分类学远为大的部分是根据形态学的,虽然如此的原因在广义上可稍为历史性的,但它确是不能不如此,为一般方便计鉴定必须尽量容易与快速.自全体说来,分类学家有每一个理由对於自林奈以来用描写与比较形态的方法的成就,感到自豪.无疑的将植物分类为变种,种,属,科与更大的群,曾产生了一种系统,若没有它许多在生态学,细胞学,遗传学,组织学,甚至生理学的近代的发展,将成为不可能.分类学是任何生物学的研究的基础,而没有建议过的任何分类系统可以将为便利计称为甲(alpha),或正统的分类学取而代之,虽为特种的目的而建立的,辅助性的分类的需要是无疑问的.在另一方面,没有分类学家能说现存的系统或其中的任何大部分是完整的或完善的,而且,细胞学,生态学与遗传学的近代发现对于分类学有关系是逐渐变为明显了.在它们之间确有一种有益的相互反映.分类学家必须准备接受它的同僚的建设性的批评而将他们所供给的有关的资料吸收到他的系统中,他 The far more taxonomic part is morphological, though for some reason it may be somewhat historic in its broader sense, but it is indeed true that identification of general conveniences must be as easy and rapid as possible. In all, Taxonomists have every reason to be proud of the achievements made in describing and comparing morphologies since Linnaeus. Undoubtedly, the classification of plants into varieties, species, genera, families, and larger groups has produced a Without its many modern systems of ecology, cytology, genetics, histology, and even physiology, the system would have been impossible. Taxonomy is the foundation of any biological research without any classification system suggested The need for the ancillary classification to be established for special purposes can be replaced by the orthodox taxonomy known as the gage, or on the other hand, no taxonomist can say The existing system, or any part of it, is complete or perfect, and the modern findings of cytology, ecology and genetics have become increasingly apparent for taxonomic purposes. There is indeed a useful Reflect each other. Class scientists must be prepared to accept constructive criticism of its colleagues and the relevant information they supplied absorbed into his system, he
