II. Uredinia hypophyllous, scattered, roundish, punctiform, minute, 0.1-0.2 mm. across,

roundish, small, 0.2-0.3 mm. across, rather early naked, dark chestnut-brown, ruptured 
epidermis inconspicuous; paraphyses peripheral, hyphoid, colorless, thin-walled, short and 
inconspicuous; teliospores oblong, 21~27 by 40-48 y, slightly constricted at septum, rounded

semi-hyaline umbo, minutely verrucose above appearing smooth; pedicel colorless, fragile, 
two thirds length of spore or less.

O. Pycnia epiphyllous, few, scattered among the uredinia, small, punctiform, honey- 
yellow, becoming brown, globoid, 112 » broad by 120-130 uw high; ostiolar filaments free. 
II. Uredinia of the primary form chiefly epiphyllous, rather numerous, crowded in groups 
up to 4 mm. in length, often confluent, small, round, 0.3—0.5 mm. across, rather early naked, 
pulverulent, cinnamon-brown, ruptured epidermis inconspicuous; secondary uredinia am- 
phigenous, gregarious like the primary form, on yellow spots, or more often scattered, small, 
0.2-0.5 mm. across, ruptured epidermis often conspicuous; wurediniospores of both forms 
obovoid or broadly ellipsoid, 20-26 by 22-30 »; wall cinnamon-brown, 1.5—-3 » thick, moder- 
ately or sparsely and prominently echinulate, the pores 3, approximately equatorial. 
III. Telia amphigenous and caulicolous, on the leaf-blades often gregarious or confluent 
in groups 0.5-1.5 mm. across, more often scattered, round, 0.2—0.5 mm. across, on the stems 
fusiform, 10-30 mm. long, early naked, becoming somewhat pulverulent, dark chocolate- 
brown, ruptured epidermis noticeable when epiphyllous, inconspicuous when hypophyllous; 
teliospores oblong or ellipsoid, often irregular, 20-28 by 30-45 », somewhat longer and nar- 
rower in caulicolous sori, 19-26 by 40-58 yu, obtuse or rounded above, rounded or narrowed 
below, slightly or not constricted at septum (more frequently so in catllicolous form) ; wall light 
chestnut-brown, minutely verrucose, often appearing smooth, moderately thick, 1.5-3 u, 
thicker at apex, 5-10 », concolorous or often slightly lighter above; pedicel colorless, slender, 
once to twice length of spore, in the caulicolous form usually much longer.
