Discussion
Of conservation concern.
As far as is known, based on field investigations and herbarium collections, Sclerocactus sileri is restricted to northeast Coconino County, Arizona. This enigmatic cactus shares morphologic characteristics with both Sclerocactus whipplei (F. Hochstätter 1996) and S. pubispinus. The floral morphology and color is reminiscent of S. whipplei; however, the adaxial central spine morphology and fruit dehiscence is much like that found in S. pubispinus and S. spinosior. Phylogenetic analyses of chloroplast DNA sequences (J. M. Porter et al. 2000) provided evidence that S. sileri is the sister taxon to a clade including S. brevispinus, S. whipplei, S. cloverae, S. glaucus, S. parviflorus, S. wetlandicus, and S. wrightiae. Therefore, there is no support for immediate links between S. sileri and either S. whipplei or S. pubispinus.
