has a narrow strongly recurved frontal lobe, and in the 
shorter column which is constricted below the apex and 
much swollen above the base. The locality of the 
original plant has not been stated, but the species 
is known to occur in the district of Antioquia in Colombia. 
The material for our figure has been obtained from a 
plant imported by Messrs. Sander. Like other members 
of the genus, A. Cliftoni thrives in the intermediate house. 
It is most suitably grown in a compost of turfy loam 
and peat, with a small proportion of chopped sphagnum 
added to the mixture. During the growing season the 
plant requires a liberal supply of moisture at the roots 
and should be kept shaded from bright sunshine. When 
at rest only sufficient water should be given to keep the 
pseudobulbs plump; the plant may then be given a 
brighter and more airy situation, thus ensuring the 
ripening required to induce satisfactory flowering.
