Douglas deweya C. Yen, J.L. Yan, & B.R. Baum, Canadian Journal of Botany, 1 April 2005.
"The new genus Douglasdeweya C. Yen, J.L. Yang. & B.R. Baum is based on results from cytogentical and morphological findings - PPStSt - genome - and is segregated from the genus Pseudoroegneria StSt and StStSt genome. Several characters, such as erect spike with very finely spinulos pubescence along the two main angles of the rachis, and glumes and lemmas with a very strong midrib forming a keel-like structure distinguish Douglasdeweya from Pseudoroegneria, which has a rather lax spike, a rachis that is glabrous along the two main angles, and glumes and lemmas without a keel-like structure. The genus is named in ememory of Dr. Douglas R. Dewey, an outstanding scientist who worked on the biosystematics of the perennial Trtiticeae. Two species are described, one of which is Douglasdeweya wangyii C. Yen, J.L. Yang. & B.R. Baum and he other a new combintation Douglasdeweya deweyi (K.B. Jensen, S.L. Hatch, & J.K. Wipff) C. Yen, J.L. Yang. & B.R. Baum. A key to the two species is provided, together with details on their taxonomy, nomenclature, distribution, and cytology".
