plants; becoming recurved; filaments rosy, stout at base anthers 
violet or purplish, shorter than the style which is white with 
white acute stigmas which connive, forming a conical body. 
Scales of the ovary triangular ovate, bearing wool and some- 
times bristles. Spines variable in number. 
The flower opens in the morning and remains expanded night 
and day for about 48 hours. No fruit formed on our plants; the 
peculiar structure of the stigmas perhaps marks their degenera- 
tion. 
Cereus THuRBERI Engelm. var. littoralis. Stems low 
branching from the base, the branches more slender than in the 
type and strongly curved. Flowers reddish, much darker than 
the type. Fruit smaller and said to be better flavored than 
typical C, Thurbert. 
On steep seacoast bluffs between San José del Cabo and Cabo 
San Lucas, Baja California, collected by T. S. Brandegee in 
1892* and later by Dr. C. A. Purpus. 
Cereus vagans. Stems prostrate, branching, light green, but 
the younger stems and joints often purple, reaching 1 m. in 
length, 20-25 mm. in diameter at base with roots springing from 
the whole length, texture rather dry and horny; ribs 8-9 rounded, 
elevated, well separated, not tuberculate; areolae of the same 
rib on old shoots 12-15 mm. asunder, woolly, the spines much 
shorter than the internodes, Spines slender but stiff, white 
or whitish, 3-6 mm. long, not regularly arranged radials 8-12 
with 1-4 slender and longer bristly ones below, centrals 2-6 
in two series. 
Collected by Mr. T. S. Brandegee on El Creston, an island in 
the harbor at Mazatlan, at various times, and later by Dr. C. A. 
Purpus, neither of them finding traces of flowers or fruit. It has 
been in cultivation in our green-house and in the open air for 
three years, and aJthough it flourishes, some of the stems reach- 
ing 2 m. in length, it has not so far bloomed. 
I am sorry to have to describe a plant without flowers or fruit, 
but it is done in order to obviate a greater evil. It has gone into
