Ethnobotanical Research and Compilation of the Medicinal Uses in Spain and the Active Principles of Chiliadenus glutinosus (L.) Fourr. for the Scientific Validation of Its Therapeutic Properties.

The species Chiliadenus glutinosus (L.) Fourr. has a large number of therapeutic uses reported in the traditional Spanish medicine. The growing interest in preserving the ethnopharmacological knowledge related to the botanical diversity existing in Spain and the interest in achieving scientific validation of the therapeutic properties of medicinal species has led to the development of this study. To do it, all the known medicinal uses of Ch. glutinosus in Spain were compiled, then an exhaustive bibliographic research on its chemical composition was carried out, and finally, an in silico validation of the bioactive phytochemicals present in a higher proportion in the essential oil of Ch. glutinosus: camphor, borneol, lucinone, glutinone, quercetin, kutdtriol, and kaempferol; in an attempt to justify the reported traditional uses of the species. It was found that much of the traditional medicinal uses of Ch. glutinosus, along with the biological activity of its phytochemicals, are supported by scientific evidence. The results place this species in a prominent position to initiate possible lines of research to develop new, more effective drugs and improve therapies to treat conditions and diseases that affect the different organic systems of the human being.

A new species of perennial Bromus (Bromeae, Poaceae) from the Iberian Peninsula.

During a survey of the genus Bromus for the ongoing Flora Iberica, B.picoeuropeanus sp. nov., a new orophilous species of perennial Bromus from Picos de Europa National Park, was found, and it is described and illustrated here. This new species belongs to the Bromuserectus complex and differs from the other perennial species of this group occurring in the Iberian Peninsula in its well-developed rhizome, the small innovation leaves and all peduncles and branches shorter than the spikelets. B.picoeuropeanus grows on calcareous stony soils associated with dry places. We provide a description and illustrations of the new species and an identification key for the most related European perennial species belonging to the complex.

Typification of eight current and seven related names and a new section in the genus Bromus (Bromeae, Pooideae, Poaceae).

During our nomenclatural revision of the genus Bromus L. (Poaceae) for Flora Iberica, we found that several names were still untypified: nine names in current use or their basionyms and five synonyms. Typifications are still needed since stabilising the names will facilitate their use. We propose lectotypes for Bromusalopecuros Poir., B.contortus Desf. (and the superfluous B.alopecuroides Poir.), B.benekenii (Lange) Trimen, B.intermediusGuss.subsp.divaricatus Bonnier & Layens, B.molliformis J.Lloyd ex Billot, B.lepidus Holmb., B.lepidus f. lasiolepis Holmb., Bromussubg.Stenobromus (Griseb.) Hack. and Bromussect.Stenobromus Griseb. Neotypes for B.erectus Huds. and B.ramosus Huds. and an epitype for B.intermediussubsp.divaricatus Bonnier & Layens are proposed. In addition, we identify an isoneotype for B.erectus and isolectotypes for B.lepidus and B.lepidusf.lasiolepis. The area inhabited by the typified taxa includes both Africa and Europe. All the selected types are in agreement with the current use of the names and, thus, our selections contribute to stabilising the nomenclature of the genus Bromus. A discussion is provided to justify the selections. In addition, we typified two supraspecific names B.subg.Stenobromus and B.sect.Stenobromus. Finally, a new section, B.sect.Penicillius Llamas & Acedo, is described.
