any other known species of the genus. 
Mr. S. Taylor. — Rendle’s tank system or adaptations of it 
are becoming almost universal for all sorts of erections. It 
may be suited to either bottom or surface heat, and be made to 
afford it either dry or moist; in short, there is no description of 
heating for horticultural purposes to which it is not most pre¬ 
ferable. For pits for early forcing it is entirely superseding 
the dirty, troublesome, and expensive mode of heating by dung 
linings; and the comparative cost is quite nominal. You will 
get the particulars for construction in his treatise. Mr. R. well 
deserves the gold medal he obtained for the invention. See also 
the article in present number. 
An Amateur had better preserve his seeds from China 
until the beginning of February. They should be sown in light 
rich soil, on a gentle bottom heat.

CALENDAR FOR DECEMBER. 
Stove. The month before us admits of but few observations 
in the calendar. The best that can be done is only keeping the 
plants as they are; and so that they do not assume a retrograde 
movement, it is all well, any beneficial advance being out of the 
question until the turn of the season. The temperature of this 
department for some time forward will be purely artificial; and 
as the cold increases, so must the fire; and this will render more 
water necessary, but it must still be used with caution. Y\ here 
the collection is of any considerable number, of whatever de¬ 
scription it may be, there will always be a quantity of the 
younger, and perhaps some of the mature plants, which will 
evince an inclination to grow. These attempts it is better to
