Abstract

Recent studies on Canthium revealed that the genus is polyphyletic. Subsequently, Canthium sensu stricto ( s.s. ) was re-delimited to species having paired supra-axillary spines, which led to the reinstatement of various genera in the Vanguerieae such as Keetia, Psydrax and Pyrostria . This raised questions on the generic affiliations of Philippine Canthium species as most of its members lacked spines. In an effort to revise the Philippine Canthium , the endemic spineless Canthium subsessilifolium was collected to ascertain its generic affiliation within the tribe using plastid ( trnL-F region) and nuclear (ITS region) markers. The majority-rule consensus tree of combined data sets showed a wellsupported clade of the whole Vanguerieae (PP=1.00). Interestingly, C. subsessilifolium was nested within the robustly supported Pyrostria clade (PP=1.00). Morphological similarities of C. subsessilifolium with Pyrostria further supported our molecular results. Therefore, a new combination is here provided: Pyrostria subsessilifolia (Merr.) Arriola & Alejandro. This study establishes for the first time the existence of Pyrostria in the Philippines. Keywords : Canthium; ITS; Pyrostria; Rubiaceae; trnL-F; Vanguerieae

从分子和形态资料推断菲律宾火蝇属新记录

最近的研究表明，该属是多系的。随后，Canthium sensu stricto (s.s。)被重新划分为具有配对腋窝上棘的种，这导致了先锋科中各种属的恢复，如Keetia, Psydrax和Pyrostria。这引起了对菲律宾Canthium物种的归属问题，因为它的大多数成员缺乏刺。为了修订菲律宾Canthium，我们收集了菲律宾特有的无棘Canthium subsessilifolium，利用叶绿体(trnL-F区)和核(its区)标记确定其在部落中的属属关系。组合数据集的多数规则共识树显示整个前卫的分支得到了很好的支持(PP=1.00)。有趣的是，C. subsessilifolium被嵌套在坚固支撑的火虫枝中(PP=1.00)。在形态学上与火孢菌的相似性进一步支持了我们的分子结果。因此，这里提供了一个新的组合:亚sessilifolia (Merr。Arriola & Alejandro。本研究首次证实菲律宾有火虫。关键词:蛇皮;它的;Pyrostria;茜草科;trnL-F;Vanguerieae

期刊介绍： The Philippine Journal of Systematic Biology (Print ISSN: 1908-6865; Online ISSN: 2508-0342) is an annual, peer-reviewed journal in English that publishes high quality reports of original research and reviews in the field of Taxonomy & Systematics, Ecology and Conservation Biology. The PJSB is a CHED recognized journal under CHED CMO 50 series of 2017. It is also included in the Clavariate Analysis (formerly a subsidiary of Thomson Reuters) Master Journal List under Zoological Record, BIOSIS Previews and Biological Abstracts.The PJSB is the official publication of the Association of Systematic Biologists of the Philippines (SEC Registration: Association of Philippine Taxonomists, Inc.). The organization financially supports the journal and all its endeavors. The journal aims to build up quality information on animal, plant and microbial diversity in the Philippines. Articles dealing with original research or reviews in Zoological, Botanical or Microbial Systematics, Ecology and Conservation Biology are welcome. Authors are advised to consult a recent issue of PJSB for the current format and style. All manuscripts are reviewed by at least two qualified referees.
