Paraphlomideae (Lamioideae, Lamiaceae) is a recently established tribe endemic to East and Southeast Asia. It comprises three herbaceous genera: Paraphlomis, Matsumurella, and Ajugoides. Phylogenetic relationships among these genera have not yet been satisfactorily resolved and the monophyly of Paraphlomis was challenged in previous molecular phylogenetic studies. In this study, we performed maximum likelihood and Bayesian inference analyses on complete plastomes and nuclear ribosomal internal and external transcribed spacer sequences to further resolve the generic relationships within Paraphlomideae. All phylogenetic analyses support the monophyly of Paraphlomideae. Contrary to traditional classifications, both Ajugoides and Matsumurella were deeply nested within Paraphlomis, indicating the need to expand Paraphlomis to include Ajugoides and Matsumurella. Hence, six new combinations and one replacement name are proposed. Morphologically, species of the newly defined Paraphlomis share a rhizomatous or stoloniferous habit, plants with simple hairs, nutlets with a truncate apex, and actinomorphic calyces. In addition, widespread incongruence between nuclear and plastid trees may have been caused by hybridization and incomplete lineage sorting after rapid diversification in the re‐circumscribed Paraphlomis.

The typification of the Linnaean name Arum peregrinum, validly published in the first edition of Species plantarum, is discussed. In the absence of original material useful for lectotypification, a study of the various pre‐Linnaean works linked to this name, as well as an in‐depth analysis of literature, was necessary to understand its concept and designate a neotype. Tabula XXXVI in Plumier's Plantarum Americanarum, which was cited by Linnaeus in the tenth edition of Systema naturae under Arum peregrinum, is selected as neotype. Based on the typification, Arum peregrinum is synonymized with Alocasia macrorrhizos.

A phylogenetic study of Uebelmannia investigates the relationships of a newly discovered taxon in this enigmatic, early‐diverging genus that is sister to all the other c. 460 species of tribe Cereeae. Here we present a coalescent‐based phylogenetic tree inferred with nuclear genes captured by the Cactaceae591 probe set encompassing all Uebelmannia species. The new taxon U. nuda is sister to U. pectinifera, while U. gummifera and U. buiningii form another pair of closely related species. The unusual characteristics of the new cactus (semi‐subterranean/geophytic habit, turbinate stem, naked areoles) distinguish it from all other Uebelmannia species. The definition of the relationships within this early‐derived genus endemic to the campo rupestre of Minas Gerais State became more evident, and this new find adds to the importance of this biogeographic province for the evolution of tribe Cereeae. The new species is described, and a preliminary conservation assessment is presented. Additionally, a key for all taxa of the genus is provided.
对 Uebelmannia 的系统发育研究调查了这一神秘、早期分化的属中新发现的一个类群的关系，该类群是 Cereeae 部族所有其他约 460 个物种的姊妹类群。在这里，我们利用仙人掌科 591 探针组捕获的核基因推断出了一棵基于聚合的系统发生树，其中包括所有的 Uebelmannia 物种。新分类群 U. nuda 与 U. pectinifera 是姐妹种，而 U. gummifera 和 U. buiningii 则是另一对亲缘关系很近的物种。新仙人掌的不寻常特征（半地下/地生习性、陀螺状茎、裸窠）将其与所有其他 Uebelmannia 物种区分开来。对这一米纳斯吉拉斯州大裂谷特有的早期衍生属的关系的界定变得更加明显，这一新发现增加了这一生物地理区域对仙人掌科进化的重要性。本文对该新物种进行了描述，并对其保护情况进行了初步评估。此外，还提供了该属所有分类群的检索表。

