206 ERYTHEA. 
Keidium Columbiense, E. & E. 
On leaves of Hieracium sp., British Columbia, July, 1893, 
Dr. J. Macoun. 
Hypophyllous, evenly scattered, cups shallow, open, 300 to 
400 y diam., margin dentate-toothed. Spermogonia scattered 
among the wecidia. Spores orange-yellow, globose, elliptical 
or subangular, smooth, 15 to 20 y in the longer diameter. 
Differs from Zc. Hieracii in its scattered mode of growth. 
Ecidium solidaginicolum, E. & E. 
On leaves of Solidago, Fort Collins, Colo., June, 1893, 
C. F. Baker, No. 135. 
Spots yellow, 3 to 5 mm. diam. Aicidia amphigenous, 
but mostly hypophyllous, innate, hemispherical, $ to 3 mm. 
diam., pierced at the apex with a small, round opening with a 
toothed margin, but never open as usual in most Aécidia. 
Spores globose, orange colored, 20 to 24 » diam. 
The structure of the cups is about the same as in Ac. 
hemisphericum, Pk. This is quite different from Ac. 
Solidiganis, Schu. 
CORRECTIONS IN NOMENCLATURE.—IIL. 
By Epwarp L. GREENE. 
The name Glossopetalon which the late Dr. A. Gray 
assigned to a western genus being only a homonym, I pro- 
pose that these shrubs shall bear the generic name 
FORSELLESIA. 
Glossopetalon, A. Gray, Pl. Wright. ii. 29 (1853), not of 
Schreber, Gen. i. 205 (1789). 
The new name is commemorative of James Henry Forselles, 
a swedish mining engineer and botanical writer of a half 
century ago. The species known are the following: 
1. F. spineseens (Gray 1. c. swb. Glossopetalo). 
2. F. Nevadensis (Gray, Proc. Am. Acad. xi. 73 (1875), 
sub Glossopetalo).
