332 THE NURSERY LIST. 



Viburnum. CaprifoliacecE. 



Seeds, which should be stratified. They usually remain 

 dormant the first year. Layers usually make the best 

 plants. Green cuttings made in summer and handled in 

 frames give excellent results. V. tomentosum ( V. plica- 

 turn of nurseries) is propagated by cuttings. Ripe cut- 

 tings are sometimes used for the soft-wooded species. 

 The snowball or guelder-rose ( V. Opulus) is rapidly in- 

 creased by layers. It is also a good stock for closely re- 

 lated species. V. Lantana and V. dentata are good stocks 

 on which varieties difficult to handle can be worked by 

 the veneer-graft during winter. 



Victoria (Royal Water Lily, Water Platter). Nymphaacea. 

 The seeds should be kept in vessels of water until time 

 for sowing, when they may be placed in loamy soil, and 

 the pot submerged a couple of inches in water, the tem- 

 perature of which should not be allowed to fall below "85. 

 The tank should be in a light position near the glass. 

 Annual. 



Vigna. Leguminosce. 



Seeds. The cow-pea or black-pea ( Vigna Sinensis) by 

 seeds when danger of frost is past. 



Vinca (Periwinkle, Running Myrtle). Apocynacecz. 



Increased by seeds, and (chiefly) by division. V. rosea 

 annually by seeds. 



Viola (Violet, Heartsease, Pansy). Violacece. 



The named violets are increased by cuttings made in a 

 cool house from vigorous shoots. Common species by 

 seeds, runners, and division of the plants. Pansies are 

 usually grown from seeds, but named varieties may be 

 multiplied late in the season from cuttings or from layers. 



Virgilia. See Cladrastis. 



Virginia Creeper. See Ampelopsis. 



Virgin's Bower. See Clematis. 



Viscum (Mistletoe). Lorantkacear. 



Raised from seed, which should be inserted in a notch 

 cut in the bark or under side of a branch of the host. 

 Avoid crushing the seed, and have the embryo directed 

 towards the trunk. To prevent birds from disturbing the 

 seeds after being placed in position, cover with light-col-
