Honeysuckle. It is a native of northern and central China and prom¬ 
ises to be a useful addition to summer fruiting shrubs. The fruits of 
two western American Bush Honeysuckles, L. involucrata and its vari¬ 
eties and L. Ledebourii ripen in July and are handsome and peculiar, 
for the large, lustrous black berries rise from the much enlarged 
bractlets of the flowers which are now bright red and much reflexed. 
One of the most interesting of these plants is the variety serotina of 
Lonicera involucrata. This has bright yellow flowers flushed with scar¬ 
let which do not open until July; the enlarged bractlets of this Colorado 
plant are spreading, not reflexed. 
The tree with the showiest fruits in the Arboretum in July is the 
Tartarian Maple ( Acer tataricum ) which is an early-flowering, very 
hardy small tree from southeastern Europe and western Asia. The 
wings of the fruit, which is now fully grown, are bright red and their 
beauty is heightened by the contrast of the dark green leaves. The 
female plants of the so-called Mountain Holly ( Nemopanthus mucro- 
nata) are handsome in July when their rose-red berrylike fruits are 
ripe. Nemopanthus, which belongs to the Holly Family, consists of 
a single species which is common in cool moist woods in the north¬ 
eastern United States and eastern Canada, and is a wide round-topped 
shrub with erect stems covered with gray bark, thin pale green leaves 
and inconspicuous flowers. It has taken kindly to cultivation in the 
Arboretum where there are a number of plants in the Holly Collection 
in the rear of the Horsechestnut Collection. The snow-white fruits of 
the red and yellow-flowered forms of the North American Cornus stol- 
onifera are now ripe. Very beautiful in winter from the bright col¬ 
oring of its stems and branches, this Cornel is equally beautiful in July 
and August when it is covered with its large and abundant clusters of 
fruit. A garden form of the Old World Cornus alba (var. Rosenthalii) 
is fruiting abundantly this year and promises to be a valuable addition 
to July and August fruiting shrubs. 
Some July Flowering Trees and Shrubs. Among the Lindens the 
last to flower are the small-leaved European Tilia cordata and its varie¬ 
ties. The handsomest of these is the var. cordifolia which differs from 
the type in its larger leaves and rather larger flowers. The Arboretum 
specimen is a shapely tree which this year when in flower has been more 
conspicuous than any Linden-tree in the Collection. The Japanese Cle- 
thra (C. barbinervis) is in flower about two weeks earlier than the native 
C. alnifolia. The Japanese species is a larger plant than C. alnifolia 
and in Massachusetts has grown ten or fifteen feet high and nearly as 
much through. The foliage is of a lighter green than that of the 
American plant; the flowers are less crowded in the racemes and lack 
the odor which makes C. alnifolia one of the most delightful of sum¬ 
mer-flowering shrubs. In the Arboretum plants of the Japanese 
Clethra have so far escaped the attacks of red spiders which often 
disfigure here those of C. alnifolia. 
Indigofera. Five species of this genus of the Pea Family are now 
blooming in the Arboretum. They are small plants with handsome 
flowers in terminal racemes, well suited to decorate a garden border. 
The three species with pink flowers, I. Kirilowii, a native of northern 
China, Manchuria and Korea, I. Potaninii and I. amblyantha are per¬ 
fectly hardy and the last will continue to open its small flowers on the
