156 New Species of Lower California Plants. [ZOE 
Iam under obligations to Dr. B. L. Robinson and Dr. J. M. 
Greenmann for their assistance in connection with many of the 
species and for comparisons made with types in the Gray Herba- 
rium, and also to Dr. J. N. Rose for comparisons with plants of 
the National Herbarium. 
Cardamine crenata. Sisymbrium crenatum Brandg. Proc. 
Cal, Acad. Ser. 2. III, 111, Plants collected by Dr. Purpus show 
that it differs from C. Pa/meri in having the lower leaves slightly 
pubescent, thinner in texture, ovate, cordate, acuminate, entire or 
slightly crenate-dentate; a’ much shorter pod and white flowers. 
The type specimen lacked the lower leaves and mature fruit. No. 
403, 458, Purpus. 
Spheralcea Margaritz. Annual, 6 dm. high, sparingly stel- 
late pubescent; leaves from round-subcordate to deltoid, obtuse or 
acuminate, sometimes 3-lobed, crenate or serrate, the larger 4 cm. 
long, 2-3 cm. wide, on petioles of the same length; inflorescence 
axillary and racemose at the upper part of the stem; corolla 1-2 
cm. wide, orange-scarlet; carpels 15-20, 1-ovuled, the scarious 
apex incurved so as to nearly meet the basal part, the thin scari- 
ous sides reticulated. 
This species is nearly related to S. Californica Rose, and S. 
Coultert Gray, from which it is easily separated by its axillary 
racemes two or three times longer than the leaves, which are of 
thinner texture, the scarious beaks of the carpels also more closely 
approach the basal part. .S. Calzfornica was collected by me in 
1902 in the Sierra de la Trinidad of the Cape Region, and in pre- 
vious years at Soledad, San Jorge and La Paz. Dr. Rose de- 
scribed it from specimens collected by Dr. Palmer at La Paz, and 
it is, as he writes, biennial or perennial. 
S. Margarite is a small annual growing on Santa Margarita 
Island of Magdalena Bay. Collected March 5, 1889. 
Abutilon fragile. Stems usually solitary, 1 m, high, branch- 
ed from the upper axils, hirsute-pubescent; leaves cordate, broadly 
ovate, long acuminate, crenate-serrate, sparingly stellate-pubes- 
cent below, nearly glabrous above; larger ones 10-12 cm. wide, 
12-14 cm. long, on petioles ro-14 cm. long; flowers 2-5 cm. wide, 
solitary in the axils, onpeduncles 5 cm. long that are jointed near
