Cytotaxonomic investigations on Allium valdecallosum (Amaryllidaceae), a critical species endemic to Morocco
2018
Allium valdecallosum is a critical and poorly known species endemic to Morocco. Its diagnostic features, karyology, seed testa micro-morphology, leaf anatomy, ecology, distribution, conservation status, and taxonomic relationships are examined here.
Allium moly subsp. glaucescens (Asparagaceae), a new subspecies from the Iberian Peninsula
2015
Allium moly subsp. glaucescens is described as a new subspecies from the Iberian Peninsula. Different morphological characters from populations located in Valencia (Spain) are evidenced. Lower size of plants, smaller and narrower leaves, of noticeably bluish-green color (glaucous-pruinose), smaller and less flowers in the umbel-inflorescence are characteristic of the new subspecies. Ecology, habitat, cultivation and chemotaxonomy have also been considered and discussed in this work.
Allium nazarenum (Amaryllidaceae), a new species of the section Codonoprasum from Israel
2017
Allium nazarenum, a new species of A. sect. Codonoprasum, is described and illustrated from Israel. Within this species, two well distinct subspecies have been recognized, represented by the subsp. nazarenum and subsp. ramonense respectively. The first one occurs in northern and central Israel, which falls within the Mediterranean bioclimate, while the second one is circumscribed to the Negev desert. Both taxa are diploid with 2n = 16 and are found on various substrata usually in the batha or steppic plant communities. This species shows close relationships with the species belonging to the A. staticiforme group, from which it differs in several relevant diacritic features. Its morphology, …
