"Uredospores yellowish-brown, globose, subglobose to ellipsoid 

 finely echinulate, with two germ-pores on one face, 25-27 x 19-24 fi.

 lent, dark-brown, orbicular to elliptic, soon naked, y^-l mm. 



"Teleutospores intemiixed with uredospores, chestnut-brown, 

 ellipsoid, rounded at both ends, unthickened at apex, not constricted 

 at septum, delicately warted, germ-pores conspicuous, 30-40 x 

 22-30 fx ; average 32 x 24 /x. ; epispore about 3 /x thick ; pedicel hya-

 by Burrill as follows : 



" II, III. Mostly epigeno'us, sometimes amphigenous. Sori small,

 crowded, rarely confluent on the leaves, but on the sheaths forming 

 long, irregular lines, black, rather early erumpent, but long sur-

 spore rather thin, sharply but minutely echinulate, 15-24 /a; teleuto- 

 spores elliptical or broadly clavate, slightly constricted, vertex 

 strongly thickened and obtusely pointed or rounded, narrowed be- 

 low, smootli, not deeply colored, 1-5-21 by 30-48 /i, ; pedicel once to
