in a large loose truss, are broadly campanulate, 3 inches across by 
2 inches deep, of a pale flesh colour, the unexpanded buds being a 
deep rose. 
See Gardeners’ Chronicle, 1888, iii., 620, and The Garden, 
1892, xlii., pl. 885. 
Rhododendron (R. intricatum x R. indicum album). 
The cross was made in 1908 and seedlings raised in 1909, but the 
plants have not yet flowered. : 
Rhododendron (R. Smirnowii x Named garden varieties). 
arge number of hybrids was obtained from crosses made in 
1893 and 1894, most of which were of very vigorous growth but 
inferior to the majority of garden varieties in their flowers. A few, 
such as those named “ G, Thiselton-Dyer” and “ Mrs. Prain,” were 
of average merit. Hybrids from R. Smirnowii are likely to prove 
quite hardy. 
Rhododendron Edith A. Boulton (R. Fortunei x R. Meteor). 
his hybrid, produced in 1894, has proved to be one of the best 
of the Fortune’ race of Rhododendrons—a race of considerable 
value in gardens, because they flower somewhat in advance of the 
better known hybrids and thereby lengthen the flowering season of 
the genus. It is curious in producing many flowers without stamens. 
Rhododendron (R. Vaseyi x R. cinnabarinum). 
Cross made in 1897. 
The hybrid is a curious-looking small-leaved shrub which has not 
yet flowered, : 
Rhododendron (R. campylocarpum x R. Esmeralda). 
One of the most desirable things in regard to the cultivation of 
Rhododendrons is the production of a race with good yellow 
flowers, It was thought that something in this way might be done 
by crossing these two, the former of which is pale yellow, the latter 
light red. About 25 hybrids were obtained from this cross made in 
1897, only one of which has yet flowered, and this was as pale a 
yellow as the mother plant. 
Rhododendron (R. Griffithianum x R. campylocarpum). 
The hybrid, produced in 1898, bears pps ame flowers, but 
is not of striking merit 
Rhododendron Griffithianum ¢ was also crossed with various garden 
varieties. The best of the hybrids obtained were those from flowers 
pollinated with “Grand Arab” and “ Ascot Brilliant.” The trusses 
are red, The plants are only half-hardy at Kew. 
Rhododendron (R. ciliatum x R. Edgeworthii). 
The hybrid, obtained in 1900, is of interest in being exactly 
similar to the variety called “ Princess Alice.” a well-known green- 
house plant. : 
Rosa (R. macrophylla x R. rugosa). | 
It is impossible to obtain roses true from seed gathered from 
the plants growing together in the collection, because of the cross 
fertilization caused by bees. The result is nearly always @ 
worthless mongrel, and the propagation of roses by seed from this 
source is no longer attempted. Amongst the hybrids formerly so 
raised, however, is a very handsome unnamed one with the
