Distribution C • Great Plains Flora Association 1977 outside R2 • Pinkava 1976 Confidence in Rank High or Medium or Low Evaluator was unable to find any direct information on species’ dispersal capability [rank D]. However, species is presumably wind dispersed and is found only in rocky prairies and breaks in the s-most part of R2 3 [rank B; see sections 1 and 7]. • Freeman 1989 Dispersal D/B Capability Confidence in Rank High or Medium or Low Species is most likely historically rare in R2, where it is at the ne limit of its range [see section 1]. In KS, species is apparently limited to rocky prairie and breaks along the n side of the Cimarron River.

Presumably, the populations themselves have also suffered • Freeman 1989 Population D/A decline from this disturbance, but further investigation is warranted [rank A is qualified]. Trend in R2 Confidence in Rank High or Medium or Low Observation of herbarium specimen labels at KANU reveal that species is found in rocky shortgrass prairies 6 and on rocky breaks of both sandy and calcareous composition.
