A lectotype is designated for the name of the iconic and well‐known macrolichen Ramalina menziesii Taylor from among a suite of largely overlooked syntypes deposited in the Thomas Taylor Herbarium at the Farlow Herbarium, Harvard University. Lectotypes are also selected for the synonyms of R. menziesii: Chlorodictyon foliosum, Ramalina reticulata (≡ Lichen reticulatus Noehd., nom. illeg.) and R. retiformis. The place of publication of L. reticulatus Noehd. is discussed in detail. The case highlights the surprising degree to which the application of names for taxa that have been extensively studied and are widely known outside a narrow specialist field, can remain unresolved.
从存放在哈佛大学法洛标本馆托马斯-泰勒标本馆（Thomas Taylor Herbarium）的大量被忽视的同种异名中，为标志性的著名大丽花Ramalina menziesii泰勒指定了一个讲座模式。menziesii 的异名中也选取了分型：Chlorodictyon foliosum、Ramalina reticulata (≡ Lichen reticulatus Noehd., nom. illeg.) 和 R. retiformis。L. reticulatus Noehd.的发表地点进行了详细讨论。该案例突出表明，对于那些已经被广泛研究并在狭窄的专业领域之外广为人知的分类群，其名称的应用在令人惊讶的程度上仍然是悬而未决的。

Commonly considered bispecific, Acorus is one of the most phylogenetically isolated angiosperm genera that forms the order Acorales sister to the rest of the monocots. The Acorus calamus group is widely distributed in the Holarctic regions of Eurasia and America and has strong medicinal and other practical uses since prehistoric times. Earlier studies interpreted native diploids and invasive triploids occurring in North America as two species that differed in morphology and distribution ranges. In contrast, diploids, triploids, and tetraploids occurring in Eurasia are commonly interpreted as one species because they reportedly cannot be distinguished in collections. We resolve the controversy over taxonomic concepts between Eurasia and America and provide the first detailed multidisciplinary account of Acorus in temperate Asia. We used plastid and nuclear markers, leaf anatomy, seed micromorphology, pollen stainability, flow cytometry, and direct chromosome counts. Diploids and tetraploids show stable molecular and micromorphological differences. Triploids are their sterile hybrids, with the plastid genome inherited from the diploid parent. Diploids of America and Asia tend to differ in leaf characters. Coadaptative coexistence with pollinating beetles Platamartus jakowlewi and Sibirhelus corpulentus (Kateretidae) is conserved between diploids and tetraploids and over a distance of 4700 km between Japan and Western Siberia. Diploids are self‐compatible and can set seeds in the absence of kateretid beetles. Tetraploids are self‐incompatible and/or cannot set seeds in the absence of Platamartus and Sibirhelus. Diploids (A. americanus) and tetraploids (A. verus) are two biological species; the former has two subspecies. Acorus calamus should be restricted to triploids; it apparently first evolved in temperate Asia. Diploids mostly occur in much cooler climates than triploids and tetraploids. Accessions of A. verus and A. calamus from tropical Asia are apparently derived from ancient introductions. Our data provide a new framework for the pharmacological use of Acorus.

Mountains form a diverse mosaic of microhabitats over small distances created by changes in climate, soil, and water availability. A key to adaptation of plants to such microhabitats is genetic variation; however, natural accumulation of genetic variation through mutation is slow and often not sufficient alone. Adaptive introgression via hybridization is an alternative to generate genetic variation. Here, we investigate hybridization and discuss its adaptive role in Veronica subg. Pseudolysimachium at their Altai Mountains distribution. To support our hypotheses of frequent hybridization, we genotyped thousands of SNPs for 233 individuals from 10 species and 7 putative hybrids previously described based on morphology. We employed Bayesian and likelihood statistical models and supported our results by morphometric analysis and genomic in situ hybridization (GISH). The results suggest that almost all the individuals of the putative hybrids are of F1 type. The GISH investigation in one case strongly supports homoploid hybridization (origin of V. ×schmakovii from V. longifolia and V. porphyriana. Divergence times of Altai Veronica species are estimated to be within 1–2 million years ago with high probability of gene flow over that time. Our results also demonstrate that the direction of gene flow is mainly from the locally endemic V. porphyriana. We hypothesize that the large Siberian plains and topographically diverse foreland of the Altai Mountains provide an ideal setting for hybridization with the potential for adaptive introgression of alleles conferring tolerance to cooler climates, to the lowland species migrating into the Altai Mountains.
由于气候、土壤和水源的变化，山脉在小范围内形成了多种多样的微生境。植物适应这种微生境的关键在于基因变异；然而，通过变异自然积累基因变异的速度很慢，而且往往仅靠变异是不够的。通过杂交进行适应性引种是产生遗传变异的另一种方法。在这里，我们研究了阿尔泰山脉分布的马鞭草亚种（Veronica subg. Pseudolysimachium）的杂交情况，并讨论了其适应作用。为了支持我们关于频繁杂交的假设，我们对来自 10 个物种的 233 个个体和之前根据形态学描述的 7 个假定杂交种进行了数千个 SNPs 的基因分型。我们采用了贝叶斯和似然统计模型，并通过形态计量分析和基因组原位杂交（GISH）来支持我们的结果。结果表明，几乎所有假定杂交种的个体都是 F1 型。GISH 调查强烈支持同源杂交（V. ×schmakovii 起源于 V. longifolia 和 V. porphyriana）。阿尔泰马鞭草物种的分化时间估计在 1-2 百万年前，在此期间基因流动的可能性很大。我们的研究结果还表明，基因流动的方向主要来自当地特有的 V. porphyriana。我们推测，阿尔泰山的西伯利亚大平原和地形多样的前陆为杂交提供了理想的环境，使迁徙到阿尔泰山的低地物种有可能适应性地引入能耐受凉爽气候的等位基因。

