The double pink flowers of this tree look like roses, and when it is in 
bloom excite the interest and admiration of visitors to the Arboretum. 
In the old collection, too, are plants of M. fusca, the only wild Apple 
tree in the Pacific states, and a plant of M. Dawsoniana, a hybrid 
between M. fusca and the common Apple which appeared many years 
ago in the Arboretum. The Crabapple to which the southern forests 
owe so much of their spring beauty, M. angustifolia, fortunately has 
proved hardy in, the Arboretum, and there are large specimens on 
Centre Street walk in the rear of the Hickories and in the Peter’s 
Hill Apple Group. It is the latest of the American species to flower, 
and the flowers are of a rather deeper pink than those of the other 
American species. In the Peter’s Hill Collection may be seen several 
plants of M. Soulardi, a tree which occurs occasionally over large 
areas in the Mississippi valley and is believed to be a natural hybrid 
between M. ioensis and the common cultivated Apple. 
Two Chinese Roses. For many years the Cinnamon Rose, Rosa cin- 
namomea, has been the first Rose in the Arboretum to open its flowers 
but this year two Chinese species are beginning to flower at the same 
time. These are R. Hugonis and R. omeiensis. The former has pale 
yellow single flowers about two and a half inches in diameter and is 
a tall, perfectly hardy free-flowering shrub with slender erect and 
spreading, pale brown stems and small pale leaves. There are not 
many yellow flowering Roses that are perfectly hardy and free-flower- 
ing in this climate and R. Hugonis is certainly one of the most valu- 
able single Roses which has lately been introduced into gardens. It is 
a native of western China and was first raised in England from seeds 
sent to the British Museum by the missionary for whom it has been 
named. There is a plant of this Rose in the Shrub Collection which 
will be in full bloom when this Bulletin reaches its Massachusetts 
readers. Rosa omeiensis is flowering in the Arboretum for the first 
time. It is a vigorous shrub with young stems covered with bright red 
prickles, and pure white fragrant flowers hardly more than an inch in 
diameter, borne singly at the ends of short lateral twigs, and bright red 
ellipsoidal fruits which are borne on stout, elongated, yellow, fleshy 
stalks, and are very showy. It is common on many of the mountain 
ranges of western China at elevations of from 6,000 to 11,000 feet above 
the sea, and sometimes grows twenty feet tall and forms great thick- 
kets. Its name is derived from that of one of the sacred mountains 
of China, Mt. Omei, where it is common. This Rose promises to be a 
valuable and distinct garden shrub in this climate, and its hardiness, 
vigor and stout stems armed with numerous straight spines suggest 
its value as a hedge plant. It will be found in the collection of Chi- 
nese shrubs on the southern slope of Bussey Hill with the other Roses 
raised from seeds collected by Wilson in western China. 
By an unfortunate typographical error on page 14 of the last issue 
of these Bulletins (No. 4) the flowers of the Lilacs Macrostachya and 
Gloire de Moulins were described as double white instead of pink, and 
the flowers of Madame Lemoine and Miss Ellen Willmott were described 
as pink instead of double white.
