40. Cereus maritimus Jones, sp. nov. 
Closely allied to polyacanthus, but with spines all reddisi-brown at 
first, becoming ashy, 4 or 5 erect-spreading terete or somewhat angular 
stout centrals 20 to 35 mm. long, 8 to 12 much smaller and slender but 
rigid radiately spreading very une qual radials (upper and laterals 8 to 10 
min., lower 4 to 6 mm.), and red flowers 3 to 4 em, long.—Type in Herb. 
Jones. 
Lower California. 
Specimens examined: LOWER Car. IFORNIA (Jones of 1882, Encenada; 
Oreutt of 1885, Todos Santos Bay; Brandegee of 1889, El Rosario). 
41. Cereus pacificus (Engelm.). 
Cereus pheniceus pacificus Engelm, West Amer. Sci. ii, 46 (1886). 
Oylindrical, 15 to 25 em. high, 5 to 6 em, in diameter, cespitose in 
dense cushions 30 to 60 cm. in diameter (50 to 100 stems in each): ribs 
10 to 12, obtuse, with shallow intervals: spines at first gray and more 
or less reddish. tinged, finally becoming ashy; radials 10 to 12, 5 to LO 
mm. long, no upper ones (or occasionally a minute spine); centr als 4 or 
5, widely diver gent, the lowest largest, 20 to 25 mm, long: flowers deep- 
red, the floriferous areola spiniferous: fruit spinose.—Type, Orcutt 
specimens in Herb. Mo. Bot. Gard. 
Lower California and adjacent islands. 
Specimens examined: LOWER CALIFORNIA (Orcutt of 18835 and 1886, 
Todos Santos Bay; Brandegee of 1889, Magdalena Island and Comondu 
Cliffs, of 1890, Sierra de la Laguna, of 1893, San Pedro Martio). 
But a few plants were found in bloom, January 26, 1883, by Mr. Orcutt, whose 
notes concerning them were first publishedin The Mest American Scientist,’ but since 
then abundant material has been collected by Mr. Brandegee. The spine we have 
called the uppermost central, by some might be considered an uppermost radial, the 
great irregularity of the spines in position making possible different interpret: tions.
