those of the next species may remain on the bushes for some 

 time. This species is worth planting for its conspicuous red 

 stems, which are especially noticeal>le towards the end of 

 winter, as well as for the profusion of white Hovvers which it 

 l)ears in June. The silky Cornel (C sericea) does not gener- 

 ally ripen its fruit until the end of the month, and in some sit- 

 uations not until September. In the Arnold Ari)oretum and 

 vicinity the bright-blue fruit is produced in great abundance. 

 Corniis paniciilata, which is one of the most slender of the 

 natix'e shrubby species, bears a profusion of delicate white 

 Hovvers in June followed l.)y pale wliite fruit about the end of 

 August. 



If only one-fourth of the yellow early spring blossom of the 

 Cornelian Cherry {Corniis Mas) developed into ripe fruit, the 

 plant woidd again be a most Ijeautiful object from the middle 



small, slender-twigged, partly trailing shrub, from two to three 

 feet in height, with deep green leaves, one or twO' lines wide 

 and from one to two inches in length. 



The fruit ripens early in the month, when the piu'plish pods 

 open, disclosing the seeds enveloped in an orange-colored 

 aril. This little shrub is quite hardy at the Arboretum, and is 

 excellent in rockeries or for the borders of shrubberies. 



The smooth Sumach {Rhus glabra) throughout the month 

 bears velvety, crimson fruit, which is often collected for use 

 in making \'inegar or as a substitute for lime juice. It is not 

 such a tall growing species as the Staghorn Sumach, which, in 

 some respects, is to be preferred for planting in groups. 



The well-known Snowberry {^SympJioricarpiis raceutosus) 

 ripens some of its large, white berries during the month and 

 at the same time continues blossoming. Another plant with

to the end of August. The drupes are oblong, from three- 

 fourths of an inch to an inch long, and deep orange or bright 

 scarlet, or cornelian colored (whence the common name), 

 when fully ripe. They are edibl'e, though somewhat acid, and 

 in parts of Europe are made into marmalade and used in other 

 ways. Unfortunately, in this latitude, even large plants bear 

 very litde fruit, and it drops to the ground almost as soon as 

 matured. Corniis sanguinea is another European and Asiatic 

 species sometimes planted iii our gardens. It is a close, com- 

 pact shrul), which will grow eight or ten feet high, and it bears 

 small, terminal cymes of almost black, and not very orna- 

 mental, fruit. 



Enonyjiins nanus {E. angustifolius of some catalogues), a 

 native of the Caucasus, is the only species of the genus which 

 fully matures its fruit here during this month. This is a neat. 



the same habit of flowering is the Alder Buckthorn {Rhajunus 

 Frangula), which continues to produce its ripe, shining, pur- 

 ple-black and inconspicuous flowers from July until well into 

 the autumn. 



Except Rosa riigosa, which ripens first, Rosa Engebnanni, 

 recently described and figured in these pages (vol. 2, f. 121), 

 and Rosa acicidaris are the earliest species to become con- 

 spicuous with fruit in the Arboretum. The bright red fruit of 

 R. Engebnanni especially is large and attractive. 



Fruits of other species of roses also assume bright colors 

 during this month as well as some species and varieties of 

 Barberries. But as they are not always fully matured until 

 September, and remain on the plants for a considerable time, 

 they deserve mention later.
