make travelling difficult. This plant has never really succeeded well 
in the Arboretum and is difficult to cultivate, although good plants 
may occasionally be seen in other Massachusetts gardens. There is 
now a small plant in flower among the dwarf Birches on the Bussey 
Hill Road opposite the Viburnum Collection. The Korean species, V. 
Carlesii, is rightly considered one of the handsomest plants recently 
introduced into American gardens. Its value is in the white, extremely 
fragrant flowers which are produced in rather small compact clusters 
and open from bright pink buds. As the flowers in a cluster do not 
all open at the same time the mixture of white flowers and pink buds 
adds greatly to the attractiveness of the inflorescence. It is a rather 
dwarf shrub of compact habit with pale green leaves and has not yet 
produced fruit in the Arboretum. There is a Japanese species, V. 
bitchuense, which somewhat resembles V. Carlesii, but the flowers 
are smaller and the habit of the plant is not so good. Mistaken by Jap- 
anese botanists for V. Carlesii, this plant has been propagated in Japan- 
ese nurseries and sent to the United States and Europe as V. Carlesii. 
In buying that plant care should be taken to secure the right species. 
A Possible New Hedge Plant. At Tachien-lu on the borders of 
Tibet, at about eight thousand feet above the sea, Mr. Wilson found 
hedges from 6 to 8 feet high and so thick and spiny that a yak, an 
animal as strong as an ox, could not break through them. The plant 
of which these hedges were made, Ribes alpestre, var. commune, is 
now in flower in the collection of Chinese shrubs on Bussey Hill. This 
Gooseberry has grown rapidly in the Arboretum and appears to be 
perfectly hardy. There is little to recommend it as a garden shrub 
for the flowers are small and inconspicuous, and the acid fruit is cov- 
ered with prickles and has little beauty, but as a hedge plant it may 
prove valuable in the cold parts of the country. 
Prinsepia sinensis. This Chinese shrub, which has been growing in 
the Arboretum since 1903, has proved itself to be a first-rate garden 
plant for regions as cold as New England. It is a plant with long and 
gracefully ascending and spreading branches, the bright green leaves 
are almost the first to appear in the whole collection, and when they 
are more than half-grown from their axils the bright yellow flowers, 
which are about two-thirds of an inch in diameter, appear in few-flow- 
ered clusters. The largest plant in the Arboretum is on Hickory Path 
near Centre Street, and there is a plant also in the general Shrub Col- 
lection. 
Automobiles are not admitted to the Arboretum, but visitors who 
desire carriages to meet them at the Forest Hills entrance can obtain 
them by telephoning to P. J. Brady, Jamaica 670, or to Malone & 
Keane, Jamaica 344.
