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. Thomsoniu The
