The rust genus Uropyxis nad the position of Diphysa (Leguminosae)
Acta botanica neerlandica , Volume 31 - Issue 1/2 p. 135- 136
The rust genus Uropyxis Schroeter has been monographed by Baxter (1959) and reported to be composed of thirteen species. If three atypic species, approaching Dipyxis Cummins & Baxter are removed (Savile 1979), the genus is confined to host plants in two related tribes of the Leguminosae, viz. Aeschynomeneae and Amorpheae, and the genus Diphysa Jacq. The related genus Phragmopyxis Dietel infects hosts in the genera Cracca (Benthamantha) and Coursetia (both Robiniae) (Arthur 1934) in Central America and the unrelated genus Cassia in Africa.
