is superior in flavor, clearness and beauty to that which has been made 
from other Apples. A single plant will furnish a family with a year’s 
supply of jelly, and will prove a good investment on any farm or in 
any garden. If the writer in a recent issue of a Boston newspaper who, 
in discussing Crabapple trees, was unable to find a good word for the 
fruit of Malus ioensis will visit the Arboretum in October he shall be 
supplied, in the interest of public education, with enough of these 
apples to test their value when made into jelly. 
Double-flowered Cherry-trees. Small plants of a few of the Japan- 
ese double-flowered Cherry-trees are blooming this year and show what 
may be expected of these trees in this climate. The handsomest of 
them and probably the ones which can be most successfully grown in this 
climate are forms of Primus serndata, which in Japan is a large tim- 
ber tree, and has been growing for many years in the Arboretum (the 
Sargent Cherryi. The handsomest of the double-flowering Cherries this 
year is the var. albo-rosea, the Shirofugen of the Japanese. This is a 
perfectly hardy plant with sem.idouble flowers and petals pink in the 
bud, but becoming white when the flowers open. This is the double- 
flowered Cherry which has been sent in considerable numbers to the 
United States by Japanese nurseries, and is not rare in American gar- 
dens where in colder parts of the country than eastern Massachusetts 
it is perfectly hardy. Other varieties of these Cherries which are 
blooming well this year are the var. sekiyama, the Kanzan or Kwanzan 
of the Japanese found by Wilson in gardens at Arakawa, near Tokyo, 
in the Province of Musashi; it has large, double, rich rose-colored flow- 
ers. By Wilson, who has seen them all, the Sekiyam is considered the 
handsomest of all the double-flowered Japanese Cherry-trees; and the 
var. jugenzo, better known in European gardens as “James H. Veitch” 
with rose pink flowers and young leaves of a deep bronze color, like 
those of Primus serrulata var. sachalinensis of which it is also a form. 
These Cherry-trees are on the right hand side of the Forest Hills Road. 
The flowers are heavy and hang on long, slender stalks, and are easily 
broken off by heavy winds which have already done a great deal of 
damage to them this spring. They should be planted in a more shel- 
tered place than the north side of the Forest Hills Road, and the dur- 
ation of the flowers would be lengthened if the trees could be sur- 
rounded by a belt of conifers. 
Diervilla florida. This Korean plant is one of the species which has 
played an important part in the evolution of the Diervillas or Weige- 
lias of gardens, and many of its hybrids and varieties have been prop- 
agated by nurserymen. The wild type of the species, if it is still cul- 
tivated in Europe, is a rare plant, and the Arboretum is fortunate in 
having raised plants from the seeds collected by Wilson during his 
recent journey in Korea. These are now flowering for the first time 
and their pure pink flowers promise to make it one of the most attract- 
ive of all the Diervillas. It has bloomed three or four days earlier 
than its variety venusta, another Korean plant, which until this spring 
has been the first Diervilla in the collection to flower. This variety 
has generally been considered here the handsomest of all Diervillas, but 
the flowers are not as pure pink as those of the type.
