begin to fade, the supply of water 
should be gradually lessened, till, at | 
last, very little is given, and that not | 
oftener than once a week. ‘The 
plants are propagated by cuttings, | 
which should be laid on a shelf two | 
or three days to dry before planting, 
or they will rot. When plants of 
Crassula are not well drained, or if 
stagnant water is retained round 
the roots, by letting water stand in 
the saucer, the stems are very apt 
to damp off. C.cocctnea and some | 
other species were separated from 
formed inte the genus Kalosanthes ; 
put this name does not appear to 
have been adopted by many persons, 
and the plants are still generally 
called Crassula, both in nurseries 
and private collections. 
Cratz\cus. — Rosdcee. — The 
common Hawthorn, C. Oxyacantha, 
is so well known for its fragrant and 
beautiful flowers, that most persons 
will be anxious to know the other 
species of the same genus; and, in 
fact, several of the North American 
thorns are the most ornamental low 
trees we have in our gardens and 
shrubberies. The species are all 
hardy, and they all flower and fruit 
freely, and are equally ornamental 
in both states. Almost all the 
flowers are white ; but the fruit 
varies in colour, some being scarlet, 
some yellow, some purple, and some 
green. The fruit varies also in size 
from that of C. spathulata, which 
is not larger than a grain of mustard- 
seed, to that of C. Mexicana, which 
*; nearly as large as a Golden Pippin. 
‘The fruit of C. Azarélus, C. Arénia, 
and C. tanacetifolia, all large and 
yellow, and that of C. edoratissima, 
of a bright coral colour, are all very 
ood to eat ; and many persons do 
not dislike the haws of the common 
Hawthorn. There are nearly a 
hundred different kinds of Crate\gus, 
including the hybrids and varieties ; 
of the common Hawthorn. The 
handsomest species for their flowers, 
are the red-blossomed and double- 
flowered Hawthorns ; the hand- 
somest for their leaves, are the 
different kinds of Cockspur-thorn 
| (C. crus-gélli), C. punctata, C. 
pyrifolia, C. prunifolia (the leaves 
of which die off of a deep red), and 
C. Celsii: and the most curious for 
their fruit are C. Douglassii, C. 
mexicana and C. orientalis. The 
earliest flowering in spring are C. 
_purierpa, and C. nigra, the latter 
the others by Mr. Haworth, and | 
of which is said to attract nightin- 
gales ; and the Glastonbury thorn, 
a variety of the common Hawthorn, 
often flowers at Christmas. C. 
Oxyacantha péndula, and C. O. 
regine, Queen Mary’s thorn, have 
both pendulous branches; and C. 
O. stricta, and C. tanacetifolia 
grow stiff and upright, like a Lom- 
bardy poplar. C. tanacetifolia and 
C. odoratissima have bluish-green 
leaves, which look as though they 
had been slightly powdered ; and 
C. crus-galli splendens, and several 
other kinds, have their leaves of a 
shining dark blackish green. C. 
pyracantha is an evergreen, and has 
a very good effect when trained 
against a wall, from its shining 
leaves, its bunches of pure white 
flowers, and its brillant scarlet fruit, 
which are so abundant in winter as 
to induce the French to. call the 
plant Buisson ardent, or the Burn- 
ing Bush. 
All the species of Crategus will 
grow well in any soil that is natu- 
rally dry; but if planted in marshy 
ground, they will be stunted in their 
growth, and their leaves and fruit 
will become spotted and unhealthy. 
The common Hawthorn is propa- 
gated by seeds, which often lie two 
years in the ground before they ger- 
minate, if not prepared before 
sowing, by being suffered to lie for 
several months in what is called a 
and of these thirty-one are varieties | rot-heap ; and which is often turned
