2. Puccinia Foyana n. sp.* (Fig. 78.) Ranunculaceae. 
0. Unknown. 
I. Aecidia amphigenous, chiefly hypophyllous, in crowded irregular 
groups, seated on somewhat inflated «pots up to 10 mm. diam., orange. 
Peridia cupulate, 0-5 mm. diam., ns erect, somewhat incurved, 
white, laciniate. Spores polygonal or “elliptical, 22-30 x 15-20 mmm. ; 
epispore hyaline, finely and densely verruculose, 1 mmm. thick, cell- 
contents vacuolate, orange. 
III. Teleutosori amphigenous, petiolicolous and .caulicolous, arranged 
in scattered оше up to 5 mm. diam., bullate, pulverulent, orbicular, 
0-25—0-5 , long covered, becoming exposed by the longitudinal 
fissuring of de манин. Spores elliptical, less commonly clavate, 
42-65 x 2 mmm.; apex acuminate, seldom rounded, crowned with 
a prominent hyaline papilla, slightly (6 mmm.) or not thickened, base 
rounded or bluntly attenuate; slightly or not constricted at the septum ; 
epispore smooth, bright chestnut- тысе 2-5-3 mmm. thick, cell-contents 
cel deciduous, hyaline, to 30 x 8mmm.; germ-pore of 
the upper cell apical, conspicuous, раш, basal pore immediately beneath 
the septum, conspicuous, papillate. 
X. Mesospores not uncommon, elliptical, 20-35 x 17-24 mmm

3. Puccinia namua n. sp. (Text-fig. 79, and Plate 2, fig. 7.) 
Umbelliferae. 
I. Aecidia amphigenous and caulicolous, crowded in scattered groups 
to 25 mm. — ite on slightly inflated, discoloured spots, orange. 
Peridia cupulate, 0 iam., 1 mm. , margins erect, not revolute, 
laciniate, white. Spates ‘polygonal or subglobose, 18-24 mmm. diam. ; ` 
epispore tinted yellow, densely and m inutely verruculose, 1-1-5 mmm. 
thick, cell-contents vacuolate, orange. 
I. Uredosori amphigenous, chiefly hypophyllous, and caulicolous, on 
leaves scattered, orbicular, up to 15mm. diam., seated on pallid- 
yellow spots; on stems linear, up to 3mm. long, seldom confluent ; 
orange-yellow, bullate, pulverulent, surrounded and partly covered by 
the ruptured epidermis. Spores elliptical, obovate, seldom  globose, 
18-30 x 16-22 mmm.; epispore tinted yellow, sparsely and moderately 
echinulate, 1-1-5mmm. thick, cell-contents granular, sulphur-yellow ; 
germ-pores 4, equatorial, obscure. 
III. Teleutosori similar to the uredosori but chestnut-brown. Spores 
subclavate or elliptical, 30-40 x 18-26mmm.; apex rounded, not 
thickened, base attenuate, lower cell narrower than the upper; slightly 
constricted at the septum; epispore coarsely warted, chestnut-brown, 
2-2-5 mmm. thick, compe granular;  pedicel persistent, hyaline, 
fragile, up to 25 x m.; germ-pore of the upper cell apical, con 
spicuous, basal pore ; гегин the septum, conspicuous.
