4 Notes on Cactee. [ZOE 
formed no fruit. It is much the finest of the large Cerei of Baja 
California, being densely covered with bright, yellowish brown 
spines. By its flowers it is obviously related to C. Pringle: Wats. 
The guide told Mr. Orcutt that it bore in its season edible fruit 
the size of an orange, but it is possible that he confused it with 
C. Thurberi. . 
C. Scuorrit Engelm. var. australis. Stems more slender and 
upright than the northern forms: ribs in the fertile ends, often as 
many as ten; areole smalier and more distant, and the long 
spines commonly fewer and stouter; abortive spine or gland (?) 
below the acute base of areola more conspicuous. © 
Mr. T. S. Brandegee has observed that the southern form of 
Pringlei is more slender than the northern one, and I have 
noticed the same thing in C. A/amosensis Coult. and apparently 
in C. Thurberi Engelm. 
I cannot understand how Dr. Schumann is able to refer so un- 
hesitatingly to this species C. Palmeri Engelm. in Coult. Contr. 
Nat. Mus. iii. got. Engelmann described C. Schottit, which, so 
far I know, never has less than 5 ribs at maturity, always gray 
spines, and an entirely unarmed fruit, and it is inconceivable 
that he himself should describe the same species as having ‘‘3-4 
ribs, greenish-brown Spaces: and fruit armed with bunches of 
5-8 short, stout spines.’ 
The figure of the fertile areole of C. Schotttt, Monog. Cact., 
173, appears to be upside down. 
C. Schottit, C. pecten-aboriginum and, judging by Engelmann’s 
figure of the ‘‘young spines’’, C. giganteus belong to the genus 
Pilocereus as limited by Dr. Schumann. The flowering areolze 
of C. Pringlei are yet unknown to me. In C. feclen-aboriginum, 
now flowering in our garden, the fertile areolaee show a porrect 
bunch of spines, not at all spreading andso numerous that I have 
not attempted to count them. The woolly groove connecting 
the areolz in C. Pringle, C. pecten-aboriginum, &c., is a continu- 
ation of its lower border, as may be seen in the occasional 
imperfect connections.
