conspicuous on the under surface with minute, reddish
tufts of down at the angles; stems smooth, 1-1-1/2 inches long; stipules
soon falling.

=Inflorescence.=--Late June or early July. In loose, slightly fragrant,
drooping cymes, the peduncle attached about half its length to a
narrowly oblong, yellowish bract, obtuse at both ends, free at the top,
and tapering slightly at the base, pedicels slender; calyx of 5 colored
sepals united toward the base; corolla of 5 petals alternate with the
sepals, often obscurely toothed at the apex; 5 petal-like scales in
front of the petals and nearly as long; calyx, petals, and scales
yellowish-white; stamens indefinite, mostly in clusters inserted with
the scales; anthers 2-celled, ovary 5-celled; style 1; stigma 5-toothed.

=Fruit.=--About the size of a pea, woody, globose, pale green, 1-celled
by abortion: 1-2 seeds.

=Horticultural Value.=--Useful as an ornamental or street tree; hardy
throughout New England, easily transplanted, and grows rapidly in almost
any well-drained soil; comes into leaf late and drops its foliage in
early fall. The European species are more common in nurseries. They are,
however, seriously affected by wood borers, while the native tree has
few disfiguring insect enemies. Usually propagated from the seed. A
horticultural form with weeping branches is sometimes cultivated.

=Note.=--There is so close a resemblance between the lindens that it is
difficult to distinguish the American species from each other, or from
their European relatives.

American species sometimes found in cultivation:

_Tilia pubescens, Ait._, is distinguished from _Americana_ by its
smaller, thinner leaves and densely pubescent shoots.

_Tilia heterophylla, Vent._, is easily recognized by the pale or silver
white under-surface of the leaves.

There are several European species more or less common in cultivation,
indiscriminately known in nurseries as _Tilia Europaea_. They are all
easily distinguished from the American species by the absence of
petal-like scales.
