' CATALOGUE OF GREEN-HOUSE PLANTS. 117 



the Primrose, Polyantlius, Auricula, Cowslip, Oxlip, &c., 

 already inserted in our Biennial and Perennial catalogues. 

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

 scented, and of various colours, red, white, yellow, lilac, 

 purple, crimson, &c., which in some are beautifully varie- 

 gated. Tlie above are natives of England ; besides which 

 are two varieties, white and pink, natives of China, produ 

 cing umbels of flowers from January to May. 



Pyvus Japonica alba, or Cydonia Japonica. One of the 

 earliest flowering dwarf shrubs of the garden, producing 

 beautiful blush flowers ; there is another variety, which pro- 

 duces scarlet blossoms, already described in our catalogue 

 of shrubs. 



Reseda, Mignonette. This fragrant little plant has been 

 already treated of as an annual ; it may, however, be kept 

 under cultivation from January to December, by sowing 

 seed 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 va- 

 riegated in spots and flakes ; in flower from March to May. 



Rosea, Rose. This Queen of Flowers, so universally ad- 

 mired, nature seems to have distiibuted over the whole 

 civilized world ; and varieties have been so multiplied of 

 late years, as to render it diflicult 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, a select assortment of which, carefully culti- 

 vated, will produce blossoms from January to December, 



Rosmai-i)ius, Rosemary. A fragrant, half-hardy, slender- 

 leaved plant, which has been held in great esteem for ages. 

 In some parts of Europe it is customary to distribute sprigs 

 amono^ the guests at weddings and funerals. 



Ruella. A desirable plant, of which there are several 

 species ; they produce purple or scarlet tunnel-shaped flow- 

 ers from December to March.
