Korthalsella flowers

Korthalsella flowers

Korthalsella species are differentiated from leafless Viscum spp. by ebracteate, trimerous flowers (Viscum spp. have bracteate, tetramerous flowers). They are monoecious and New Zealand species have two female flowers on each side of axillary male flower (see below). Each floral whorl has two such sets thus having two male and eight female flowers in each whorl. Each set is separated by tufts of reddish brown trichomes. 

All three anthers in the male flowers of Korthalsella species fuse to form a disc like structure called as synandrium and the pollen grains are exuded from a central pore in nectar droplets (note a tiny nectar droplet in the lower male flower and the central pore of synandrium in the upper flower in the picture above).
