. 
e 
KOELREUTERIA (named after Joseph G. Koel- 
reuter, 1733-1806, once Professor of Natural History at 
Carlsruhe). ORD. Sapindacee. A monotypic genus. The 
species is a small, handsome, hardy deciduous tree, from 
North China, having a picturesque, irregular habit of 
growth. Any ordinary garden soil suits it; but it thrives 
best, and flowers most freely, in a sheltered situation. 
Propagated by cuttings of the young shoots, in spring; 
or by layers, in early autumn.

KCG@NIGA (name revived by Robert Brown, in com- 
memoration ae Keenig, formerly of the British 
Museum). ORD. Crucifere. A small genus of very 
pretty hardy plants, included, by Bentham and Hooker, 
under Alysswm, but which, for garden purposes, may be 
kept distinct. Flowers racemose or clustered; petals 
entire; pouch sub-ovate, with flattish leaves; cells one or 
few-seeded. The species are of easy culture in any 
ordinary soil, and may be increased by seeds, sown in l 
spring. —

KOHL-RABI (Brassica oleracea Caulo-rapa). Kohl- 
Rabi is a very distinct vegetable, not very largely cul- 
tivated, except as a field crop. It comes between the 
Cabbage and Turnip, and is generally used as a substitute 
for the latter. The upper part of the stem swells into 
a large fleshy head above ground, resembling a Turnip 
Fig. 364. KOHL-RaBI, 
(see Fig. 364). Kohl-Rabi has several advantages over 
some other vegetables, and consequently deserves a place 
in gardens. It is exceedingly hardy, withstanding even 
severe frosts, and also resists drought much better than 
the Turnip. : 
Cultivation. Like all other plants of the Brassica 
tribe, Kohl-Rabi is raised from seed, which should be 
sown outside (any time from April to June, inclusive), 
in an ordinary seed bed, or where the crop is intended 
to be grown, In the former case, transplant, when 2in. 
high, into any good, well-manured ground, allowing a 
distance of about 1}ft. between the rows, and 1ft. in 
the rows; and, if the latter plan is adopted, thin out 
to these distances. Water should be given for a time 
until fresh roots are emitted. An occasional hoeing, 
to keep the surface soil open and clean, is nearly all 
that will be necessary for after-treatment. The fleshy 
heads are fit for use when about the size of a Dutch 
Turnip. The crop is frequently of great importance 
when failure with Turnips is caused by insects or drought, 
which seldom affect the Kohl-Rabi. ; 
Sorts, There are about half-a-dozen sorts in culti- 
vation, but only two are reconimended for garden 
purposes; the others are more or less coarse and 
vigorous "in habit. These are Early Purple Vienna 
‘and Early White Vienna, dwarf and useful sorts, the 
bulbs varying chiefly in the colour of their skins. They 
are not good if allowed to get old and large before 
being used.
