s there are few or no morphological differences between these two 
ы (the aecidial stages not occurring here), I have thought it advisable 
to include them under the original name, as Arthur and Fromme (1920,

I. Aecidia ki gm c and on calices, seated on spots which may 
reach a diam. of 2mm., yellow. Регійіа low, fairly broad, mar, revo- 
lute, finely laciniate. " Aecidiospores polygonal, nicae or elliptical, 
20-31 x 15-22 mmm. ; epispore closely and finely verruculos 
II. Uredosori amphigenous, light ferruginous-brown, elliptical or linear, 
0:5-2 mm. long, rarely confluent, pulvinate, becoming pulverulent, sur- 
rounded by ruptured epidermis. Spores subglobose or elliptical, 22-30 x 
22-25 mmm.; epispore finely and closely echinulate, 1:5-2 mmm. thick, 
yellowish-brown, with 4—6 scattered germ-pores on one face 
III. Teleutsori amphigenous, chiefly hypophyllous, black, en or 
more frequently linear, when up to 3mm. long, long covered, divided 
compartments and entirely surrounded by dh slightly rete 
stout paraphyses, which are as a rule firmly agglutinated together. Spores 
elongate-oblong to clavate, 40-65 x 12-22 mmm. ; apex ci cer rounded, 
or bluntly acuminate, often oblique, thickened up to 5mmm., more deeply 
coloured than rest of spore, base attenuate, basal cell narrower, longer, 
and lighter in colour than upper; slightly constricted at septum ; epispore 
ames chestnut-brown, 2mmm. thick in upper, 1 mmm. thick in lower 
cell ; pedicel persistent, continuous with spore, coloured, stout, short, up 
to 91 X 7T mmm. ; germ-pore of upper cell apical, obscure, basal pore 
immediately below septum, obscure.

Wint. into three—P. glumarum, P. simplex, and P. dis sper in account 
of certain morphological differences, chiefly in the uredosori. Shortl 
afterwards Eriksson (1894, p. 292) showed by cultural experiments that 
P. glumarum and P. dispersa each consisted of five biological races.
