Notes From the Arnold Arboretum 



In addition to the deciduous new Chinese Viburnums 

 enumerated in the last issue, the evergreen species new 

 to cultivation may now be here briefly described. 



The most striking is certainly Viburnum rhytidophyl- 

 him, a vigorous shrub with large handsome foliage and 

 large flower clusters. The sliort-stalked leaves are lance- 

 olate in outline, from three to seven inches long, nearly 

 entire at the margin, dark green and lustrous on the 

 much wrinkled upper surface and covered with a dense 

 yellowish tomentum beneath. The flowers appear in flat 

 clusters from three to six inclies in diameter and are fol- 

 lowed by dark crimson fruits. 



Viburnum utile is also a handsome species; it is a 

 slender-branched shrub with rather small foliage, re- 

 sembling that of certain species of Elaeagnus. The 

 short-stalked leaves are oblong or lance-oblong in outline, 

 obtuse or nearly so, entire at the margin, from one to 

 two inches long, dark green and lustrous on the upper 

 surface and whitish tomentose beneath. The flowers ap- 

 pear in rather small, but numerous clusters, they meas- 

 ure about two inches in diameter and are followed by 

 purplish black fruits. 



Viburnum cylindricum ( V. coriaceum) grows in its 

 native habitat into a small tree and its large foliage re- 

 sembles somewhat that of a green-leafed Aucuba. The 

 leaves are generally oblong, pointed, from three to six 

 inches long, entire or with a few large teeth, dark green 

 and lustrous on the upper surface, paler beneath and 

 quite glabrous. The pinkish white flowers are bell- 

 shaped, not flat as in most other species, one-fifth of an 

 inch long and disposed in dense clusters from three to 

 four inches in diameter and are followed by rather small 

 purplish black fruits. 



Nearly related and similar to the well-known Laurus- 

 tinus is Viburnum propinquum. The slender-stalked 

 three-nerved leaves are oval to oblong in outline, point- 

 ed, entire or often with a few small teeth, from one and 

 a half to three inches long, quite glabrous, dark green 

 and lustrous above and paler beneath. The insignifi- 

 cant greenish white flowers appear in rather small clus- 

 ters not exceeding three inches in diameter and are fol- 

 lowed by handsome, glossy and bluish black small 

 fruits. A closely related species, but much larger in 

 every part is Viburnum cinnamomifoliumj the leaves 

 attain a length of five inches and the loose clusters meas- 

 ure up to seven inches in diameter. From this the allied 

 Viburnum Davidi differs in the broader and shorter 

 thicker leaves and the denser and smaller corymbs. 



Of the genus Cornus which is very similar in habit 

 and appearance to Viburnum, though belonging to an 

 entirely different family, several new species have been 

 recently introduced from China; but none of them is 

 very striking. One of the most distinct is Cornus pau- 

 cinervis, a small shrub with small glossy foliage retain- 

 ing its dark green color until late in fall and white flow- 

 ers in small umbel-like clusters followed by black fruits. 

 The narrowly elliptic pointed leaves do not exceed three 



inches in length and are dark green on the upper sur- 

 face, lighter green beneath and glabrous. 



Some words may be said here about two much con- 

 fused species known since some time from Japan but 

 rarely cultivated which have been recently again intro- 

 duced from China. One of them is Cornus macrophylla 

 (C. brachypoda or C. corynostylis ) , one of the handsom- 

 est Cornels in cultivation, if we except the Flowering 

 Dogwoods, and growing into a small tree. The elliptic 

 leaves measure up to seven inches in length and are dark 

 green on the upper surface and whitish beneath. The 

 flowers are borne in large broadly pyramidal clusters 

 from four to six inches in diameter. This species has 

 opposite leaves like almost all Cornus, while the other 

 species which has • been called hitherto erroneously 0. 

 brachypoda or C. macrophylla has alternate leaves like 

 our native C. altemifolia and has been called in refer- 

 ence to the controversy which has arisen over its correct 

 name Cornus controversa. It is a handsome small tree 

 with slender-stalked broadly elliptic leaves attaining six 

 inches in length, bright green on the upper surface and 

 whitish beneath and with umbel-like clusters up to five 

 inches in diameter followed bv bluish black fruits. 



European Horticulture 



LAGERSTEOMIA INDICA KANA GLOBOSA 



The name given above is certainly a long one, but it 

 tells persons who know, what are the properties of the 

 plant; but in the trade, a shortening to Lagerstromia 

 nana is suiEcient. L. indica is rather tender in Eng- 

 land and Ireland and may not be left out of doors in the 

 winter season, excepting in the warmest localities. 'When 

 this plant in spring is planted out in a sunny place, and 

 the shoots and roots severely cut back it developes a 

 brilliant floral display in the course of the summer. The 

 variety nana globosa appeared among a number of seed- 

 lings of L. indica growing in the garden of Choba Tonbi 

 in the Crimea. It is distinguished by a dwarf, globose 

 habit, which features have remained constant, during 

 the twenty years that have elapsed since the date of its 

 appearance in the seed bed. The plant bloomed splen- 

 didly in 1908. The variety is worthy of a place in 

 mixed beds of flowering subjects ; and after the flower- 

 ing season is over, the leaves which at the time assume an 

 orange scarlet tint, have a striking effect for some weeks. 



chalk's early jewel tomato 



In Holstein this variety is much thought of, it being 

 equally fruitful under glass, as in the open ground. 

 The summer of 1908 was the most unfavorable that 

 could be imagined, and yet in favorable sheltered gar- 

 dens Chalk's Jewel ripened satisfactorily. It is one of 

 the earliest to ripen its fruits which are of globular 

 shape. The plant is of vigorous growth; and should 

 be grown with one stem only, fastened to a stout stake. 

 If a wall or close fence can be allotted to the plants 

 they need not be restricted to one stem.
