ARTHUR: NEw SpEcIES OF UREDINEAE 231 
Puccinia adenostegiae sp. nov. 
III. Teleutosori caulinicolous, round or united into effused 
masses, early naked, cinnamon-brown, ruptured epidermis incon- 
spicuous ; teleutospores oblong, 15-22 x 45-67 y, slightly con- 
stricted at the middle, apex obtuse, acute or sometimes acuminate, 
much thickened, base scarcely narrowed, side walls thin, pedicel 
delicate, somewhat tinted, as long as the spore or shorter. 
On Adenostegia pilosa (A. Gray) Greene (Cordylanthus pilosus 
Gray), foothills near Stanford, Cal., Jan. 1, 1902 (LeRoy Abrams, 
comm. F. S. Earle). As many as three fourths of the spores 
in this collection, which was made in mid-winter, and therefore on 
dead’ stems, had germinated. The species appears to belong to 
the leptopuccinia group. 
Uredo panici sp. nov. 
Chiefly hypophyllous; sori oblong, intercostal, brownish 
yellow, early naked, ruptured epidermis inconspicuous ; spores 
oval or globoid, 24-28 x 26-37 y, wall.thin, golden yellow, closely 
and conspicuously echinulate, pores more than 4, scattered. 
On Panicum amarum Ell., Longboat Key, Fla., April 27, 1900 
(S.M. Tracy, no. 6598), on Hog Island, Fla., Nov. 26, 1901 (S. 
M. Tracy, no. 7292, comm. F.S. Earle). The latter collection, 
which is accompanied by flowers of the host, is taken as the type. 
This uredo from its general appearance undoubtedly belongs to 
some Puccinia or Uromyces, although not a teleutospore could be 
discovered. The spores are larger than in any North American 
Species inhabiting Panicum now known; the size of the spores, 
character of the surface, and arrangement of the pores, easily dis- 
tinguish it, 
-Uredo cephalanthi sp. nov. 
ay oo i mostly hypophyillous, small, irregularly bullate, distributed 
ng Sel order, pale, long covered by the epidermis ; spores small, 
rst pedicellate, obovate-globose, 16-20 x 20-26 4, wall thin, 
in ut 14, closely and minutely echinulate, pores obscure, seem- 
gly 4 and equatorial.
