Typha (Bullrush, Cat's Tail, Reed Mace;. Typhacece. 



Propagation may be effected by seeds sown in a pot 

 plunged in water nearly to the level of the soil ; or by 

 divisions. 



Ulex (Furze, Gorse, Whin). Leguminosce. 



Propagated by seeds or by cuttings. 

 Ulmus (Elm). Urticacece. 



Usually propagated by stratified seeds. Layers are some- 

 times made, and suckers may be taken. The varieties are 

 grafted on common stocks. 



Unicorn Plant. See Martynia. 

 IJvularia, including Oakesia (Bellwort). Liliacece. 

 Seeds ; usually by divisions. 



Vaccinium (Swamp Huckleberry, Whortleberry, Blueberry, 



Bilberry, Cranberry). Vacdniacece. 



Seeds, layers, root cuttings, and divisions of the old plants, 

 Some species by hard-wood cuttings, for which see Cran- 

 berry. Huckleberry seeds are small and somewhat difficult 

 to grow. The seeds should be washed from the fruits and 

 stored in sand in a cool place until late in winter. They are 

 then sown in pans or flats on the surface of a soil made of 

 equal parts sand and loam. Cover with fine sphagnum and 

 keep in a cool house or frame, always keeping the seeds moist. 

 Seeds treated in this way may be expected to germinate in a 

 month or two, although they may lie dormant a year. Trans- 

 plant frequently and keep shaded until large enough to shift 

 for themselves. Layers should be tongued. Cuttings, two 

 or three inches long, of the best roots, made in fall and 

 placed in mild bottom heat in early spring, often give fair 

 satisfaction. Native plants can be obtained frcm the woods 

 and fields which will give good satisfaction if small speci- 

 mens are taken. 



Valeriana (Valerian). Valerianece. 



Seeds and divisions. 

 Vallota. Amaryllidece. 



Bulbels, which usually appear above the surface of the 

 pot. Division of the bulbs. 



Vanda. Orchidece. 



The majority are propagated in the same way as described 

 for aerides, but two species V. teres and V. Hookeri both
