118 ARTHUR: NEW SPECIES OF UREDINEAE 
Puccinia gentilis sp. nov. 
II. Uredinia hypophyllous, scattered, round or elliptic, 0.3—-0.8 
mm. across, pulverulent, cinnamon-brown; urediniospores oblate- 
spheroid, 23-26 » broad by 19-24 u long, or globoid to obovoid, 
21-23 by 21-28; wall dark cinnamon-brown, 1.5-2 y thick, 
moderately and strongly echinulate, the pores 2 or 3, subequatorial 
or approximately equatorial. 
Ill. Telia hypophyllous, similar to the uredinia, becoming 
pulverulent, blackish-brown; teliospores broadly ellipsoid, 27-32 
y 35-45 mu, rounded above and below, not constricted at septum; 
wall chocolate-brown, thick, 3-5 wu, thickened over the germ-pore 
into a yellowish umbo, 7-10 p thick, moderately verrucose with 
markings uniting into short irregular lines giving a coarsely verru- 
cose appearance; pedicel colorless, with thin walls, 1 u or less, 
twice length of spore 
On Salvia aleansdne Rose, Oaxaca, Mexico, October 21, 1899, 
II, iii, EZ. W. D. Holway 3699; Salvia sp., Oaxaca, Mexico, October 
18, 1899, II, III, E. W. D. Holway 3666 (type). The species is in 
many respects similar to Puccinia mitrata Syd., but the uredinio- 
spores are larger and more prominently echinulate. 
Puccinia prospera sp. nov. 
II. Uredinia amphigenous, scattered, round, 0.2-0.8 mm. in 
diameter, pulverulent, cinnamon-brown; urediniospores oblate- 
spheroid, 25-30 broad by 20-234 long; wall cinnamon-brown, 
1.5 thick, moderately and rather strongly echinulate, the pores 
2 or 3, subequatorial. 
III. Telia hypophyllous, similar to the uredinia, pulverulent, 
chestnut-brown; teliospores broadly ellipsoid, 27-32 by 35-40un, 
rounded above and below, not constricted at septum; wall chest- 
nut-brown, rather thin, 1-2.5 4, thickened over the germ-pores, 
5-7 u, obscurely verrucose-rugose; pedicel colorless, fragile, once 
to once and half length of spore, thin-walled, fragile. 
On Salvia microphylla H. B. K., Toluca, Mexico, September 
17, 1898, Il, E. W. D. Holway 3136; Pachuca, Mexico, October 5, 
1899, II, III, E. W. D. Holway 3579 (type). Another species of 
the P. mitrata group, the teliospores being of the same size as those 
of that species, but with the thickness of wall and its markings 
like P. farinacea Long. The urediniospores also have the size of 
P. farinacea.
