摘要

摘要:第一个发现hahnianus的人是Harry Blossfeld。根据文献分析，T. Rojas和A.M. Friedrich似乎在20世纪30年代中期发现了这一发现，然后将种子或插枝交给了Marsoner，并最终通过H. Blossfeld到达了R. Blossfeld的苗圃。虽然哈恩在欧洲种植了这种植物，但目前人们只知道它是1937年在美国由j·韦斯特(J. West)从罗哈斯(Rojas)那里克隆出来的。最近，发现了一个新的群体，它似乎是一个克隆体。从形态、花朵、生长习性、染色体数目、种子形态等方面来看，与美国无性系完全吻合，但两地相距400公里。讨论了分类学和命名法:我们决定保留该物种在毛虫属中，使用基于形态特征的保守概念。这里指定了一种中庸的新类型。

Mediocactus hahnianus: A Resolved Enigma and a New Chapter of Its History

Abstract: The first discovery of Mediocactus hahnianus was attributed to Harry Blossfeld. Based on literature analysis, it is shown that T. Rojas and A.M. Friedrich plausibly made the discovery in the mid-1930s, and that seeds or cuttings were then given to Marsoner and eventually arrived at R. Blossfeld's nursery via H. Blossfeld. Although cultivated in Europe by Hahn, the plant is presently known only from the clone grown by J. West in the US, and obtained from Rojas in 1937. Recently, a new colony has been found and it seems to be a single clone. It perfectly fits the US clone from the point of view of morphology, flowers, growth habit, chromosome number, and seed morphology, whereas the localities are 400 km away from each other. Taxonomy and nomenclature are discussed: We decided to retain the species in Trichocereus, using a conservative concept for the genus based on morphological characters. A neotype for Mediocactus hahnianus is designated here.
