LIST OF COOL ORCHIDS. 101 



crimson maroon, and it appears very beautiful when held up to 

 the light ; grows best in sphagnum, on a block. 



Nasonia. 



N. punctata. We have here a little plant that would easily 

 go into a fusee-box ; still it is worth growing, and is 

 nearly always in flower. Stem erect, only an inch or two high ; 

 leaves thick and fleshy, half an inch long, somewhat trique- 

 trous. Flowers borne on slender pedicels in the axils of the 

 leaves ; sepals and petals of a bright orange -scarlet colour, only 

 about a quarter of an inch long ; lip bright golden yellow, with 

 a brown spot in the centre ; grows well in peat and sphagnum. 

 (Also known as N, cinnabarina,) 



Odontoglossum. 



Of this genus there is scarcely a single species that 'is 

 not worth growing. All are beautiful, and they are daily 

 gaining ground in the estimation of the Orchid growing 

 and plant-loving public. Although natives of the tropics or 

 equatorial regions, still," as observed by Mr. Bateman, one 

 of the first promulgators of cool Orchid growing, there is not 

 a single species found growing in the sultry tropical lowland 

 plains. All affect the cool, airy ranges of the Cordilleras of 

 Mexico, New Granada, and Peru, where they grow and flower 

 profusely. A cool and moderately airy atmosphere, with abun- 

 dance of atmospheric moisture, is essential to their welfare. We 

 are sometimes told that they will grow in the ordinary green- 

 house, but that is a mistake. It is true they will grow in such 

 a structure, but not long. They do not require more heat 

 than ordinary greenhouse plants, but they want a great deal 

 more atmospheric moisture, or the energy of the plants would 

 soon be lost by evaporation ; and to prevent this taking place 

 we must keep the house closer, and employ more shading
