may be employed ; and its leaves being small, and not very numerous, do not much 
contribute towards doing so. It should be grown in two-thirds sandy peat, and one- 
third turfy loam, and kept in a dry, airy situation through the winter ; in summer 
no particular situation or treatment not applicable to greenhouse plants in general, 
is required for it. 
Propagation by cuttings is easily effected, if suitable are chosen, and placed in a 
proper preparation of silver sand, fine peat, &c, in heat, and covered with a bell-glass. 
To Mr. Jackson, of the Kingston Nursery, who received his plants late in 1843, 
from the nobleman already mentioned, we are indebted for the subject of our drawing. 
Tetratheca is from the Greek word tetra, four, and theke, a cell ; in allusion to 
the four cells of the anthers.
