In all these specimens the teleutospores _ in size and 
structure with Fuckel’s description as given by Saccardo. 
In all these the uredospore sori are distinctly Seine than those 
of the specimens recently collected. It seems that this difference 
in size does not depend on the age of the sorus, since some of the 
Scottish specimens were collected in June and some in October, 
and the German specimens in July. It is probable a two 
forms have been included under P. dutherdinthe as follow

It must not 5 iegntteis that P. borealis produces its uredo- 
spore and teleutospore stages on Anthoxanthuwm odoratum, and, 
almost indistinguishable from the specimens of P. Anthowantht 
from the British Museum which have been just described. 
P. borealis apparently only differs from form 1 in possessing

MELAMPSORA ALPINA Juel. 
Melampsora alpina occurred on Salix herbacea L. on Ben 
Lui in October, 1914, at about 2500 ft. Both ecelonored and 
teleutospores are present. 
The uredospore sori are small, scattered, rounded, amphigenous 
and orange yellow in colour; spores ellipsoidal or spherical, 
19-22 x 14-17 p, finely echinulate, contents orange yellow; 
paraphyses woinidanit capitate, thick walled, up to 88 » in length, - 
cee reel about the same size as the uredospores, wall up to 5 » in 
thickn 
The ‘eloutospore sori are amphigenous, rounded, mostly on the 
upper surface, those on the lower surface being usually ee 
and a to the tagpse wre Bes the upper surface, which are up 
to 8 n diameter, brownish black, covered by the epidennil: ; 
spores Pastensd< or staid“. at the apex, rounded and usually 
dimini —, in size towards the base, 26-50 x 9-14 p, wall thin, 
smooth, yellowish-brown. 
. alpina was discovered by Juel in Norway and Sweden, and 
has been subsequently recorded from Switzerland. It has been
