摘要

尽管它们在形态上非常相似,但来自波多黎各和伊斯帕尼奥拉岛(多米尼加共和国)的两个独特的山地微型Melocactus种群被视为不同的物种。经过多年对两个岛屿遗址的几种现存植物及其栽培后代的对比,得出的结论是,将它们分开的微小的营养差异不能作为物种识别的理由。因此,最近描述的来自波多黎各Sierra de Cayey陡峭山坡的Melocactus pygmaeus Hoxey, Gdaniec和Ackerman被视为先前描述的来自多米尼加共和国中部山脉Constanza岩石悬崖的Melocactus praerupticola Areces的亚种。同样,根据营养和花的特征,在这种praereticola - pygmaeus复合体和古巴的M. guitartii León之间没有发现明显的相似性。

Melocactus praerupticola Areces subsp. Pygmaeus (Hoxey, Gdaniec et Ackerman) Areces comb. et stat. nov.: Review of the Miniature Mountain Melocactus Populations of the Greater Antilles
Though they are morphologically very similar, the two unique mountain populations of miniature Melocactus from Puerto Rico and Hispaniola (Dominican Republic) have been treated as different species. After contrasting several living plants and their cultivated descendants from both island-sites over the years, it is concluded that the minor vegetative differences that separate them do not justify species recognition. As a result, the recently described Melocactus pygmaeus Hoxey, Gdaniec and Ackerman from the steep slopes of Sierra de Cayey, Puerto Rico is hereby treated as a subspecies of the previously described Melocactus praerupticola Areces from the rocky cliffs of Constanza, in the central mountains of the Dominican Republic. Likewise, based on vegetative and floral characters, no apparent similarities were found between this praerupticola–pygmaeus complex and M. guitartii León from Cuba.
