A унаа stove deciduous species, requiring to be cultivated in a 
basket or upon а block of wood, as its stems are long and pendu- 
lous, the joints much swollen. Duringthe growing season, it enjoys 
ап abundant supply of water, with a good heat; but, when the 
growths are complete, the plant should be removed to a cooler 
кеме, and less water, as a matter of course, will suffice, The 
two following varieties are both rareand very desirable : candidum 
(album) and petals pure white; lip the same, but with 
ап orange-coloured base, (Е. M. n. s. 212.) Lowii, flowers white,

Овр. Composite. Handsome greenhouse trees, thriving

Juan Fernandez, but probably the only one hitherto intro- 
duced is that described below. Propagated by seeds. It 
is, however, usually cultivated from imported plants.
