 oblong, 0.5-1 mm. long, tardily dehiscent, urediniospores obovate or 

 narrowly ellipsoid, rather irregular, very large, 40-60 x 26-37 fi,

 pores obscure, 2 or sometimes 3, equatorial. 



"III. Telia chiefly hypophyllous, scattered or in longitudinal 

 series, oblong or linear, 0.5-1.5 mm. long, finally naked, pulvinate, 

 chocolate-brown, ruptured epidermis noticeable, teliospores clavate, 

 61-67 X 16-23 IX, usually rounded or obtuse above, narrowed below,

 other species of Malva. Described by McAlpine as follows : 



"III. TeleutO'Sori generally hypophyllous, brown to reddish- 

 brown or orange, but grayish when spores are germinating, compact, 

 round, pulvinate elongate on stems, scattered or crowded, seldom 

 confluent, at first covered by epidermis, soon naked. 



"Teleutospores fusiform, attenuated at both ends, apex some-

 thickening slight, smooth, yellowish-brown, rarely tricellular, 35-75 

 X 12-26 IX, average 50 x 17 /x; pedicels firm, long persistent, occa-

 Sydow as follows : 



"Pycnia disposed in small groups or scattered, honey- colored, seci-
