THE NURSERY-LIST 231 



Angiopteris. Marattiacece. 



Propagation by fleshy scales at base of each frond. These scales 

 should be placed on sand and covered with sphagnum. Also by 

 division. See Ferns, page 312. 



Angraecum. Orchidacece. 



Propagation as for aerides, which see. 



Anguloa. Orchidacece. 



Propagated by dividing the pseudobulbs, just before they be- 

 gin to grow. Division must be made after the shoots are dis- 

 tinguishable from the old back bulbs : these old bulbs are removed 

 at the creeping rhizome or rootstock. See Orchids, page 372. 



Anise (Pimpinella Anisum). Umbelliferce. 



Increased by seeds sown in the garden in spring on approach of 

 warm weather. 



Annona (Custard-Apple). Annonaceas. 



Increased by seeds, which, in the North, should be sown in pots 

 in a hotbed ; by ripened cuttings, which will root in sand under 

 glass, in bottom heat. Highly valued species are propagated by 

 budding and grafting, shield-budding being most commonly em- 

 ployed after the method of handling the orange. The bud should 

 be taken from wood from which the leaves have fallen, preferably 

 about one year old. On older stocks, cleft-grafting may be em- 

 ployed, using well-matured cions from which the leaves have 

 dropped. The stocks are usually the cherimoyer (A Cherimola) 

 or the pond-apple (^4. glabra), grown from seeds. 



Annuals. 



The subjects known to gardeners as " annuals " are ornamental 

 plants producing seed and coming to maturity the year in which 

 the seeds are sown. They may not be strictly annual in duration, 

 in the sense of dying and completing their cycle within a twelve- 

 month. Some of the potential perennials bloom and fruit the first 

 year from seed, and yet may live to the second or even the third 

 year (as eschscholtzia or California poppies, the China pinks, pansy 

 if allowed to do so) ; these plants are usually classed as annuals by 

 gardeners. Other so-called annuals are woody or even tree-like 

 in warm or tropical countries, as the castor-bean. 



The annuals are of easy propagation, being grown from seeds 

 of the previous year. The common flower-garden kinds may be
