对欧洲西南部和北非地区梨属的多变量形态计量学研究表明，该地区可识别出5种梨属植物：， P. communis L.， P. cordata Desv.；P. spinosa Forssk， P. nivalis Jacq。提出了一些有价值的鉴定特征。果梗宽度、花瓣大小、叶片宽度和叶柄长度是鉴别分类群的重要指标。几个名字，如P. gharbiana Trab。， P. cossonii Rehder (= P. longipes Balansa ex Coss)；& Durieu)和P. boisserana Buhse，被认为是P. cordata的同义词，而P. mamorensis Trab。布氏木属的因此，提供了这些物种的检查清单和钥匙。(C) 1996年伦敦林奈学会
A multivariate morphometric study of the genus Pyrus in south-west Europe and North Africa shows that five species may be recognized in the area: P. bourgaeana Decne., P. communis L., P. cordata Desv., P. spinosa Forssk, and P. nivalis Jacq. Some valuable characters for identification of these species are proposed. In particular the width of fruit peduncle, petal size, leaf width and petiole length serveed to discriminate the taxa. Several names such as P. gharbiana Trab., P. cossonii Rehder (= P. longipes Balansa ex Coss. & Durieu) and P. boisseriana Buhse, are regarded as synonyms of P. cordata, while P. mamorensis Trab. of P. bourgaeana. Consequently a check-list and a key to these species are provided. (C) 1996 The Linnean Society of London
