RHODODENDRON, PRINCE OE WALES 
(ROLLISON’S). 
About sixteen or seventeen years ago, Messrs. Rollison, of 
Tooting, received from their Collector, Mr. Henshall, a new 
Rhododendron, which has been known since amongst growers 
of stove and & greenhouse plants as H. javanicum; he found it on 
Mount Salak, in the island of Java, at a range of from 4000 to 
7000 feet on the volcanic range of hills which runs throughout 
the length of the island; it was in some instances epiphytal, but 
more frequently it was found on the sides of the mountain, 
forming a shrub from seven to ten feet in height. This fine 
variety was figured in the ‘Florist’ for 1852, a period when 
Dr. Hooker’s Sikkim Rhododendrons were exciting considerable 
expectation. 
Considerable difference of opinion existed as to its proper 
treatment. Mr. Cole, then gardener to Mr. Collyer, of Dart- 
ford, one of the best plantsmen of the day, had treated it as a 
stove plant, and under such treatment it had so well thriven, 
that lie was enabled to grow it into a good specimen-plant in 
the course of two years. The Messrs. Rollison, we are told on 
the other hand, treated it as they did their Indian Azaleas, and 
under this it also flourished. In the hands of so thoroughly 
practical and scientific a firm it was not likely to remain, how¬ 
ever, under these doubtful conditions; it was used for hybrid¬ 
izing, and one of the results of their success is the very beau¬ 
tiful variety which we now, through their courtesy, have the 
pleasure of figuring, as the result of a cross between it and 
Rhododendron retusum , which they have named Prince of Wales, 
and describe as a conservatory or greenhouse plant, a showy 
and beautiful variety, with good foliage. 
The various species of this genus, whether they are hardy or
