摘要

摘要杂交的Polystichum × arendsii最早是由Georg Arends在20世纪初培育的。它是假单胞菌(p.m ulf。)C. Presl，原产于北美西北部，和P. aculeatum (L.)罗斯，发生在欧亚地区。1906年，著名的瑞士植物学家Konrad H. Christ将这种杂交植物命名为Aspidium x arendsii。在接下来的几十年里，蕨类植物消失了，它的名字也被遗忘了。本研究调查了杂交的历史。在此期间，再次成功地进行了杂交，并提供了一种新的P. xarendsii描述。通过对植物标本馆资料的研究和对Konrad H. Christ提供的资料的比较，以及对孢子的分析，证实了该杂交种与原a.x arendsii相对应，并为Polystichum下提供了必要的有效组合。

The Hybrid Fern Polystichum × arendsii

Abstract. The hybrid Polystichum × arendsii was first bred by Georg Arends at the turn of the 20th century. It was an artificial cross between P. munitum (Kaulf.) C. Presl, native to north western North America, and P. aculeatum (L.) Roth, occurring in the Eurasian region. In 1906 the well-known Swiss botanist Konrad H. Christ applied the name Aspidium × arendsii to this hybrid. In the following decades the fern was lost and its name was forgotten. The present study investigates the history of the hybrid. In the interim, the cross has been successfully carried out once again and a new description of P. × arendsii is provided. Study of herbarium material and comparison of the information supplied by Konrad H. Christ, as well as the analysis of the spores, confirmed that the hybrid corresponds with the original A. × arendsii and a necessary valid combination under Polystichum is provided.
