274 GENERAL REVIEW. 



E. glauca, now so much used in edging flower-beds, and 

 the large-leaved E. metallica. In habit it is exactly inter- 

 mediate between its parents, and forms a noble plant for the 

 centre of panels and similar positions in carpet-beds. 



E. rotundifolia, a strong-growing and very symmetrical plant, 

 nine inches across when fully developed, was obtained by 

 crossing Mr J. Seden's hybrid, E. glauco-metallica, with E. 

 secunda major. Mr R. Dean first exhibited it at South Ken- 

 sington, November 10, 1875, when it received a first-class 

 certificate. 



E. Schedeckerii is a neat-habited hybrid of Pachyphylloid 

 habit, and is the result of a cross effected between E. secunda 

 glauca and Pachyphytum bracteosum. 



Mr W. Ingram, of Belvoir, raised a distinct hybrid between 

 Echeveria secunda glauca as the male, and Pachyphytum 

 bracteosum as the female or seed-bearing parent. Its foliage 

 resembles the pollen -parent, and its flowers the seed -parent. 

 This plant was first shown at a meeting of the Royal Horti- 

 cultural Society, Oct. 2, 1872. 



E. undulata. This is a hybrid raised by M. de Smet be- 

 tween E. atropurpurea and E. (gibbiflora) metallica. 



E. retusa glauca. This is one of Mr Bull's hybrids between 

 E. retusa and E. secunda. 



E. carinata is said to be a hybrid between E. (gibbiflora} 

 metallica and E. atropurpurea. 



E. luteo-gigantea is a hybrid from E. retusa fertilised by pol- 

 len of E. macrophylla, and was raised by M. Rendatler of 

 Nancy. 



E. pruinosa is said to be a hybrid between E. lingucefolia and 

 E. coccinea. 



E. floribunda splendens and E. miniata are hybrids raised 

 by M. Rendatler of Nancy ; but I cannot lay hands on their 

 parentage. 



E. scaphylla. This is a hybrid raised by M. Deleuil from 

 E. agavoides, fertilised with pollen of E. linguce/oKa. 



E. spathulata is a hybrid between E. bracteosa and E. 

 grandiflora. 



It is a curious fact that many of these hybrid Echeverias 

 are more robust than either of their parents ; and it would be 

 interesting to know whether they bear perfect i.e., fertile 

 seeds, or whether (as is often the case with other hybrids) their 

 vigour is due in some measure to their sterility. 



The following hybrid Echeverias were raised prior to 

 1874 by M. J. B. A. Deleuil (see ' Belg. Hort.,' 1874, p. 

 329)^
