At Whiteway, near Chudleigh, South Devon, 
also the property of the Earl of Morley, the 
woods are planted with Himalayan Rhodo- 
dendrons some of which are 30 feet in height, 
while many fine plants are growing in the 
gardens. These comprise, amongst others, 
Rhododendrons campanulatum and its variety 
Wallichi^ campylocarpum, cinnabarinum Roylei, 
Blandfordiajiorum, trijiorum, fulgens, nilagir- 
kum, Coofnbe Royal, Mrs. Butler, the bright 
crimson R. Br ay arum, Broughtoni, Ascot Bril- 
liant, the blush-spotted Standard of Flanders, 
gloxinicejlorum, and Black Arab, with flowers 
of deep maroon-red. The splendid specimens 
of R. Falconeri and R. grande in Lord Fal- 
mouth's garden at Tregothnan — probably the 
finest of their species in the British Isles — 
have been already quoted, as has the remark- 
able plant of R. Griffithianmn at Killiow.

RHODODENDRON DAL- 
HOUSm.* 
The plant shown in our coloured plate 
is one of the most beautiful and interest- 
ing of Himalayan Rhododendrons , from 
the size and fragrance of its flowers and 
its peculiar habits of growth. A native 
of damp forests of the Eastern Hima- 
layas, at elevations of 6,000 to 9,000 
feet, it is found growing upon the trunks 
of large trees, and rooting in the masses 
of decayed leaves, mosses, ferns, and 
other debris which accumulates in their 
branches. These conditions seemed to 
make its success in this country doubt- 
ful, butthree years after its introduction 
a small seedling plant, grafted upon the 
common Rhododendron, flowered in 
the collection of the Earl of Rosslyn at 
Dysart House. Since then the plant has 
been grown in many parts of the country, 
but is still far from common. Its habit 
is straggling and needs training to secure 
an effective plant. If left to themselves, 
seedlings will often run up a stem of 3 
or 4 feet without a break. In its own 
country it is seldom more than 6 or 8 
feet high, but is often larger under culti- 
vation. I have seen a fine plant at the 
Botanic Gardens, Birmingham, over 14 
feet high, and when in full beauty bearing 
over I ooheads offlower whose fragrance 
filled the house. On first opening, the 
flowers are of a pale yellowish-green, 
but quickly become a rich yellow and 
give off their strong fragrance which lasts 
for several days. The flowers keep their 
colour while the scent lasts, and then 
slowly change to almost pure white 
before fading. The waxy bells are quite 
small upon first opening, but grow until 
the fully expanded flowers are from 4 
to 5 inches in length, and about the same 
across the mouth. 
Several beautiful hybrids have 
been raised between this and 
other Himalayan Rhododendrons. The 
well-known R. Countess oj Haddington 
is a cross between our plant and R. 
ciliatum^ from which it has taken its 
neat habit. The flowers are lilac-pink 
in colour, with the size and fragrance 
of R. Dalhousice. R. Dalhousice var. 
hybrida is from a cross with R. for- 
mosum. Its flowers are very near those 
of our plant in size and shape, but are 
mostly pure white, with sometimes a 
tinge of pink along the centre of the 
petals. The habit of the plant is mid- 
way between that of the parents, and the 
foliage intermediate in size and quite 
smooth. R. victorianum is the result of 
crossing R. Dalhousice and the closely
