Uromyces scillarum, Wint., Plowr., Ured., p. 141. 
Teleutospores. Sori on both surfaces of the leaf, minute, 
rounded or oblong, usually on pale spots, more or less 
crowded, often in rings, for a long time covered by the 
epidermis, then powdery, dusky brown ; spores globose, 
ovate or oblong, tip generally rounded, not thickened, 
smooth, or with a few faint lines running from tip to base, 
these sometimes run into each other, brown, epispore thin, 
18—32 X 14—22 p, pedicel about as long as the spore, 
slender, generally falling early.

Puccinia scillarum, Baxt. 
Trichohasis scillarum. Berk. 
Uromyces concentricus, Lev. 
On Scilia hifolia and S. nutans. 
Distinguished by the very thin wall of the spore, i—1.5 p, 
and by the fine, sometimes anastomosing lines, running 
the length of the spore. 
JUNCACEAE 
Uromyces junci, Tub, Plowr., Ured., p. 132. 
Pycnidia. Generally on the upper surface of the leaves. 
Aecidia. On the under surface of the leaves, on pur¬ 
plish spots bounded by a yellowish margin, or altogether 
yellowish, more or less crowded, sometimes in circles, yel¬ 
lowish-white, edge recurved and torn ; spores angularly 
globose, minutely warted, orange, 15—23 p. 
Uredospores. Sori on brown or yellowish long spots, 
minute, scattered, rounded or elongated, bordered by the 
torn epidermis, brown, powdery; spores subglobose or 
elliptical, finely warted, yellowish-brown, 17—28 x 16—22 
p, 2 equatorial germ-pores. 
Teleuto spores. Sori scattered, or in round or oblong 
groups, sometimes growing into each other and forming 
larger sori, bounded by the torn epidermis, blackish ; spores 
usually elliptical or pear-shaped, tip rounded, or sometimes 
slightly narrowed, very much thickened, base narrowed, 
smooth, deep brown, 20—^42 x 12—20 p, pedicel long,
