obpyriform, 3 to 4 em. long, 2 to 2.5 em. in diameter, bright-searlet and 
spiny: seeds angular, black, minutely pitted.—Type, Brandegee 243 in 
Herb. Brandegee. 
San Jose del Cabo, Lower California, and northward beyond San 
Ignacio; also on Carmen, Magdalena, and Santa Margarita Islands. 
Specimens examined: LOWER CALIFORNIA (Brandegee of 1889, San 
Joaquin, Magdalena Bay, Santa Margarita Island; also 243 of 1890, 
San Jose del Cabo; Palmer of 1890, Carmen Island). 
Mr. Brandegee says that the weak stems, no thicker than straws, are supported by 
bushes, and being of the same ashen hue as the bushes are concealed until in flower 
or fruit; and that the spines are so soft that the plant can be easily handled. The 
local name is “ pitahayita,” from the resemblance of the tlowers and fruits to those 
of gummosus, which is “ pitahaya.” 
53. Cereus cochal Orcutt, West Amer. Sci. vi, 29 (1889), 
Trunk stout, 3 dm. or more high before dividing into numerous stout 
branches, these repeatedly forking so as to give to the whole plant (grow- 
ing 12 to 80 dm. high) a graceful “candelabra shape”: ribs 4 to 8, 
obtuse, with wide shallow intervals and areole 2 to 2.5 em. apart: 
spines few, stout, straight and compressed, grayish or black: radials 
mostly 5, 15 to 20 mm. long; central solitary, more robust, laterally 
compressed, about 18 to 25 mm. long: flowers purplish-green, 2 to 3 
em. long: fruit the shape and size of an olive, not spiny, red (frequently 
grayish or yellowish-brown).—Type, in Herb. Orcutt. 
Lower California. 
Specimens examined: LOWER CALIFORNIA (Gabb 8 of 1867; Bran- 
degee of 1889, Comondu and San Pablo). 
This species was collected by Gabb in 1867, and is deseribed as a new species in 
Dr. Engelmann’s manuscript notes as C. gabbii. In 1886, however, Mr. Orcutt dis- 
covered it and published the name as above, being the Mexican and Indian name of 
the plant. Mr. Orcutt says that it is “abundant among the hills of Lower Cali- 
fornia, from Todos Santos Bay southward to the Rosario and San Fernando missions, 
or further.” The short woody trunk is said to be often 3 dm. in diameter, the long 
branches 6 to 20 cm. in diameter. 
54, Cereus eburneus (Link) Salm, Observ. Botan. 6 (1822). 
Cactus eburneus Link, Enum. ii, 22 (1822). 
Stem erect, simple, glaucous: ribs 7 to 10, obtuse and very glabrous, 
with ashy, naked, somewhat remote areole: spines subulate. rigid, 
ivory-white with black tip (purplish when young); radials 8 to 10, 
radiant, 8 to 10 mm. long, lowest smallest; central 1 (rarely 3 or 4), 18 
to 22 mm. long: flowers purplish: fruit unknown.—Type unknown. 
In the West Indies, and from San Luis Potosi southward through 
Mexico and Central America into Chile. Reported originally from 
Mexico in “ 22° lat., at altitude of 6-8000 ft.” 
Specimens examined: CuBA( Wright 2620): San Luis Poros (Parry 
& Palmer 276).
