GOLDMAN—PLANT RECORDS OF LOWER CALIFORNIA. 851 
CACTACEAE. Cactus Family. 
Bergerocactus emoryi (Engelm.) Britt. & Rose. 
Patches of this serpentine cactus were seen on the shores of the Bay of San Quintin 
and along the beach south of Socorro on the road to Rosario. The range of the spe- 
cies is doubtless more or less continuous along the coast northward to the type locality 
at the international boundary and may include some of the islands. The stems vary 
in length from less than 20 to 150 or 175 cm. In some of the larger patches the stems 
grow more or less upright to a height of a meter or more and then turn downward and 
trail along the ground. 
Echinocactus falconeri Orcutt. PLATE 1238, A, 
The genus Echinocactus is represented in the desert regions nearly throughout the 
Peninsula, but the number of species and their respective ranges have not been fully 
determined. The present seems to be the most abundant and generally distributed 
species from at least as far north as latitude 28° to Cape San Lucas. It also has an 
extended range along the coast on the east side of the Gulf of California. As usual 
in the group to which it belongs, this species prefers stony places, especially the 
rock-covered slopes along the backbone of the Peninsula. It grows commonly 0.5 
to 1.2 meters high. Specimens were collected at Calmalli, San José del Cabo, and 
along the road from El Sacatén to Cape San Lucas. 
Echinocactus rectispinus (Hngelm.) Rose. 
This Echinocactus was collected by us at 1,020 meters altitude near Tinaja de 
Santana, 35 miles north of San Ignacio, October 4. It was growing to a height of 
1 to 1.5 meters among the rocks on a lava-covered mesa. A species which we took 
to be the same was abundant nearly all the way from the Santa Clara Mountains 
across the Peninsula to Santa Rosalia and northward at least to Calmalli. The type 
came from the vicinity of Mulegé, where it was collected by Gabb in 1867. Speci- 
mens referred to this cactus by Rose were collected by him at the head of Concepcién 
Bay, April 5, 1911. The species probably has an extended range in the Peninsula 
similar to that of E. falconert. 
Echinocactus fordii Orcutt. 
Rose refers to this species specimens collected by him on San Bartolomé Bay, 
March 13, 1911. 
Echinocactus chrysacanthus Orcutt. 
Specimens referred to this species by Rose were collected by him on Cedros Island, 
March 10, 1911. 
Echinocactus orcuttii Engelm.? 
A species found growing abundantly in San Matias Pass, at the north end of the San 
Pedro Martir Mountains, was photographed but not collected. It is probably orcuttii, 
which was based on material collected by Orcutt in Palm Valley, in the drainage of 
the Tijuana River. 
Echinocactus digueti Web. VIZNAGA. PLATE 123, B. 
While in the vicinity of the Cape we were told of the giant “viznaga’”’ of Cerralvo 
Island, and on our visit found this species quite common. It grows mainly, or is 
more abundant, along the rocky lower slopes of this mountainous island, often within a 
few feet of the water. One of the larger plants, which was chosen to be photographed 
and from which specimens were taken, measured 2.3 meters in height and 2 meters
