GOLDMAN—PLANT RECORDS OF LOWER CALIFORNIA. 829 
CRASSULACEAE. Orpine Family. 
Dudleya anthonyi Rose. PLATE 112. 
Found growing abundantly on the rocks along the shores of San Martin Island, 
where the type was collected by A. W. Anthony, July-October, 1896. The large 
size and light color of the leaves render the plants conspicuous in contrast with the 
dark-colored rock. 
HYDRANGEACEAE. Hydrangea Family. 
Philadelphia pumilus Rydb. 
A rather common species in the Transition Zone at Vallecitos in the San Pedro 
Martir Mountains. Tere, at 2,400 meters altitude, it grows as a shrub 1.2 to 1.8 
meters high on dry rocky slopes bordering open meadows. A species here assumed to 
be the same was recorded by Brandegee from these same mountains under the name 
P. serpyllifolius,! as also by Hall from the San Jacinto Mountains in southern Califor- 
nia.2 This name belongs to a different species found in western Texas and New 
Mexico. One of Hall’sspecimens subsequently became the type of P. pumilus. Our 
material, taken in flower July 15 at Vallecitos, agrees well with Rydberg’s descrip- 
tion, and it therefore seems probable that the species has a more or less continuous 
range in the Transition Zone from the mountains of southern California southward 
to the San Pedro Martir Range. 
GROSSULARIACEAE. Gooseberry Family. 
Grossularia quercetorum (Greene) Coville & Britton. GOOSEBERRY. 
Found growing rather sparingly at 810 meters on the nearly open plain in the bot- 
tom of San Rafael Valley, a few miles west of La Huerta, where specimens were col- 
lected June 2. It was also noted in Trinidad Valley, in San Matias Pass, and at 
1,080 meters elevation in ascending the dry northwestern slopes of the San Pedro 
Mértir Mountains, along the road from Trinidad Valley to Pozo Luciano. It grows 
as a shrub 1 to 1.5 meters high in the lower part of the Upper Sonoran Zone. 
Ribes indecorum Hastw. CURRANT. 
From the type locality near San Diego this currant ranges southward into Lower 
California. It was first noted by us at 840 meters elevation, growing on north slopes 
only, near La Huerta at the western base of the Sierra del Pinal. It grows as a shrub 
1.8 to 2.5 meters high. Specimens were collected June 2, when the plants were well 
laden with young fruit. A currant which we took to be this species was seen at 900 
meters near San Antonio, at the west base of the San Pedro Martir Mountains. 
Ribes brandegei HEastw. CURRANT. 
Known only from the upper slopes of the Sierra de la Laguna, where, like a num- 
ber of other Upper Sonoran species, it is isolated from its congeners by a wide desert 
interval. It occurs rather sparingly, mainly along water courses, from an elevation 
of about 1,380 meters to near the summit in the vicinity of La Laguna. It isaslender 
species, reaching a height of about 2.5 meters. A flowering specimen was collected 
January 26.
