IDENTITY OF MERTENSIA OBLONGIFOLIA (NUTT) G. DON (BORAGINACEAE) AND ITS ALLIES IN WESTERN NORTH AMERICA

Ahmed M. Warfal

ABSTRACT.-The current status of Mertensia oblongifoUa (Nutt.) G. Don and its allied taxa is surveyed. On the bases of continuously coherent morphological characters and/or regionally correlated variations, more than 30 taxa, including , subspecies, varieties, and 1 forma, previously considered different from M. oblongifolia, are now placed under synonymy of this species. Those taxa currently known as M. fusiformis Greene, M. bakeri Greene, and M. bakeri var. osterhoutii Williams are among the new synonyms. Typification, , and morphological problems ofM. oblongifo­ lia are discussed.

Key words: Mertensia oblongifolia, typification, Wxorwmy, morphology, allied taxa.
