three feet of the extremities die, and this will be the case every year until at last 
it will end in the death of the tree. The best remedy is to cut off the perpen¬ 
dicular roots as w’ell as all the infected parts, at the same time filling up the 
bottom of the trench all round and under the tree with new' soil, w’hich should 
be repeated every three or four years. Fruit trees should never be deep planted; 
if the roots be three or four inches below the surface it is sufficient, when the 
trees are firmly staked. In trimming, all the perpendicular roots should be cut 
off, and the horizontal ones spread out, if they be long, cut them a little to en¬ 
courage fibres. The way canker is produced from want of climate is, when the 
trees are swelling up their buds or some of them are even expanded, the severe 
weather, which often happens early in the spring, stops the flowing of the sap 
in its passages, and the buds and flow'ers are injured; a number of prominent 
spots like blisters appear on the last year’s wood, which afterwards crack and 
become cankered: and thus checks may be experienced more or less through 
the whole summer. The grafting apple or pear scions on stocks not congenial 
to them is apt to produce canker. The foliage of the crab points out the foliage 
of the graft suitable to be put on it. Crabs of small and prickly wood will not 
support a soft swelled-leaved scion long; they may continue a year; two at 
most will show the disagreement.—C. Doig. Cal. Hort. Trana.

New and very rare Plants, figured in the Botanical Periodicals for May— 
CL.\SS L—DICOTYLEDONOUS PLANTS, OR EXOGENES. 
MVRTACE^. 
My^rcia acris, Wild Clove Tree, or Bay-berry Myrtle. Icosandria Monogynia, 
Lin.—A highly fragrant plant, the smell of the leaves being like cinnamon, it grow's 
to a tree of considemble size, and although it has been introduced many years, is 
still but little known, having been much confounded with the Myrtuspimentaoi 
Linnaeus, which it much resembles. Flowers white, native of Jamaica. Many 
specimens have been received from the Rev. L. Gilding, from St. Vincent’s. 
Curtis’s Bot. Mag. Culture—It thrives well in the stove in a very humid 
atmosphere, potted in sandy peat soil, and is propagated by cuttings.—

ACANTHACEvE. 
Era'nthemum fcocundum. Ever-blowing Eranthemum.—A neat little shrub 
worthy of cultivation. Flowers lilac colour. Native of Brazil, said to be intro¬ 
duced by the Rt. Hon. Robt. Gordon. Culture—It requires the stove heat and 
a very humid atmosphere, it readily increases by cuttings, and flowers all the 
year round; it must be kept in a regular state of growth, for if it meets w'ith a 
check, such an amazing quantity of flowering buds are formed, that it not un- 
frequently dies in consequence of excessive fecuriditv.— Ed. Bnt. Reg.
