Uredo Caricis, Schum. (Enum. Plant. Saell. II. [1803], 
p- 281), Puccinia caricis, Rebent. Fl. Neom. [1804], P. cari- 
cina, DC. (FI. Frane. VI. [1815], p. 60). 
On Dulichium spathaceum the uredospores are smaller and 
often elliptical to oblong, 12-15 by 15-21 «; the teleutospores 
are variable, more often truncate. 
P. obtecta, Peck. 
II., III. Amphigenous. Sori scattered or irregularly clus- 
tered, often crowded, oblong or more or less circular, long cov- 
ered by the epidermis, which at length becomes simply cracked 
or raggedly torn; uredospores elliptical or obovate-oblong, wall 
rather thick, minutely echinulate, pedicel rather persistent, 
15-20 by 21-30 »; teleutospores elliptical, somewhat constrict- 
ed, apex thickened, obtusely rounded or variously produced and 
pointed, usually narrowed below, often without septum, smooth, 
18-20 by 45-60 »; pedicel short, not usually more than half 
the length of the spore, deeply tinted. 
On Scirpus validus: McLean, July; Fulton, coll. J. Wolf. 
P. angustata, Peck. 
II., II. Hypogenous. Sori oblong or linear, often arranged 
in long parallel rows or confluent in long lines, blackish, the 
remains of the ruptured epidermis persistent; uredospores sub- 
globose to elliptical, thin walled, sharply echinulate, 16-21 by 
21-80 »; teleutospores narrow, clavate or elongate-parallel, 
somewhat constricted, apex much thickened, often beak-like, 
narrowed below to and with the pedicel, 15-21 by 45-60 p; 
pedicel colored, less than one half to once the length of the 
spore.
