different in its buff-coloured lip, and its longer racemes, which appear later in 
the season. The flowers are deliciously fragrant. 
The variety Ballantineanum is the most distinct déviation from the type 
which has yet appeared, and is chiefly characterised by its shorter, fewer-flowered 
racemes, which appear earlier in the year. 
The cultivation of these plants is now pretty generally understood. They 
should be placed in the warm house, and during the growing season a copious 
supply of water must be given. When at rest the amount should be greatly 
reduced, but they may never be allowed to become dry. 
The geographical range of this species appears to be very imperfectly known. 
M r F. W. Burbidge saw it growing luxuriantly at Singapore, as recorded in his 
Gardens of the Sun , p. 18, where, however, it may hâve been an introduced plant.
