IMPORTANT NEW OR RARE TREES 

 AND SHRUBS. 

 The report of Joliii Dunbar, of Roch- 

 ester. N'. Y. I'arks, as Itolanist of the 

 S. A. F. which Is piibllshotl In full In 

 the annual publication of that society. 

 Is so very important and interesting 

 that we should like to present it entire 

 in these columns. Limits of available 

 space preventing us from so doing, we 

 herewith give some extracts which 

 many of our readers not having the 

 S. A. F. report will no doubt be 

 pleased to know. Mr. Dunbar is ex- 

 ceptionally well informed and qualified 

 to speak on these things which ought 

 to be better known to the gardening 

 profession. There are only two places 

 In this country where such informa- 

 tion can be obtained, — the Arnold Ar- 

 boretum and the Rochester Parks. 



Juniperus Chinensis, variety Sar- 

 gent!, was introduced from Japan by 

 Dr. C. S. Sargent 25 years since, and 

 we believe it is destined to be one of 

 the best trailing Junipers for decora- 

 tive planting In the northeastern 

 States. The habit is perfectly pros- 

 trate, and the long stems hug the 

 ground closely. The color of the fo- 

 liage varies from olive green to bluish 

 green. Juniperus Chinensis columna- 

 ris is a remarkably beautiful form of 

 the Chinese Juniper. The habit Is 

 dense and strictly columnar, and the 

 leaves are all acicular and bright 

 green. 



Juniperus littoralis Is a new Juniper, 

 introduced from Japan in 1914 by Mr. 

 E. H. Wilson. He found it growing on 

 the sea coast of Japan, with the habit 

 always prostrate in exposed, sand/ sit- 

 uations. The young plants in our pos- 

 session are growing with remarkable 

 vigor. Of course, it may be too soon 

 to express an opinion about it, but Mr. 

 Wilson says of it, "This species ought 

 to be perfectly hardy in eastern North 

 America, and if it thrives should make 

 a good ground cover and be especially 

 valuable for covering sand dunes." 



Magnolia Andre Leroy belongs to 

 the group of Chinese hybrid Magno- 

 lias which had their origin by crossing 

 Magnolia denudata with Magnolia lili- 

 flora. Magnolia Andre Leroy came 

 here from Holland a number of years 

 ago, and we have never seen it any- 

 where else. It has remarkably large 

 cup-shaped flowers. 7-9 inches across 

 when fully open, rosy red outside, and 

 cream-white inside. The blossoms are 

 similar in formation to Magnolia Len- 

 nei. It is one of the most distinctive 

 of the reddish-colored Magnolias. 



Magnolia Brozzonii is another of the 

 Chinese hybrids which, as tar as we 

 are aware. Is very rare in parks and 

 gardens. The blossoms are tubular in 

 outline before they expand. The flow- 

 ers are white in effect at a distance, 

 but they are tinged on the outside 

 towards the base with lilac-pink. They 

 are almost pure white or cream-white 

 inside; when the flowers fully expand 

 and before they drop they are G-8 

 Inches across. This is one of the most 

 showy of all the Magnolias. 



Magnolia rustica flore rubra is an- 

 other of the rare Chinese hybrids, and 

 a remarkably good grower; it is dis- 

 tinguished by bright purple-red on the 

 outside of the blossoms. The suffu- 

 sion of red is perhaps more percep- 

 tible in this Magnolia than in any oth- 

 er. The flowers are about 6 inches 

 across when fully open. In "Flora 



LORRAINE BEGONIAS. 



It is not too late yet to make a late 

 batch of Lorraine cuttings for flower- 

 ing in small pots. These sell readily 

 for table adornment and for use in 

 Christmas combination pans or jardin- 

 ieres. Cuttings are best started in 

 finely sifted sand. Little plants in 



and Sylva." \"ol. I, p. 17. .Mr. Wezlcn- 

 burg, of Hazerswoode Nurseries, Ley- 

 don, Holland, states "We found this 

 Magnolia growing in the nursery of 

 a friend in Boskoop, and we bought it 

 from him. It had no name. In con- 

 ference with this gentleman we agreed 

 to call it rustica flore rubra. He told 

 me it came up in a batch of seedlings, 

 but he did not know their origin." 



Magnolia Verbanica came to us 

 from Holland, and has flowered freely 

 for a good many years, and belongs to 

 the Chinese hybrids. We have not 

 seen it elsewhere. This is, perhaps, 

 the nearest approach to a pink flow- 

 ered Magnolia, as the blossoms are 

 deep rosy pink on the outside and 

 blush-white inside. The flowers when 

 fully expanded are about 7% inches 

 across. 



Magnolia salicifolia is a species 

 from Japan and was. I believe, intro- 

 duced from there by Dr. C. S. Sargent, 

 and has not been very many years in 

 cultivation. It flowered in the Roches- 

 ter parks for the first time last Spring. 

 It comes into bloom about the same 

 time as Magnolia stellata. The leaves 

 are ovate-lanceolate, light green above, 

 glaucescent beneath, and 4-6 inches 

 long. The flowers are white, or cream 

 white, and 4 to 4V2 inches across, and 

 are borne on short stalks. The stem 

 Is covered with smooth, greyish bark. 

 It is not as showy as any of the 

 Chinese hybrid Magnolias, but it is in- 

 teresting on account of its early 

 flowering. It is distinctive from all 

 other Magnolias in Its almost fastigi- 

 ate branching habit. 



Ilamamelis vernalis. This Is an in- 

 teresting species of Witch Hazel dis- 

 covered a few years ago in southern 

 Missouri, and has been found in 



their first pots must not be permitted 

 to become pot-bound. As they grow 

 keep them stocky by frequent pinch- 

 ing back and give some shade from 

 the hot sun from now on. Watch out 

 for sreen fly. Now is the season for 

 rapid growth before the weather gets 

 too hot. 



Arkansas and Louisiana. The petals 

 are yellowish, with a wine-colored 

 calyx on the inside. As it flowers in 

 mid-Winter, late Winter, and early. 

 Spring this new species is very inter- 

 esting. 



Rosa Fedschenkoana. This Rose is 

 a native of Turkestan, and has arch- 

 ing stems and leaves with 7-9 leaflets. 

 The flowers are usually 2-4, pure 

 white, and 2 to 2V2 inches across, and 

 have a very pretty effect in bloom. 



Rosa Hugonis is, perhaps, the most 

 important hardy species that has been 

 introduced to gardens in a good many 

 years. The branches are ascending 

 and partly spreading. The stems have 

 numerous prickles mixed with bristles, 

 and the leaves have usually 7-11 leaf- 

 lets. The pure yellow flowers, 2V4 

 inches across, are solitary, and borne 

 on short pedicels % to % of an inch 

 long. They are produced in great 

 abundatice, and a well developed in- 

 dividual gives a remarkably beautiful 

 effect. It is among the earliest of all 

 Roses to bloom. 



Rosa Jackii belongs to the multiflora 

 group, has a spreading habit, and 

 forms a round dense mass. The leaves 

 have 7-9 leaflets, deep lustrous green. 

 The flowers are borne in corsmibose 

 clusters, pure white, and are about 1% 

 inches across. 



Rosa Moyesil is said to attain a 

 height of 10 feet. The branches are 

 ascending and spreading, and have 

 short prickles. The leaves have 7-13 

 leaflets. The blossoms are commonly 

 1-2, on short stalks, are about 2% in- 

 ches across, and in our plants are dark 

 red. but they are said to vary to light 

 pink.

 Interesting discovery by Mr. Wilson in
