摘要

Halda&Panarotto星藻的茎形态与肉豆蔻星藻亚种的异常生长形式一致。图伦塞是在文化中发现的。A.mirum的花与亚种的花无法区分。图伦塞。A.mirum的模式位置，现在仅限于塔毛利帕斯州的Mamaleón，位于亚种的栖息地。图伦塞。两个分类群之间种子大小和根系形态的差异没有得到证实，因为没有用该类型材料保存任何实例。结果表明，小星藻Halda&Panarotto是肉豆蔻星藻亚种的初级异名。图伦斯·凯泽。

Taxonomic status of Astrophytum mirum (Cactaceae)

Astrophytum mirum Halda & Panarotto has a stem morphology that agrees with that of an anomalous growth form of Astrophytum myriostigma subsp. tulense discovered in culture. The flower of A. mirum is indistinguishable from the flower of subsp. tulense. The type locality of A. mirum, now restricted to Mamaleón, Tamaulipas, is situated in the habitat of subsp. tulense. Alleged differences in seed size and root morphology between the two taxa are not confirmed as no examples were preserved with the type material. The conclusion is drawn that Astrophytum mirum Halda & Panarotto is a junior synonym of Astrophytum myriostigma subsp. tulense Kayser.

期刊介绍： The Journal of the Botanical Research Institute of Texas, formerly called Sida, Contributions to Botany, publishes research in classical and modern systematic botany—including studies of anatomy, biogeography, chemotaxonomy, ecology, evolution, floristics, genetics, paleobotany, palynology, and phylogenetic systematics. Geographic coverage is global. Articles are published in either English or Spanish; an abstract is provided in both languages. All contributions are peer reviewed and frequently illustrated with maps, line drawings, and full color photographs.
