and somewhat bell-shaped, like those of M. Lennei ; all the petals are 
flushed, some considerably, with a bright deep rose. This variety 
was raised from seed gathered from a plant of M. Lennei, but it flowers 
rather earlier than its parent. 
Planters must on no account miss M. hypoleuca, a large-growing 
deciduous tree of erect habit attaining a height of 50 to 80 feet. The 
leaves are 12 to 18 inches long, pale green with a rosy flush, and this 
gives the plant a very distinct appearance. The flowers, which are 
produced in June, are 8 inches across, creamy white in colour, with a 
mass of bright purplish-red stamens in the centre ; they are strongly 
scented. This is a most striking and beautiful tree, and appears to 
be hardy generally in England. 
M. Kobus has not attracted so much attention as it appears to 
deserve. In Japan it becomes a magnificent flowering tree 70 to 80 
feet high, and it seems very probable that it will attain similar propor- 
tions in this country. In the Exeter nursery plants seven to eight years 
old are already 15 and 16 feet high, with a strong main tree-like stem 
branched about 5 to 6 feet from the ground. The flowers are like 
those of M. stellata, but with rounder petals ; they are about 5 inches 
in diameter, with six pure white petals, and the seeds are bright red. 
This species is rather slow to flower at first and only bears a few 
blossoms in the nursery state, but as it grows into a larger tree it 
produces its flowers almost as freely as M, stellata, and as it is perfectly 
hardy it is well worth cultivating. 
M. salicifolia is a plant of close, compact pyramidal habit ; it 
has small green leaves. It is a deciduous species of slender but strong, 
upright growth, attaining a height of about 15 to 20 feet. It bears 
innumerable white flowers, much like those of M. stellata, but larger 
and with longer petals, and these flowers stand out conspicuously 
on the slender branches. Plants 6 to 7 feet high of pyramidal shape 
were a sheet of bloom on April 23, 191 9. At the Exminster nursery 
two trees attained a height of 10 to 12 feet in about six years and showed 
great beauty. The seeds are scarlet and are produced very freely. 
It was introduced to this country from Japan about 1908, and appears 
to be quite hardy. 
M. Watsoni grows into a stiff tree which is not by any means 
ungainly ; there are trees in the West of England 15 to 20 feet high. 
It is well worth a good position in the garden, as the leaves are large 
and pale green. The flowers are borne continuously from May to 
August and are large and of a beautiful creamy white (fig. 189), 
with a rosy hue and very strongly scented of allspice. It grows 
particularly well in a warm light soil, whereas on stronger soil the 
shoots are apt to die back. 
M. tripetala (the Umbrella tree) and M: acuminata have been 
cultivated for many years in this country, and some large specimens 
are to be found. 
M. tripetala is a deciduous tree attaining a height of from 15 to 
30 feet, with lanceolate leaves which are often 18 to 20 inches long and
