There are no plants more remarkable among Orchids for the 
shape and colouring of the flowers than the species of the genus 
Catasetum ; and although they are sure to attract the attention of 
the observer, they are not favourites with Orchid-growers, and 
their cultivation has been greatly neglected. They are not diffi- 
cult to flower, and will grow freely when properly treated. 
C. longifoum is rare in collections: I obtained it from the 
Salween River, British Guiana. It thrives when grown in a 
basket of rough peat and sphagnum, and the pseudobulbs placed 
well above the rim, so that they may stand exposed to the air. 
The temperature of the East India house suits it well, where it 
should be supplied with plenty of water when growing, and as 
soon as the growth is completed it should have a good season of 
warm dry rest before it is set growing again.— W. W. S.
