III. Telia amphigenous, scattered, very small, punctiform, often confluent, early naked, 
somewhat pulverulent, blackish, ruptured epidermis inconspicuous; teliospores semi-opaque, 
broadly ellipsoid, 28-32 by 32-404, rounded at both ends, strongly depressed when dry, 
slightly or not constricted at septum; wall dark chocolate-brown, smooth, moderately thick, 
2.5-3 w, slightly thicker at apex and over pore of lower cell, 4-64; pedicel colorless, firm, 
stout, 7-9 u at apex, swelling below, 10-12 4, granulose when dry, the wall thin, 1-1.5 x, 
once to thrice length of spore.

II. Uredinia hypophyllous, few, scattered, round, small, 0.2-0.4 mm. in diameter, early 
naked, pulverulent, dark cinnamon-brown, ruptured epidermis conspicuous; urediniospores 
greatly compressed laterally, somewhat flattened beneath, appearing somewhat reniform when

end, distinctly constricted at septum; wall chestnut-brown, uniformly 1.5-2 » thick or thick- 
ened to 3 u at pores, smooth, the pore of upper cell often placed laterally, pore of lower cell 
usually about half way between septum and pedicel; pedicel colorless, deciduous, or equaling 
the spore in length.

lighter in color at apex, smooth; pedicel colorless, flexuous, short, deciduous, or equaling 
the spore, often attached obliquely.
