Spach (Labiatae) from Andean South America was long held to be closely related to Macaronesian Bystropogon L'Her. or to North American Pycnanthemum Michx. The possibility of a close relationship to elements of South American Satureja/Clinopodium s.l. is here proposed for the first time, and a phylogenetic analysis of nrITS data is employed to test the competing hypotheses. For Minthostachys and its putative closest relatives, the possible evolution of morphological characters is investigated with a cladistic analysis. The results suggest that Minthostachys is nested in a clade of South American Mentheae, and probably in the former genus Xenopoma Willd., a group of small-flowered, bee-pollinated species currently included in Clinopodium L.. Minthostachys is considered monophyletic based on nrITS data and its scandent habit. VL - 270 UR - http://www.springerlink.com/content/m572q7rj3u8225h8/ ER -
