Bristles, awns, etc. provided with terminal or lateral spine-like hooks that are bent sharply backward.
Bark
The rough outer part of the cortex; loosely used for the entire cortex.
Basal
Pertaining to the extremity of an organ by which it is attached to its support; said of leaves when located at the base of the plant only. See rosette.
Beaked
Ending in a point, especially on fruits.
Bearded
Having long hairs.
Berry
A fleshy, indehiscent, pulpy, multi-seeded fruit resulting from a single pistil.
Bi-
Twice or doubly.
Biennial
Ordinarily applied to plants that live only two seasons; during the first season only leaves and stems are produced above ground, while the flowers and seeds are borne the second summer. Here used in a special sense in separating the biennial canes of the raspberries and blackberries from the stems of other woody plants. In these species, the canes themselves are biennial from underground perennial stems.
Bifurcate
Forked, as some Y-shaped hairs.
Bipinnate
Twice compound with the leaflets along each side of a common axis. The leaflets are further divided into pinnules.
Biternate
Twice ternate; structure basically ternate, but whose primary divisions are again each ternate.
Blade
The expanded part of a leaf.
Bloom
A waxy coating found on stems, leaves, flowers and fruits, usually of a grayish cast and easily removed.
Bole
The stem of a tree.
Bract
A modified leaf of an inflorescence. Several bracts form an involucre.
Bracteate
With bracts. Bracted.
Branch
One of the coarser divisions of a trunk or main stem; loosely, any division of the stem.
Branchlet
A smaller division of a branch.
Bristly
With stiff hairs.
Broad-elliptic
Wider than elliptic.
Broad-ovate
Wider than ovate.
Broken
Not continuous, as applied to bundle-traces.
Bronzing
A metallic bronze or coppery color, especially of foliage after a winter.
Bud
The rudimentary or resting end or branch of a stem; usually referring to the stage in which the growing tips pass the winter or dry season; also applied to undeveloped flowers or flower clusters. Scaly buds are protected by modified leaves or stipules. Naked buds lack such special protection. Usually one bud occurs in each axil or angle above a leaf, but these often branch and collateral buds, standing side by side, are thus produced; in some plants (walnuts, honeysuckle) several buds occur one above the other (superposed) in an axil.
Bud scale
A modified leaf or stipule (there may be one, a few, or many) protective of the embryonic tissue of the bud.
Bulb
A modified underground stem comprised of shortened central axis surrounded by fleshy scale-like leaves.
Bulbil
Small bulbs arising around the parent bulb.
Bulblet
Small bulbs arising in the leaf axils.
Bundle scar
Small dots or lines on the surface of the leaf scar marking the point of original departure of the vascular conducting strands into the leaf. Also called bundle trace.
