本文讨论了产于密克罗尼西亚的木菠萝属植物的命名和分类问题，主要涉及木菠萝A. alcohol和A. mariannensis;前者是一广布的通常不育的栽培的种;后者被认为是在马里亚纳群岛的一种天然的森林树和在密克罗尼西亚的其它地方种植。简要描述了这些物种之间的一些变异和间交，这些变异被解释为渐渗的结果。建议的过程中，通过这种方式，涉及不育的父母可以发生基因渗入。人的影响，在运输的父母和后代在岛屿之间的大距离，并在塑造由此产生的人口，进行了讨论。一个更深入的研究，形态学和实验的愿望，强调。我们满意地宣布Barrau博士正在进行这样一项研究。
SummaryA discussion of the nomenclature and taxonomy of the members of the genusArtocarpus found in Micronesia is presented, principally concerningA. altilis andA. mariannensis; the former is a widespread usually sterile cultivated species; the latter is considered a native forest tree in the Marianas Islands and planted elsewhere in Micronesia. Brief descriptions are presented of a number of variants and intergrades between these species, these variants are interpreted as the results of introgression. Processes are suggested, by means of which introgression involving a sterile parent could take place. Man’s influence both in transporting the parents and progeny over large distances between islands and in shaping the resulting populations, is discussed. Desirability of a much more intensive study, both morphological and experimental, is stressed. The fact that such a study is being undertaken by Dr. Barrau is announced with satisfaction.
