ZEcidiospores on Anchusa arvensis, Echium vulgare, September 
1 October. 
Teleutospores on Bromus mollis, Triticum vulgare, repens, 
tuum, Secale cereale, Hordeum vulgare, Holcus lanatus, mollis, 
ena sativa, elatior, from November to August. 
BIOLOGY.—Mesospores are not uncommonly mixed with the normal 
sutospores, especially when the fungus occurs on any of the genus 
rdeum = var. s¢mplex, Kornicke, and P. anxomala, Rost. The 
sospores are about 45 long. The teleutospores germinate in the 
umn of the year in which they are produced ; hence the zcidium is 
be found on Anchusa arvensis in September and October. The 
wwledge of this fact only came recently under my notice. In’ 1885, 
uid a bundle of wheat straw affected with P. rudigo-vera in my 
den, near some plants of Anchusa, in August, with the intention of 
ng some cultures in the following spring. In September, I found 
ny surprise the ecidium appearing on the Anchusa. This was the 
re remarkable, because I had never previously found the zcidium, 
1 the plants of Anchusa had been growing all the year in the garden 
fectly healthy. The uredospores are exceedingly abundant in 
ing, on wheat plants, in many parts of England, but the Puccinia, 
ike P. graminis, has very little prejudicial effect upon the crop. 
‘Isen also finds P. rudigo-vera germinates in autumn. It is very 
sible that more than one species is included under P. rudbigo-vera. 
Puccinia poarum. Nielsen. 
wdtospores—Spots yellow above, often surrounded by a violet 
margin, slightly thickened, concave. Pseudoperidia flat, with 
whitish torn edges. Spores subglobose, finely echinulate, 
orange-yellow, 18-24 X 15-18 in diameter. 
edospores—Sori small, round or elliptical, orange. Spores 
spherical or elliptical, echinulate, yellow, 20-30 in diameter. 
Without paraphyses. 
eutospores—Sori small, black, persistent, usually circinating, 
covered by the epidermis. Spores elliptical or clavate, very 
variable, apex flattened or conically thickened, dark brown, 
35-45 X 18-254. Pedicels very short, persistent, brownish.
