On the cover. Under high magnification, the spine pattern at the apex of Turbinicarpus pseudopectinatus is revealed in its full intricacy. Tight rows of pectinate spines and white bristles nearly hide the body, even at high magnification. Irwin Lightstone captured this compelling image of approximately 1.5 cm of this plant in his greenhouse in Dallas, Texas, using an enlarging lens mounted on a bellows. With the camera and bellows unit affixed to a steady tripod, Irwin took 49 separate shots, varying only the point of focus, and combined them into this infinite depth of field image. See p 137 to learn more.
Like all other species ofTurbinicarpus, T. pseudopectinatus is internationally protected under Appendix I of CITES. It grows in grasslands and pinyon-juniper woodlands in Tamaulipas and Nuevo Leon, Mexico. With its small size, beautiful spination and easy growing habit, Turbinicarpus pseudopectinatus is a welcome addition to the greenhouse.
