Discussion
Most chromosome counts are 2n = 26; there are reports of 2n = 22, 24, and 32 (Á. Löve and D. Löve 1975b). The veracity of the latter reports has not been confirmed. Moneses uniflora has been used by different Native American tribes as a dermatological aid, cold remedy, throat aid, and analgesic (D. E. Moerman 1998).
