248 PUCCINIA 
AKcidia on Centaurea nigra, May and June; uredo- and 
teleutospores on Carex arenaria, July—April. Very rare; on 
the sea-shore, Hemsby, Norfolk. (Fig. 191.) 
" It has not been found anywhere else: but in all probability it could 
fairly be regarded as merely a well-marked biological race or mutation of 
P. Schoeleriana (q.v.). Plowright’s suggestion that it is identical with 
P. tenuistipes Rost. seems less likely, but it is closely allied to P. Caricis- 
montanae Fisch.

Monogr. i. 667. 
4icidiospores. Aicidia amphigenous or on the stems, seated 
on paler spots, scattered or in clusters, cup-shaped, whitish- 
yellow, with torn margin; spores delicately verruculose, pale- 
orange, 16—22 m. 
Uredospores. Sori on extensive pale spots, scattered, mi- 
nute, oblong or linear, reddish-brown; spores subglobose or 
ovate, irregular, very delicately echintlate, yellowish-brown, 
22—30 x 16—22 wu. “ 
Teleutospores. Sori oblong, $—1 mm. long, covered for a 
long time by the epidermis which at length splits, pulvinate, 
black; spores subclavate, rounded or truncate above, rarely 
hooded, thickened (up to 8,), gently constricted, tapering 
downwards, smooth, brown, 40—60 x 18—24 4; pedicels short, 
hyaline ; a few mesospores occasionally intermixed. 
Kcidia on Aster Tripolium, June, J uly; uredo- and teleu- 
tospores on Cares eatensa, August—June. Rare; Wells, 
Norfolk. f 
The life-history of this species was worked out by Plowright in 1888 ; 
it has hardly been found elsewhere except in Istria.
