HUSEYIN INCEER SEMA HAYIRLIOGLU‐AYAZ 《Botanical journal of the Linnean Society. Linnean Society of London》2008,158(4):696-700
A new species of Tripleurospermum Sch.Bip., Tripleurospermum ziganaense Inceer & Hay?rl?oglu‐Ayaz (Asteraceae, Anthemideae), is described and illustrated. The species grows in open places, on rocky slopes and on roadsides in north‐east Anatolia, Turkey. The diagnostic morphological characters that distinguish it from closely related taxa are discussed, and its conservation status is indicated. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 158 , 696–700. 相似文献

Twenty-two chromosome counts of 19 taxa in the tribe Anthemideae of the family Asteraceae are reported from north-east Anatolia, Turkey. The taxa belong to the subtribes Achilleinae (four Achillea taxa), Anthemidinae (five Anthemis taxa), Artemisiinae (two Artemisia species), Leucantheminae (one Lecanthemum species), Matricariinae (two Tripleurospermum species) and Tanacetinae (five Tanacetum taxa). Six counts are new reports, seven are not consistent with previous counts, and the remainder are confirmations of very limited previous data. Most of the populations of Anthemideae studied have the basic number x = 9, with ploidy levels ranging from 2 x to 7 to 8 x , but dysploidy is also present, with one diploid species, Artemisia austriaca , having x = 8. © 2007 The Linnean Society of London, Botanical Journal of the Linnean Society , 2007, 153 , 203–211. 相似文献
