On the cover: Irwin Lightstone captured this magnified image of a Pseudolithos migiurtinus in flower. His unusual photographic techniques enable him to create masterful images that are seldom witnessed with the naked eye. Check out his article on page 220 of this issue!

From Irwin: For years, I grew my Pseudolithos migiurtinus because of it's unique texture and chunky growth pattern. When it flowered, the inflorescence looked like cute miniatures of other stapeliads, but not really important. They were just too small to really see. By magnifying them 3.75x, their other-wordly details emerge. In a family where so many of the larger stapeliads have achieved a legendary status despite their smell, the flowers of Pseudolithos migurtinus have their own unique charm. To extend the field-sharp focus, multiple images were merged into a single image by using a process known as focus stacking.
