[ December, 
vigorously. The N. advena , however, does not appear to relish being planted in 
cold spring-water, that is to say, if planted near to the spot where the spring is 
continually running into the pond. It is most suitable for ponds or lakes of 
large dimensions, and may be planted in the way reccommended for Nymphcea 
alba , in the Florist for 1871, p. 205. It begins to flower about midsummer. 
Nuphar Kalmiana was introduced from Canada in 1807, and is figured in 
the Botanical Magazine , t. 1243. It is a nice little plant, and bears the same 
relation to the Nuphar advena as the Nymphcea odorata does to N. alba (see 
Florist, December, 1871, p. 274). The flowers are yellow, about the size of a 
shilling, and are usually produced in July and August; the leaves are from 2 in. 
to 2| in. across, and lay flat upon the surface of the water. It is very suitable 
for tanks or basins of small size. If planted in ponds or lakes, let it be 
done as recommended for Nymphcea odorata , or you may just peer over the 
margin of your lake some unlucky morning and find your plant missing. It is 
not very commonly met with. 
Nuphar sagittcefolia is the N. longifolia of Michaux. It was sent from 
Georgia in the year 1824, and is figured in the Flora Americana of that author 
(v. 1, p. 312). The small yellow flowers are produced in July and August, and 
the leaves are arrow-headed in shape. Unfortunately the plant is now lost to 
our gardens, but from the foliage being so dissimilar to that of any other member of 
the family, it would be a very desirable to get it reintroduced, and to this end it is 
here placed on record.—W. Buckley, Tooting. 
FRUIT-CULTURE.—DECEMBER. 
@ HE instructions for November will serve for this month. Fruit-trees of all 
kinds may be planted in mild weather, if anything has prevented it being 
f done before; it is better done now than put off till spring. Give all 
newly planted trees a good dressing of half-rotten dung around the roots* 
and see that Standards and others liable to be blown about by the wind are 
properly secured to stakes. Proceed with the pruning and nailing of Wall-trees 
in mild weather; also the pruning and thinning out of Standard and Dwarf 
trees. Endeavour to get through as much of this work as possible before spring, 
when so many other operations, which admit of no delay, demand attention. 
Give British Queen and other tender sorts of Strawberries a dressing of half- 
rotten dung, to protect the crowns from injury during frosty weather. 
In-Doors. —The directions given last month for Pines are applicable this, 
and should be steadily adhered to. The fruiting house will require careful 
attention at this season ; give a little air at every favourable opportunity, and 
water with tepid water, when they require it; keep the atmosphere moderately 
dry, and maintain a temperature of from 60° to 65° at night, and 80° to 85° 
during the day. Attend to succession plants in all stages, and see that they have 
a nice steady bottom-heat; keep them steadily moving, but not excited, and in 
frosty weather use coverings as much as possible, in order to obviate the
