34 Notes on Cactee. [ZOE 
1840 by M. Dumesnil, at Havre, from seeds brought by a ship 
captain from Baja California. It was a mistake of Engelmann, 
upon false information, to give it as a synonym of & viridescens, 
with which it has no analogy. Engelmann himself, however, later 
acknowledged (by letter) the error that he had committed. te: 
Californicus is much nearer E. Emory?, but differs from it in its 
spines and flowers. 
Having had occasion to study, at Paris, adult and authentic 
examples of /. Californicus raised from M. Dumesnil’s seeds, and 
to see them flower, I give here the description: 
Stem subglobular, somewhat glaucous, depressed; ribs 15-20, 
thick, obtuse, straight, swollen around the areolze; grooves sharp; 
areolze large, oval, distant, furnished with horny glands. Spines 
all strong, rounded, not flattened, lightly ringed, outer ones 7-9, 
straight, radiant, the upper 2-4, slender, yellowish, 3 cm. long, 
the five lower stouter, 4 cm. long, horny-yellow with purple 
spots arranged in transverse streaks or bands; centrals four, in 
form of a cross, of which the three upper are straight and similar 
to the lower radials, the lower (truly central) is the stoutest and 
longest of all (about 6 cm.), ringed, rounded, 2 mm. thick, 
recurved at summit, purple with a yellow point. Later all the 
spines are horny brown. 
This description is drawn from an adult. The young seedlings 
have only eight spines, one of them central, ali uncinate. 
Flowers pure canary-yellow, 5 cm. long, 6 cm. expansion, 
springing from the tomentose summit of the plant. Ovary cov- 
ered by about 24 imbricated, triangular-rounded, entire scales. 
Tube bearing a score of sepaloid scales gradually passing into 
the petals which are 40-45 in number, in 3 ranks, undulate on the 
margins and ending in a point. Stamens numerous and slender, 
the filaments deep carmine, anthers yellow. Style yellow,deeply 
divided into 16 erect stigmas. 
Echinocactus acanthodes em. Under this name Lemaire de- 
scribed, in 1839, a species ‘‘ Californian’’ raised from seeds by M. 
Courant of Havre, and well known for forty or fifty years after in 
French collections. It flowered at Monville in 1846. I have
