Tlie stems of this plant are usually soli- tary, with long leafy foliar bracts that greatly exceed the individual cymules. For a few years this plant was treated as a variety of C cclosioides. but there is no reason to believe that it is even remotely related to that species. Rydberg described Oreocarya spicata as a new species on the basis of the smooth nutlets. Later it was transferred as a form of O. virgutu. Macbride contended that O. spiaUa was not deserving, even of varietal rank. In obseiving specimens from the type locality about Pikes Peak, it is even more evident that sptaiia is only a form of virgata. 21.
