VOL. 5] Notes on Cactee. 3 
such material glued upon a sheet of paper, attested by the author 
and deposited in an accessible herbarium, would be a vast im- 
provement on most cactus types in existence. 
CrrEeus Emoryi Engelm. often has tuberous roots of a size 
approaching those of C. Greggii Engelm. I have tried them 
cooked but found them not particularly palatable. 
C. striatus Brandg. Dr. Weber has kindly sent me a frag- 
ment of the type of his C. Diguetit for comparison. It is identical 
with C. striatus, and much more related to C. Greggzi than to 
C. tuberosus Pos. The local name of C. striatus is ‘‘Jaramataca.’’ 
It forms weak branching stems, 6-12 dm. high, all the lower 
portion of hard wood, and quite unlike a cactus stem. The 
tubers are not closely contiguous to the stems, and if separated 
never sprout, although they live for years and become green if 
exposed to the light. 
C. Orcuttii. Stems erect, branching, bright green, reaching 
a height of 3 m. and a diameter of 15 cm. with hard woody 
center; ribs 14-18, about 1 cm. high; areolz round, about 6 mm. 
in diameter and about half that distance apart, densely covered 
with short, light gray wool; spines all slender, spreading, yellowish 
brown, irregularly 3-seriate; radials 12-20, about 12 mm. long, 
deficient above; intermediates about ro, % to more than twice 
longer, less spreading, one of the upper spines of this row usually 
stouter and darker, porrect, often reaching a length of 7 cm.; 
centrals about 5, porrect-spreading a little longer than the inter- 
mediates; flowers greenish brown, darker outside, diurnal, about 
4 cm. entire length; petals short-apiculate; ovary densely covered 
with short scales, almost completely concealed by thick, rounded 
tufts of yellowish wool, in which are imbedded dark brown 
bristles 4-6 mm. long; stamens lining the upper half of the 
tube; style tips acute; fruit not known. 
The plant from which this description is drawn was obtained 
by Mr. C. R. Orcutt near Rosario, Baja California, in May, 1886. 
It was brought to him by his guide, who found it off the trail 
some little distance. The cutting was planted in Mr. Orcutt’s 
garden, and is now about 2 m. in height; has flowered but
