Flower morphology of the resurrection plant Chamaegigas intrepidus Dinter and some of its potential pollinators

Differences in the diversity and composition of the pollinator assemblage of two co-flowering congeneric alpine wallflowers, Erysimum nevadense and E. baeticum

“…Pollination by beetles has been shown in a number of plants, most times in highly specialized relationships (Anstett, 1999;Franz, 2007;Gibernau et al, 1999;Hemborg and Bond, 2005;Ratnayake et al, 2006;Terry et al, 2005;Woitke et al, 2006). Nevertheless, generalist plants mostly pollinated by beetles have been also reported (Daphne laureola, Alonso, 2004;Romulea spp., Goldblatt et al, 2002;Shorea parviflora, Sakai et al, 1999).…”

Visitor diversity and pollinator specialization in Mediterranean legumes

“…were able to trigger the floral explosive mechanism. A peculiar situation characterizes S. junceum: almost only big Xylocopa bees can provoke flowers' opening by explosive mechanism, denoting a high level of specificity; however, the most abundant insects observed touching the reproductive flower parts were coleopterans that might accidentally contribute to pollen transfer, despite their commonly known pollen-eating habit (Faegri and Van der Pijl, 1971;Woitke et al, 2006). Several species of beetles have been observed also on G. radiata, but in this case their abundance was very low compared to that of main pollinators (Bombus spp.).…”
