ought not to be recognized as more than a variety, and as a recog- 
nizable though not necessarily permanent variation. 
What is true of E. purpureum Nutt. is equally true of three of 
SMALL’s segregates. They are based on no permanent characters, 
since in this genus color and size have been shown to vary with every 
change in the ecological factors. Two of these species, E. ochroleu- 
cum and E. orthocaulon, occur in the semi-arid portion of the 
Snake River basin and its tributaries. They may grow inter- 
mingled in the same district, as was the case in the superb specimens 
mentioned below. I therefore propose one varietal name to repre- 
sent the two as follows. 
ERIOGONUM OVALIFOLIUM celsum.—E. ochroleucum Small, Mem. 
N.Y. Bot. Gard. 1:123. 1900; E. orthocaulon Small, Bull. Torr. 
Club 33:53. 1906. 
MACBRIDE’S specimens, soon to be distributed under this varietal name, 
represent well the two colors, the oval to oblong leaves, and the tall scapes. 
New Plymouth, Idaho, May 21, 1910, nos. 85 and 86. 
ERIOGONUM OVALIFOLIUM vineum.—E. vineum Small, Bull. 
Torr. Club 25:45. 1808. 
Besides the wine-colored flowers, this is more noticeably tomentose, hence 
may be kept distinct from the preceding variety, though like that it merely 
represents the species in its maximum development. 
Stanleya rara, n. sp.—Inflorescence inordinately crowded, 
becoming 4 or more dm. long, the rachis only moderately stout: 
pedicels about 1o mm. long, in fruit 15-20 mm.: sepals yellow, 
linear, about 10 mm. long and 1 mm. or more wide: petals yellow, 
linear, narrower than the sepals and about three times as long; 
the claw longer than the sepals and but little narrower than the 
blade: anthers 3-4 mm. long, at length well exserted and more or 
less curved or coiled: ovary at full anthesis about 4 mm. long, some- 
what shorter than its stipe: pods at maturity filiform, 4-6 cm. 
long or possibly more, irregularly curved and spreading, on stipes 
nearly half as long and somewhat longer than the pedicels. 
This is a tentative description of a seemingly excellent species, and is 
described from only a fragment of the plant. This had been gathered for a 
bouquet by Mrs. Crourners, on a dry hillside, near Big Willow post-office, in 
Canyon Co., Idaho, about May 25, 1910, where it undoubtedly is indigenous.
