Abstract

Behria is a genus of petaloid geophytes endemic to the Cape Region of Baja California Sur, Mexico. It belongs to the Milla clade within the subfamily Brodiaeoideae of the Asparagaceae family. Currently, Behria tenuiflora is the only recognized species within this genus. In our methodological approach, we considered two distinct floral morphotypes: Group A consists of populations found at lowland elevations (10–150 m), while Group B comprises plants growing at mid to high elevations (400–2060 m). The aim of our study was to investigate whether there are discernible morphological differences and correlations with climate variables between Behria Group A and Group B. To address this, we measured nine quantitative characters for 94 plants from seven populations of Behria tenuiflora. Our findings revealed statistically significant differences (P < 0.05) in pedicel length, perianth length, perianth base diameter, and perianth aperture diameter of the analyzed Behria groups. Based on these results, we propose the recognition of Behria leonis as a new species. Additionally, we provide a morphological key for distinguishing Behria and Bessera genera, along with illustrations, a distribution map, and photographs.

来自墨西哥下加利福尼亚半岛的 Behria（天门冬科，Brodiaeoideae）隐匿新种

Behria 是墨西哥南下加利福尼亚开普地区特有的瓣状地肤植物属。它属于天门冬科 Brodiaeoideae 亚科 Milla 支系。目前，Behria tenuiflora 是该属中唯一被认可的物种。在研究方法上，我们考虑了两种不同的花形态：A 组包括在低海拔地区（10-150 米）发现的种群，B 组包括生长在中高海拔地区（400-2060 米）的植物。我们的研究旨在探讨贝里亚花 A 组和 B 组之间是否存在明显的形态差异以及与气候变量的相关性。为此，我们测量了贝里亚花 7 个种群 94 株植物的 9 个定量特征。我们的研究结果表明，所分析的贝里亚群体在花梗长度、花被长度、花被基部直径和花被孔径方面存在显著差异（P < 0.05）。基于这些结果，我们建议将 Behria leonis 确认为一个新种。此外，我们还提供了区分 Behria 和 Bessera 属的形态学检索表，以及插图、分布图和照片。

期刊介绍： Phytotaxa is a peer-reviewed, international journal for rapid publication of high quality papers on any aspect of systematic and taxonomic botany, with a preference for large taxonomic works such as monographs, floras, revisions and evolutionary studies and descriptions of new taxa. Phytotaxa covers all groups covered by the International Code of Nomenclature foralgae, fungi, and plants ICNafp (fungi, lichens, algae, diatoms, mosses, liverworts, hornworts, and vascular plants), both living and fossil. Phytotaxa was founded in 2009 as botanical sister journal to Zootaxa. It has a large editorial board, who are running this journal on a voluntary basis, and it is published by Magnolia Press (Auckland , New Zealand). It is also indexed by SCIE, JCR and Biosis. All types of taxonomic, floristic and phytogeographic papers are considered, including theoretical papers and methodology, systematics and phylogeny, monographs, revisions and reviews, catalogues, biographies and bibliographies, history of botanical explorations, identification guides, floras, analyses of characters, phylogenetic studies and phytogeography, descriptions of taxa, typification and nomenclatural papers. Monographs and other long manuscripts (of 60 printed pages or more) can be published as books, which will receive an ISBN number as well as being part of the Phytotaxa series.
