Orchid Order {Orchidea). A Mrge and very remark- CASE 

 able group, marked by the varied shapes and colours of their |^ 

 flowers, which are often of great beauty. The genera Catase- 

 tum, Myanthus and Monachanthus are interesting, in conse- 

 quence of their trimorphic inflorescence illustrated in the 

 coloured plates of Catasetum macrocarpum^ Rich., and C. cris- 

 tatuiriy Lindl. The species of Orchidese are found aill over the 

 world, excepting in very cold and dry regions. ■;• '^- -'-^ '■

 tropics they are generally found growing upon the trunks of 

 the trees, &c. (epiphytes). From the beauty and singularity 

 of their flowers, they are favourite hot-house plants. Few
