II. Uredinia hypophyllous, scattered, sometimes crowded, orbicular, small, 0.1-0,2 mm. 

 across, early naked, pulverulent, cinnamon-brown, ruptured cuticle inconspicuous; parapb- 

 yses peripheral, cylindrical or slightly clavate, straight, not exceeding the spore-mass, 

 8-13 by 30-45 /i, the wall colorless, uniformly thin, 1 fi, smooth; urediniospores globoid, or 

 slightly depressed-globoid, 23-27// in diameter ; wall golden-brown, 2-2. 5fi, often noticeably 

 thinner in vicinity of the pores, rather densely and evenly verrucose-echinulate with points 

 2-3 fi apart, the pores 2, opposite and equatorial. 



III. Telia usually amphigenous, scattered, small, 0.1-0.5 mm. across, early naked, dark 

 chocolate-brown or blackish, ruptured cuticle inconspicuous ; teliospores ellipsoid, 28-33 by 

 39-42 /^, rounded at both ends, slightly or not constricted at the septum ; wall dark chocolate- 

 brown, usually dense, strongly and closely verrucose, thick, 5-7 ft, slightly thicker at the apex, 

 7-10//, with a small, lighter-colored umbo; pedicel colorless, once to once and half length 

 of spore, with 3 or 4 whorls of large, much branched appendages near the base.

II. Uredinia hypophyllous, scattered, often crowded, minute, roundish, 0.1 mm. or 



less across, early naked, chocolate-brown, ruptured cuticle not noticeable ; paraphyses 

 numerous, peripheral, united at the bases, terete, 5-6 by 55-67 /i, acuminate, slightly 

 incurved, often somewhat wavy, the wall firm, about 2/i thick, chestnut-brown, smooth; 

 urediniospores globoid, 26-34," in diameter; wall laminate, inner layer cin namon -brown , 

 2-2.5 ju thick, outer layer paler, gelatinous, swelling in water up to 3-4^, rather sparsely

and equatorial. 



III. Telia at first arising from the uredinia ; paraphyses similar to those in the 

 uredinia; teliospores broadly ellipsoid, 30-37 by 40-50^, slightly or not constricted at the 

 septum, rounded both above and below; wall cinnamon- to chestnut-brown, 4-6 /^ thick, 

 gelatinous layer inconspicuous, sparsely verrucose with blunt conical papillae ; pedicel nearly 

 colorless, one half to once length of spore, with one or two irregular whorls of small, 

 somewhat branched appendages near the base.

O. Pycnia unknown. 



II. Urediniospores intermixed with the teliospores, few seen, broadly ellipsoid or glo- 

 boid, 18-23 by 24-27/^; wall golden-brown, not noticeably laminate, moderately thick, 

 2.5-3 /i, sparsely and strongly verrucose, the pores 2, opposite and equatorial. 



III. Telia hypophyllous, minute, scattered or often crowded into seemingly pulvinate 

 groups 0.2-1 mm. across, early naked, blackish, ruptured cuticle not noticeable; paraph- 

 yses numerous, peripheral, united at the bases, terete, 9-10 by 55-64//, acuminate, some- 

 what incurved, the wall firm, about 2 // thick, dark chestnut-brown, smooth ; teliospores few 

 in a sorus, broadly ellipsoid, 24-27 by 32-39 /^ rounded at both ends, slightly constricted at 

 the septum; wall chocolate- brown, rather thick, 3.5-4.5^, gelatinous layer golden-yellow, 

 not conspicuous except at apex and sometimes at base where it produces an umbo-like 

 thickening 2-3 //, closely and rather coarsely verrucose ; pedicel pale amber-colored through-
