ANNOTATED LIST OF SPECIES. 
ROCCELLACEAE. Orchilla Family. 
Rocella sp. ORCHILLA. 
The native name of this lichen is “‘orchilla.”” It was formerly the source of a large 
and profitable industry in the vicinity of Magdalena Bay, on the west coast of the 
Peninsula. It was shipped to England, where from the raw material fast dyes of 
several colors were extracted. When cheaper aniline dyes came into general use, 
however, the business became unprofitable. A recent demand for vegetable dyes 
may result in a revival of the industry. The plant seems to be confined mainly to 
a narrow strip of shore line, extending from near Magdalena Bay north for about 150 
miles, Orchilla grows in thick drooping, mosslike fringes along the branches of desert 
shrubs and trees near the coast. 
PINACEAE. Pine Family. 
Abies concolor (Gord.) Parry. WHITE FIR. 
Occurs rather sparingly on the cooler slopes above 2,250 meters in the San Pedro 
Martir Mountains. Collected at Vallecitos, July 15. 
Cupressus guadalupensis S. Wats.(?). GUADALUPE CYPRESS. 
A single cypress tree was found by us in a notch at about 2,700 meters altitude 
on the crest of the San Pedro Martir Mountains several miles east of Vallecitos, July 
15, and from it a branch bearing ripe cones was collected. From near the spot, which 
was reached on horseback, we had a splendid view of Santa Catalina Peak, the high- 
est of the San Pedro Martir Mountains, across a canyon to the southeast, and at our 
fect the east slope of the range broke away abruptly to the desert over 2,100 meters 
below. 
In the absence of specimens for comparison we assume ours to be the same as a 
species collected in the San Pedro Martir Mountains by Townsend and Anthony, 
regarded by Dr. C. 8. Sargent as somewhat different from the type of guadalupensis, 
but not separable from it.! | It seems very unlike C, goveniana, a widely ranging 
species, which approaches the Lower California boundary, and may prove to differ 
from guadalupensis, which grows abundantly at lower elevations on the more humid, 
fog-enshrouded slopes of Guadalupe Island. 
Juniperus californica Carr. CALIFORNIA JUNIPER. CEDRO. 
Abundant over many slopes along our route, beginning at about 450 meters alti- 
tude a few miles east of Ensenada, thence up through San Rafael Valley to the sum- 
mit of the Sierra del Pinal. It was also noted near El Alamo and in Trinidad V. alley, 
and farther south at 990 meters along the road from Rancho Santo Tomés to San 
Antonio, on the west slope of the San Pedro Martir Mountains. <A specimen in fruit 
was collected east of Ensenada, May 31. Brandegee records the species as far south 
on the peninsula as Agua Dulce. 
Specimens in the U. S. National Herbarium taken on Cedros Island by Dr. Edward 
Palmer and by A. W. Anthony, determined as Juniperus cedrosiana Kellogg,
