gi-ows well in comparatively dense 

 shade. 



Viburnum bracteatum is the rarest of 

 American Viburnums, being known to 

 grow naturally only on the cliffs of the 

 Coosa river, near Rome, Georgia, 

 where it is a tall shrub with numerous 

 slender stems. A plant of the form of 

 Yihurnitm pubescens from southern Mis- 

 souri and Arkansas has sometimes 

 been called V. afpne. Another exceed- 

 ingly rare species is T. molle, from 

 southern Kentucky and southern Mis- 

 souri, with large, nearly round thick 

 leaves on long stems. 



Tiburiium americaniim is one of the 

 species with palmately lobed leaves, 

 flat-flower clusters surrounded by a 

 ring of showy white ray flowers, and 

 red fruits; it is a tall broad shrub 

 common in northern woods and particu- 

 larly ornamental late in the autumn 

 when the leaves turn yellow and 

 orange color and the brilliant trans- 

 lucent fruits, which sometimes remain 

 on the plants through the winter, are 

 very conspicuous. Two other species 

 of this particular group flower are V. 

 Opiilns and V. Hargentii. The former 

 is a native of northern Europe and Si- 

 beria; the flower-clusters are smaller 

 than those of the American species but 

 it is a larger and handsomer shrub 

 with thicker and darker green leaves 

 which fall later in the autumn, and 

 rather larger, darker colored fruit. 

 There is a variety of this plant with 

 yellow fruit (var. raiitliocarpum); an- 

 other variety is a low. dense little 

 bush (var. iwtinm) which very seldom 

 flowers. The old-fashioned Snowball 

 or Guelder Rose is a variety of T. 

 Opuliis with all flowers sterile. V. 

 Sargvntii is a common shrub in north- 

 eastern Asia and when it is in flower 

 it is the handsomest of these three 

 species, for the ray flowers are larger 

 than those of the American or the Eu- 

 ropean plant. The dark green leaves 

 with the long, narrow terminal lobes 

 are interesting, but the fruit of this 

 plant is comparatively small, dull-col- 

 ored, and much less attractive than 

 that of the other species. 



Viburnum cassinoides is now in flow- 

 er. By many persons this tall shrub of 

 northern swamps and swamp borders 

 is considered the handsomest of the 

 American Viburnums. In cultivation 

 it is a rather low, broad plant. The 

 leaves, which vary greatly in shape 

 and size on different individuals, are 

 thick and dark green; the flowers are 

 creamj' white and are arranged in 

 large or small convex clusters and are 

 followed by drooping fruits which, 

 when fully grown, at first green, grad- 

 ually turn flesh color or pink and 

 finally dark blue, and are covered 

 with a glaucous bloom, the fruit of the 

 different colors sometimes appearing 

 together in the same cluster. This 

 plant takes kindly to cultivation and 

 has been largely planted in the road- 

 side shrubberies. The southern rela- 

 tive of r. cdssuioides, V. ii'nUim, has 

 never become established in the Ar- 

 boretum, although as it grows at high 

 altitudes on the Appalachian Moun- 

 tains it should prove hardy in New 

 England. 



Three blue-fruited American Vi- 

 burnums, V. (lentatum. V. vcnosum and 

 y. Canbyi, will not be in bloom for 

 some time, the latest of them, V. 

 Canbyi, carrying the flowering of these 

 plants to midsummer, so that the 



flowers of American Viburnums can be 

 seen in the Arboretum from the mid- 

 dle of May to the middle of July. 



An illustrated guide to the Arboretum 

 containing a map showing the position of 

 the different groups of plants has recently 

 been published. It will he found useful to 

 persons unfamiliar with the position of the 

 different groups of plants. Copies of this 

 guide can be obtained at the Administra- 

 tion Building in the Arboretum, from the

ROYAL HORTICULTURAL SOCIE- 

 TY SPRING SHOW. 



iVontitiued from parje S93) 

 Roses and Carnations. 



Much attention was attracted to 

 Mdme. Edouard Heriot, the best seed- 

 ling rose at the International Show. 

 This is one of the introductions of 

 Mons. Pernet-Ducher, and was exhib- 

 ited by Beckwith & Son, of Hoddes- 

 don, who also showed a new hybrid 

 tea, Willowmere, after the style of the 

 popular Lyon rose. Alexander Dick- 

 son & Sons showed Irish Fireflame, and 

 Mrs. Campbell Hall, a new tea, cream, 

 suffused with flesh pink. The two last 

 named received awards of merit. Wm. 

