siderably broader and more nearly ellipsoid than in that species. 

 Uredinia associated with pycnia were found on a collection from 

 Porto Rico on Salvia coccinea, appearing like this species, but no 

 teliospores were present to make the determination certain. The 

 diagnoses for this and the following species were drawn up by 

 E.B. Mains. 



71. Puccinia diutina Mains & Holway sp. nov. (on Lamiaceae) 

 Salvia Pittieri Briq. (?), slopes of Volcan de Irazu above Car- 

 tago, Dec. 23, 1915, O, I, II, III, 290. 



Pycnia epiphyllous, few, noticeable, light brown, subepidermal, 

 globoid, 100-190 fx in diameter. 



Aecia hypophyllous, crowded on yellowish spots opposite the 

 pycnia ; peridium white, the margin erose ; peridial cells irregu- 

 larly rectangular in longitudinal section, 13-20 by 26-50 //,, abutted 

 or slightly overlapping, the outer wall 5—13 thick, striate, the 

 inner wall 1.5 /x, closely and finely verrucose; aeciospores ellipsoid 

 or globoid, 19-26 by 27-39//,; wa -U colorless, thick, 2.5-5/*, vei T 

 finely and closely verrucose. 



Uredinia amphigenous, scattered, round, small, 0.1-0.2 mm. in 

 diameter, early naked, pulverulent, dark cinnamon- or chestnut- 

 brown, the ruptured epidermis rather inconspicuous ; uredinio- 

 spores oblate-spheroid or globoid, 19-24 y, in diameter; wall dark 

 chestnut- or light cinnamon-brown above, 2 /x thick, becoming 

 rather abruptly colorless and less than 1 /x thick below, closely and 

 finely echinulate, the pores indistinct. 



Telia amphigenous, scattered, round, 0.1-0.2 mm. across, early 

 naked, somewhat pulverulent, blackish-brown, ruptured epidermis 

 rather inconspicuous ; teliospores broadly ellipsoid, 23-26 by 25- 

 33 fx, rounded at both ends, slightly or not constricted at septum ; 

 wall dark chestnut-brown, 2-3 /x thick, occasionally thickened up 

 to 5 y above, rather closely and coarsely verrucose ; pedicel color- 

 less, fragile, once to twice length of spore, sometimes attached 

 laterally. 



. The same species was also collected by Prof. Holway in 

 Mexico on Salvia scorodoniaefolia Poir., at Chapala, Sept. 24, 

 1899, II, iii, 3493, and at Oaxaca, Oct. 21, 1899, II, III, 3698. In 

 its teliospores it resembles P. badia somewhat, but in the other 

 two spore forms the species is markedly distinct.
