GOLDMAN—PLANT RECORDS OF LOWER CALIFORNIA. 331 
1,200 to 1,680 meters. It is associated here in the Upper Sonoran Zone with a num- 
ber of other plants which are isolated by hundreds of miles of desert from their con- 
geners to the northward. It is rather common, especially along streams or about 
springs, growing as a shrub 3 to 6 meters high. A specimen in fruit was collected at 
about 1,350 meters near El Satiz on the trail from Miraflores to La Laguna. Brandegee 
records it from the Cape District as follows: Sierra de la Laguna, flowering in January ; 
Sierra de San Francisquito, fruit in October. 
Rosa californica Schlecht. & Cham. CALIFORNIA ROSE. 
Common in or along the borders of wet meadows in the Transition Zone along the 
western side of the San Pedro MArtir Mountains. Specimens in flower were taken 
at La Grulla, July 20. 
Rosa minutifolia Engelm. SMALL-LEAVED ROSE. 
Abundant in the lower part of the Upper Sonoran Zone, near San Quintin, where 
it is found along dry, stony arroyos among the lower hills and up over gravelly mesas 
to at least 300 meters altitude. It was also noted along the road from San Quintin 
north as far as San Telmo. It is a peculiar little species, 1 to 1.5 meters high, in 
places forming dense thickets, from which almost all other shrubs are excluded. 
Although the regular flowering season had passed, a few plants were still blooming 
when our collection was made near San Quintin, August 2. Of this rose and its 
limited known distribution Brandegee says: ‘“‘Abundant near the coast from north 
of Ensenada to below El Rosario. It extends into the interior a dozen or more miles 
from the Pacific slope. In some localities most of the bushes produce white flowers.” : 
Rubus sp. 
An unidentified Rubus is rather common in the oak forest on the upper slopes of 
the Sierra de la Laguna. It was collected in flower at 1,650 meters, in the Upper 
Sonoran Zone, January 27. 
Sericotheca dumosa (Nutt.) Rydb. 
In the upper part of the Transition Zone in the San Pedro Martir Mountains this 
shrub is fairly abundant. It forms clumps in the pine forest where other under- 
growth is scanty and is often associated with other shrubs on more open slopes, espe- 
cially among rocks near the tops of hills. A flowering specimen was collected at 2,400 
meters altitude near Vallecitos, July 15. 
AMYGDALACEAE. Almond Family. 
Emplectocladus fasciculatus Torr. 
This small almond, forming a shrub 1.8 to 2.5 meters high, was found near the 
western end of Trinidad Valley. It occurs here on rather dry slopes at about 780 
meters altitude, where the greater part of the vegetation is assignable to the Upper 
Sonoran Zone. The species has been recorded from southern California eastward to 
Utah, but apparently has not been taken before in Lower California. The genus to 
which it belongs is credited with representing the nearest approach in the American 
flora to the old genus Amygdalus, the almond of the Old World. A specimen bear- 
ing immature fruit was collected June 16. 
Prunus ilicifolia (Nutt.) Walp. HOLLY-LEAVED CHERRY. ISLAY. 
In Lower California this cherry is well known locally as ‘“‘isl4y.”” It is abundant 
in places in the Upper Sonoran Zone, from near the coast at Ensenada up to the tops 
of the Sierra del Pinal and at least as high as 1,500 meters on the west slope of the 
San Pedro Martir Mountains. It grows here as a shrub 1.8 to 3.5 meters high. The 
large, well-flavored fruit is gathered to some extent by the people at La Huerta and
