摘要

摘要我们检验了一种假设，即以前被称为Thesium sp. d.a.z igila &上午Muasya 1006对科学来说是新的。我们将其正式描述并命名为schmielelae。新种为直立至近直立小灌木，高约20厘米，外表白霜，茎横截面圆柱状，叶苞片，小苞片肉质。分子和形态学资料支持将schmiedelae放置在环孢菊亚属剖面中。新物种是Knersvlakte自然保护区特有的物种，出现在土壤独特的石英岛屿上。由于受干旱、石英区生境破碎化严重、种群规模小、占用面积小等因素的威胁，初步评价为易受保护。

Thesium schmiedeliae (Santalaceae), a new species from Knersvlakte quartz fields, South Africa

Summary We test the hypothesis that the Thesium (Santalaceae) collection previously known as Thesium sp. D.A.Zhigila & A.M.Muasya 1006 is new to science. We formally describe and name it T. schmiedeliae . The new species is an erect to suberect shrublet, c. 20 cm tall, glaucous in overall appearance, with stems terete in transverse section, and leaves bracts, and bracteoles succulent. Molecular and morphological data support the placement of T. schmiedeliae in subgenus Frisea section Annulata . The new species is endemic to the Knersvlakte Nature Reserve and occurs in the edaphically unique quartz islands. Thesium schmiedeliae is preliminarily assessed for conservation purposes as Vulnerable as it is threatened by drought, severe fragmentation of its quartz-field habitat, small population size, and a small area of occupancy.

期刊介绍： Kew Bulletin is an international peer-reviewed journal for the taxonomy, systematics and conservation of vascular plants and fungi. Papers on conservation, evolution, palynology, cytology, anatomy, biogeography and phytochemistry are considered, where relevant to taxonomy and systematics. Review papers on topics appropriate to the journal are invited. The journal is richly illustrated with line drawings and photographs, and also features a Book Review and Notices section. Four parts (c. 640 pp) are published each year.
