This species may occur on the same plants with Aecidium colum- 
biense (cf. 215) which is doubtless the aecial stage of some heteroecious 
rust not yet determined.. Sydow (I. c.) has described P. sejuncta 
based on such a mixture.

Puccinia Barbareae Cooke, Grevillea 8: 34. 1879. 
The type of P. Barbareae was described as on a “‘Cruciferous 
plant’’ from Oregon, Dr. Lyall 6z. The data on the type collection at 
the Kew Herbarium reads “Oregon Boundary Commission, Ft. Coville 
to Rocky Mts. 1861, Dr. Lyall 67.’ Since Ft. Coville is in north- 
eastern Washington there would seem to be little chance of this col- 
lection having been made within the state of Oregon. However, 
since it has been recorded from our limits both in the original descrip- 
tion and by Holway (N. Am. Ured. 1: 45. 1906) it is included here 
with the above explanation. The species undoubtedly does occur in 
eastern Oregon as the range includes all the surrounding states.

Evidently a common rust in western Oregon, otherwise known 
from North America from a few other collections made on the Pacific 
coast from California to Vancouver Island, B. C., and from a single 
locality along the eastern coast in Massachusetts. This species may 
be easily separated from P. Rhamnz (cf. 159) in the telial stage by the 
evenly thickened apices of the teliospores. The urediniospores of the 
two rusts are similar. Those of the present species are somewhat 
larger and globoid, 19-24 by 23-27 u, while in P. Rhamnzi they are 
globoid or broadly ellipsoid, 16-20 by 18-24 wu. 
The aecial connection is unknown. The rust has evidently been 
introduced from Europe and is able to maintain itself by over-wintering 
urediniospores.
