8. Ravenelia humphreyana P. Henn. 
On Poinciana pulcherrima L. 
Gualan (alt. 122 m. 400 ft.) Dept. Zacapa, Guatemala, Central 
America. Dec. 27, 1905. 
W. A. Kellerman, No. 5727. 
The host was determined by R. F. Griggs and the fungus by J. C. 
Arthur. The host is a common plant in many parts of Guatemala and 
it was found usually to be abundantly affected, though no effect on the 
vitality or vigor of the host could be detected. 
9. Ravenelia spinulosa Diet, et Holw. 
On Cassia biflora L. 
Gualan (alt. 122 m., 400 ft.), Depart. Zacapa, Guatemala, Central 
America. Dec. 30, 1905. 
W. A. Kellerman, No. 5441. 
The host was determined by J. M. Greenman and the fungus by J. 
C. Arthur. This Cassia is common and very abundant at Gualan and 
many other places in Guatemala; scarcely a plant was found uninfected 
by the Ravenelia which however did not appreciably distort the host or 
check its growth. 
10. Ustilago panici=leucophaei Bref. 
On Panicum leucophaeum H.B.K. 
Zacapa (alt. 137 m., 457 ft.) Depart. Zacapa, Guatemala, Central 
America. Jan. 25, 1905. 
W. A. Kellerman, No. 4301. 
The identification was made by Dr. G. P. Clinton. The smut was 
very abundant at this locality, infecting most of the plants found on the 
alluvial bottom where the material was obtained. The smut was seen 
also in abundance on the Pacific side of the country near Lake Amatitlan, 
alt. 1200 m. (3950 ft.). It has been reported from Mexico and from 
Cuba and Jamaica. Ustilago insularis P. Henn. regarded by Dr. G. P. 
Clinton as the same species, is from Rio de Janeiro, Brazil.
