the surface of the pot. It should be placed in the warmest 
part of the stove, and its roots in particular freely syringed. 
The soil should be turfy peat, kept open with broken bricks 
or pots, to allow a free passage for the water. Water must 
be given more freely at certain seasons than at others ; but it 
does not require such a long period of rest as Catasetums 
and plants of that kind, and therefore may be kept almost 
continually growing. 
It is multiplied by division, the front shoots making the 
best plants. 
So little is correctly known concerning the native habits 
of the great order of Orchidaceous epiphytes, that 1 gladly 
avail myself of a vacant space to give the following localities 
of some other Oncidiums, as stated by M. Descourtilz in 
his MSS. 
Oncidium ciliatum. Flowers in September, in low woods, sur- 
rounding the table-land (plateaux) of the neighbourhood 
of Bananal. 
Oncidium iridifolium. Found in Brazil, exclusively on 
branches of the Orange and Lemon, flowering in April. 
The fruit is large, and has six large transparent wings. 
Very common in the province of St. Paul's, about the 
town of Bom Jesus de Bananal, choosing in preference dry 
places exposed to the sun. 
Oncidium pubes. Thin forests, surrounding the table-land 
near Bom Jesus de Bananal, flowering in the month of 
May. 
Oncidium | divaricatum. Trunks of the highest trees, in 
elevated mountains of the Serra das Argoas in the district 
of Ilha Grande, flowering in February.