 Paul & Son had a very effective rose 

 group, showing amongst others a white 

 sport from Tausendschon. St. Helena 

 is a new H. T., which was included in 

 the group of Benjamin R. Cant & 

 Sons, of Colchester. This handsome 

 bloom is creamy with a pink blush in 

 the centre, and tinged with yellow at 

 the base of the petals. Carnations 

 formed an interesting section. Mary 

 Allwood, by Allwood Bros., is a shape- 

 ly bloom, cherry salmon, somewhat 

 similar to Lady Hermione, the well- 

 known border variety. White Wonder, 

 Empire Day and May Day were among 

 the other newer kinds skown in the 

 group. A. F. Dutton had a distinctive 

 variety in Mrs. A. F. Dutton, apple 

 blossom tint. 



Some Other Features. 



Sweet peas were not a very exten- 

 sive section. The trade exhibitors will 

 be making a big display at the show 

 of the National Sweet Pea Society In 

 July. E. W. King & Co., of Coggle- 

 shall, Essex, had a new maroon sweet 

 pea. Anglian Royalty. Dazzling splashes 

 of color were furnished by the May- 

 flowering tulip groups. Particularly 

 striking was a group arranged by R. 

 H. Bath, Ltd.. of Wisbech, a very suc- 

 cessful bulb-growing centre. Notice- 

 able in the collection was a Darwin 

 variety, Massenet, which secured a 

 special award at a recent meeting of 

 the R. H. S. A splendid collection of 

 hardy rhododendrons was staged by J. 

 Waterer & Sons, of Bagshot, Surrey, 

 who once more demonstrated the high 

 standard to which they have brought 

 the cultivation of these showy sub- 

 jects. A very comprehensive and 

 meritorious collection of ferns was ar- 

 ranged by H. B. May & Sons, of Upper 

 Edmonton. The flrm received a flrst- 

 class certiflcate for Nephrolepis exal- 

 tata Willmottae. With the vivid array 

 of gorgeous coloring in the begonias of 

 Blackmore & Langdon, Bath; the aza- 

 leas of Cuthbert & Co., Southgate; 

 the delphiniums of Kelway & Son, of 

 Langport, and the hippeastrums of 



Ker & Sons, Liverpool, the show 

 lacked nothing in the way of variety 

 and completeness. In the fruit depart- 

 ment, Laxton Bros., of Bedford, 

 showed some delicious strawberries. 

 King George V. is a new forcing va- 

 riety. T. Rivers & Son, Sawbridge- 

 worth, demonstrated the efficiency of 

 their system of training fruit trees in 

 pots. Some 80 varieties of apples 

 were shown by George Bunyard & Co., 

 of Maidstone. The outdoor displays 

 were in keeping with the high stand- 

 ard which prevailed throughout the 

 show. The art of constructing a rock 

 garden, with its countless little plants 

 nestling in the crevices was effective- 

 ly shown by some of the leading spe- 

 cialists in this particular line. There 

 were also some formal gardens of ex- 

 cellent design, replete with objects of 

 Interest. W. H. Adsett. 



THE REGAL MOUNTAIN LAUREL. 



The delightful visit, last year, to the 

 laurel hills of northern Massachusetts 

 by a party of Boston horticulturists 

 was repeated on Wednesday of this 

 week and, as before, as guests of H. 

 Huebner of Groton. Mr. Huebner met 

 his friends at Aver and the forty-mile 

 auto ride through a most charming 

 and picturesque country was a most 

 enjoyable experience. Words fall to 

 do justice to those kalmia-clad hills of 

 Ashby and no picture could adequately 

 suggest the sensations one feels when 

 gazing on the resplendent beauty of 

 those billows upon billows of rosy pink 

 and white. The present season is an 

 exceptional one in the profusion of 

 bloom and the show was simply over- 

 powering in its sublimity. The party 

 stopped on the way to look at the 

 patch of Scotch heather growing wild 

 in Townsend. On the return Mr. 

 Huebner's greenhouses and nurseries 

 were inspected and many interesting 

 evidences of cultural ability were 

 noted, not the least among which were 

 the young stock of winter-flowering 

 snapdragons originated by Mr. Hueb- 

 ner and on which he has been working 

 for years to obtain and fix the most 

 desirable colors. It goes without say- 

 ing that hospitality was unlimited and 

 the event will live long in memory as 

 one of rare enjoyment for those who 

 participated. 



The Federal Horticultural Board has 

 issued a circular giving information 

 regarding foreign inspection and mak- 

 ing requirements under the Plant 

 Quarantine Act substantially as pre- 

 pared by the Department of Agricul- 

 ture and transmitted through the De- 

 partment of State under date of Feb- 

 ruary 7, to the diplomatic officers of 

 the United States for transmission by 

 them to the governments to which they 

 were respectively accredited. It is now 

 reprinted for tlie information of im- 

 porters of nursery stock, more partic- 

 ularly to call attention to the exact 

 requirements as to foreign inspection 

 and certification, and to give the proper 

 forms of the certificates which must 

 accompany nursery stock and also to 

 indicate the proper marking or label- 

 ing of each package or other container 

 as a condition of entry. The law goes 

 into effect on and after July 1, 1913.

 man, Federal Horticultural Board,
