for convenience, in a common frame. They were retained in this situation through- 
out the summer, being liberally supplied with water and air, and sometimes 
completely exposed. About the month of November, they were removed to a 
stove in which a temperature of (30 or more degrees, Fahrenheit, is generally main- 
tained, and at the present time every specimen, thus dealt with, is exhibiting large 
bunches of flower- buds at the extremity of each shoot. Even the smallest plants, 
which have not yet been shifted out of the pots in which they were originally 
planted from the propagation-house, appear to be equally as prolific of flowers as 
those of more mature growth. 
We are happy thus to see our expectations (as expressed in vol. vi, p. 196) 
respecting the propriety of partially exposing this plant to the sun, so thoroughly 
verified. No perceptible injury — not so much as the discoloration of the leaves — 
attends the plant while passing through this ordeal ; and a full knowledge of the 
facts here communicated, will, we are persuaded, assist more in rendering it popular, 
than any recapitulation of its merits in which we might indulge. The consequence 
which followed the process of exposure in the present instance, is likewise of great 
importance as an evidence of the general good effects which would result from this 
system, if more extensively practised with plants that rarely develop their flowers. 
Only one precautionary circumstance should be borne in mind when adopting it ; 
which is, that all other plants have not such vigorous or hardy foliage as 
Mschynantlius^ and therefore require to be more gradually accustomed to direct 
solar influence. There can be little doubt that the still more splendid M. grandiflor us 
would, if subjected to the same regimen, receive a similarly potent stimulus.

Cereus martianus. The lovers of the beautiful in the Cactaceous tribe, 
cannot cultivate a plant more suited to their taste than the present ; although, we 
believe, it does not flower freely until of a certain age. In the rich collection of 
succulents at Woburn, it blossomed in April, 1839. It is nearly allied to C. 
Jlagelliformis^ but has larger and erect stems, like those of C. serpetitinus. The 
fine crimson-coloured blossoms have a long tube, and acuminate segments : they 
are large and particularly handsome. The chief differences between this species 
and C.Jlagelliformis, besides that above-mentioned, are its more deeply furrowed 
stems, and slenderer as well as much more distant aculei. It is a native of 
Mexico, and flowers very copiously in the spring months. Bot. Mag. 3768. 
Deutzia corymbusa. a notice of this species appeared in our last volume, 
under the name of D. canescens, by which appellation it is yet known in some
