record accompanying one is simply: “ California, Rev. A. Fitch,’ 
while the other was collected by Dr. Parry when on the Mexican 
Boundary Survey, “between 32° and 36° N. Lat., and 114°-121° 
W. Long.” 
Professor Trelease referred with some doubt, both the original 
specimens of Mr. Nuttall and the later ones from California to his 
Oxalis corniculata var. (?) macrantha,* which. position, in the light 
of recent material and our present knowledge of geographic dis- 
tribution, cannot be maintained. The species is beautifully dis- 
tinct, and in addition to other characters, the pod is diagnostic, a 
Mr. Nuttall intimates,} differing from that of all other relatives 1n 
its short conic form. As descriptions of the plant are not easy of 
access I append the following:

D’Urv. 1826. 
Perennial by a slender horizontal or creeping woody rootstock, 
caulescent, low and bushy or much elongated, somewhat pilose of 
sparingly villous. Stems ascending or decumbent, .5—4 dm. long, 
simple or nearly so; leaves palmately 3-foliolate, 2-3 cm. broad, us- 
ually glabrate except the ciliate edge; petioles slender, 3-8 cm. 
long; stipules obsolete, or a narrow dilation; leaflets broader than 
long, sharply notched, the lobes usually unequal, ciliate; peduncles 
usually surpassing the leaves; pedicels forming umbellate cymes, 
commonly 2, subtended by linear-subulate bracts; flowers usually 
bright yellow, about 2 cm. broad; sepals oblong or oblong-lan- 
ceolate, 4-5 mm. long, obtuse, villous, erect or ascending; Pe 
obovate, 12-15 mm. long, undulate; filaments pilose; capsule 
conic, 8-11 mm. long, about twice as long as the. sepals, usually 
pubescent; seed oval in outline, nearly 2.5 mm. long, its tubercles 
almost united into continuous transverse ridges.

The second species described by Mr. Nuttall in this connection, 
under the name Oxalis pilosa is just as worthy of specific rank as 
Oxalis Suksdorfii. It is apparently rarer; however the scarcity of 
it in our herbaria may be due to the fact that*some collectors are 
inclined to pass by apparently well-known species in the - 
field. The history of this species is shorter than that of Oxalts 
eaenets ee
