layers and become completely inert. The absorbing 
organs, the leaves, and the ends of the root, do not live 
more than a year. Similar productions succeed them 
the next year. in 
“Tt is, then, in reality a new tree that developes itself 
and annually coversthe old one, in which there has ceased 
to be life. The origin of this new tree is in the buds 
Placed upon the branches of the preceding year, 
and which may be compared to seeds. If, in plants 
called annuals, such as Flax and Mustard, this accu- 
mulation of individuals one over the other is not found 
as in trees, it is because the very abundant fructifica- 
tion of those plants wears out their tissue, and annihi- 
lates their vital force ; there is no production of buds 
to preserve life in the layer of the liber, and so furnish 
a new vegetation the following year. The consequence 
is that these plants dry up directly after the fruit is 
come to maturity. That is so true, that if you hinder 
them from ripening fruit by cutting off the flowers as 
they open, you will see buds forming at the axil of the 
leaves ; the liber keeps itself alive beyond the ordinary 
time, and the following year these buds give birth to a| making their app i if not 
new individual which entirely covers the old one. 
This leads us to conclude that trees, if we consider only 
the essential living parts of the individual, scarcely pro- 
long their existence beyond two or three years. But|was in bloom, the beautiful waxy-looking flowers 
if we give the name of tree to the whole, both of the 
living parts and the parts inert, such as the old woody 
layers, we can then say that there is no natural term to 
their duration, because the vital forces are as energetic 
in the liber and buds of an Oak of 1000 years old as in 
those of 30 years old. The death of trees, considered | 
under the last point view, is, then, always accidental. 
Nevertheless, some kinds appear to yield to the in- 
fluence of accidental causes more easily than others. 
Thus, Poplars and Chestnuts, expire sooner than ibeOak 
and Yew, &e.; that is to say, owing to their tissues 
being less compact, and softer, they are more easily in- 
fluenced by the destructive causes which are constantly 
acting upon them. In fact these trees, when they are 
placed in localities beyond the reach of the causes which 
shorten their duration, live as long as the Oak and, Yew. 
Lime-trees and Chestnuts of many hundred years old 
may be cited as examples."

25. ScmunERTIA GRAVEOLENS. Strong scented Schu- 
bertia. Greenhouse Climber. (Asclepiads.) Brazil. 
This plant was first published in the present work, in 
January 1838, under the name of S. graveolens, from a 
small specimen furnished by the Mes Henderson, 
of Pine-Apple Place. Afterwards Dr. Graham mistook 
Gra 
it for a Physianthus (or Arauja) and published an 
account of it in the Botanical Magazine, calling it auri- 
comus or the golden-haired, in allusion to the long brown | 
hairs which clothe it. Mr. Glendinning, of Turnham 
Green, has furnished the following memorandum of its | 
habits and cultivation :—* When Stephanotis floribunda 
Made its appearance it was generally considered, and 
justly, the finest twining plant in cultivation. The 
present subject is not inferior to it under good culture. 
The flowers are rather larger, and quite as fragrant ; 
they are likewise produced in great profusion. The 
plant which was exhibited by me before the Horticul- | 
tural Society last autumn, and awarded a Banksian 
medal, remained in bloom quite four months ; thus 
rendering it a most useful and desirable plant at a 
season peculiarly distinguished by paucity of flower. 
I have found the following treatment in its cultivation 
suitable to it. When the flowers begin to fade, it 
should be allowed quietly to go into a state of repose, 
when it will almost become deciduous, Early in March 
it should be shaken out of the pot, the soil cleared 
entirely away from the roots, and repotted in rough 
peaty soil with a little turfy loam, adding a small 
Portion of sand; these should be intermixed. Select 
Pots of rather large dimensions, as it delights in root- | 
Yoom; well drain the pots,and spread the roots out 
amongst the soil when potting it. Settle the whole

This was sent from Shanghai, by Mr. Fortune, under 
the name of a double Convolvulus, and is the first plant 
of its order that has been mentioned as producing 
double flowers. The latter are of a delicate pink colour, 
and are found to be about as large as those of a 
double Anemone, If it should prove to be hardy, it 
will form a valuable addition to plants of that kind.
