than Kellogg’s. He also cites the Bolander specimen first. More- 
over, in the Fl. of Cal. i. 418 (1876), having noticed the leafy- 
bracted heads of Kellogg’s plant he appended a note to that effect 
and suggested ecological conditions as a probable cause. Of 
course it is now well-known that the character of leafy bracts 
beneath the heads is constant and of specific value. Professor 
Jepson, Fl. W. Middle Cal. ed. 2, 423 (1911) has indicated the 
glabrous (in age) involucre as a means of distinguishing this species 
(C. crassicaule) from C. Andrewsii but the elongate upper leaves 
also furnish a means of separation. The former character distin- 
guishes it also from C. praeteriens, which it resembles in its elongate 
upper leaves but these have the broad ample lobes of the leaves of 
C. Andrewsii. The broadly ovate proper bracts resemble most 
those of C. quercetorum, so it is not very surprising that Dr. Gray 
referred (although doubtfully) Kellogg’s rather meager specimen 
to that species. 
In recognizing the genus Cirsium as distinct from Carduus I am 
following Bentham, Gray, Hoffmann, Petrak and many others. 
It is rather singular that the recognition of this genus has not come 
more readily in this country. It was accepted in Gray’s New 
Manual, however, and I feel it will be taken up generally as soon as 
it is realized that the weight of authority in the botanical world is 
for its recognition. I am taking this opportunity to transfer two 
beautiful species with which I am very familiar in the field. The 
first forms an important component of the midsummer flora of the 
Laramie Plains and the second is characteristic of wet saline flats 
at low altitudes in central and western southern Idaho. It is truly 
a magnificent plant growing often as high as five feet and coloring 
gorgeously, both as to stem and bracts, toward maturity. The 
cobwebby pubescence of the bracts glistening in the sun accen- 
tuates their beauty. In emphasizing the attractiveness of this 
species I have had in mind Cirsium foliosum (Hook.) DC. which it 
resembles too closely in the herbarium and from which it is mainly 
distinct by characters of habit and habitat. C. foliosum, however, 
is a comparatively low plant, smaller in all its parts and an inhabi- 
tant of non-saline grasslands. It is not uncommon, either, in 
Idaho but the collector would never confuse 7 win C. magnificum.
