produce roots freely, but the buds on them push very slowly and often 

 fail, although the young plants may have an abundance of roots. 



Adenocalymna. — Evergreen climbing shrubs, belonging to the same 

 order as the common Blgnonia (Trumpet-creeper), but being native of a 

 tropical climate, they require great heat to insure vigorous growth and 

 perfect flowers. Increased by cuttings placed where they will receive 

 plenty oi moisture and bottom heat. 



Adenocar-pus. — A genus containing both evergreen and deciduous 

 shrubs, beai'ing long racemes of yellow pea-shaped flowers. Propagated 

 by seeds, layers and cuttings of the uni-ipe wood under glass. 



Adenostoma (Chamiso). — A genus of only two species of small 

 evergreen trees or shrubs indigenous to California. Propagated by cut- 

 tings of the immatme shoots in sand under a bell glass or in frames 



Adhatoda. — Greenhouse o r 

 Btove evergreen shrubs fi-om Brazil 

 and India. Propagated by cuttings 

 of the young shoots placed in a posi- 

 tion where they will receive bottom 

 heat. 



Mgiceras (Goat Plant). — One 

 species from New Holland, some- 

 times cultivated for its white, fra- 

 gi-ant flowers. A rather stocky 

 shrub. Propagated by cuttings of 

 the haU-ripened shoots. 



JEsciilus (Horsechestnut). — De- 

 ciduous trees or shrubs. Numerous 

 species and varieties in cultivation. 

 The species are usually propagated 



from seed. The lai-ge, fleshy nuts Eig. 94.— hoksechest-

outside husk removed — then either sown and merely covered 

 with leaves or very light vegetable mold, or the nuts may 

 be preserved in pure sand or sphagnum untU the following 

 spring. They should be stored in a cool place to prevent 

 premature sp-routing and decay. If the boxes containing 

 the nuts are buried in the ground under an evergreen tree, 

 or in the shade of some building, they wiU usually 

 pass through the winter in good order. In the gennination of the 

 Horsechestnut, the nut does not bm-st open as in the Acoi-n, Butternut 

 and Hazelnut, but both plumule and radicle press through the envelope 

 on one side, as shown in figure 94. Varieties of the different species are 

 propagated by budding and grafting. The most certain mode is by 

 veneer grafting under gJass, and in this climate dming the month ot 

 August. Seedling stocks, placed in pots in eai-ly spring, may be grafted
