摘要
大果子(CotoneasterconspicuusMesel)是子属(Cotoneaster)中观赏价值尤为显著的种类。自本世纪30年代发表以来,基于这一分布于中国-喜马拉雅地区,形态在该无融合生殖属中相对稳定的类群出现了1个系(SeriesConspicuiKlotz)、5个种7个名称(其中3个为同种加词但根据不同模式即CconspicuusComber;CconspicuusMarquand;CconspicuusMarquandexKlotz;CdecorahortexRehd;Cnanus(Klotz)Klotz;CpermutatusKlotz;CpluriflorusKlotz)和3个变种(CmicrophylusvarconspicuusMesel;CconspicuusvarnanusKlotz;CconspicuusvardecoraRusel)的名称,实为Cotoneaster中因种的划分过细而导致混乱的一个典型。本文在对中国科学院昆明植物研究所和中科院植物研究所标本馆馆藏大果子标本33号共63份、有关名称的模式7号共9份和大量栽培植物的观察研究基础上?
Cotoneaster conspicuus Messel is an ornamental plant with outstanding value for decoration. Based on the species which is distributed in China to Himalayan and with comparable stable characters in the apomictic genus, names of one series(Series Conspicui Klotz),5 species with 7 specific epithets( C conspicuus Messel; C conspicuus Comber; C conspicuus Marquand; C conspicuus Marquand ex Klotz; C decora hort ex Rehd; C nanus (Klotz)Klotz; C permutatus Klotz; C pluriflorus (Klotz)and three names of varieties( C microphyllus var conspicuus Messel; C conspicuus var decora Russell; C conspicuus var nanus Klotz)have been validly published since establishment in 1930′s. This is a typical example with nominal confusion because of using over loaded detail characters in taxonomic treatment of the apomict population. On the basis of specimen observations of 33 numbers and 63 duplicates which are preserved in PE and KUN,7 numbers and 9 duplicates of type specimens which are loaned from BM,K & A,and observation of mang living plants cultivated while considering the cytological evidence,a taxonomic revision of this species was carried out All above names were reduced as synonyms of Cotoneaster conspicuus Messel as a result
