seven inches long, prismatic or awl-shaped, and bear at the tip several flat flexible scales 
in place of spines,) the plant can have no affinity with Cereus. If the ovary should prove to 
be naked, the large flower and elongated tube would not be sufficient to separate it from 
Anhalonium Mr. Labouret, in his Monographie des Cactées, Paris, (without date, probably 
1853,) page 162, notices the position of the flower. I have seen the young buds below the apex 
of the tubercle at Kew, and the scar left by the fallen fruit at Mr. Haage’s in Erfurt, but could 
not meet with either flower or fruit itself. A. fissuratum is very nearly allied to the Mexican 
- A, sulcatum, Salm, (A. Kotchubei, Lem.,) of which it seems no living nor dead specimen is at 
present extant in Europe. The upper surface of the tubercle of .A. sulcatum is said to be deeply 
grooved, the groove being filled with silky tomentum; otherwise the tubercles are said to be 
smooth.

maturity become large and juicy ; usually their cells then burst, and form the so-called pulp, 
in which the seeds are described as nestling: ‘‘ semina nidulantia.’’
