Greenhouse Rhododendron James Whitton. 
This is a cross between. Duchess of Bueoleuch (a white flat 
ijiety) and a yellow trumpet variety raised by the late Isaac 
aider son Heudiyf of Hay Lodge', Trinity, Edinburgh. It 
trembles both parents very much : is, in fact, a perfect blend, 
[he trumpet parent can be easily traced in the shape and also 
h the colour of the flowers, which are a pale yellow at first, 
ut gradually whiten up until they are almost pure white. It 
; of a robust floriferous habit, and was awarded a tnst-class 
ertificate at the Spring Show of the Royal Caledonian Hoi- 
icultural Society in May, 1902. I got several other good 
lowers by using the same pollen on two trumpet 
Varieties—Countess of Haddington, and a white 
innuiued seedling. Two of these crosses have 
:iven bright yellow trumpet flowers, but a great 
jnany of the seedlings have not bloomed yet. 
It might interest some of your readers if I 
Explain here what a narrow escape I h id of 
uissing these crosses. I heard through a friend 
hat there was a. grand yellow Rhododendron 
n bloom at Hav Lodge. As. I was on the out- 
ook for new blood at that time, I was not long 
n making my appearance at Hay Ledge. I 
vas told, however, that I was too late, as the 
list flowers had dropped off the day before, but 
hat I might see the plant. "W hen looking at 
lie plant I also looked under the stage and found 
he two flowers. A close inspection showed me 
hat there was still a chance of a cross, but 
die worst part of the business was that both 
lowers were quite wet with the drip from the 
plants that had been watered that morning. I 
took my prize home with me and placed the 
flowers on a slate on the hot-water pipes, and 
was able to make niv crosses by mid-day.

petition by Mr. William Young Bryson, 5-°>, 
East London Street, Edinburgh, and was 
the best line drawing. The flowers of the 
Rhododendron originally measured about 
41 in. in diameter, and the illustration 
show them al out two-thirds natural size.

Odontoglossum crispum Persimmon. 
We are now in a position to illustrate the 
above magnificent Odontoglot. Those in¬ 
terested in its description and history will find 
|a paragraph concerning the same on page 347. 
Tetratheca pilosa 
About twenty years ago, when exhibitions of 
specimen plants were common, the above plant 
was veiy frequently represented in colic.Lons, 
and the public bad a number of opportunities, of 
seeing it. Now it is very muck neglected, like 
the Heaths. 
’The Tetrathecas are closely allied to the Poly¬ 
galas, differing chiefly in having regular flowers. 
In habit they closely resemble the Heaths, and 
similar treatment under cultivation. The soil s 
chiefly of peat, and be watered in the same careful manner 
as are the Heaths. They require the temperature of a. cool 
greenhouse, plenty of ventilation, and exposure to light. 
When grown for exhibition purposes they squire"a consider¬ 
able amount of staking to support the slender, twiggy branches, 
especially when laden with their flowers. For ordinary 
decorative purposes, however, large plants are quite unneces¬ 
sary, and very handsome specimens may 1 e obtained in 43-size 
pots, and which will be a mass of bloom if grown under the same 
cultural conditions as Heaths, in such a case, a single stake 
would be sufficient, and may not be necessary at all, unless the 
branches are unusually long. Plants in this condition may be 
utilised for any purpose as the- Heaths during the spring and 
early summer months, and are certainly very pretty for such 
a purpose. 
The illustration given on p. 361 represent - a plant such as we 
describe, and which wars exhibited at a recent Drill Hall meet¬ 
ing of the Royal Horticultural Society by Messrs. W. Bale-bin 
A Sons, Hassocks Gate, Brighton, Sussex.

Rhododendron James Whitton. 
Prunus triloba. 
One of the Apricot tribe. This is one of the most profuse as 
well as one of the handsomest of spring flowering shrubs. It 
lias large, globose, rose-coloured double flowers, studding the 
annual branches. As a wall plant, spurred in after flowering, 
it is very effective, also 1 massed in beds, the plants being cut 
hard in after flowering, when it will produce shoots 2 ft. to 
3 ft. long, which, in the following spring, will be covered with 
flowers. Native of Chin?..
