Raspberry—continued. 
. the latter spraying, paying special attention to the young 
canes ; and lastly, just prior to the flowering period. As 
Raspberry foliage is somewhat susceptible, care should 
be taken to test the Bordeaux Mixture before spraying 
in quantity. About quarter strength has been found to 
be effective and non-injurious to the plants. All the 
oid canes should also be removed and burned as a pre- 
cautionary measure. 
The following are additional varieties to those given 
in Vol. III. : 
Norwich Wonder. [Fruit large, 
flavour. A vigorous grower, and very free bearer. 
esteemed by market growers. 
Semper Fidelis. Fruit large, red, somewhat acid in flavour. 
A great and continuous bearer, fruiting after most of the 
summer varieties are over. 
Superlative. Fruit very large, conical, deep red, and of fine 
flavour. Footstalks long, canes stout, and very fruitful. A 
new variety of great excellence that has rapidly become 
popular. 
White Magnum Bonum. Fruit medium, sweet and agreeable 
flavour. A superior variety to the YELLOW ANTWERP. 
RASPBERRY BRAND, or RASPBERRY 
RUST. See Raspberry—Fungi, Vol. III. 
RASPBERRY-BLACKBERRY. Under the name 
of Mahdi, a hybrid has reen raised by crossing the common 
Blackberry with Raspberry Superlative. The credit 
for this is due to Messrs. J. Veitch and Sons, Chelsea. 
The growth somewhat resembles that of the Blackberry, 
but shows distinct traces of Raspberry blood. The frnit 
is large, produced in clusters, dark purplish-red in colour, 
and intermediate between its parents in flavour. 
RAT’S TAIL CACTUS. A very appropriate common 
name for Cereus flagelliformis. 
RATTLESNAKE FERN. See 
virginianum. 
RAUWOLFIA. To the species described on p. 279. 
Vol. III., the following shonld be added: 
R. canescens (hoary). /. reddish, small; cymes axillary, 
few-flowered. 7. quaternately whorled, elliptic, ovate, or 
obovate, acute at both ends, the larger ones Zin. to 3in. long, 
tomentose beneath; petioles gin. long. Branches somewhat 
tomentose. h. 7ft. West Indies, 1759. Syn. R. hirsuta. 
R. tomentosa is a white-flowered form of this species. 
R. hirsuta (hairy). A synonym of R. canescens. 
R. tomentosa (downy). A form of R. canescens. 
RAVENSARA (from the Malagasy words raven, 
leaf, and sara, good; in reference to the strong clove- 
like odour of the leaves). Madagascar Nutmeg. Syns. 
Agathophyllum, Evodia (of Giertner). Orv. Lawriner. 
A small genus (three or four species) of highly aromatic, 
glabrous, stoye trees, only found in Madagascar. Flowers 
small; perianth tube turbinate or obovoid, the limb of six 
nearly equal segments ; perfect stamens nine ; panicles few- 
flowered, pedunculate in the upper axils. Leaves sparse, 
leathery, penniveined. R. aromatica, the only species 
known to cniltivation, is described as Agathophyllwm 
aromaticum on p. 36, Vol. I. 
RAXOPITYS. A synonym of Cunninghamia 
which see). 
REA. A synonym of Dendroseris (which see). 
RED ADMIRAL BUTTERFLY. See Vanessa. 
RED BAY. Sce Persea carolinensis. 
RED CURRANT. See Currant. 
RED GUM. See Eucalyptus resinifera. 
RED MAHOGANY. Sce Eucalyptus resinifera. 
RED PUCCOON. See Sanguinaria. 
RED SPIDER (Tetranychus telarius). This mite 
inflicts the greatest injury upon plants under glass, and 
is especially destructive to Vines. Sulphur in some form 
is still the best remedy to employ, but to be of the 
greatest service Vineries and such-like places must have 
a moist atmosphere. A dry atmosphere is very favourable 
to the development of the pest, and mnst be guarded 
against. Outside, one of the preparations containing 
sulphur in some form should also be employed, using 
the syringe freely whenever possible. As stated in

Red Spider—continued. 
Vol. III., the Red Spider is neither an insect nor a 
Spider proper, though it approximates to the latter. 
The illustration (Fig. 644) gives an excellent idea of these 
minute and much-dreaded pests of gardens and glass- 
houses. See also Tetranychus telarius, Vol. III.

Fic, 644. Rep SPmperR (magnified 130 diameters), 
RED-FOOTED BEETLE (Luperus rufipes). Both 
Apple-trees and Pear-trees at times suffer from the attacks 
of this small, unattractive-looking beetle (Fig. 645), which 
appears on the newly-opened leaves. It is about 4mm. 
to 5mm. in length, and of a shining black except the 
feet, which, as the specific name indicates, are red. 
There is little difficulty in recognising its presence, for 
the leaves on which it has been feeding 
are pierced with innumerable small 
holes, looking as if they had been 
penetrated by fine shot. On their 
first appearance in spring numbers of 
the pests may be found upon a single 
leaf, and as they continue in the per- 
fect state a long time, they must be 
regarded as decidedly inimical to the 
trees on which they elect to dwell. 
Old and young trees alike suffer from 
their depredations, though for the 
latter they seem to have the greater 
partiality. Contrary to the custom 
of many beetles feeding upon fruit 
trees, the female of the one under 
p notice deposits her eggs in the soil 
beneath the food-plants. As the 
presence of the depredator is so easily 
detected there ought not to be much difficulty in dis- 
lodging it by shaking the trees in early spring over a white 
cloth or by spraying them with an insecticide, Paris Green 
for instance; while soot or lime “pointed” into the 
soil in antumn and again early in the new year would 
probably be of some service.

R. chinensis (Chinese). The correct name of R. glutinosa.