<jats:italic>Ainsliaea</jats:italic> is an Eastern Asian genus with approximately 50 species, and is characterized by two main habit types or leaf arrangements: rosulate with leaves aggregated at the stem base or pseudo‐verticillate with leaves clustered above the stem base. Most species of <jats:italic>Ainsliaea</jats:italic> have been classified into two sections, <jats:italic>A.</jats:italic> sect. <jats:italic>Ainsliaea</jats:italic> and sect. <jats:italic>Aggregatae</jats:italic>, respectively, based on their habit type. However, recent molecular phylogenetic studies have challenged existing infrageneric classifications for <jats:italic>Ainsliaea</jats:italic>, and the systematic value of habit needs to be re‐evaluated because the habits of some key species were described differently, leading to taxonomic controversies on infrageneric classifications and species delimitations. To address these issues, this study reconstructed a more comprehensive phylogeny of <jats:italic>Ainsliaea</jats:italic> with two more samples of the highly variable <jats:italic>A. lancifolia</jats:italic> and a new sampling of <jats:italic>A. nana</jats:italic>. Habit variations in <jats:italic>Ainsliaea</jats:italic> were observed both in the field and in herbarium collections, and habit evolution was reconsidered based on the updated phylogeny. The phylogenetic analysis highly supports that <jats:italic>A. uniflora</jats:italic> and <jats:italic>A. lancifolia</jats:italic> form the first‐ and the second‐earliest diverging lineages in <jats:italic>Ainsliaea</jats:italic>, respectively; <jats:italic>A. nana</jats:italic>, recently rediscovered by us after more than 60 years, constitutes a distinct lineage sister to a large clade with all leaves aggregated above the stem base; and <jats:italic>A. pertyoides</jats:italic> forms another large clade with the rosulate‐leaf species. The latter three species have distinct habits: <jats:italic>A. lancifolia</jats:italic> with leaves sparsely alternate along the stem but often reduced to a basal rosette in rheophytic environments, <jats:italic>A. nana</jats:italic> with leaves aggregated at and also above the same stem base, and <jats:italic>A. pertyoides</jats:italic> with rosulate leaves when young. Thus, two new sections, <jats:italic>A.</jats:italic> sect. <jats:italic>Alternae</jats:italic> sect. nov. and <jats:italic>A.</jats:italic> sect. <jats:italic>Intermediae</jats:italic> sect. nov., are proposed to accommodate <jats:italic>A. lancifolia</jats:italic> and <jats:italic>A. nana</jats:italic>, respectively, and <jats:italic>A. pertyoides</jats:italic> is reasonably kept in <jats:italic>A.</jats:italic> sect. <jats:italic>Ainsliaea</jats:italic>.

Ainsliaea 是东亚的一个属，约有 50 个种，有两种主要的习性类型或叶片排列方式：莲座状叶片聚生在茎基部，或假圆柱状叶片簇生在茎基部上方。Ainsliaea 的大多数种类被分为两个部分，A. sect.Ainsliaea 和 sect.Aggregatae）。然而，最近的分子系统发育研究对现有的 Ainsliaea 下属分类提出了挑战，由于一些关键种的习性描述不同，导致分类学上对下属分类和种的划分存在争议，因此需要重新评估习性的系统价值。为了解决这些问题，本研究利用两个高度易变的 A. lancifolia 样本和一个新的 A. nana 样本重建了一个更全面的 Ainsliaea 系统发育。在野外和标本馆藏品中都观察到了 Ainsliaea 的习性变异，并根据更新的系统发生重新考虑了习性的演变。系统发生分析高度支持 A. uniflora 和 A. lancifolia 分别是 Ainsliaea 中最早和第二早分化的品系；A. nana 是我们在 60 多年后最近才重新发现的，它是一个独特的品系，隶属于一个所有叶片都聚生在茎基部以上的大支系；A. pertyoides 与莲座叶种组成了另一个大支系。后三个物种有不同的习性：A. lancifolia 的叶片沿茎稀疏互生，但在流变环境中往往退化为基生莲座丛；A. nana 的叶片聚生在同一茎基部和茎基部以上；A. pertyoides 的幼叶为莲座状。因此，有两个新的科，A. sect.Alternae sect.intermediae sect.Ainsliaea。本研究的结果提供了对 Ainsliaea 属习性演化的深入了解，并表明传统的仅以习性为基础的分类方法可能无法准确反映该属的演化历史。新提出的 A. sect.Alternae和sect.新提出的 A. sect.结合系统发育和形态学的证据，本研究提供了该属的谱系以及 A. lancifolia、A. nana 和 A. pertyoides 的分类更新。总之，该研究强调了结合分子和形态学数据来准确分类和了解植物类群进化历史的重要性。
