270 PROPAGATION OF PLANTS. 



rather large unless kept well cut back. Propagated by seeds and 

 cuttings. 



Datura (Stramonium). A genus of shrubs, trees and annuals. A 

 few of the species, like D. Arborca (or Jtrugmansia Candida of some 

 authors), and D. mctdoidcs from California, are cultivated for their large 

 tube-shaped flowers or showy foliage. Propagated by seed ; and the 

 shrubby species and varieties by cuttings, which strike root quite 

 readily under glass. 



Decumaria. A handsome climbing shrub, -with white, sweet- 

 scented flowers. Indigenous to the Carolina s and Florida. Eeadily 

 propagated by layers and cuttings. The latter should be made in sum- 

 mer, and planted in the shade, and given plenty of water. 



Desfontatnea. A Holly-like, evergreen shrub, native of the 

 mountains of Chili. Said to be hardy in England. Propagated by 

 cuttings, planted either in li^ht loam or sand under glass. 



Dsutzia. Well-known, hardy, dreciduous shrubs of easy culture. 

 Propagated by cuttings of the mature shoots of the season, made in the 

 autumn and stored in a cool and moist place ; planted out in spring. 

 For the slender-growing, dwarf species, like the D. tjracilis, green cut- 

 tings are preferable, taken from plants forced under glass in winter. 

 These green cuttings should be taken off with a heel, or close to the 

 old stem, and then set in close frames ; they will strike root in a very 

 few days. 



Diervilla (Weigela). A genus of hardy, deciduous shrubs, with 

 showy, funnel-shaped flowers, varying in color from pure white and 

 yellow to deep rosy purple. The Chinese and Japanese species and 

 their varieties are far move common in cul ivation than our two indig- 

 enous species, viz., D. trifida and D. scssiliflom. Propagated very 

 readily by either ripe wood cuttings in the open air, or green wood 

 under glass. 



Dlmorphanthus. See Aralia. 



El(eagnus (Oleaster, Wild Olive). A small genus of evergreen 

 and deciduous shrubs. One species, the E. argentca, is a native, and 

 sometiniss cultivated ; also one or two species from Europe and Japan. 

 Propagated by seed, layers and root-cuttings. 



Ellloitia. A genus of only three species, one indigenous to our 

 Southern States, and two are found in Japan. The first is a deciduous 

 slirub, growing four to ten feet high, bearing small, white flowers in 

 terminal racemes, resembling those of the Andromeda. Propagated by 

 soft wood cuttings under glass. 



Epacris. Small evergreen shrubs and trees, mostly from the Indian 

 Archipelago, Australia and Polynesia. All are tender, and require the 

 protection of a warm greenhouse in winter, but may be planted out in 

 summer. They are highly valued for the great number of flowers which 

 appear during the winter months. Pteadily propagated by cuttings of
