bjpt-26074	Bona, Mehmet	Systematic implications of achene characteristics in genera Centaurea L., Cyanus Mill., Psephellus Cass. and Rhaponticoides Vaill. (Asteraceae)	2015	12	.pdf	application/pdf	3358	342	65	SEM studies showed eight different types of achene surface patterns for the studied taxa: Glebulate, glebulate-ruminate, reticulate, ribbed, ruminate, smooth, smooth-glebulate and undulate. Though previous studies support the use of achene surface patterns as diagnostic characters at species and subspecies levels for the genus Centaurea s.l., understanding the importance of these characters at generic and subgeneric levels requires further studies (Uysal et al., 2005; Çelik et al., 2005a, b; Aksoy et al., 2010; Okay and Demir, 2010; Shabestari et al., 2013; Bona, 2014; Candan et al., 2015).	cache/bjpt-26074.pdf	txt/bjpt-26074.txt
