Cover illustration: So many photogaphs of Discocactus horstii have been published that we hesitated to present another - yet it is indeed a lovely and intriguing species. An additional excuse is that our photo is an unusually fine one, the work of Darl Bickel of Richmond, Virginia. This gem of a species was found in Minas Gerais, Brazil, and first described in 1973. Because of its dark brownish epidermis and radially segmented body, it more closely resembles some coral-reef creature than it does a plant. The flowers, though small, are otherwise typical of the genus in being nocturnal and deliciously fragrant.
