which is thickened and coronate, gradually becoming lighter to¬ 
wards the pedicel, elongated-clavate, 16-20 x 84-112/a, fragile at 
base; pedicel very short, hyaline, fragile. 
On Trisetum virletii Fourn. Type collected by Dr. C. A. 
Purpus, Ixtaccihuatl, Mexico, 1903, altitude 7-8000 ft. 
Somewhat resembling Puccinia rhamni but at once distin¬ 
guished from it or any related species by the extremely long 
narrow teleutospores.

liebmannii Hack. No. 227, Dr. E. Palmer, Mexico, without 
further data. 
The material here referred was at first taken for a good 
new species. I am however indebted to Mr. E. W. D. Holway 
for data regarding the type which he has examined. The ure- 
dospores in the description are immature teleutospores. The 
following characters are drawn from the above specimens:— 
Sori hypophyllous, linear to oblong or oval, J-^xJ-i mm., 
dark brown, thickly scattered but seldom confluent, tardily naked, 
giving the surrounding epidermis a light reddish tinge; uredo- 
spores globose or subglobose, 22-29/A, light yellowish, echinulate, 
wall medium; teleutospores dark brown, globose to subglobose, 
22-31/A; wall thick (up to 5 /a) smooth; pedicel hyaline, flexuous, 
equaling or slightly longer than the spore, 2-6/a wide, often 
forming a prominent rounded enlargement at the base of the 
spore or gradually tapering to the end. 
But very few perfect sori can be found, the larger part of 
them being thoroughly infested with Darluca filum (Biv.) Cast., 
so that no spores or only fragmentary or immature ones remain 
in the sorus. This seems to be the case with a large number of 
tropical and subtropical grass rusts examined recently. In 
many of them so infected careful search fails to reveal any¬ 
thing more than a few uredospores, and they often in very 
poor condition. But for this parasite either a large number of 
additional grass hosts for some species of rust or else several new 
species of rusts might be easily determined.
