An interim report is presented on the population dynamics of Dichromanthus michuacanus and Hexalectris revoluta in southeastern Arizona. Several colonies of each species have been monitored annually to evaluate total number of plants appearing and blooming patterns. The objective of the study is to determine if plants appear every year; if plants bloom on successive years; length of time between blooming events for a given plant; and long-term population dynamics. As of 2003, the study has been ongoing for 9 years. Interim results indicate that plants from both species are unreliable bloomers in successive years. Blooming can stunt succeeding growth on D. michuacanus, and plants of H. revoluta do not even appear above ground for several years after blooming.
