28 PRESENT-DAY GARDENING 



crosses were seen by Mr. Mangles, and described in the 

 Gardeners' Chronicle in July of that year. They are still 

 in cultivation in Scottish gardens, and they so closely re- 

 semble the hybrid R. kewense (Griffithianum x Hookeri), 

 that they might easily pass for that plant. In April 1882, 

 Mr. Mangles exhibited his hybrid Alice Mangles, which he 

 raised from R. ponticum and R. Griffithianum; it had flowers 

 4 inches across, whitish-lilac in colour, and very fragrant. 



R. Manglesii, raised by Messrs. J. Veitch & Sons from 

 R. Griffithianum and the white-flowered album elegans, is 

 of excellent habit and very floriferous, the flowers in erect 

 racemes, their colour blush-pink in bud, pure ivory-white 

 when expanded, with crimson spots on the upper segments. 

 Forms of R. Manglesii are now known under such names 

 as White Pearl, Princess Juliana, Gauntletii, and Loder's 

 White, &c. R. kewense, raised at Kew from R. Griffithianum 

 and R. Hookeri, first flowered in the Temperate House in 

 May 1888. It bears large, erect racemes of flowers, each 

 4 inches across, and varying in colour from white to deep 

 rosy pink. It is quite hardy, and, if it escapes late frosts, 

 it makes a grand display in May. 



In the garden of Miss A. Mangles at Littleworth, Tong- 

 ham, Surrey, there is an exceptionally rich collection of 

 Rhododendrons, including many of the hybrids raised by her 

 brother, the late Mr. H. J. Mangles of Haslemere. There 

 are many Griffithianum crosses amongst them, two of the 

 best being Isabella Mangles and Liza Stillman. All these 

 hybrids are perfectly hardy in the south and west of 

 England. 



Another batch of Griffithianum hybrids was raised by Mr. 

 R. Gill in the garden of Mr. H. Shilson, Tremough, near 

 Falmouth, by crossing that species and R. Thomsonii. The
