pink flowers, and are of real value for the decoration of gardens. Other 
Honeysuckles now in bloom which should be noted are Lonicera bella, a 
large and vigorous hybrid of Lonicera Morrowii 'with the Tartarian 
Honeysuckle; Lonicera minutijiora, another hybrid, remarkable in the 
beauty of its brilliantly colored fruits; Lonicera notha, a hybrid of the 
Tartarian Honeysuckle with Lonicera Ruprechtiana of eastern Siberia; 
Lonicera minutijiora from central Asia; and another central Asia plant, 
Lonicera coerulea gracilijiora, a slender, although vigorous, shrub with 
beautiful drooping flowers. These are only a few of the large collec- 
tion of Bush Honeysuckles now in bloom. 
Among the Diervillas, or, as they are often called, Weigelas, natives of 
the eastern United States and of eastern Asia, a genus in which many 
hybrids and varieties have been developed in Japanese and European gar- 
dens, the earliest to flower in the Arboretum are two Asiatic species 
which can be seen in the Shrub Collection. The more beautiful of these 
two species is Diervilla jlorida, a small shrub, with pale pink flowers, in- 
troduced into the Arnold Arboretum a few years ago by Mr. Jack, from 
Korea. This plant has probably played a considerable part in the pro- 
duction of some of the hybrid races, but as a garden plant the wild type 
is more desirable than any of its progeny. The other species, Diervilla 
praecox, has larger flowers of a rather disagreeable purple tone. It is 
believed to be a native of Japan. 
On the curve of the Meadow Road beyond the Administration Building 
several plants of the pink-flowered Rhododendron (Azalea) canescens, 
the Azalea nudijlora , in part, of the old botanists, are coming into 
bloom. Plants of this beautiful native shrub can also be seen on Azalea 
Path. 
An illustrated guide to the Arboretum containing a map showing the 
position of the different groups of plants has recently been published. It 
will be found useful to persons unfamiliar with the position of the differ- 
ent groups of plants. Copies of this guide can be obtained at the Admin- 
istration Building in the Arboretum, from the Secretary of the Massa- 
chusetts Horticultural Society, 300 Massachusetts Avenue, Boston, from 
The Houghton, Mifflin Company, 4 Park Street, Boston, and at the Old 
Corner Bookstore, Bromfield Street, Boston. 
The Arboretum will be grateful for any publicity 
given these Bulletins.
