Abstract

Abstract Lithospermum L. (Boraginaceae) includes approximately 60 species of which 43 occur in Mexico, with 32 endemic to the country. Through morphological and molecular investigations, the species of the genus are taxonomically revised. A broad generic circumscription is recognized and includes species traditionally recognized as members of Lithospermum as well as other New World Lithospermeae. Three new species are described from northern Mexico—Lithospermum chihuahuanum J. I. Cohen, Lithospermum kelloggianum J. I. Cohen, and Lithospermum tenerum J. I. Cohen—and each is known from only its type specimen. Lasiarrhenum confundum B. L. Turner is transferred to Lithospermum confundum (B. L. Turner) J. I. Cohen on the basis of flowers similar to those of Lithospermum trinervium (Lehm.) J. I. Cohen. The type for Pentalophus A. DC. is designated. Lectotypes are designated for Lithospermum albicans Greene [= Lithospermum incisum Lehm.], Lithospermum approximatum Brand [= Lithospermum distichum Ortega], Lithospermum breviflorum Engelm. & A. Gray [= Lithospermum incisum Lehm.], Lithospermum cobrense Greene, Lithospermum cognatum Greene ex Spengle [= Lithospermum multiflorum Torr. ex A. Gray], Lithospermum euryphyllum Brand [= Lithospermum oblongifolium Greenm.], Lithospermum galeottii Brand [= Lithospermum calycosum (J. F. Macbr.) I. M. Johnst.], Lithospermum gentianoides Brand [= Lithospermum obovatum J. F. Macbr.], Lithospermum hoyasense Brand [= Lithospermum calcicola B. L. Rob.], Lithospermum laevigatum Sessé & Moc. [= Lithospermum distichum Ortega], Lithospermum madrense Brand [= Lithospermum calcicola B. L. Rob.], Lithospermum matamorense DC., Lithospermum nelsonii Greenm., Lithospermum obtusiflorum Sessé & Moc. [= Lithospermum discolor M. Martens & Galeotti], Lithospermum sordidum Brand [= Lithospermum distichum Ortega], and Lithospermum spathulatum M. Martens & Galeotti [= Lithospermum distichum Ortega]. Lithospermum viride Greene is neotypified.

墨西哥石芋属植物(Boraginaceae)的订正

摘要紫草属植物(Boraginaceae)约60种，其中43种产自墨西哥，32种为墨西哥特有。通过形态学和分子学的研究，对该属的种进行了分类修正。广泛的属界已被确认，包括传统上被认为是石芋科成员的物种以及其他新世界石芋科。在墨西哥北部描述了三个新种——chihuahuaum J. I. Cohen, Lithospermum kelloggianum J. I. Cohen和Lithospermum tenerum J. I. Cohen，每一种都仅从其模式标本中已知。由于花与紫花草(Lithospermum trintervium, Lehm)的花相似，因此将Lasiarrhenum conundum b.l. Turner改为Lithospermum conundum (b.l. Turner) j.i.

期刊介绍： The Annals of the Missouri Botanical Garden is a quarterly international journal primarily devoted to systematic botany and evolutionary biology. We encourage submissions of original papers dealing with significant advances in the taxonomy, phylogeny, biogeography, paleobiology, and evolution of plants, and in conservation genetics and biology, restoration ecology, and ethnobiology, using morphological and/or molecular characters, field observations, and/or database information. We also welcome reviews and papers on conceptual issues and new methodologies in systematics. Important floristic works will also be considered. Symposium proceedings discussing a broader range of topical biological subjects are also published, typically once a year. All manuscripts are peer-reviewed by qualified and independent reviewers.
