tibetica from western China and Thibet, a low plant with slender spread- 
ing branches, and Lonicera Ledebourii from California. 
Nearly all the plants of the Elaeagnus Family retain their leaves until 
late in the autumn, but the only one in the collection which is still as 
green as at midsummer is the Sea Buckthorn, Hippophae rhamnoides, a 
widely distributed shrub or small tree of Europe and central Asia. The 
male and female flowers are produced by different individuals and the 
female plant is attractive when the branches are covered with orange- 
colored persistent fruits. Tall treelike plants of the Sea Buckthorn can 
be found with the other plants of this Family on the left-hand side of 
Bussey Hill Road just above the Lilac Collection. 
Several European yellow-flowered plants of the Pea Family are now 
conspicuous from the bright green color of their leaves. Some of the 
most beautiful autumn plants among them are Genista germanica , Gen- 
ista pilosa, Genista tinctoria, Genista elata, Cytisus nigricans , and 
Cytisus capitatus. These are all small low shrubs well suited for small 
gardens. They can be found in the Shrub Collection. Another yellow- 
flowered plant of this Family, Coronilla Emurus, of southeastern Europe, 
grows to a larger size but it is equally green in the first week of Novem- 
ber. There are good specimens of this rather tender shrub on the right- 
hand side of Azalea Path. 
The leaves of few American plants retain their summer color until 
November. An exception, however, is Leucothoe racemosa from the 
southern Appalachian Mountains which can be seen in the Shrub Collec- 
tion. A very different plant but one still as green is the Chinese Matri- 
mony Vine, Lycium chinense. This has long, wand-like, arching or 
prostrate stems which with a little support can be made vine-like and 
used to cover trellises. It is a useful plant for draping walls and when 
planted as a shrub in masses it soon makes an impenetrable barrier. The 
scarlet shining fruits which are abundantly strung along the branches 
add greatly to the autumn beauty of this hardy plant. It has been freely 
used to cover the boundary walls of the Arboretum and it can also be 
seen in the Shrub Collection. 
In the group of Barberries on Hickory Path and in the Shrub Collection 
is a plant which is still but little known in American gardens. This is 
Berberis Neubertii , a hybrid between the common Barberry, Berberis 
vulgaris , and the evergreen Berberis or Mahonia Aquifolium. It is a 
moderate-sized, broad-topped shrub with large dark green leaves which 
remain on the branches with little change of color through November. 
This plant does not bloom freely and rarely produces fruit, but it is one 
of the hardiest and handsomest of the shrubs with semi-persistent foli- 
age which have been introduced into the Arboretum. 
The leaves of a few vines are still almost as green as in summer and 
promise to remain green for sometime longer. The best known of these, 
perhaps, is a Japanese Honeysuckle, a form of Lonicera japonica, which 
is usually known in gardens as Hall's Honeysuckle. In the middle and 
southern states this vigorous plant has become perfectly naturalized, 
often crowding out the native plants, and retains its foliage during the 
winter. Here the leaves are killed by severe cold. As a flowering plant, 
too, this is one of the handsomest of the Vine Honeysuckles which are 
hardy in this climate.
