14 T. S. Brandegee: Plantae novae Californicae. 
capitate 6—10-flowered clusters near the ends of the branches, surrounded 
by spinulose-awned, tomentose bracts, the outer bracts broady ovate and 
spinulose-toothed, the inner becoming linear-lanceolate: calyx tomentose, 
1 cm long, the upper lip tipped with a spine, and near its base are two 
smaller spines representing lobes; lower lip of two linear-lanceolate lobes 
3 mm long, spinulose-awned: corolla nearly twice as long as the calyx, 
ochroleucous, slightly and gradually ampliated; upper lip 3 mm long, 
with two pointed lobes; lower lip slightly longer, 3-lobed, the middie 
lobe broadest and longest and irregularly fimbriate: anther of the lower 
fork of the connective half as long as the upper and polleniferous. 
This species has characters both of $ Echinosphace and $ Pycnosphace, 
but is very unlike S. carduacea and S. Columbariae of these sections. 
California: It was collected by H. M. Hall and L. A. Greata in 
Cañon Springs wash, about four miles northeast of Dos Palmas, Riverside 
County, California. No. 5848, H. M. Hall. 
4. Tetracoccus Hallii T. S. Brandegee, |. c., p. 229. 
A rigidly branched shrub of gray appearance, 2 m high, the smaller 
branches often spinescent, dioecious: leaves nerveless, in fascicles of 3—8 
covering the branches, obovate, attenuate at base, sparingly short-hirsute, 
4 mm long, 2—3 mm wide: staminate flowers 4—5 from the leaf, bearing 
nodes on pedicels 5 mm long: petals none; sepals 6, minute, the alter- 
nate ones reddish-colored: stamens 4—6, surrounding a central irregularly 
lobed disk, 2 mm long: pistillate flowers nearly sessile; petals none; 
sepals similar to those of the staminate flower; ovary usually 3-celled, 
cells 2-ovuled; styles 3—4, nearly distinct, recurved; immature capsule 
pubescent, 7 mm wide. No mature fruit seen. 
California: Collected by H. M. Hall and L. A. Greata at “Chuck- 
walla Bench, midway between Cañon Springs and Chuckwalla Spring, 
Colorado Desert, Riverside County, California. It grows both on the 
mesa and along a small wash, but was not at all common.” No. 5865, 
H. M. Hall. 
The genus Tetracoccus has hitherto consisted of a single species, based 
on specimens collected by Dr. Parry and C. R. Orcutt, near Santo Thomas, 
northern Lower California. Since then it has been collected by D. Cleve- 
land, eight miles north of Table Mountain, near the U. S. boundary line, 
and by C. R. Oreutt, near Temecula and the line of Riverside County. 
California. The new species is very distinct from the original one. 
5. Argithamnia Californica T. S. Brandegee, l. c., p. 230. 
Annual, monoecious, glabrous throughout, erect, branching, 15 cm 
high: leaves ovate-acuminate, attenuate at base into a petiole 5—7 mm 
long, serrate, 2—3 cm long, 10—12 mm wide: staminate flowers 2—4 in 
short axillary racemes about as long as the petioles, on pedicels 1 mm 
long; braets linear, white-margined; sepals linear-lanceolate: petals ovate, 
acuminate, 2,5 mm long; glands acuminate, 1 mm long: stamens in two 
verticels from the column: pistilate flower on a pedicel 1 mm long: 
sepals 4—5 mm long, linear-lanceolate, white-margined, glandular-denti-
