North American Salvia-Rusts 
157 
poles, but both are sometimes at the base near the pedicel, some¬ 
times at the apex, and occasional one at the base and one at the 
apex. The tubercles are deciduous, and a slight movement of 
the cover glass is sufficient to break them all off of the aecidio- 
spores, leaving them minutely roughed. They are found in this 
condition in old sori; so, too, are the teleutospores. 
The type specimen was found in the Herb, of the U. S. De¬ 
partment of Agriculture and was divided between the Herb, and 
Mr. Tracy. The Washington specimen seems to have disap¬ 
peared from the collection. I am indebted to Dr. Trelease for an 
opportunity to examine the Tracy specimen. It is a fragment of 
a leaf with a few sori, but there was one aecidium with a por¬ 
tion of the peridium attached, and there is no doubt about the 
uredospores described by the authors of the species being aecidio- 
spores. Those seen measured 24-28 x 26-38 /x, and possessed the 
same numerous minute germ-pores found in the Mexican speci¬ 
mens ; the tubercles had dropped off, leaving them “slightly 
roughened,” as described by the authors for their uredo. The 
teleutospores could not be examined thoroughly as the type was 
so small, but the three examined did not differ in any way from 
the Mexican specimens. The walls of the teleutospores are 2-3 ju, 
thick. 
This is a typical Diorchidium of the D. Woodii type, but 
there does not seem to be sufficient reason for separating it from 
Puccinia.

This species occurs on Salvia lanceolata only, so far as 
known. The specimens on Salvia Pitcheri Torr (S. azurea gran- 
diffora Benth.) which have been referred here are Puccinia fari-
