II. Uredinea chiefly hypophyllous, scattered, oval, or oblong, 

 0.1-0.5 mm. long, early naked, on some hosts rather tardily naked, 

 somewhat pulverulent, ruptured epidermis usually not conspicuous, 

 urediniospores globose, broadly ellipsoid or obovoid, 15-21 x 19-24 yu, 

 (rarely larger, up to 25 to 34 fx.) wall golden-brown or chestnut- 

 brown, 1.5-2 IX thick, moderately finely and evenly echinulate, the 

 pores 2-4, usually 3, equatorial (or sometimes) partly or wholly 

 (near the hilum). 



III. Telia chiefly hypophyllous, scattered, rounded or oblong, 

 0.1-0.2 mm. broad by 0.1-0.5 mm. long, sometimes appearing longer 

 when confluent end to end, early naked with ruptured epidermis not 

 conspicuous, pulvinate, blackish-brown, or on some hosts long, cov- 

 ered by the epidermis and greyish to black, teliospores broadly cla- 

 vate, 14-24 x 32-58 /*, roundish truncate, or rarely accuminate above, 

 slightly or not constricted at the septum, wall cinnamon or light 

 chestnut-brown, 1-1.5 [x thick, thick at the apex, 4-10 /a, smooth, pedi-

PucciNiA HELiANTHi Schw. — On Heliantlius annuus. Described 

 by McAlpine as follows : 



"O. Spermogonia honey-colored, in small clusters. Aecidia 

 crowded or orbicular, or arranged in broadly expanded, oblong 

 spots ; pseudoperidia cylindrical, plane, with white laciniate margins. 



"I. Aecidiospores orange red, ellipsoid to polygonal, finely echin- 

 ulate, 21-28 X 18-21 fjL. 



"II. Uredosori roundish, chestnut-brown, scattered or confluent, 

 pulverulent, often on yellow or pale green spots on upper surface of 

 leaf, but generally forming brown mass on under surface. 



"Uredospores subglobose, elliptic or obovate, golden yellow, 

 echinulate, epispore subhyaline, showing one germ pore on one face, 

 2]-24fi diam. Or 24-29 x 15-22 fi. 



"III. Teleutosori roundish, dark brown or black prominent, 

 scattered at first, but ultimately in clusters, confluent, dotting both 

 surfaces of leaf, but most prominent on under. 



"Teleutospores at first intermixed with uredospores, chestnut- 

 brown, oblong-elliptical or pear-shaped, smooth, but occasionally a
