Carex quixotiana (Cyperaceae), a new Iberian endemic from Don Quixote's land (La Mancha, S Spain)

Опубликована: Дек. 30, 2022

Despite centuries of intense work, the basic taxonomic knowledge flora Iberian peninsula is still incomplete, especially for highly diverse and/or difficult genera such as Carex . In this study, we conducted an integrative systematic study based on molecular, morphological and cytogenetic data to elucidate status several problematic populations from La Mancha region (S Spain) belonging sect. Phacocystis These have been traditionally considered uncertain adscription, but close C. reuteriana. A detailed was performed with 16 sampled (Sierra Madrona, Montes de Toledo) in order compare them other species. addition, a phylogenetic analysis using two nuclear (ITS, ETS) plastid ( rpl 32‐ trn L UAG , ycf 6‐ psb M) DNA regions, including representatives whole We found significant degree molecular differentiation that supports recognition these new endemic species, quixotiana. Our results reveal that, unexpectedly, quixotiana more closely related nigra than reuteriana basis relationships chromosome number. However, overall appearance ecological preferences were misleadingly suggesting affinities contrasting patterns reflect complexity remark need approaches disentangle fiendish evolutionary scenarios.
