GOLDMAN—PLANT RECORDS OF LOWER CALIFORNIA. 333 
height of 6 to 9 meters. A specimen with immature pods was taken on the road from 
Tres Pachitas to Valle Flojo, December 25. This species is recorded by Brandegee 
from mountains near San José del Cabo and Todos Santos. 
Lysiloma candida T. 8. Brandeg. PALO BLANCO. Prate 113. 
This tree, well known to the people as “palo blanco,”’ ranges in suitable localities 
throughout the Peninsula south of about latitude 27° 30’, It was first met with by 
us when we descended from the high mesa on which Tinaja de Santana is situated 
into a deep canyon on the road to San Ignacio. A few trees only were seen near the 
bottom, but later the same day we crossed another canyon in which it grew in a fairly 
heavy belt along each side of the water course, being here the most prominent spe- 
cies. From this point southward to the Cape the palo blanco was noted in the hill 
country at frequent intervals. In the northern part of its range the tree grows only 
in a narrow belt along dry washes in canyon bottoms, where it is often the largest and 
most abundant species. It was not seen on the plains along the west coast, but in 
crossing the backbone of the Peninsula from Cerro Colorado to Rodriguez and in the 
Cape District south of La Paz we found it much more generally distributed over the 
rocky hill slopes than farther north. 
The palo blanco is, economically, one of the most important trees of the Peninsula. 
One of the leading industries of the Cape District is the gathering of the bark, which 
is used locally for tanning, from San Ignacio southward, and is shipped in considerable 
quantities, especially from the port of San José del Cabo. The trees grow from 15 
to 30 cm. in diameter and from their whitish bark present a striking appearance, 
The bark is taken off in strips and packed in sacks for transportation on the backs 
of burros to the coast. 
Specimens of the tree were collected by us near Tinaja de San Esteban, 25 miles 
north of San Ignacio, October 5, and 20 miles east of San Ignacio, October 19. At 
both localities the ripe pods were falling from the trees. In ripening the stout mar- 
ginal threads split away and often adhere to the branch for some time after the pod 
bearing the seeds has fallen. A specimen in the U. 8. National Herbarium was col- 
lected by Palmer on Carmen Island, November 1-7, 1890. 
Mimosa purpurascens Robinson. 
Specimens in flower and ripening fruit were taken on the road from Agua Colorada 
to Cerro Colorado, December 15. It grows asa shrub 2 to 3.5 meters high. Not noted 
in abundance. 
Mimosa xanti A. Gray. CELOSA. 
This mimosa, locally known as “celosa,’’ is abundant throughout much of the lower 
country in the Cape District south of La Paz, where it helps to make up many of the 
denser thickets. It grows asa shrub 1.2 to 3.5 meters in height. The strong recurved 
thorns seem always ready to tear the flesh or clothing, whence the name “celosa,’’ mean- 
ing in the Spanish language “jealous.” Specimens with flowersand ripe pods were taken 
along the road from El Cajén to El Sacatén, December 28, at Santa Anita and Cape 
San Lucas January 3-11, and at San José del Cabo, February 22. Brandegee records 
it as very abundant at San José del Cabo, Todos Santos, and on the Victoria Mountains. 
Pithecolobium dulce Benth. GUAMUCHIL, GUAMUCHLII. 
This species, a tree of wide distribution on the mainland of Mexico, is abundant 
at San José del Cabo and was noted along the road between Santa Anita and Mira- 
flores. Brandegee records it from Todos Santos, La Paz, and San José del Cabo. It 
ranges much farther north on the coastal plains in Sonora. The white pulp surround- 
ing the seeds is eaten by the people.
