138 PUCCINIA 
On Carlinavulgaris. July—October. Not common. (Fig. 89.) 
Distinguished from P. Cirsti, which it much resembles, by the larger 
uredospores, with very delicate hardly perceptible spines, and by the 
slightly smaller teleutospores which are more frequently narrowed below. 
But no cultures seem to haye been made to prove their distinctness.

‘Spermogones. Similar to those of P. Cirsit, 
Uredospores. Sori of two kinds; primary epiphyllous, on 
discoloured rounded or irregular spots, 
in concentric rings round the spermo- 
gones, sometimes confluent, 1—5 mm. 
broad, flat, surrounded by the cleft.

Fig. 90. P. Bardanae. Te- gregarious; spores globose to ellipsoid, 
aaa pe ae enn echinulate, pale-brown, 26—30 x 22— 
27 w, with three (rarely four) germ- 
pores. 
Teleutospores. Sori amphigenous, generally hypophyllous, 
without spots, scattered or in places densely gregarious, 
3—1 mm. diam., rounded, pulverulent, black-brown; spores 
ellipsoid, rounded at both ends, not thickened, gently constricted, 
delicately verruculose, dark-brown, 30—42 x 22—27 uw; pedicels 
hyaline, short. 
On Arctium Lappa. September, October. A doubtful 
native; I have seen no British specimens. Description after 
Sydow. (Fig. 90.) 
Distinguished from P. Cirsit by its larger teleutospores and by its two 
kinds of uredo-sori. Jacky demonstrated the distinctness of the two 
species by experimental cultures (Centralbl. f. Bakt. 2. ix. 796) ; also that 
P. Bardanae could not be transferred to Taraxacum. 
DisrRrisution: Europe only.
