PUCCINIA SEPTENTRIONALIS Juel. 
Since the previous note (Journ. Bot. vol. Lim, 1915) the 
uredospores of this species have been found on Ben Lui on 
Polygonum viviparum L. and the teleutospores on the same host 
on Meall nan Ptarmachan; the aecidium on Thalictrum alpinum 
L. has also been collected on Ben Voirlich (Loch Lomond). 
PUCCINIA DISPERSA Eriks. et Henn. 
Aecidia on Anchusa arvensis Bieb. near Kidderminster, 
August IgI2. 
Uredospores on Aira caespitosa L. Ballinluig, Perthshire, 
August I9I5. 
The aecidia on Anchusa have been shown to be connected 
with the form on rye (P. secalina). The specimens were found 
in proximity to a field of rye. 
The uredospore stage on Aira caespitosa has been recorded 
from a few localities in England by Grove (The British Rust 
Fungi, p. 265) but nothing appears to be known of its aecidial 
host or specialisation. Numerous capitate paraphyses are 
present among the uredospores. 
PucciniA MOLINIAE Tul. (?) 
Teleutospores on Molinia caerulea Moench. near Killin, Perth- 
shire, September 1919. 
Teleutospore sori amphigenous, black, elongated, up to 4 mm. 
long, pulvinate; spores ellipsoid, rounded at both ends, thick- 
ened above (up to 7p), very slightly constricted, smooth, 
yellow-brown, 32-44 x 19-29, mostly 36 x 25, pedicels 
hyaline, persistent up to 160 » long; mesospores present. 
A Puccima on Molinia caerulea was collected by Buchanan 
White in Perthshire, but has not been definitely connected with 
any aecidium; it appears however to agree in teleutospore 
characters with P. Moliniae Tul. 
The present specimens differ from those of Buchanan White 
principally in the greater thickness of the wall at the apex of 
the teleutospore. Rostrup (Bot. Tidsskrift, rv, 1874, pp. 10 and 
237) in Denmark has shown that Aecidium Orchidearum Desm. 
on Orchis latifolia is the aecidial stage of P. Moliniae and 
Schréter has found this aecidium growing along with P. Moliniae 
in Silesia. As a result of Rostrup’s work von Tavel (see Klebahn, 
Die wirtswechselnden Rostpilze, p. 97) has pointed out that 
P. Moliniae should be expected to occur in the plant association 
found in Switzerland described as ‘‘ Besenriedwiese”’ by Stebler 
and Schréter in which both Molinia caerulea and Orchis sp.
