rrent trunk and horizontal branches. Wood firm,
close-grained and hard to split. Rich soil, latitude of Albany and
southward. Difficult to transplant, so it is rarely cultivated.

2. =Nyssa biflora=, Walt. (SOUR GUM.) Leaves 1 to 3 in. long, smaller
than in N. sylvatica; fertile flowers and fruit 1 to 3, in the axils;
stone decidedly flattened and more strongly furrowed. New Jersey to
Tennessee and southward. Too nearly like the last to need a drawing. All
the species of Nyssa may have the margin of the leaves somewhat
angulated, as shown in the next.

3. =Nyssa uniflora=, Wang. (LARGE TUPELO.) Leaves much larger, 4 to 12
in. long, sometimes slightly cordate at base, entire or angularly
toothed, downy beneath. Fruit solitary, oblong, blue, 1 in. or more in
length. Wood soft, that of the roots light and spongy and used for
corks. In water or wet swamps; Virginia, Kentucky, and southward.

ORDER =XXIII. CAPRIFOLIACEAE.=

(HONEYSUCKLE FAMILY.)

Shrubs (rarely herb or tree-like plants) of temperate regions.

GENUS =47. VIBURNUM.=

Shrubs or small trees with opposite, simple, petioled leaves. Flowers
light-colored, small but in large, conspicuous, flat-topped clusters at
the ends of the branches; blooming in early summer. Fruit small,
1-seeded drupes with flattened stones; ripe in autumn.

* Leaves distinctly palmately lobed 1.

* Leaves pinnately veined and not lobed. (=A.=)

=A.= Coarsely dentated 2.

=A.= Finely serrated. (=B.=)

=B.= Leaves long-acuminated 3.

=B.= Obtuse or slightly pointed 4.

[Illustration: V. Opulus.]

1. =Viburnum Opulus=, L. (CRANBERRY-TREE.) Leaves palmately veined and
strongly 3-lobed, broadly wedge-shaped or truncate at base, the
spreading lobes mostly toothed on the sides and entire in the notches;
petiole with 2 glands at the apex. Fruit in peduncled clusters, light
red and quite sour (whence the name "Cranberry-tree"). A nearly smooth,
small tree or shrub, 4 to 12 ft. high; wild along streams, and
cultivated under the name of Snowball-tree or Guelder Rose. In this
variety the flowers have all become sterile and enlarged. =Viburnum
acerifolium= (ARROW-WOOD) has also lobed leaves, and is much more
common. This species never forms a tree, and has dark-colored berries.
