GOLDMAN—PLANT RECORDS OF LOWER CALIFORNIA, 815 
and rather long, narrow, tapering crown. Thisis the pine which has commonly passed 
under the name murrayana, but late authors, such as Sudworth ! and Shaw ? apply 
the name contorta. 
GNETACEAE. Joint-fir Family. 
Ephedra californica S. Wats. 
Abundant near the Pacific coast at Ensenada, in San Rafael and Trinidad valleys, 
and up along sandy arroyos on the warmer slopes to about 1,560 meters on the west 
side of the Pinal and San Pedro Martir mountains, Over parts of the bottoms of San 
Rafael and Trinidad valleys it is the principal shrub. Specimens were obtained in 
flower at Ensenada, February 28, in fruit at La Huerta, June 2, and lacking flowers 
or fruit in Trinidad Valley, July 4. This species appears to occupy the Pacific slope 
of the San Pedro MArtir mountain region, while LZ. trifurca extends southward in the 
delta of the Colorado River. 
Ephedra trifurca Torr . 
Noted near Volcano Lake, along the basal slopes of the Cocopah mountains, and 
at other localities on the Colorado Desert. Plants of the genus were seen along much 
of our route through the desert as far south in the Peninsula as Rosarito, but as no speci- 
mens were obtained south of the San Pedro Martir mountain region the specific identity 
of the southern plants is uncertain. It seems probable, however, that trifurca extends 
for a considerable distance southward along the Gulf of California, leaving the moun- 
tain slopes, especially on the Pacific side, occupied by LE. californica. 
POACEAE. Grass Family. 
Conchrus palmeri Vasey. HUITSAPOL GORDO, 
The ‘‘huitsapol gordo,’’ as it is known, at least in the vicinity of Matancita, is a 
burgrass growing abundantly on sandy deserts nearly throughout the Peninsula. ‘The 
large, well armed burs of this species place it in the long list of desert plants to be 
avoided. Specimens with fully grown and ripening burs were taken at San lelipe 
on the Gulf of California, June 20, and with partly grown burs along the road from 
Santo Domingo to Matancita near the Pacific coast, November 15. 
PHOENICACEAE. Palm Family. 
Cocus nucifera L. CocoNUT PALM. 
The coconut palm has been introduced in a few places in the Cape District from 
La Paz southward. Small groves occurat La Paz, Cape San Lucas, and San José del 
Cabo. 
Erythea brandegeei Purpus. BRANDEGEE PALM, 
This is the tall species growing abundantly, especially in the canyons, on the mid- 
dle and upper slopes of the Sierra de la Laguna, south of La Paz, where it is often 
associated with Populus monticola. Brandegee states that the leaves generally fall 
away, leaving hard, smooth trunks which may reach a height of 37 meters, though 
less than 60 cm. in diameter at the base, and which, lacking the stiffness of other 
species of the genus, wave with the wind.
