GOLDMAN—PLANT RECORDS OF LOWER CALIFORNIA. 349 
from Matancita to La Paz, but was more common at low elevations south of La Paz. 
Specimens with ripe bolls were collected between Cerro Colorado and Rodriguez, 
December 16, and with ripe bollsand flowers between Tres Pachitas and Valle Flojo, 
December 25. It is a shrub 1.2:to 2.5 meters high of no known economic value. 
Recorded by Brandegee from Magdalena Island, San Gregorio, and San José del 
Cabo. 
Gossypium harknessii T. 8. Brandeg. HARKNESS COTTON, 
This wild cotton, forming dense patches 1.2 to 1.8 meters high, is very abundant 
on the basal slopes of hills on Margarita Island, where it was discovered by Brande- 
gee. Specimens with flowers and maturing bolls were collected November 29. 
Hibiscus coulteri Harv. 
The handsome flowers of this species were seen in a few fertile spots along the road 
through the lava beds from La Purisima to Comandt. It isa shrub 1.8 to 2.5 meters 
high. Specimens were taken in flower November 5. Brandegee records the species 
from San José del Cabo and La Paz. 
STERCULIACEAE. 
Fremontodendron californicum (Torr.) Coville. FREMONTIA. 
We observed this handsome shrub or small tree only in the Upper Sonoran Zone 
at San Matias Spring, where the extreme northern end of the San Pedro Martir Moun- 
tains slopes down into San Matias Pass. Flowering specimens were taken June 28. 
Melochia tomentosa L. 
The range of this tropical shrub includes the southern half of the Peninsula. It 
was rather common in places, mainly near water among the hills in the interior. It 
was taken in flower and immature fruit at Tinaja de San Esteban, 25 miles north of 
San Ignacio, October 5. Brandegee records the species as common everywhere in 
the Cape District south of La Paz, except in the mountains. 
FOUQUIERIACEAE. Ocotillo Family. 
Fouquieria splendens Engelm. OCOTILLO, 
Among the most abundant shrubs in the Peninsula are this and the following spe- 
cies of Fouquieria. The “ocotillo,”’ as I’. splendens is locally called, ranges in the 
Lower Sonoran Zone from southeastern California southward along the east side of 
the high mountains, spreading across the Peninsula sovth of the San Pedro Martir 
Mountains, and finally meeting and, for a short distance only, overlapping the range 
of F. peninsularis in the vicinity of Rosarito. It is rather partial to gravelly or rocky 
hillsides and ascends the eastern basal slopes of the San Pedro Martir Mountains to 
1,140 meters in San Matias Pass. Near the west coast it was first seen between Rosario 
and Las Cuevas. It was taken in flower at San Fernando, September 4. 
Fouquieria peninsularis Nash. PALO DE ADAN. PLATE 120. 
The “palo de Adan,”’ as this species is called by the people of the Cape District, 
was first noted near San Andrés. Here it occurs along with #. splendens, from which, 
however, it differs very noticeably in habit. That species ramifies from near the 
ground into comparatively few stout, straight stems. Fouquieria peninsularis is usually 
not so tall, the stems are more numerous and much more ramified, and the small 
branches are more slender.and crooked. It usually has a well-formed but short trunk. 
Southward from the vicinity of Rosarito, beyond which F. splendens was not noted,
