8 ABIES HOMOLEPIS 



(,See Cover lllu8tratiou> 



One of the handsomest trees In the 

 Arboretum at this season Is the Jap- 

 anese Fir known as Abies homolepls 

 or brachyphylla. Professor Sargent, 

 director of the Arboretum, places this 

 tree as among the best which Japan 

 has sent to this country. It has 

 proved perfectly hardy in this climate, 

 not having suffered at all last winter. 

 In spite of the extremely low tempera- 

 ture. 



As it grows on the mountains of 

 Central Japan, it makes a very large 

 tree. Even in this country it attains 

 good size, as may be seen by inspec- 

 ting a specimen in the Hunnewell 

 pinetum at Wellesley, which is more 

 than fifty-five feet high, with branches 

 sweeping the ground. The trees in 

 the Arboretum are not as large, but 

 are growing well and are very hand- 

 some. 



Its dark green leaves are silvery- 

 white on the lower surface, and its 

 cones are violet purple In color. Ac- 

 cording to Professor Sargent, this is 

 one of the six most desirable conifers 

 for planting in Southern New Eng- 

 land, the others being Pinus strobus, 

 Pinus resinosa, Tsuga canadensis, 

 Tsuga carolinianum, and Abies con- 

 color. 



A variety of the Japanese fir, with 

 green cones and lighter colored leaves 

 Is established in the Arboretum, hav- 

 ing been grown from seeds planted In 

 1891. It Is called Abies brachyphylla 

 unbellata. 



CROWN GALL. 



The Stephenson mentioned in the 

 following letter has a rose growing 

 establishment at Oak Lane. Philadel- 

 phia, The warty nuts were woody 

 and hard and as big as hens' eggs 

 They appeared along the rose stems 

 and spread rapidly all over his crops. 

 One pound of formalin to twelve gal- 

 lons of water is said by the Austral- 

 ian Nurseryman to be a good steri- 

 lizer. After applying, cover the soil 

 with bags for two or three days.

• in lose Int.siic.s, hul it I'ccuis more fre- 

 quently in greenhouses than on out of 

 door plants. It is caused by the bacterial 

 organism c.illeil Bacterium Tumefaciens. 

 and the disease is usually designated as 

 crown gall. 



There is no satisfa<tory method for kill- 

 ing the galls after they have developed, 

 and great care must be taken not to spread 

 the disease. Those galls cut out should be 

 gurned : knives and implements used on 

 galled idants should be sterilized liefore 

 I'Utting healthy plants or digging around 

 them. Discard or sterilize the soil in which 

 galled plants have grown, if possible do not 

 nlant roses in it. Do- not make cuttings 

 from rose bushes with galls on either the 

 root or stem. 



In all probabilt.v the disease was carried 

 over to the Ophelia roses from the Aaron 

 Wards. 1 have been working for several 

 years witli this disease and find most hy- 

 bri<l roses susceptible to it. One grower 

 lost several houses from the rapid spread 

 of this disease. A very virulent strain of 

 the organism had gotten into his plants 

 and he did not realize the danger. 



The best plan, of course, is to discard 

 those plants with galls and the soil they 

 grew in. If this is too drastic or not 

 practicable at the time, cut off the stems 

 well below the galls and burn them, and be 

 careful not to use your knife on a healthy 

 plant without first immersing it for some 

 time in a good germicide. Those plants 

 with galls at the root or crown are too 

 dangerous to keep and should be burned 

 without making cuttings from them.