Subfamily Cercidoideae is an early‐diverging lineage of Leguminosae, within which the number and classification of genera have been controversial. Cheniella is a recently described genus in the Cercidoideae which requires revision and testing of its monophyly and circumscription. Here we infer the phylogenetic position and infrageneric relationships of Cheniella as well as the intergeneric relationships of Cercidoideae using 48 newly sequenced plastid genomes, including 34 individuals representing all species of Cheniella. Our phylogenetic analyses yield a well‐resolved tree of Cercidoideae with robust support at most nodes. We also present morphological studies through field work and herbarium studies to re‐assess the classification and circumscription of the genus. Based on the results of molecular analyses and morphological studies combined with distribution data, we broaden the circumscription of Cheniella to comprise a total of 15 species and 3 subspecies, including three new species (C. hechiensis, C. longistaminea, C. pubicarpa), one new combination (C. tianlinensis) and one new status and combination (C. longipes).

The use of molecular data in phylogenetic reconstruction during more than three decades has greatly improved our understanding of the macroevolutionary history of the coffee family (Rubiaceae) and has provided a solid basis for improvement of its classification. Based on the results of 130 studies, among them most recent phylogenomic works, we present a consensus phylogeny and a robust classification of Rubiaceae that shed light on the evolutionary success of this highly diverse angiosperm family and can serve as a framework for ecological and evolutionary studies. There are more than 14,000 species and about 580 accepted genera of Rubiaceae that are assigned to 71 tribes, of which 68 are classified in two subfamilies (Dialypetalanthoideae with 38 tribes and Rubioideae with 30 tribes). Three tribes (Acranthereae, Coptosapelteae, Luculieae) remain unclassified as to subfamily. Sixty‐three of these 71 tribes are assigned to nine informal alliances (four in Rubioideae and five in Dialypetalanthoideae). These tribes are listed in alphabetical order within their respective alliances. Five tribes, one (Coussareeae) in Rubioideae and four (Airospermeae, Jackieae, Retiniphylleae, Steenisieae) in Dialypetalanthoideae, are excluded from these alliances due to unclear or conflicting phylogenetic positions. Thirty‐six tribes retain their tribal status but receive new generic limits to remedy their previous para‐ or polyphyletic nature. Twenty‐nine tribes not implemented in previous classifications have been added, of which three (Chioneae, Glionnetieae, Temnopterygeae) are newly described here. Basic information on phylogenies, distributions, former classifications, and useful references to previous works are provided for all accepted tribes, and future perspectives are discussed.

This paper delves into the intricacies of botanical nomenclature, specifically focusing on the interpretation and application of Art. 20.2 of the International Code of Nomenclature (ICN). It critically analyzes the case of Delicata Krammer, against the backdrop of Art. 20.2. The investigation shows that Delicata does not coincide with any established Latin technical term used in morphology and hence fulfills the ICN requirements, confirming its validity. This finding highlights the need for clearer guidelines in distinguishing descriptive Latin terms from technical terms used in morphology. This paper contributes to the ongoing discourse in botanical taxonomy by advocating for revised practices and interpretations of nomenclatural rules, ensuring stability and precision in the naming of taxa.

Berberidopsidales comprises two families: monotypic Aextoxicaceae (Aextoxicon punctatum in Chile and Argentina) and Berberidopsidaceae. The latter includes Australian monotypic Streptothamnus (S. moorei) and Berberidopsis (B. beckleri in Australia and B. corallina in Chile). A new Berberidopsis species from the Central Chilean Andes is here described. Phylogenetic analyses based on nuclear and chloroplast data clarified the relationships within Berberidopsidales. The new species, Berberidopsis granitica, is sister to the Chilean endemic B. corallina, and this clade is sister to the Australian B. beckleri. The dated molecular phylogeny places the split between the South American B. corallina and B. granitica into the late Miocene/early Pleistocene and the split between South American and Australian Berberidopsis to the late Miocene and Pliocene, suggesting transoceanic dispersal rather than vicariance. Climatic niche analyses show two distinct and non‐overlapping climatic niches for the Australian and southern South American species. Berberidopsis granitica and B. corallina also differ clearly in their habitat and morphology, in addition to their climatic niche. Berberidopsis granitica has a very restricted distribution area and grows in the Andes under montane climatic conditions, unique within Berberidopsidales.
小檗科包括两个科：单型的 Aextoxicaceae（智利和阿根廷的 Aextoxicon punctatum）和 Berberidopsidaceae。后者包括澳大利亚的单型 Streptothamnus（S. moorei）和 Berberidopsis（澳大利亚的 B. beckleri 和智利的 B. corallina）。本文描述了一个来自智利安第斯山脉中部的 Berberidopsis 新种。基于核和叶绿体数据的系统发育分析明确了拟小檗属（Berberidopsidales）内部的关系。新种 Berberidopsis granitica 是智利特有种 B. corallina 的姊妹种，该支系与澳大利亚的 B. beckleri 是姊妹支系。根据分子系统发育的年代，南美洲B. corallina和B. granitica之间的分裂发生在中新世晚期/更新世早期，而南美洲和澳大利亚Berberidopsis之间的分裂发生在中新世晚期和上新世，这表明它们是越洋扩散而不是沧海桑田。气候生态位分析表明，澳大利亚和南美洲南部的物种有两个不同的、不重叠的气候生态位。Berberidopsis granitica和B. corallina除了气候生态位不同外，在栖息地和形态上也有明显差异。Berberidopsis granitica 的分布区域非常有限，生长在安第斯山脉的山地气候条件下，在 Berberidopsidales 中独一无二。
