ACANTHOPANAX ACHIMENES. 1 59 



Acanthopanax. Like Aralia. 

 Acanthophcenix. Palmacecs. 



Propagated by seeds, sown in a moist bottom heat, in 

 a well decomposed compost of one part loam, one of 

 peat, one of leaf mold, and one of sand. 

 Acanthus (Bear's Breech). AcanthacecB . 



Propagated by seeds sown in gentle heat, or by division 

 of the root in autumn or early spring. Also by root- 

 cuttings. Water carefully. 



Acer (Maple). Sapindacecs. 



Stocks are grown from stratified seeds, which should 

 be sown an inch or two deep. Some very early-ripening 

 species, as A. dasycarpum and A. rubrum (the silver or 

 soft maple and the red maple), come readily if seeds are 

 simply sown as soon as ripe. They will not keep well 

 until the next spring. Varieties are often layered, but 

 better plants are obtained by grafting. The Japanese 

 sorts are winter-worked on imported A. polymorphum 

 stocks, either by whip- or veneer-grafting. Varieties of 

 native species are worked upon common native stocks. 

 Maples can also be budded in summer, and they grow 

 (generally with some difficulty) from cuttings of soft and 

 ripe wood. 



Aceras. Orchidacea. 



Propagated by carefully made divisions of the tubers. 

 (See under Orchids. ) 



Achillea. Including Ptarmica (Yarrow, Milfoil). Com- 

 positiz. 

 Propagated by seeds, root divisions and cuttings, dur- 

 ing spring. 



Achimenes, including Scheeria. Gesneracece. 



Propagated by seeds, carefully sown in well-drained 

 pans, which are filled nearly to the rim, leveled, and well 

 watered vvith a fine rose. Sow seed and cover lightly 

 with sand, and place in a shady position. Keep moist, 

 and apply water very lightly. Place a sheet of glass over 

 the seed-pan. After large enough to be pricked off, treat 

 like rooted cuttings. By scales of the corms, rubbed off 

 and sown like seeds, barely covered with sand, and 

 placed in bottom heat. By leaves, set into pots of sim- 

 ilar soil as for cuttings, placing all the petiole below the 

 surface, and placed m bottom heat. _ (Fig. 8i.) By cut-
