information are invaluable to the cultivator, who rarely has 

 any idea of the precise circumstances under which his plants 

 grow naturally, and who, consequently, can only learn after 

 long and dear experience how to treat them. For this reason 

 I hope the following additional particulars concerning the 

 habits of other species of Oncidium, extracted from M. Des- 

 courtilz' MSS. will prove acceptable. 



O. divaricatum. Trunks of the most lofty trees, on the high mountains of the 

 Serra das Agoas, in the district of Ilha Grande. 



O. ciliatum. Common in the woods which cover the low plains among the hills 

 near Bananal. 



O. iridifolium. Branches of Orange and Lemon trees only. Very common in 

 the neighbourhood of the town of Bom Jesus de Bananal. It prefers dry 

 places, exposed to the sun. 



O. pubes. Thin forests clothing the table-land near Bom Jesus de Bananal. 



This species must be cultivated in a very damp stove, 

 where it may either be tied to a piece of wood and suspended 

 from the roof, or grown in a pot. In the latter case the soil 

 should consist of rough pieces of peat mixed with broken 

 bricks, or something which will form a communication with 

 the drainage below, and carry off superfluous water. The 

 only other thing to be attended to in its cultivation, is the 

 giving of water. This must be done cautiously, especially 

 when the young shoots begin to grow, for they are very apt 

 to suffer at that period. Afterwards it may be given more 

 freely, until the end of the growing season, when the plant 

 must be allowed a period of rest. 



It is propagated in the usual manner, namely by division.
