and a perfect match produced, by simply cutting a branch, which 
will form one half of the arch, down the middle with a saw—the 
outline may then be had as regular as that of masonry. Another 
little matter should be borne in mind by those who undertake 
this kind of work, which is always to fasten the bark on securely 
with small nails; for, however tight it may be when first used, 
there is little doubt that the action of the sun will speedily sepa¬ 
rate it from the wood, unless some precaution of the kind is 
previously taken. As a concluding remark, we may mention 
that the appearance of detached objects of this nature is greatly 
heightened by placing them upon smooth turf rather than in any 
other position, the warm brown hue of the bark then harmonises 
in a pleasing manner with the rich green of the turf, and the eye is 
not fatigued, as would be the case did the still warmer tone of 
gravel or the dazzling white of a stone terminate the glance.

Asclepiadace^e. —Pentandria Monogynia. 
Sarcostemma ( Philibertia ) Campanulatum. For this new and 
very distinct species we are indebted to Messrs. Veitch and Sons, 
of Exeter, who sent specimens in October last. Our memoran¬ 
dum gives no information of its native country, but we presume 
it to be Peru. 
Its broad cordate leaves, and large yellow campanulate flowers 
(mottled inside with brown), are strikingly different from those 
of other previously-described Sarcostems, to which M. Decaisne 
reduces'the Philibertias. More especially the base of the leaves 
being very deeply heart-shaped, with the lobes almost over¬ 
lapping, is very different from what is found in S. solanoides 
and grandijlorum. 
It is a pretty little shrubby greenhouse climber, well adapted 
for training over ornamental wirework fastened to the pot; and, 
like most of the plants belonging to Asclepiads, it requires a rich
