302 GENERAL REVIEW. 



most successfully used in crossing with R. Lobbii. These 

 crosses grow well in a warm greenhouse temperature, and 

 flower freely, their elegant clusters of bright rose, white, salmon, 

 or scarlet flowers being agreeably odorous. R. " Duchess of 

 Edinburgh," raised from R. " Princess Royal" and R. Lobbii, is 

 a vivid scarlet variety, and one of the finest in the class (see 

 ' Florist,' 1874, p. 145, for coloured figure and description).

Bryanthus. B. erectus is one of the most beautiful of all 

 dwarf hardy shrubs, and is a hybrid raised by the late Mr 

 James Cunningham, of the Comely Bank Nurseries, Edinburgh. 

 It is the result of a cross between Menziesia ccerulea and Rhodo- 

 dendron chamcecistus, and most nearly resembles the first-named 

 plant. Apart altogether from its beauty, however, this plant is 

 of peculiar interest to the hybridiser as being a true bigen- 

 eric hybrid. 



THE EPACRIS FAMILY (Epacridaceec). 



Epacris. A genus of showy, free-flowering, erect-growing 

 greenhouse shrubs from Australia, similar in general habit of 

 growth and mode of flowering to Ericas, but differing in points 

 of structure and geographical distribution. They are readily 

 propagated by cuttings of the young growth inserted in well- 

 drained pots surfaced with sand, as recommended for Ericas. 

 In some cases it will be necessary to place the plants in heat to 

 obtain cuttings, as is also the case with slow-growing Heaths. 

 Nearly all the kinds in cultivation are hybrids or seminal varie- 



* It is interesting to find that Mr W. W. Buller also obtained a hybrid 

 very similar to this, and from precisely the same parents, and this plant 

 was exhibited at South Kensington on March 6, 1866 (see Jour. 'Royal 

 Hort. Soc.,' 1866, p. 31).
