must take the precaution before- 
hand to prepare a rich bed or bor- 
der of leaf-mould and common 
soil—using one-fourth only of the 
latter ; and plant them in this, in 
groups or masses of considerable 
size. ‘Thus treated they will thrive 
and blossom finely, while they will 
only dwindle, and finally perish, in 
the common soil of the borders, 
however rich it may be.—Eb.] 
Kauosa'nrueEs. — Crassuldcee.— 
Mr. Haworth’s name for Crassula 
coccinea, and some of the allied 
species. See Cra’ssuna. 
Kautru'ssia. — Composite. — A 
beautiful little annual, resembling 
an aster; the ray florets of which 
curl curiously back after it has been 
expanded a short time. ‘This plant 
was formerly considered half-hardy ; 
but it is found only to require sow- 
ing in the open border in April, to 
flower in May or early in June. Its 
beauty is, however, very short-lived ; 
as its flowers have generally all 
faded, and its seeds ripened before 
the end of July. It has been named 
Charieis by Professor De Candolle, 
_ but the name has not been generally 
_ adopted. 
Keei.—The lower part of the 
flower of a pea-flowered plant, con- 
sisting of two petals, so closed to- 
gether as to resemble a little boat. 
Kenne‘pya. — Leguminose.—A 
genus of well-known plants, with 
showy flowers, which has been lately 
divided by Mr. Bentham into four 
new genera, viz.: the Harden- 
bergias, comprising those with small 
bluish or lilach flowers on slender 
branches, the type of which is K. 
monophy'lla; the Zichyas, having 
bunches of broad reddish flowers, 
with very short keels, as for ex- 
ample, K. coccinea; the Kennedyas, 
with large scarlet or crimson flow- 
ers, having long keels; and the 
Physalobiums, having flowers a good 
deal like those of the Zichyas, but 
with bladdery capsules. All the

Kennedyas are Australian climbing 
or trailing shrubs, which require a 
greenhouse in England, and should 
be grown in heath-mould, or very 
sandy loam, mixed with peat. They 
are propagated by cuttings, which 
strike readily in sand, under a bell- 
glass. 
Ke'rria.— Rosdcee.— By some 
mistake, Kérria japonica was at 
first supposed to belong to Corcho- 
rus, a genus of Tiliacee, and of 
course nearly allied to the Lime- 
tree; to which it bears no resem- 
blance, though it is still called 
Corchorus japonica in the nurseries. 
It is also singular, that though the 
double-flowered variety was intro- 
duced into England in 1700, the 
species was not intreduced till 1835. 
It is a delicate little shrub, too 
slender to support itself in the open 
air ; but when trained against a wall, 
flowering in great profusion. It 
should be grown in a light rich soil, 
and it is propagated by cuttings. 
Kipney Vetcu.—See Anruy'L- - 
LIS. 
Knapweep.—Centairea scabiosa. 
Kwavu‘t1a.— Dipsdcee@.—One spe- 
cies is a very pretty little flower, 
requiring only the usual treatment 
of hardy annuals. 
Knieur’s Star.—A kind of Ama- 
ryllis, considered by some authors 
as forming a separate genus called 
Hippeastrum. 
Knives are used in gardening for 
pruning, and also for budding and 
grafting. Pruning - knives were 
formerly characterized by hooked 
blades ; but, as I have already men- 
tioned under the article Instruments, 
straight-edged blades are now pre- 
ferred, as making a aner cut. 
The best description of budding- 
knife has a straight blade, the up- 
per half of the back having also a 
cutting edge, and the handle is ter- 
minated by a rounded end. Some- 
times a knife is made to serve as 
both a budding and grafting knife,
