摘要

摘要我们证明了Tectaria cadieri（Tectariaceae）是越南的一个独特物种，长期以来一直被归为T.ingens的同义词。从形态学上看，卡氏锥虫与金鸡耳虫、刚毛锥虫和毛瘤锥虫相似，它们有大的复叶（长达0.8–2米）、3层固有的薄层、完全游离的静脉和末端节上两排的sori。然而，我们的观察表明，T.cadieri与这些物种的不同之处在于存在线性的膜质托叶鳞片。我们对五个质体区域（atpB、ndhF加ndhF trnN、rbcL、rps16-matK加matK和trnL-trnF）的分析表明，T.cadieri与T.ingens、T.setulosa和T.trichotoma没有密切关系。相反，T.cadieri与T.multicudata有着密切的亲缘关系，后者是一种形态上不同的物种，具有吻合的静脉。除了对T.cadieri的详细描述和插图外，我们还对T.cadier和形态相似物种之间的关系进行了形态学比较和评论。

Resurrection of Tectaria cadieri from T. ingens (Tectariaceae) Based on Morphological and Molecular Data

Abstract We demonstrate that Tectaria cadieri (Tectariaceae) is a distinct species in Vietnam after long being placed under the synonymy of T. ingens. Morphologically, T. cadieri is similar to T. ingens, T. setulosa, and T. trichotoma in their large fronds (up to 0.8–2 m long), 3-pinnate laminae, fully free veins, and sori in two rows on ultimate segments. However, our observations show that T. cadieri differs from these species in the presence of linear, membranaceous stipe scales. Our analyses of five plastid regions (atpB, ndhF plus ndhF-trnN, rbcL, rps16-matK plus matK, and trnL-trnF) show that T. cadieri is not closely related to T. ingens, T. setulosa, nor T. trichotoma. Rather, T. cadieri is closely related to T. multicaudata, a morphologically distinct species with anastomosing veins. Along with a detailed description and illustrations for T. cadieri, we provide morphological comparisons and comments on the relationships between T. cadieri and morphologically similar species.
