Euonymus, studies of fruit and seed characters of selected species, Bernd Schulz, translated by Wolfgang Bopp, 2006 PDF
Euonymus species are particularly prized for their decorative fruits. This work describes and illustrates (in water colour), the fruits and seeds of 30 commonly cultivated species found in Central European plant collections. The text discusses the criteria for species differentiation. As well as the shape of the fruits and seeds, seed colouration is described and compared to several published accounts in an attempt to correct previous misconceptions.
