介绍。这篇论文是我试图对大自然目百合花的属和种进行专题研究的系列论文的第六篇。正如在之前的一篇论文中所解释的那样，它最自然地分为三个主要的部门或亚目：- 1。丁香梗直立，以一室杀蒴果，一不分开的花柱和内向的花药为标志；第二。圆锥花序，以一具毒囊，三分花柱和外花药为特征；和3日。芦笋属植物，其特点是其果实呈新月形。在这些目之外，还有三个异类，科南科、利里科和利里科，那些倾向于把自然目的数目相乘的人，可能会认为它们是不同的目。在我的论文一篇接一篇的轮换中，我遵循的是工作上的方便，而不是建立在亲和力基础上的严格的植物顺序。本论文包括整个秋水仙科和刚刚命名的三个异常部落的属和种，此外，还有三个小部落的百合科，它们几乎是澳大利亚所特有的，我现在只讨论它们，以便在将来的时候只讨论两个明确的群体：第一种是苏卡百合科（丝兰和DasyZirion与芦荟）；其次是Allieae部落，除了它的大模式属外，它只包括Goyea和Nothoseordzcin。秋水仙科包括39属153种。在百合亚目的三个亚目中，它所包含的偏离其从属特征的属的数量要多得多。在许多属中，花药的脱落绝不是绝对明显的。在包括最多属的秋chicacese部落Uvulariese中，花柱或多或少是结合在一起的。在Anguillarieae， Helonies， Tofieldiere和uvularieae的一些属中，蒴果开裂是杀室性的。39个属中有24个或多或少偏离了理想的秋水仙型方向；因此，想要像人们经常提出的那样，把柯希奇和梅兰提斯作为一种独特的自然秩序来维持下去，似乎是完全没有希望的。在这里被收养的七个部落中，Colchicez~， Merenderes和Veratres是仅有的三个
Introduction.-The present paper is the sixth of a series in which I have attempted to monograph the genera and species of the great natural order Liliaces. AS has been explained in a previous paper, it is most naturally separated into three main divisions or suborders:-lst. Lilincece vere, marked by a loculicidal capsule, an undivided style, and introrse anthers; 2nd. Cobhicacece, marked by a septicidal capsule, a tripartite style, and extrorse anthers; and 3rd. Asparagacete, characterized by its baccate fruit. Outside these stand three aberrant tribes, Conanthereae, Liriopeae, and Gilliesies, which those who are inclined to multiply the number of natural orders might plausibly regard as distinct orders. In the rotatiou in which my papers have succeeded one another, I have followed working convenience, and not strict botanical sequence founded upon affinity. The present paper includes the whole of Colchicaceae and the genera and species of the three aberraut tribes just named, and, in addition, three small tribes of Liliacea Vera which are almost peculiar to Australia, and which I treat now so as to leave only two well-marked groups to be dealt with on a future occasion:-firs $ the suffruticose Liliacem (Yucca and DasyZirion with the Aloines); and, secondly, the tribe Allieae, which only includes Goyea and Nothoseordzcin in addition to its large type genus.The suborder Colchicaceae includes 39 genera and 153 species. Of the three suborders of Liliaces, it includes by far the greater number of genera which deviate from the subordinal characteris tics. In a large number of the genera the dehiseence of the anther is by no means definitely extrorse. In Uvulariese, the tribe of Colchicacese which includes the largest number of genera, the styles are more or less combined. In Anguillarieae, Helonies, Tofieldiere, and some of the genera of Uvularieoe the dehiscence of the capsule is loculicidal. Altogether 24 out of 39 genera deviate more or less from the ideal Colchicaceous type in the direction of Liliacese verae; so that it seems utterly hopeless to attempt to keep up Colchicaces or Melanthiaces as a distinct natural order, as has often beeu proposed. Out of the seven tribes here adopted, Colchicez~, Merenderes, and Veratres are the only three
