摘要
摘要/ Abstract摘要:仙人掌属(Opuntia)是多刺梨仙人掌(nopales)的一个属,约有200种,分类较为复杂。本研究的重点是表征微形态,并提供一个系统发育假说,将Opuntia setocarpa(2017年描述)与其他相关物种进行比较。在墨西哥哈利斯科州Autlán de Navarro市的卡科马山脉Neverías对三个个体进行了特征鉴定和收集。扫描电镜观察了棘、表皮和气孔的显微形态。系统发育假说采用最大似然和贝叶斯推理,包括其他墨西哥物种。麻豆是麻豆属植物中的一种支撑物。
Opuntia setocarpa (Cactaceae, Opuntioideae): Phylogenetic Hypothesis and Notes
Abstract: Opuntia is a genus of plants known as prickly pear cactus (nopales), with about 200 species, and is taxonomically complicated. The present study was focused on characterizing micromorphology and providing a phylogenetic hypothesis to place Opuntia setocarpa (described in 2017) in relation to other related species. Three individuals were characterized and collected in Neverías in the Sierra of Cacoma of the municipality Autlán de Navarro in Jalisco, Mexico. The micromorphology of spines, epidermis and stoma was characterized with scanning electron microscopy. The phylogenetic hypothesis was performed with maximum likelihood and Bayesian Inference including other Mexican species. Opuntia setocarpa is recovered as a supported species within Opuntia s.s.
