teliospore is in the lower half of the cell, instead of in the usual position 
close to the septum.

The species occurs also in southern Mexico, and has not so far been 
found on more than the one species of host. The initial stages of the 
life cycle are unknown. 
The species was collected by Kellerman at Volcan de Atitlan, Dept. 
Solola, Feb. 16, 1906, 5438, and reported by Kern in Journ. Mycol.

161. Puccinia (?) degener Mains & Holway sp. nov. (on Lamiaceae). 
Salvia alhiflora Mart. & Gal. (?), road between Quezaltenango and 
Colomba, Feb. 4, 1917, II, 838. 
Uredinia hypophyllous, scattered or crowded in small groups, 
round, 0.1-0.3 mm. in diameter, early naked, pulverulent, cinnamon- 
brown, ruptured epidermis evident; urediniospores broadly obovoid- 
globoid, or somewhat flattened from above, 19-23 by 19-25 ^t; wall 
light cinnamon-brown, thin, 1-1.5/z, moderately and rather promi- 
nently echinulate, with one subequatorial pore, usually 5-7 from 
the hilum. 
Apparently distinct from all other known Salvia rusts in its single 
basal pore. Its general resemblance to the preceding group of species 
makes it seem safe to place the form under the genus Puccinia with no 
present knowledge of the teliospores.
