No distinct nredospore sori known, but a few uredospores 
rarely occur with the teleutospores. 
CARYOPHYLLACEAE 
Uromyces behenis, Unger, Plowr., Ured., p. 138. 
Aecidia. Generally on the under surface of the leaf, 
on spots of various sizes, clustered or sometimes solitary, 
tinged yellow, edge recurved and torn ; spores angularly 
globose, minutely warted, yellow, 15—21 p. 
Teleutospores. Sori generally on the under surface of the 
leaves, or on the stem, often mixed with the aecidia, scat; 
tered or in groups, covered for a long time by the greyish 
epidermis, minute, almost black; spores subglobose or 
ovate, tip rounded and much thickened, smooth, pale, 
brown, 25—40 X 17 — 27 p, pedicel persistent, thick, 
twice as long as the spore. 
Syn. Aecidium hehenis, D.C. 
On Silene injlata and 5 . mariiima. Europe generally. 
The host-plant is often much distorted. 
Uromyces sparsus. Lev., Plowr., Ured., p. 136. 
Uredospores. Sori on both sides of the leaves, or on the 
stem, scattered on pale spots, convex, for a long time 
covered by the epidermis, which cracks and shows the pale 
cinnamon, powdery mass of spores ; spores globose or ob¬ 
long, minutely echinulate, brownish, 18—-25 X 15—^22 p. 
Teleutospores. Sori resembling those of the uredo form 
in shape and size, but darker ; spores subglobose, ovate 
or oblong, frequently narrowed below, tip rounded, slightly 
thickened and darker, smooth, brown, 22 -—40 x 14-—24 p,

Aecidia. Sori occur on both surfaces of the leaves, on 
yellowish rounded or elongated spots, yellowish, edge re¬ 
curved and torn ; spores angularly globose, minutely warted 
tinged yellow, 15—25 p. 
Uredospores. Sori scattered or arranged in circles, on 
ooth surfaces of the leaves, surrounded by the torn epider- 
nis, powdery, cinnamon ; spores subglobose, elliptical or
