nine inches wide, and the cup-shaped creamy white fragrant flowers 
are sometimes a foot in diameter. Although an inhabitant of the 
south, M. macrophylla is perfectly hardy in New England, but unless 
it is planted in sheltered positions the trees often become disfigured 
by the wind which tears the large delicate leaves. Less showy M. glauca 
is a more valuable plant for general cultivation. Often a large tree 
in the extreme south, at the north M. glauca is never more than a small 
tree, or more often a large shrub. The leaves are dark green and 
very lustrous on the upper surface and silvery white on the lower sur- 
face; the small, cup-shaped flowers are creamy white and delightfully 
fragrant, and they continue to open in succession from the middle of 
June until August. In all North America there is not a more delight- 
ful shrub to plant in the garden, or one that will give larger returns 
in beauty and fragrance; and yet it is difficult to find it in American 
nurseries, and it is unknown to most American planters of this gener- 
ation. A hybrid, M. Thompsoniana ;, between M. glauca and M. tri- 
petala, another American species, is a handsome plant with the gen- 
eral appearance of M. glauca but with larger leaves and larger, equally 
fragrant flowers. This plant is with the American Magnolias on the 
right-hand side of the Jamaica Plain Gate and is now in flower. Un- 
fortunately it is much less hardy than either of its parents. 
On Hickory Path near Centre Street there is a group of large plants 
of Styrax japoniea now covered with their pure white cup-shaped 
flowers hanging gracefully down from the branches on long slender 
stems; this is one of the handsome flowering shrubs of Japan, but un- 
less a sheltered position can be provided for it, it is not perfectly hardy 
in the neighborhood of Boston. That it is perfectly at home, where 
it is now planted in the Arboretum, is shown by the great crops of 
seedlings which spring up every year under the old plants. 
Near this group of Styrax japoniea are two species of Indigofera, 
I. Kirilowii and I. amblyantha, now in flower. The former is a 
native of Korea and is a low leafy plant which spreads into a broad 
mass and continues to produce its racemes of large pure pink flowers 
during several weeks. It was introduced a few years ago into the 
Arboretum by Mr. Jack, and is an exceedingly valuable garden plant. 
There is a specimen also of this species in the Shrub Collection. I. 
amblyantha is of entirely different habit, with slender erect stems, 
small leaves, and erect axillary clusters of small rose-colored flowers 
which continue to appear during two or three months. An inhabitant 
of river cliffs in Hupeh at altitudes up to six thousand feet, it some- 
times grows there to the height of six feet. This plant flowered in 
the Arboretum last year for the first time. It appears to be perfectly 
hardy, and it is one of the most beautiful of the small shrubs intro- 
duced by Wilson from western China. Two other species of this genus 
are established on Azalea Path near its entrance from the Bussey Hill 
Road, I. Gerardiana , a native of the Himalayas, and I. decora from 
southern China. These two plants, although they are killed back to 
the ground every winter, send up new stems and flower profusely 
every year. I. decora with its large white flowers is a beautiful little 
plant well worth knowing; it is just coming into bloom. 
In the Shrub Collection one of the Roses discovered by Wilson on 
the mountains of Hupeh, Rosa setipoda, is now in flower; it is a large 
vigorous shrub with broad, many-flowered clusters of long-stalked, 
dark pink flowers. This Rose proves to be very hardy and promises 
to be a decorative plant of much value.
