novae ab E. L. Greene et J. N. Rose descriptae. 167 
with a shallow elongated pit or hollow on the sides marking the form of 
the seed within. 
2. Wislizenia Californica Greene, |. c.. p. 130. 
Wislizenia refracta Greene, Fl. Fr. 247, not of Engelm. 
Stout, much branched, the branches elongated, sparingly leafy, copi- 
ously floriferous, minutely scaberulous in lines: leaflets commonly oval, 
obtuse or subtruncate, mucronulate, sometimes narrower and acute, sca- 
berulous along the midvein beneath: carpels short, usually obovoid rather 
than pyriform, the longitudinal lines or ribs coarse but low and not very 
salient, somewhat broken into an obscure reticulation at summit and there, 
as it were, angled by 4 or 5 coarse and low tubercles. 
Interior of California, in dry sandy soil from about Tulare north- 
ward to Sacramento; abundant about Lathrop; totally distinct from the 
Texan W. refracta. 
3. Wislizenia divaricata Greene, |. c., p. 131. 
Glabrous, very widely and loosely branched, the branches from strongly 
divergent to quite divaricate, stout, rigid, uncommonly naked-looking, the 
scattered foliage small for the plant and all but the proper cauline leaves 
unifoliolate, the leaflets cuneate-oblong, almost pungently acute, 1,5—2 cm 
long: racemes many and elongated: fruit 5 mm wide, the carpels elon- 
gated pyriform, being constricted just above the base, marked longitudi- 
nally by a prominent narrow reticulation rather than by crowded and 
unbroken lines, the summit crowned with a circle of about 5 low tubercles. 
Southern part of the Colorado Desert in San Diego County, Cali- 
fornia, collected only by C. R. Orcutt, June 23, 1888, at Bonego Springs; 
distributed to National Herbarium under no. 1492. 
4. Wislizenia pacalis Greene, |. c. p. 131. 
Wislizenia Palmeri Brandg., Proc. Calif. Acad. 2. ser. I.: 128 in part, 
not of Gray. 
Branches stout, often tortuous or flexuous, not quite glabrous, red- 
dotted or purplish: leaflets always 3, oblong, usually very obtuse or even 
retuse or emarginate, 2—3 cm long: racemes remarkably short, sessile: 
fruit short, only 3—4 mm wide; carpels mostly round-obovate, in some 
specimens longer and subpyriform, the prominent striae 5 only, ending 
in a more or less distinct low tubercle, the intervening spaces conspi- 
cuously reticulate. 
La Paz, Lower California, 1890. Edw. Palmer, his no. 88 as in 
U. S. Herb. the type; but collected earlier, namely in 1889 at San Juanico 
by Brandegee, and at the same place by Anthony in 1897. Also in 
1897 it was collected at La Paz by Mr. Rose, no. 1311 as in U. S. Herb.; 
but these specimens have longer and even acutish leaflets; but the pe- 
culiarly reticulate carpels are about the same in all and are far more like 
those of the Texan and original W. refracta than like those of W. Palmeri; 
and Mr. Rose found himself unable to refer them to either species; his 
label bearing, in his hand, nothing but the name of the genus.
