Karyological studies in Hieracium baeticum (Asteraceae) from the "Parque Natural de la Sierra de Grazalema" (Southern Spain)
(International Foundation pro Herbario Mediterraneo, 1994)
Hieracium baeticum is a triploid (2n = 27) species restricted to Iimestone mountains in Sand E Spain. 80th developing capitula and root tips from seedlings were used for the study. The karyotype suggests an allopolyploid ...

Chemical imitation of yeast fermentation by the drosophilid-pollinated deceptive trap-flower Aristolochia baetica (Aristolochiaceae)
(Elsevier, 2024-05)
Deceptive flowers, unlike in mutualistic pollination systems, mislead their pollinators by advertising rewards which ultimately are not provided. Although our understanding of deceptive pollination systems increased in ...

(Nature Publishing Group; Nature Portfolio, 2024-01-09)
Since the insights by Charles Darwin, heterostyly, a floral polymorphism with morphs bearing stigmas and anthers at reciprocal heights, has become a model system for the study of natural selection. Based on his archetypal ...
