of the other Mountain Ashes in the collection. This tree is growing” 
with other species of Sorbus on the right-hand side of the path lead- 
ing into the Shrub Collection from the Forest Hills Gate. 
Berberis diaphana. In the early days of November no Barberry in 
the Arboretum equals this Chinese species in the brilliancy of its scar- 
let leaves. It is a low, broad, compact, round-topped shrub with small 
leaves which appear very late in the spring, usually solitary but large, 
pale yellow flow’ers and large oblong red fruits. The beauty, however, 
of this plant is chiefly found in its habit and in the color of the leaves 
in late autumn. There is a plant of this Barberry in the Shrub Col- 
lection and others in the supplementary Barberry Collection on Hickory 
Path near Centre Street. 
Crataegus Boyntonii. This small tree, which is a native of the 
Appalachian foothills from southwestern Virginia to Alabama, and one 
of the largest of the Intricatae Group, is well worth a place in collec- 
tions of these plants for the brilliant orange and red colors of the leaves 
at this time. It has large flowers in few-flowered clusters, yellow an- 
thers and nearly globose yellow-green fruit flushed with red which is 
still to be found on the plant in the Arboretum where it can be seen 
among the other Intricatae on the lov/er side of the road at the eastern 
base of Peter’s Hill. 
Crataegus Buckleyi. This is another arborescent species of the In- 
tricatae, which inhabits mountain slopes from two thousand to three 
thousand feet elevation from southwestern Virginia through western 
North Carolina to eastern Tennessee. It has flowers in more compact 
clusters than those of C. Boyntonii, rose-colored anthers, and sub-glo- 
bose, red or russet-red fruit. The leaves of this little tree turn as 
brilliantly as those of the last named species near which it is growing. 
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 Arboretum. Copies 
of this gpiide can be obtained at the Administration Building in the 
Arboretum, from the Secretary of the Massachusetts Horticultural 
Society, 300 Massachusetts Avenue, Boston, from The Houghton, 
Mifflin Company, 4 Park Street, Boston, and at the office of the Harvard 
Alumni Bulletin, 50 State Street, Boston. Price, 30 cents.
