white, slender: style as long as the stamens : stigma of nine or 
ten spreading, bright yellow rays, covering the anthers. W./. H. 
Curr. At Tab. 4417 we have said that Cactee are almost in- 
different as to the kind of soil they are grown in, provided it is not 
retentive of moisture. The present very pretty species will thrive 
in a mixture of light loam and leaf-mould, containing a small 
quantity of lime-rubbish nodules ; the latter bemg for the pur- 
pose of keeping the mould from becoming close and compact, 
a condition not suitable to the soft and tender roots of the plant. 
If cultivated in a pot, it must be well drained; the pot being 
nearly half filled with broken potsherds, and the upper layer so 
placed as to cover the interstices, in order to prevent the mould 
from mixing with the drainage. During winter, Mexican Cactee 
do not require much artificial heat : several species are, indeed, 
known to bear with impunity a few degrees of frost. Where 
they can be cultivated by themselves, we recommend that the 
plants and atmosphere of the house should be kept in a dry 
state during winter, artificial heat being given only during a 
long continuance of damp cold weather or in severe frost ; but 
at no time during winter needs the temperature of the house to 
exceed 50° at night. In sunny days in spring the house should 
be kept close, m order that the plants may receive the full 
benefit of the heat of the sun’s rays. As the summer-heat 
increases air should be admitted, and occasionally the plants 
should be freely watered, and in hot weather daily syringed 
over-head. J. 8.
