particularly in the trunks of old willows, and which has been well 

 dried before using. Either of the above are good for the purpose, 

 but I prefer the former. With either of them, mix a tenth part of 

 sea sand for the humid situated garden or place, and the same pro- 

 portion of a good loamy soil for a dry garden, &c. In such a soil 

 the plants will nourish so as to bloom amazingly. 



Some taste as to arrangement of the kinds and colours is re- 

 quired, so as to produce the greatest effect ; this the cultivator will 

 doubtless attend to, so that a specifying of the kinds will be neces- 

 sary for me to add. I shall, therefore, shortly send a list, with 

 colours of flowers, height of growth, &c. of the most superior kinds 



which I cultivate in my nursery grounds.

 Oncidiums— The greater part of this genus are highly beautiful 

 flowering plants. The flowers are produced in branching panicles, 

 containing a considerable number of flowers upon each. The plants 

 are of easy culture, grow very freely, and bloom very profusely. 

 The whole species deserve a place in every collection. 



1. OncUium allissimum, The tallest growing. As the name 

 imports, the flower stem reaches to a great height ; with me it has 

 extended to twelve feet, and numerously branched. The flowers 

 are of a fine yellow, spotted with brown. It blooms in August and 



September. 



2. 0. ampliatum. This species is a most profuse bloomer, pro- 

 ducing its fine blossoms upon a branching raceme of considerable 

 size. The flowers are very showy, yellow, slightly spotted with 

 brown. Blooms in February and March. 



3. 0. barbalum, The bearded flowered. The flower stem rises 

 to near two feet high, bearing a panicle of yellow flowers, which 

 are singularly pretty. It blooms in April and May. 



4. 0. bicornutum, The two horned. This kind produces «
