Revised lectotypification of the name Calendula maritima (Asteraceae)
2012
Troia, Angelo, Greuter, Werner, Raimondo, Francesco Maria (2012): Revised lectotypification of the name Calendula maritima (Asteraceae). Phytotaxa 71 (1): 48-51, DOI: 10.11646/phytotaxa.71.1.9, URL: http://biotaxa.org/Phytotaxa/article/view/phytotaxa.71.1.9
Inflorescence scents of Calendula maritima, C. suffruticosa subsp. fulgida, and their hybrid
2018
Premise of research. Hybridization is an important driver of plant evolutionary processes. By attracting the same pollinators to different species, floral scents may be involved in the formation of hybrids and breakdown of species boundaries. In contrast, by attracting a different suite of pollinators to hybrids and their parents, floral scents are believed to contribute to speciation processes initiated by hybridization events. Scents may or may not differ between the hybrids and their parents, but little is known about the scent chemistry of parental species and their hybrids. Methodology. We studied the inflorescence scents of parental Calendula maritima and C. suffruticosa subsp. fulgid…
Strategie di gestione delle popolazioni di Calendula maritima Guss. (Asteraceae)
2011
Dopo avere brevemente esaminato la situazione in cui si trovano le popolazioni naturali di C. maritima, specie rara ed endemica della provincia di Trapani (Sicilia), si discute delle più opportune strategie di gestione al fine di assicurarne la conservazione. Vengono infine identificate le principali minacce e proposte le conseguenti necessarie azioni di tutela.
Hybridization and competition between the endangered sea marigold (Calendula maritima, Asteraceae) and a more common congener
2013
Occurrences of hybridization between the rare, endangered Sicilian endemic, Calendula maritima, and other congeners in the wild have been suspected by several authors, but never demonstrated. In San Cusumano (Trapani), one of the only three Sicilian mainland populations, C. maritima occurs in close proximity to the more common congener C. suffruticosa subsp. fulgida, and individuals morphologically intermediate between the two taxa have been observed. In order to determine whether hybridization is occurring at this site, and, if so, begin to assess the impact it could have on C. maritima, two independent tests of hybridity were conducted by studying (1) the pollen morphology and viability a…
