1900 SUPPLEMENT—RECENT INTRODUCTIONS, &cC. 
Cacti—continued. 
Epiphyllums are treated as follow = Cuttings of Pereskia 
are rooted and grown on to the required size, and in the 
month of September they are headed down, the tops being 
used as cuttings. Grafts of Epiphyllum are then prepared 
by cutting them to the required length, usually about 6in., 
and removing a thin slice of the fleshy stem on each side so 
as to form a flat wedge. The stem of Pereskia is then 
split down about lin. with a sharp knife, and into this 
the wedge of the graft is inserted, and fastened either by 
means of a small pin passed through the stem and graft 
about half-way up the slit, or by binding round them a 
little worsted or matting, the former being preferred. 
The worked plants are then placed in a close handlight 
or propagating-frame, having a temperature of about 
75deg. where they are kept moist by sprinkling them 
daily with water; they must be shaded from bright 
sunlight. As soon as a union has been effected, which 
will be seen by the grafts beginning to grow, the ligature 
and pin should be removed, and the plants gradually 
hardened off by admitting air to the box, till finally they 
may be removed to the house where it is intended to 
grow them. In a cottage window this operation may be 
successfully performed if a box with a movable glass top, 
or a large bell-glass, be used to keep the grafts close till 
they have taken.

RIA RECURVA ON CEREUS 
NYCTICALUS. 
For the spherical-stemmed kinds of Mamillaria, Cereus, 
Behinocactus, &c., a different method is found to answer. 
Instead of cutting the base of the graft to a wedge shape, it 
is simply eut across the base horizontally, or, in other 
words, a portion of the bottom of the graft is sliced off, and 
a stock procured which, when cut across the top, will about 
fit the wound at the base of the scion ; the two sliced parts 
are placed together, and secured either by passing a piece 
of matting a few times over the top of the graft and under 
the pot containing the stock, or by placing three stakes 
around it in such a way that, when tied together at the top, 
they will hold the graft firmly in position. Another method 
is that of cutting the base of the scion in the form of a 
round wedge, and then scooping a hole out in the centre of 
the stock large enough to fit this wedge; the scion is 
pressed into this, and then secured in the manner above 
mentioned. 
To graft one spherical-stemmed kind on to three 
columnar-stemmed ones, the latter must first be estab- 
lished in one pot and, when ready for grafting, cut at the

top into rounded wedges, three holes to correspond being 
eut into the scion. When fixed, the top should be securely 
fastened by tying it to the pot, or by means of stakes. 
For this last operation patience and care are necessary 
to make the stocks and scions fit properly; but if the 
rules that apply to grafting are properly followed, there 
will be little fear of the operation failing. In the accom- 
panying illustrations, we have a small Mamillaria stem 
grafted on to the apex of the tall quadrangular-stemmed 
night-flowering Cereus (see Fig. 192), and also a cylindrical- 
stemmed Opuntia worked on a branch of the flat, 
battledore-like Indian Fig (see Fig. 193). 
CADAMBA. Included under Guettarda (which see).
