thickened opposite the pedicel, which is variously inserted, mostly 
laterally, often in line with the septum, and globosely inflated 
next the spores and about the same length, strongly verrucose- 
reticulate, 30-44 x 22-37/A; dark reddish brown. On Echinop- 
teris Lappula Juss., Guadalajara, Mexico, No. 5036 Sept. 25, 
1903. Tehuacan, Puebla, Mexico, No. 5338, Nov. 7, 1903. Col¬ 
lected by the writer. 
Closely allied to Puccinia insueta Wint., from which it varies 
in its entirely different uredospores and the much stronger reticu¬ 
lations of the teleutospores. 
PUCCINIA RUBRICANS Holway n. sp. 
Spots crimson, mostly circular, from 1-6 mm. in diameter, 
most leaves having a few large spots and numerous scattered 
small ones. Sori amphigenous, mostly hypophyllous, solitary, 
scattered, or circinate on the larger spots. 
II. Uredosori light brown; uredospores pale brown, globose, 
rarely ovate, strongly echinulate, spines 3-4/A apart, wall thick, 
4 - 6 /a, 36-44 x 32-36/A. 
III. Teleutosori following in the uredosori, black, teleutos¬ 
pores elliptical, ferruginous, strongly verrucose, 60-68 x 40-44/A, 
apex shortly acute, or rounded, slightly thickened, pedicel hyaline, 
up to 8o/a long.

Aecidium williamsi Ricker sp. nov.—Spots yellowish, 
somewhat thickened; peridia densely clustered, mostly hypophyl¬ 
lous, cylindrical or elliptical; spores pale yellow, subglobose, 19- 
26 /a, minutely verrucose; wall medium, 2 /a. 
On leaves and stems of Lithospermum angustifolium Mx., 
Brookings, S. D., T. A. Williams, June 22, 1893. Specimens 
are also in the herbaria of the U. S. National Museum and Dr. 
J. C. Arthur. 
This species is not related to Puccinia lithospermi E. & K., 
originally described on Lithospermum canescens; but which 
proves to be Evolvulus pilosus Nutt., the Aecidium of which is 
as yet undescribed, but which the author has recently had the 
opportunity of examining in the herbarium of Mr. M. A. Carle- 
ton of this Department.
