showy plant is a native of Chili, and, like its Mexican allies, thrives if potted in light loam, with a little leaf mould and a few nodules of lime rubbish. The latter are for the purpose of keeping the soil open; it is also necessary that the soil should be well drained. In winter, water must be given very sparingly, and the atmosphere of the house should be dry; the temperature need not exceed 50 degs. during the night, and in very cold weather it may be allowed to fa

The width of the flower is over 6 in., and the stamens are arranged in a corona-like whorl inside the petals. This very fine Cactus is a native of Bolivia, whence it was introduced in 1850. When

This variety is often made very sickly by treating it as a tropical Cactus, and, like most of these plants, if once it gets into a bad condition, it

position of the flowers is shown in the figure. The tube is covered with tufts of hair-like spines, and the petals and sepals are broad, spreading, and white, tinged with yellow, as in E. cristata. The native country of this plant is not known; but it is a well-known garden Cactus, and thrives in a warm, airy greenhouse in summer, and on a dry, sunny shelf in winter.

"Independently of the large size of the flowers, which rival in dimensions those of the Cereuses, it is remarkable for the rich, delicate odour they exhale at night, at which time its glorious blossoms expand. When young, they resemble long, sooty-grey horns, covered over with a thick, shaggy hairiness, and would never be suspected to conceal a form of the utmost beauty and a clear and delicate complexion.

The petals are pure white, recurved, displaying the crown of yellow stamens, arranged in a ring about the rather small, rayed stigma. The tube is uniformly green, except that the scale-like bracts are edged with long, blackish, silky hairs. A native of
