Summer Flowering Trees. Several trees with handsome or interest¬ 
ing flowers bloom in the Arboretum in July and August. All these 
and many summer flowering shrubs should find a place in gardens 
which are chiefly used during July, August and September, that is in 
many northern seashore gardens. The most important of summer 
flowering trees here are the Lindens. Some of the species begin to 
flower about the middle of June, but in the Arboretum collection are 
Linden trees which are covered until the end of July with their beau¬ 
tiful fragrant flowers beloved of bees. In the meadow on the right- 
hand side of the Meadow Road there is a large collection of these 
trees with many species, hybrids and varieties. Among them are trees 
of great beauty of habit, and trees which can be successfully used in 
New England to shade streets and roads and to decorate parks. A care¬ 
ful study of the Linden collection in the Arboretum during June and 
July will repay lovers and planters of trees. 
Koelreuteria pamculata. This Chinese tree will be in bloom when 
this number of the Bulletin reaches its readers. It can be seen on the 
right-hand side of the Meadow Road beyond the Evonymus Collection. 
Koelreuteria is a medium-sized tree with large, dark green compound 
leaves and large erect clusters of bright yellow flowers which are fol¬ 
lowed by conspicuous bladder-like fruits. This tree is now often 
planted in this country, especially in the middle states. In nursery 
catalogues it often appears as “The Japanese Lacquer-Tree,” an 
absurd name, for it is not a Japanese tree and it does not produce 
lacquer.
