112 FLOWER-GARDENIXG. 



Polygata cordata, Heart-sliaped Polygata, A beautiful little 

 plant, producing abundance of rich purple flowers nearly all 

 the winter. 



Protea. A beautiful race of plants, the foliage of which is 

 very diversified, and the flowers also ; being red, white, straw, 

 brown, green, and purple, and most of these colors are fre

 to June. 



Primula. In this genus are embraced all the varieties of 

 the Primrose, Polyanthus, Auricula, Cowslip, Oxlip, etc.,

 The flowers, which appear early in spring, are mostly sweet-

 crimson, etc., which in some are beautifully variegated. The

 white and pink, natives of China, producing umbels of flowers 

 from January to May. 



Pyrus Japonica alba, or Cydonia Japonica. One of the

 at different seasons in a green-house or warm room. 



Rhododendron, Rose Bay. A beautiful genus of plants, 

 chiefly natives of India, furnishing clusters of flowers of various 

 shades, as purple, scarlet, or crimson, and these variegated in 

 spots and flakes ; in flower from March to May. 



Rosca, Rose. This Queen of Flowers, so universally ad

 ized world ; and varieties have been so multiplied of late 

 years, as to render it difficult to make a judicious choice ; many 

 of the new varieties, however, being shy bloomers, are not so 

 desirable for green-house culture as the common China Rose,
