Abstract:

 

In Turkey, the genus Chrysophthalmum Sch.Bip. ex Walp. is represented by 3 taxa, namely Chrysophthalmum montanum (DC.) Boiss., C. dichotomum Boiss. & Heldr. and C. gueneri Aytaç & Anderb.. C. montanum is herbaceous plant that grows on rock cracks and limestone cliffs, in the eastern and southeastern regions of Turkey. In this study, pollen and cypsela morphology of this species was investigated with light microscope (LM) and scanning electron microscope (SEM). Further, the previous description of the species has been expanded. The pollen grains of the species are tricolporate, radially symmetrical, isopolar, shape oblate-spheroidal, ornamentation echinate-perforate. The cypselae of C. montanum are brownish, oblong, and glabrous. Pappus uniseriate, with 25-49 bristles, smooth, white and free at base.

 

Türkiye’de Chrysophthalmum Sch.Bip. ex Walp. cinsi Chrysophthalmum montanum (DC.) Boiss., C. dichotomum Boiss. & Heldr. and C. gueneri Aytaç & Anderb. olmak üzere 3 taksonla temsil edilmektedir. C. montanum, Türkiye'nin Doğu ve Güneydoğu bölgelerinde kaya çatlakları ve kalker kayalıklarında yetişen otsu bir bitkidir. Bu çalışmada, bu türün polen ve sipsela morfolojisi ışık mikroskobu (LM) ve taramalı elektron mikroskobu (SEM) ile incelenmiştir. Ayrıca, türün önceki deskripsiyonu genişletilmiştir. Türün polen taneleri trikolporat, radial olarak simetrik, izopolar, şekli oblat-sferoidal, süslemesi ekinat-perforattır. C. montanum'un sipselası kahverengimsi, dikdörtgen ve tüysüzdür. Pappus bir sıralı, 25-49 kıllı, pürüzsüz, beyaz ve tabanda serbesttir.
