Some of these constitutional characters are much modified by care and
environment, as all are more or less. Care and local environment often
make it possible to grow varieties in special localities, although some
varieties are inherently adapted to a greater number of diverse conditions
than others. Bartlett, Seckel, and Kieffer have in common as one of their
most valuable characters adaptability to a great diversity of soils and
climates.
Trunk and branch.— The trunk does not count for much in descriptions
of varieties. The height of the trunk usually depends on the whims of the
pruner. Whether stowt or slender is sometimes noteworthy. The bark
may be smooth or shaggy. Color of bark is often a valuable diagnostic
character, especially in young trees. Many if not most varieties of pears
can be identified in nursery rows by an expert nurseryman from the color
of the bark. Seckel, Sheldon, and Beurré d’Anjou have remarkably
distinctive color as young trees.
The branches of pear-trees are often reliable guides in identifying
varieties in orchard or nursery, especially when trees are leafless and fruitless.
The twisting, drooping branches of Winter Nelis serve to identify that
variety at any time. The zigzag branches of Beurré d’Anjou and Bloodgood

are typical. The branches of Beurré Superfin are rough and shaggy.
