AUBRIETIA (named after M. Aubriet, a famous 
French botanical draughtsman). ORD. Crucifere. A small 
genus of hardy evergreen trailers. Racemes opposite the 
leaves, and terminal, lax, few-flowered. Leaves ovate or 
oblong, entire or angularly toothed, hairy. They make 
excellent rock plants, and will thrive in a deep rich 
loam anywhere, excepting under the shelter of trees. 
Cuttings struck, or seeds sown, during April or May 
generally make fine, dense, cushion-like growths, if trans- 
planted on to a somewhat cool or shaded border, and care- 
fully lifted in the autumn; the cuttings are best “ drawn,” 
or grown until they are soft, in a frame before they are 
removed. Where a stock of old plants exist, layer the long 
slender branches any time after flowering, and cover with 
a mixture of sand and leaf soil; they will then root freely 
and establish themselves in time for spring blooming, for 
which purpose, when grown en masse, they are most useful. 
After flowering, they may be divided and transplanted.

A. d. Eyrei (Eyre’s).* A very fine variety, with a free branching 
habit, and large flowers of a rich violet-purple colour, rather 
longar than broad. A. olympica is very near, if not identical 
with this. 
A. d. græca (Grecian).* fl. light purple. h. 4in. Greece, 1872. 
One of the best and largest flowered forms; very vigorous 
grower, with neat compact habit. A variety of this, named 
superba, has rather deeper-coloured flowers, produced over a very 
extended period. (R. G. 697.) 
A. d. urea (purple).* Larger flowers and more erect habit 
than the type. l. broader, with two to five teeth. Stems more 
leafy. There is a variegated form, which is very pleasing and 
pe useful for carpeting or edging small beds, See

A. d. violacea (violet).* -This is a hybrid form, even finer than 
Campbelli, with large deep violet-purple flowers, fading to reddish- 
violet, and is more effective than any of the others. 
A. Hendersonii (Henderson’s). A synonym of A. d. Campbelli. 
AUCUBA (the Japanese name of the shrub). ORD. 
Cornacew. A genus of hardy evergreen shrubs, thriving 
better than any other in the smoky atmosphere of dense 
cities. They grow in ordinary well-drained garden soil, and 
require no special culture. If grown in pots, they should be 
planted firmly in rather sandy yellow loam, with plenty of 
drainage. They should not be allowed too large pots, or 
an unfruitful growth is likely to result. During the grow- 
ing season,an abundance of water is needed, which must be 
lessened when the plants are fully developed. If cultivated 
in the greenhouse or conservatory, they should be plunged 
out of doors during summer. ‘To insure a good supply of 
the very ornamental berries, which are produced on the 
female plant, careful fertilising is necessary. The time 
for applying the pollen is when the pistil exudes a slightly 
gummy substance, and otherwise shows signs of maturity. 
When it happens, as is sometimes the case, that the male 
blooms are open and the pollen mature before the female 
blooms are ready, the pollen should be collected on a dry 
camel-hair pencil, transferred to a piece of glass, and 
covered over by another piece, both of which must also be 
dry. It may be applied afterwards when wanted, as it 
retains its power for some weeks. Propagated by cut- 
tings, inserted in any light sandy soil, with or without a 
covering, in spring or autumn; or readily increased from 
seeds, sown as soon as ripe.
