Varieties. Under Aquatic Plants (which see) were 
described a number of very distinct hardy kinds, in- 
eluding the best of the hybrids associated with the name 
of M. Marliac. There is, however, another section of the 
genus equally beautiful and desirable for those having 
houses for the culture of Aquatic Plants. A selection of 
these tropical and tender kinds will be found below. 
D. and N. indieate respectively Day- and Night-flowering.

NYMPH2XA DEVONIENSIS. 
NYSSA. To the species described on p. 460, Vol. I., 
the following should be added : 
N. aquatica (aquatic). A syncnym of N. caroliniana. 
N. biflora (two-flowered). A synonym of N. caroliniana. 
N. candicans (whitish). A synonym of M. capitata. 
N. caroliniana (Carolina). j., fertile ones twin, on if eheiea ks 
Ijin. to 24in. long. April and May. jr. dark blue, the 
size of Peas. J. ovate-oblong, attenuated at base, entire, 3in. 
to 4in. long, glaucescent beneath. kh. 30ft. to 45ft. North 
America, 1759. Syns. NV. aquatica, N. bijlora. 
N. grandidentata ( e-toothed), A synonym of NV. uniflora.

petiolate, ovate, acuminate, with two or three large teeth on 
one side only, woolly beneath, 5in. to 6in. long. kh. 75ft. to SOft. 
Florida, 1812. Probably the finest species of the genus. SYN. 
N. grandidentata. 
OAK. In addition to the insect pests mentioned in 
Vol. Il. as being injurious to Oak-trees, must be named 
several others which in certain seasons constitute 
themselves pests. These, too, are mostly enemies to the 
foliage, and pests which are, moreover, found npon many 
other trees, including those of the orchard, as well. Two 
of the most destructive are the Mottled Umber Moth 
and the Winter Moth. Their attacks may be modified 
by timely grease-banding. Several species of Sawflies, 
however, feed upon the foliage of the Oak, and these 
are more difficult to reach. Hmphytus serotinus is a 
very common pest, and the larve may be found in late 
spring and early summer. They are about din. long, 
cylindrical, and of a lively green, with a powdering 
of a slightly lighter colour than that of the ground. If 
the parts of the trees infested could be reached with 
a powerful hose, the pests might be washed from the 
leaves and afterwards destroyed, as when alarmed they 
drop to the ground. 
OAK FUNGI. The chief fungi infesting Oaks were 
dealt with in Vol. II. There are, however, a few others 
which are found upon Oaks as well as upon other trees. 
One of the most destructive is Nectria ditissima, already 
dealt with in connection with Apple Canker. In 
Germany especially, Oax-trees are attacked by Sterewm 
frustulosum, which gives rise to the condition known 
as Partridge Wood, the discoloration haying a fanciful 
resemblance to speckled white breast-feathers found upon 
that bird. Hartig says that at first the ‘‘ wood assumes 
a deep red-brown colour, and then white blotches on a 
dark ground make their appearance, which stand in a 
certain relationship to the large medullary rays.” 
Eventually the characteristic white blotches decompose, 
forming perforations, and the mycelium may be noticed.
