m glaucum has leaves paler than
those of the species; and R. viscosum nitidum, of dwarf, compact growth,
has leaves deep green on both sides.

R. WILSONI, a cross between R. ciliatum and R. glaucum, is of remarkably
neat growth, and worthy of cultivation where small-sized kinds are a
desideratum.

The following Himalayan species have been found to thrive well in the
warmer parts of England, and in close proximity to the sea;--R.
argenteum, R. arboreum, R. Aucklandii, R. barbatum, R. ciliatum, R.
campanulatum, R. cinnabarinum, R. Campbelli, R. compylocarpum, R.
eximium, R. Fortunei, R. Falconeri, R. glaucum, R. Hodgsoni, R. lanatum,
R. niveum, R. Roylei, R. Thompsoni, and R. Wallichii.

R. Ungernii and R. Smirnowii, from the Armenian frontier, are also
worthy of culture, but they are at present rare in cultivation in this
country.

Few hardy shrubs, it must be admitted, are more beautiful than these
Rhododendrons, none flowering more freely or lasting longer in bloom.
Their requirements are by no means hard to meet, light, peaty soil, or
even good sandy loam, with a small admixture of decayed vegetable
matter, suiting them well. Lime in any form must, however, be kept away
both from Azaleas and Rhododendrons. They like a quiet, still place,
where a fair amount of moisture is present in the air and soil.

HARDY HYBRID RHODODENDRONS.

GHENT AZALEAS, as generally known, from having been raised in Belgium,
are a race of hybrids that have been produced by crossing the Asiatic R.
pontica with the various American species noted above, but particularly
R. calendulaceum, R. nudiflorum, and R. viscosum, and these latter with
one another. These have produced hybrids of almost indescribable beauty,
the flowers of which range in colour from crimson and pink, through
orange and yellow, to almost white.

Within the last few years quite an interesting race of Rhododendrons has
been brought out, with double or hose-in-hose flowers, and very
appropriately termed the Narcissiflora group. They include fully a dozen
highly ornamental kinds, with flowers of varying shades of colour.

The following list includes some of the best and most beautiful of these
varieties:--

Alba marginata.
Ardens.
Astreans.
Aurore-de-Royghen.
Baron G. Pyke.
