apex and prolonged into a subhyaline conical papilla; pedicels 
slightly tinted, 80-11om long. 
The spores are sometimes quite irregular; sometimes 3-celled, 
with upper septum perpendicular or inclined, and the upper cell 
with two apiculi. Mesospores (unilocular spores) tolerably 
abundant, 30-40 X 18-22. 
Differs from P. Sofidaginis Pk. in its much smaller sori, nar- 
rower, more pointed spores and longer pedicels. 
PuCcCINIA LUDIBUNDA E & E. Proc. Acad. Nat. Sci. Phil. 1893: 
153. N. A. F. no, 3243. 
The description of this species is incomplete, no mention being 
made of the Uredo. This occurs in minute oblong pale orange- 
colored sori, about I mm. long, at first covered by the epidermis, 
but soon exposed, though inconspicuous. Uredospores obovate, 
16-22X12-14y, pale orange, faintly aciculate. Pedicels decidu- 
ous. The teleutosori also occur on both sides of the leaf. 
Arcipium Puioscis E, & E. 
On Phlox longifolia, near Lewiston, Idaho, Apr., 1896. (Heller, 
no. 2992.) 
Aecidia hypophyllous, evenly scattered, pustuliform at first, 
soon open and shallow cup-shaped with the margin coarsely 
lacerate-toothed ; spores globose or sub-elliptical or sub-angular, 
orange-yellow, smooth, 15-20» diam. 
This is not improbably the Aecidium of Puccinia plumbaria Pk. 
which is found on this same host. 
AECIDIUM ILICINUM E. & E. 
On living leaves of L/ex opaca, Nuttallburg, West Va., Apr. 20, 
1896. (L. W. Nuttall, no. 839). 
Spots amphigenous, purplish-black above, dirty-orange below, 
indefinite. Aecidia hypophyllous, mostly only one in the center 
of a spot, hemispherical or tuberculiform and closed at first, then 
laciniately dehiscent and margin coarsely toothed; aecidiospores 
irregular in shape, globose, ovate, elliptical or subangular, 18- 
22» in the longer diameter, epispore more or less wrinkled or 
tuberculate-roughened. 
AetcipiIum TissakE E. & E. 
On leaves atid stems of Zissa macrotheca, San Jacinto, Calif, 
March, 1896, (McClatchie, no. 1137.) 
Scattered or clustered ; aecidia small; short-cylindrical, margin
