A synonym of 
DABCGCIA. This genus embraces only one species— 
D. polifolia, described on p. 430, Vol. TI. Seeds should 
be sown as soon as they are ripe in shallow pans of peaty 
soil, barely covering them with finely-sifted soil, and placed 
in a cold frame, or, better still, in a warm greenhonse. 
The seeds should be sown thinly, and when the seedlings 
are large enough should be pricked off into boxes of rough 
peat and leaf-mould, and stood in cold frames, and if never 
allowed to suffer for water they will be fit for planting out 
in their permanent quarters the following spring. The 
following variety is now grown: 
D. cantabrica (Cambridge). A synonym of D. polifolia. 
D. polifolia calyculata (having a large calyx). A very pretty 
garden variety, producing both white and red flowers, the calyx 
being so developed as to give the appearance of double blossoms. 
DACRYDIUM. Syn. Lepidothamnus. The ten species

DEDALACANTHUS (from dzdalos, of various

fourteen species of stove, erect, glabrous or pubescent 
shrubs or sub-shrubs, natives of the East Indies and the 
Malayan Archipelago. Flowers blue, pink CA white ?), 
sessile in the axils of opposite bracts, bibracteolate, forming 
dense or interrupted spikes ; calyx deeply five-lobed or five- 
parted ; corolla tube elongated, slender, incurved above, the 
limb oblique, spreading, five-lobed; perfect stamens two. 
Leaves entire or scarcely toothed. D. macrophyllus is an 
erect, minutely pubescent, stove, perennial herb. ‘It 
belongs to a class of Acanthaceous plants that are very 
suitable for winter decoration, flowering freely under proper 
treatment, which consists very much in careful watering at 
the time when, in their native country, little or no rain 
falls”’ (Sir J. D. Hooker). For culture, see Eranthemum. 
D. macrophyllus (large-leaved). _/l., calyx minute ; corolla pale

DZHEMONOROPS. The following species, described 
under Calamus, should be transferred to Dzemonorops, 
which is now regarded by botanists as a distinct genus : 
C. accedens (D. Draco), C. adspersus, C. Draco, @. fissus, 
C. Hystria, C. Jenkinsianus, C. Lewisianus, and C. verticil- 
laris. To the species described on pp. 430-1, Vol. I., the

cultivation.

DAHLIA. These plants are gross feeders, and require 
a rich, deep soil, if blossoms are to be fully developed. It 
ought, moreover, to be trenched about 2ft. deep, and during 
the process a good supply of rich farmyard manure worked in. 
Trenching should be done in the previous autumn, before 
the ground is saturated with the autumn rains. In fine 
weather in winter the surface should be forked over to a 
depth of 3in. or 4in.; this will allow the air to penetrate 
more fully into the soil, getting it into the very best con- 
dition for planting in the season. At planting-time it is 
best to put the permanent sticks into the ground. If the 
soil is in good condition, sufficient should be dug out in 
front of the sticks to allow of the ball of the roots to go well 
into the soil. The plants should be firmly inserted, and 
tied to the sticks at once. If the soil is not in good con- 
dition, it is an excellent plan to dig out a spit or two, and
