It is not perhaps generally realized 

 that the fruit of several Honeysuckles 

 is more beautiful than their flowers, 

 and that among the species which are 

 bushes and not vines are plants per- 

 fectly suited to this northern climate 

 which are not surpassed in the abund- 

 ance and brilliancy of their fruits by 

 any plants which ripen their fruit in 

 summer. The Honeysuckles which 

 produce the earliest and the showiest 

 fruit are Lonicera tatarica and some 

 of its hybrids. The Tartarian Honey- 

 suckle, which is a native of western 

 Siberia and central Asia, is an old in- 

 habitant of gardens and one of the 

 best shrubs for cold countries, for it 

 can support without injury the exces- 

 sive cold of the long winter and the 

 burning sun of the short summer of 

 the north fatal to all but a few of the 

 plants which decorate the gardens of 

 more temperate regions. It cannot be 

 too often repeated that the Tartarian 

 Honeysuckle and its hybrids are large, 

 fast-growing plants, that they only 

 thrive in rich, well-drained soil, and 

 that they can only show their real 

 beauty when allowed sufficient space 

 for free development of their 

 branches. Twenty-five feet between 

 the plants does not give them too 

 much room. There are many varie- 

 ties of the Tartarian Honeysuckle in 

 the Arboretum collection varying in 

 color of their flowers and in the color 

 of their fruits. 



The varieties of L. tatarica which 

 have this year the handsome fruit are 

 the var. rosea with scarlet fruit and 

 var. lutea with bright yellow fruit. 

 The fruits, however, of some of the 

 hybrids are more beautiful than those 

 of any of the varieties of the species. 

 As fruiting plants the best of these 

 hybrids which are in the Arboretum 

 are Lonicera bella. L. muendeniensis, 

 L. notha, and L. amoena. L. bella was 

 raised in the Botanic Garden at Petro- 

 grad and is believed to be the product 

 of a cross between L. tatarica and the 



Japanese L. Morrowii. There are sev- 

 eral varieties of this hybrid differing 

 in the color of their flowers. They are 

 large, free-flowering plants with large, 

 lustrous red fruit. L. muendeniensis, 

 which originated in the Botanic Gar- 

 den at Muenden, is probably of the 

 same parentage as L. bella altered by 

 the cross with another species. It is 

 a very vigorous plant with large, lus- 

 trous, orange-red fruit. L. notha, 

 which is believed to be a hybrid of L. 

 tatarica and L. Ruprechtiana is an- 

 other large, vigorous, fast-growing 

 plant with lustrous orange-red fruit. 

 L. notha and L. muendeniensis as fruit 

 plants are the handsomest of the 

 large-growing Bush Honeysuckles with 

 dark green leaves and orange-red 

 fruits. More beautiful when in flower 

 is the hybrid of L. tatarica with the 

 Persian L. Korolkovii which is called 

 L amoena. This is a smaller plant 

 than the other hybrids of the Tarta- 

 rian Honeysuckle with pale gray-green 

 leaves, small pink flowers and small 

 red fruits. When it is in bloom this 

 plant is considered by many persons 

 the most beautiful Lonicera in the col- 

 lection. 



The Japanese L. Morrowii is more 

 beautiful now when it is covered with 

 its large orange-red fruits than it was 

 when the yellow and white flowers 

 were open in early spring. This is a 

 round-topped shrub, much broader 

 than high, with gray-green foliage, and 

 long lower branches which cling close 

 to the ground. When it can have suffi- 

 cient room in which to grow this is 

 one of the handsomest of the Honey- 

 suckles and one of the best shrubs in- 

 troduced into the United States by the 

 Arboretum. There are two hybrids of 

 this species in the collection, L. minu- 

 tiflora with small, translucent, yellow 

 fruit, and L. muscaviensis with large 

 bright scarlet fruit. They are large, 

 hardy and fast-growing plants. 



Very different are the bright blue 

 fruits of the different geographical 



forms of the widely distributed Loni- 

 cera coerulea which are now ripe. 

 These fruits are beautiful but they are 

 a good deal covered by the leaves, and 

 the plants are not as conspicuous at 

 this season of the year as the Tar- 

 tarian and several of the other Bush 

 Honeysuckles. The bright red fruit of 

 Lonicera trichosantha is conspicuous 

 in the last weeks of July. This is a 

 shrub now three or four feet tall in 

 the Arboretum, with erect stems, large 

 yellow and white flowers, and fruits 

 rather larger than those of the Tar- 

 tarian Honeysuckle. It is a native of 

 northern and central China and prom- 

 ises to be a useful addition to summer 

 fruiting shrubs. The fruits of two 

 western American Bush Honey- 

 suckles, L. involucrata and its vari- 

 eties and L. Ledebourii ripen in July 

 and are handsome and peculiar, for 

 the large, lustrous black berries rise 

 from the much enlarged bractlets of 

 the flowers which are now bright red 

 and much reflexed. One of the most 

 interesting of these plants is the va- 

 riety serotina of Lonicera involucrata. 

 This has bright yellow flowers flushed 

 with scarlet which do not open until 

 July; the enlarged bractlets of this 

 Colorado plant are spreading, not re- 

 flexed. 



The tree with the showiest fruits in 

 the Arboretum in July is the Tartarian 

 Maple (Acer tartaricum) which is an 

 early-flowering, very hardy small tree 

 from southeastern Europe and western 

 Asia. The wings of the fruit, which is 

 now fully grown, are bright red and 

 their beauty is heightened by the con- 

 trast of the dark green leaves. The 

 female plants of the so-called Moun- 

 tain Holly (Nemopanthus mucronata) 

 are handsome in July when their rose- 

 red berrylike fruits are ripe. Nemo- 

 panthus, which belongs to the Holly 

 Family, consists of a single species 

 which is common in cool moist woods 

 in the northeastern United States and 

 rn Canada, and is a wide round-
