O. Pycnia amphigenous, among or opposite the aecia, scattered, inconspicuous, honey- 
yellow becoming brown, globoid, 85-150 u in diameter by 110-170 » high; ostiolar filaments 
30~65 « long. 
I. Aecia amphigenous, chiefly hypophyllous, scattered, from a diffused mycelium, numer- 
ous, often covering the entire leaf-surface, cupulate or sometimes short-cylindric, 0.2-0.5 mm. 
across; peridium white, the margin recurved, lacerate; peridial cells rhomboidal, 13-22 by 
22-36 wu, overlapping, the outer wall 5-10 » thick, transversely striate, the inner wall thinner, 
3-6 4, moderately verrucose; aeciospores irregularly globoid, angular, or ellipsoid, 13-20 by 
13-23 », (usually only up to 20 yw in length); wall colorless, thin, 1 », minutely verrucose. 
II. Uredinia amphigenous, often only hypophyllous, numerous, scattered, occasionally 
confluent, roundish, small, 0.1-0.8 mm. across, rather early naked, pulverulent, cinnamon- 
brown, ruptured epidermis noticeable; urediniospores ellipsoid, obovoid or globoid, flattened 
slightly on two opposite sides, 15-26 by 19-31 »; wall cinnamon-brown, somewhat variable in 
thickness, 1.5-3 », moderately or sometimes closely echinulate, the pores 2, equatorial, rarely 
slightly superequatorial, in lighter-colored areas in the flattened sides. 
Ill. Telia amphigenous, sometimes caulicolous, numerous, scattered or sometimes con- 
fluent, roundish, rather small, 0.2-1 mm. across, early naked, pulvérulent or sometimes com-
