its length; marginal teeth 6-12 lines apart, only 1 or at most 1^ 
lines long, hard and sharp, deep brown. The flowers are report¬ 
ed as having a yellowish-green tube ; limb and filaments and the 
anthers, before opening, are orange. The flowers before m^ 
belong to two forms, one with longer (1 inch) pedicels and larger 
flowers, the other with smaller flowers on shorter (3-5 Ifnes) 
pedicels. The ovary of the former is 16-18, the tube 4* and the 
lobes 10-11 lines long; filaments not twice as long as lobes } an¬ 
thers 11 lines long. The ovary of the smaller flower is 15, tube 
2, lobes 7-8 lines long, and the exsert part of the filament longer 
than the whole perigon ; in the former the stamens are inserted/ 
a little below the base of the lobes, in the-latter at the very base 
itself. The capsule of the latter is 1 i-i f inches long and 7-8

On the arid hills which overlook the sandy strand of the Pacific 
in the southwest corner of California, where the boundary i$ 
marked by the initial monument, this fine species, growing t©«- 
gether with Cereus Emoryi , was discovered by Dr. Parry M 
■1850, and a full description made ; from his memoranda Messrs'. 
Parker and Hitchcock of San Diego re-discovered it a few months 
ago and supplied me with most instructive photographs and grains oval, 
excellent specimens ; last summer Dr. Palmer collected it with f e ^‘ * ^tyl<
