From near extinction to diversification by means of ashift in pollination mechanism in the gymnosperm relict Ephedra (Ephedraceae, Gnetales) by Bolinder, Kristina, Humphreys, Aelys M., Ehrlén, Johan, Alexandersson, Ronny, Ickert-Bond, Stefanie M., Rydin, Catarina

“…Pollination in gymnosperms is usually accomplished by means of wind, but some groups are insect-pollinated. We show that wind and insect pollination occur in…”
