276 puccinia 



ovate, yelloWj faintly echinulate, 20 — 25x16 — 22 fi: membrane 

 colourless. 



Teleutospores. Sori hypophyllous, minute, covered by the 

 epidermis, oblong or linear, rarely confluent, black; spore9 

 somewhal clavate, rounded, truncate or gently nan -owed above, 

 slightly thickened (about 5 /x), faintly constricted, narrowed 

 below, smooth, brown, darker upwards, 38 — 48x12 — 20/j,: 

 pedicels very short. 



. lv-idia on Aquilegia vulgaris, Lewes, Sussex ; Lake Win- 

 dermere; Wyre Forest, etc., May, June; uredo- and teleuto- 

 spores on leaves and sheaths of Agrostis alba, A. vulgaris, 

 August. Uncommon. The Puccinia should be looked for on 

 the grass near the place where the secidium was seen. 



The connection between the aecidium <>n Aquilegia and the Puccinia 

 on Agrostis was first demonstrated by Plowright (see Gard. Chron. 1890, 

 ii. 139, and 1891, i. 683) ; the fact has since been confirmed ami extended 

 to Aquilegia alpina. McAlpine's species seems to be rather different ; he 

 records numerous mesospores, and uredospores with as many as nine 

 -•in i -pi ires, circularly arranged, on one face. 



Distribution: Central and Western Europe, Siberia, India, 

 ainl ( '.) Australia.
