Abstract

ABSTRACT Faced with ambiguities in a previous typification of Isochilus pauciflorus Cogn., we present a revised typification of this name and comment on its synonyms. Our current study reviews the original materials in open databases of the 23 main herbaria that house orchids from A. Duss, A. Cogniaux or H. G. Reichenbach. Among specimens filed as types, a lectotype (BR0000013217891) is recognized and a presumed isotype (NY00059032) is rejected. However, the lectotype material is not sufficient for precise application of the name. Thus, we designate an epitype based on the specimen K000079638 which refers to the heterotypic synonym Ponera punctulata Rchb. f. to support the name I. pauciflorus. Furthermore, the holotype of P. punctulata commonly accepted and used in the literature is said to be in the Reichenbach Orchid Herbarium, at the Natural History Museum in Vienna (Austria). Unfortunately, this unique gathering is no longer extant or is missing there, but a photograph is available. From this picture, we show that this specimen was not original material, so it was not the holotype. We therefore designate a neotype of P. punctulata Rchb. f. supported by the specimen K000079638. In addition, we designate an epitype of Tetragamestus isochiloides Regel (LE00011188), heterotypic synonym of these above taxa. Finally, the type of Hexadesmia dunstervillei Garay, AMES00287200, is demonstrated to be a lectotype, not a holotype.

标题少花等香的订正类型。(兰科，兰科)及其同义词

摘要:在以往的少花等香属分类中存在歧义。，我们提出了这个名字的修订类型和评论其同义词。我们目前的研究回顾了23个主要植物标本的开放数据库中的原始资料，这些植物标本来自A. Duss, A. Cogniaux或H. G. Reichenbach。在作为类型提交的标本中，识别了一个lectotype (BR0000013217891)，拒绝了一个假定的同型(NY00059032)。然而，原型材料不足以精确应用该名称。因此，我们在标本K000079638的基础上指定了一个表型，该表型指的是异型同义Ponera punctulata Rchb。1 . pauciflorus;此外，文献中普遍接受和使用的马斑兰的完整模式据说在维也纳(奥地利)自然历史博物馆的赖兴巴赫兰花标本馆。不幸的是，这个独特的聚会已经不存在了，或者在那里失踪了，但是有一张照片可以找到。从这张图片中，我们可以看出这个标本不是原始材料，所以它不是原型。因此，我们指定了一种新种。f.由试件K000079638支撑。此外，我们还指定了一个异chiloides Regel (LE00011188)的表型，它是上述分类群的异型同义物。最后，证明了Hexadesmia dunstervillei Garay的类型，AMES00287200是一个集合型，而不是一个完整型。
