THE NURSERY-LIST 223 



Actinidia. Dttlenwcea. 



Propagated easily by seeds ; also by layers and cuttings. Hard- 

 wood cuttings should be put in sandy soil, in autumn ; cuttings of 

 half-ripened wood may be started in summer in a frame. Seeds 

 should be sown in spring. , 



Ada. Orchidacece. 



Handled by division when the plant begins to grow. See Orchids, 

 page 372. 



Adiantum (Maidenhair Fern). Polypodiacece. 



Propagation is by spores, using compost of half each finely 

 screened clean soil and leaf-mold or peat, placing in moderately 

 moist and shady spot in greenhouse in temperature of 60 F. The 

 sporelings will come along if the spores are sown in bunch pots with 

 a pane of glass over them and in a shady place. Also by divi- 

 sion of crown and rhizomes, in January or February. A. Farley ense, 

 being sterile, must be propagated by division, requiring a higher 

 temperature than other adiantums, 65 to 70 at night and 75 to 

 80 during the day. See Ferns, page 312. 



Adlumia (Allegheny Vine. Smoke Vine. Mountain Fringe). 



Fumariacece (or Papaveraccce) . 



Propagated by seeds in spring, sown in a damp cool place. The 

 plant is biennial, blooming the second season only. 



Adonis. Ranunculaceoe. 



Increased by seeds, sown in autumn or early spring. The peren- 

 nials may be root-divided in very early spring. 



^Echmea. Bromeliacece. 



Propagation as for billbergia, which see, page 252. 



Aerides. Orchidacece. 



The only method of propagating plants of this genus is by re- 

 moving the upper part and planting it separately. It should al- 

 ways be severed low enough to include a few roots, otherwise a large 

 proportion of leaves will be lost. A somewhat dense shade, a moist 

 atmosphere and careful watering are essential until the young plant 

 is established. The old stool will soon send out lateral growths, 

 which, in time, may be separated and treated similarly. Vanda, 

 saccolabium, angrsecum, renanthera, are increased in the same 

 way. See Orchids, page 372.
