Raspberry-Blackberry 



( 264 ) 



Reevesia 



They pupate in the soil close to the plants, and 

 hybernate there. A watch should be kept upon 

 the tips of the young shoots, and hand picking 

 and dustings of soot may be brought into play. 



RASPBERRY-BLACKBERRY. 



The common Blackberry (Kubus fruticosus) has 

 been crossed with the Raspberry (Rubus Idieus). 

 The hybrid resulting is known as the Raspberry- 

 Blackberry. The growth closely approaches to 

 that of the Blackberry, with faint traces of that of 

 the Raspberry, while the fruit is purple red in 

 colour and intermediate in flavour between that of 

 its parents. It is borne in clusters. Culture as 

 for the Blackberry, which see. 



RAUWOLFIA. 



A genus of forty species of stove shrubs or trees 

 (ard. Apocynacese). Propagation, by cuttings in 

 heat under a bell-glass in sand. Soil, loam and 

 peat in equal proportions with sharp sand.

RAVENEA. 



A graceful stove Palm (ord. Palmse), allied to 

 Hyophorbe, which see for cultural details. In 

 appearance it resembles the Chama:doreas. 



Only Species :

 best when quite young. 



RAVENIA. 



Stove or warm greenhouse shrubs (ord. Rutaceic). 

 Both are well worth attention, but are not much 

 grown. Propagation, by cuttings of the half- 

 ripened shoots in sand with bottom heat. Soil, 

 fibrous loam and sandy peat in equal parts.

 by cuttings in sand under a bell-glass, with bottom 

 heat. Soil, fibrous loam two parts, peat one part,

RED-FOOTED BEETLE. 



Luperus ruh'pes is a small, insignificant-looking 

 black beetle with red feet. It attacks Apple and 

 Pear leaves, and is often present in great quan- 

 tities. It pierces the leaves with innumerable 

 small holes. The beetles make their appearance 

 early in the season, and as they have a compara- 

 tively long life they do considerable damage. 

 The female insect lays her eggs in the soil, 

 consequently dressing the soil with lime is recom- 

 mended. Shaking small trees in spring, a white 

 cloth being spread beneath to catch the beetles 

 that fall, is a capital plan. Spraying with Paris 

 Green, 1 oz. in 20 gallons of water, is efficacious. 



RED-LEGGED GARDEN 

 BEETLE. 



A popular name for Otiorhynclms tenubricosus. 

 This destructive little insect, also known as the 

 Apricot Weevil, does not confine its attentions to 

 that fruit, but affects Peaches, Nectarines, Plums, 

 and the roots of Raspberries. The beetle is black, 

 with tufts of yellow down. The larva; live in the 

 soil and attack the roots. Occasionally a plant 

 will collapse, and it is only then that the cause of 

 the mysterious malady is apparent. (>s'<r RASP- 

 BERRY.) 



RED SPIDER. 



One of the most formidable insect enemies the 

 gardener has to cope with is the Red Spider, 

 Tetranychus telarius. The name is somewhat 

 misleading, as the insect is not a spider but an 

 eight-legged suctorial mite of almost microscopic 

 size. In colour it ranges from rusty brown to 

 brick red. Though not a true spider it spins a 

 fine web on the under surface of the leaves. When 

 a plant is suffering from an attack of this pest the 

 leaves quickly become yellow or yellowish green, 

 mixed with whiter patches. Bad attacks will 

 cause entire defoliation. The spread of the insect 

 is promoted by drought and fire heat. Increase 

 of atmospheric moisture, fumigation, syringing, 

 and dusting with flowers of sulphur are the 

 best remedies. 



REEVESIA. 



Greenhouse trees (nrd. Sterculiaceae). The only 

 species yet introduced is thyrsoidea. Propagation, 

 by cuttings of the ripened shoots, inserted, with 

 all the leaves intact, in sandy soil, in a close frame
