84 Muhlenbergia, Volume 9 
far from the Cape Arago lighthouse (in a region that is other- 
wise wholly Humid Transition), and represented by such spe- 
cies as: 
Sparganium simplex Huds. Viola pallens (Banks) Brainerd 
Eriophorum Chamissonis Mey. Cornus canadensis L. 
Calochortus Purdyi Eastw. Kalmia polifolia Waugh 
Alnus sitchensis (Regel) Sarg. Menziesia ferruginea Smith 
Darlingtonia californica Torr. Vaccinium ovalifolium Smith 
Drosera rotundifolia L. Trientalis arctica Fish. 
Sorbus sitchensis Roem. Senecio balsamitae Muhl. 
Following, is a list of the species collected, which have 
been placed in the National Herbarium, excepting a few, in the 
herbarinm of the New York Botanical Garden. The fact that 
the collection is as large and varied as it is, considering the late- 
ness of the season, is due in large measure to Dr. W. Hayden, 
of Marshfield, who kindly gave me much of his time, and per- 
sonally conducted me to some of the most interesting localities 
around Coos bay. Dr. Hayden has made a fairly complete col- 
lection of the plants of the region, many of which are cited in 
the following pages. 
My own collection for both years consists of 273 numbers, 
of which 210 are determined as to species, and, for the most 
part, listed here. Several grasses, sedges, Mimulus, Compositae 
and others, were determined for lack of time to make necessary 
comparisons at Washington, only as to genus. About forty 
numbers remain undetermined. As the writer cannot afford to 
spend further time upon the specimens, the list of species col- 
lected is presented in its present shape.
