wen & Lei Cai for the later homonym Actinostephanus F. Wen, Y. G. Wei & L. F. Fu, and treat Actinostephanus enpingensis F. Wen, Y. G. Wei & Z. B. Xin as a synonym of the new combination Radiaticorollarus enpingensis (F. Wen, Y. G. Wei & Z. B. Xin) F. Wen, Y. G. Wei & Lei Cai.

  • The genus Actinostephanus F. Wen, Y. G. Wei &L. F.Fu was named for its radiate corolla lobes, the relatively rare character among Gesneriaceae. It includes a single species, A. enpingensis F. Wen, Y. G. Wei &Z.B.Xin. The genus name, “Actinostephanus”, is derived from Greek, with the prefix “Actino-” coming from ἀκτi-'ζ（Akti-'s, meaning “ray” or “radiate”) and “stephanus” from Στέφαvoς (Stéphanos, meaning “crown”) . This type of corolla characteristic is rare in Chinese Gesneriaceae. Before the discovery of this new genus, only three species, belonging to two different genera, have radially spreading corollas: Bournea sinensis Oliv., B. leiophylla (W. T. Wang) W. T. Wang &K.Y.Pan ex W.T.Wang, and Oreocharis esquirolii H. Lév.

  • However, Khursevich (1989) had named a kind of extinct fossil phytoplankton Actinostephanos Khursevich (1989: 487) using a homological name. Despite the difference of a single letter between the two names, “u” and “o”, which is sufficient to differentiate them, Deshmukh (2022: 1127) believed they are extremely similar and prone to confusion and should be treated as homonyms, thus requesting a binding decision that the names Actinostephanus Wen et al. and Actinostephanos Khursevich are easily confused and should be treated as homonyms. This request was recommended by The Nomenclature Committee for Algae (Anderson, 2023) and approved by General Committee.

  • Therefore, according to Article53.1 of the Interna-tional Code of Nomenclature for algae, fungi, and plants (Shenzhen Code) (Turland et al., 2018) , a new name, Radiaticorollarus Y.G.Wei, F.Wen &Lei Cai, is pro-posed herein for the later homonym Actinostephanus F. Wen, Y. G. Wei &L. F. Fu. Radiaticorollarus is com-posed of two Latin words, “Radiati-” deriving from “Radiatus”, meaning radiate, and “corollarus” from “corolla”, meaning corolla. This replacement name retains the same meaning as the original Actinostephanus, referring to the unique species in this genus known to have a campanulate corolla tube and radially symmetrical corolla lobes, distinct from all other known genera in China.
