A:cidium Nympheoides D.C. Epiphyllous, cups arranged without

The Puccinia was found floating down the river Ouse at King’s 
Lynn on 17th November, 1877, the host plant Scirpus lacustris 
having been cut out of some of its tributaries. It was not until 1894 
that the teleutospores were found in situ at Earith in Bedfordshire. 
A visit the following year instantly revealed the A®cidium in pro- 
fusion.

A&cidium Anchuse. 
Uredospores Sori 1-1°5 mm. long scarcely I mm. wide scattered, 
not confluent epiphyllous brown ; spores globose or shortly elliptical, 
echinulate, yellowish 20-30 py. 
Teleutospores Sori, covered by the epidermis, more or less scattered, 
forming more or less scattered black lines upon the under side (seldom 
on the upper) of the leaves. Each spore-group formed of numerous 
lines, each of which is surrounded by a crown of brown, curved, over- 
arching paraphyses. Spores with short pedicels, mostly elongate 
clavate unsymmetrical. Spores 40-50 u long, the breadth of the lower 
cell 12-15 p, of the upper 14-20 uw; spores germinating in autumn. 
The promycelium is colourless. 
Aicidiospores on Lycopsis arvensis in autumn. 
T eleutospores on wheat, rye. 
Eriksson and Henning record it on Bromus arvensis and molhs. 
The teleutospores are with great difficulty distinguished from those 
of P. glumarum, but the uredospores are totally different, the sori of
