ularly scattered, short, deeply and rather coarsely split and 
much recurved; spores subglobose or elliptical (vertical diame- 
ter shorter), epispore thin, apparently smooth, contents finely 
granular, 15-18 by 18-20 »; spermagonia clustered above in 
the centre of the definite spots, otherwise sparsely scattered on 
both sides of leaf.

44. pteles, B.& C. 
Mostly hypophyllous. Spots distinct, yellow, thickened; 
ecidia irregularly clustered, cylindrical, rather long, becoming 
numerously and deeply split and much recurved; spores sub- 
globose or elliptical, large, conspicuously tuberculate, 21-25 by 
24-30 »; spermagonia not found. 
Spots pallid, in a hollow on the under side of the leaves; pseudo- 
podia crowded, short, radiated.—Berkeley, Grev., Vol. IIT, p. 61.

There is scarcely any doubt’ but that the plant described 
above is the .2eidinm ptelew of Berkeley and Curtis, though the

not be made out. 
4. onobrychidis, Burrill. 
Hypophyllous. Spots distinct or confluent, somewhat ef- 
fused, yellowish brown; ecidia subcircinate, crowded, short, 
border abruptly recurved, rather coarsely dissected; spores sub- 
globose or elliptical, epispore rather thin, studded with low, 
obtuse tubercles, sometimes united in ridges, 19-24 »; sperm- 
agonia clustered in the center of spots mostly on the upper 
surface, minute, reddish brown.
