CATALOGUE OF GREENHOUSE PLANTS. 3gl 



plants hereinafter described, and that the exceptions are 

 shown in the monthly calendar. 



That such Bulbous roots as are generally embraced in 

 Greenhouse Catalogues, from their being adapted to artifi- 

 cial culture, have been already treated of, under each head, 

 in numerous articles ; to which the reader is referred. 



That with the exception of Hot-house plants, which re- 

 quire a uniformly warm climate to perpetuate their exist- 

 ence, all such other tender and half hardy plants as need 

 protection in Winter, may come under the denomination of 

 Greenhouse Plants ; some species however, notwithstanding 

 this concession, may be preserved in frames, pits, cellars, or 

 warm rooms. 



That many of those species designated thus, and 

 thus j in our two first catalogues, are of such description ; 

 and as they have been treated of in the chapters thereto an- 

 nexed, the following catalogue and explication will be 

 necessarily brief, when compared with one general catalogue 

 of exotic plants. 



Acacia. Of this and the Mimosa, which are by some con- 

 sidered as one genus, there are upwards of a hundred spe- 

 cies and varieties, suited for artificial culture. The blossoms 

 which are generally straw colour and yellow, except the 

 most tender, some of which are crimson, succeed each 

 other from February to June. 



Agapanthus. A beautiful species of Lily, producing large 

 blue flowers from April to June ; some varieties have striped 

 leaves and delicate white blossoms. 



Aloe. Of this genus, there are numerous species and 

 varieties, some of which are very curious, being possessed of 

 all the varied forms and figures peculiar to succulent plants. 

 Some species flower annually from March to September, 

 and all, except the Century Aloe, blossom frequently; the 

 colours are generally yellow, pink, and red. The singular 

 figure and habit of these plants render them desirable for 

 greenhouse culture.
