viding plenty of water is given to it during its growth, and a 
temperature of 60° to 65°. — Native of Guatemala. 
133. Epidendrum Schomburgkii. Plant with upright stems, 
from two to three feet long; leaves alternately up; their 
flower spike rising from the summit of the stem ; flowers of a 
bright red, produced in clusters. It requires pot cultivation in 
a mixture of turfy peat, rotten wood, and sphagnum. It does 
not require so much water as some other species; temperature 
from 65° to 70°. — Native of British Guiana. 
134. Epidendrum pallidiflorum. This species is not very 
beautiful, but still is worthy a place in every large collection : 
its flowers are a pale yellow colour, and produced in a bunch or 
corymb. The plant will succeed in a mixture of sphagnum, 
turfy peat, and rotten wood, with a temperature of 65° to 70°.— 
Native of Brazil.

THE TANK SYSTEM OF HEATING. 
We have on several occasions lately recommended the adoption 
of Rendle’s tanks for heating nearly every description of horti¬ 
cultural erections, from a conviction of their general utility, and 
comparatively trifling expense; and we feel gratified in being 
able to state that in every instance where properly adapted 
they have been found efficient. 
We have now an opportunity kindly afforded us of describing 
an important improvement in their construction. A method 
particularly suited to pits required for early forcing, and by 
which the heating surface of the tank is increased to fully 
double its previous extent, at the same time securing a fine 
circulating atmospheric or surface heat. It is well known to 
those who have adopted the tanks for the supply of bottom heat 
in pits, that for obtaining and maintaining any amount of heat 
they are fully sufficient; yet from the warmth hitherto having 
to ascend to the surface through the soil or tan of the beds, it 
has imbibed so much of the moisture contained in the bed as to 
render it necessary either to admit a large proportion of air at 
all times by the lights, or to have one or more close pipes as a
