Epiphyllum flowers

Epiphyllum, or 'orchid cactus', is a family of primarily tree-dwelling tropical ephiphitic cacti.  They are very popular as garden plants.   I photographed the spectacular blossom at upper left in a friend's back yard; the others were growing in my own yard in Riverside, California.
