Acclim. 52: 45. f. 9, as Cereus bavosus. 
On page 86, vol. 11, under Lemaireocereus hystrix, add the synonym: Cactus americanus 
Vitman, Summa PI. 3: 209. 1789. Ea 
Insert: Cactus americanus is based on Bradley’s illustration (Hist. Succ. PI. 12) which 
De Candolle- referred to Cereus eburneus, but as the plant came from the West Indies it is 
perhaps better referred to Lemaireocereus hystrix. 
Also insert: We have recently obtained from N. E. Brown a photograph of Haworth’s 
Cereus hystrix, with the date, ‘‘Oct. 24, 1824.” ~ 
On page 87, vol. 11, under Lemaireocereus griseus, add to illustrations: Monatsschr.

On page 89, vol. 1, under Lemaireocereus eichlamit, add to the description: 
Fruit globular, about 5 cm. in diameter, becoming dry, not edible, thin-skinned, filled with 
numerous large seeds, the surface bearing scattered areoles, these densely short-felted with clusters 
of short spines subtended by small, ovate, acute scales; seeds black, 4 to 5 mm. long with a prominent 
hilum. 
Insert: This plant is much used for hedges in Salvador and was obtained there by Mr. 
Paul C. Standley in the vicinity of Sonsonate, altitude 220 to 300 meters, March 1922 
(No. 22328), but was not seen in the wild state. It is called there 6rgano. This species 
heretofore has been known only from Guatemala and was not known to us in fruit; this 
differs from that of the other species of Lemaireocereus in being rather dry with very large 
seeds. 
Also insert: Figure 246 is from a photograph of the plant, sent by F. Eichlam in 1909 
to Washington, which flowered in 1918.
