522 GENERAL REVIEW. 



THE RUE FAMILY (Rutacta}. 



A group of small trees, shrubs, or herbaceous plants, princi- 

 pally natives of South Europe and the Cape of Good Hope, 

 some of our greenhouse species of Boronia, Correct, and 

 Eriostemon being natives of New Holland. The principal 

 genera besides those just named are Calodendron, Adenandra, 

 Barosma, Dictamnus, and Ruta (Rue). Nearly all the species 

 require artificial fertilisation to insure the production of seed 

 in cultivation. This is, however, but seldom resorted to, as 

 nearly all these plants are readily multiplied by cuttings or 

 layers. It does not appear to be generally known that the dif- 

 ferent species of Eriostemon succeed well grafted on the strong- 

 growing species of Correa as stocks ; and Correa cardinalis and 

 one or two others form more bushy and floriferous plants when 

 grafted on C. alba than when grown from cuttings on their own 

 roots. Plants for stocks should be struck from cuttings, and 

 as soon as they are rooted they can be splice-grafted in a close 

 case. Several pretty varieties of Correa have originated in our 

 gardens from seed. Boronia Drummondii alba is a pure white- 

 flowered plant, raised by Mr W. Smythe, then of Elmham Hall 

 Gardens, Norfolk, some time about 1867. It is the result of a 

 cross effected between Boronia Drummondii and B. pinnata, 

 both of which bear pink flowers. B. Drummondii was the seed- 

 bearing plant, and the hybrid resembles it, except in the colour 

 of the flowers. 



Correa {Native Fuchsias). A sinall genus of Australian 

 plants, represented in our gardens by one or two species and 

 several seminal or cross-bred forms. I find no records of 

 hybrids, although these plants appear to have been much im- 

 proved soon after having been introduced to cultivation. The 

 following varieties are seminal ones: C. "Brilliant," C. "Caven- 

 dishii," C. "cardinalis," C. "delicata," C. "Jardin d' Hiver," C. 

 " magnifica,"C. " Ne Plus Ultra," C. " speciosa ventricosa," and 

 others. Eriostemons struck from cuttings in a gentle bottom- 

 heat form excellent stocks on which to graft these seedling va- 

 rieties of Correa, and especially such as do not flower freely on 

 their own roots. Numerous seedlings, varying in colour from 

 white to crimson, were raised by Mr Gaines prior to 1848. 



Eriostemon (Australian May). A small genus of white- 

 flowered shrubs, represented by E. am&num, E. buxifolium, E. 

 intermedium, E. linear if olium, E. neriifolium, E. pulchellum, 

 E. scabrum, all well-known greenhouse plants. They strike 

 tolerably well from cuttings of the young growth in heat ; or 

 cuttings grafted on their own roots succeed well.
