|
| Baccate |
Pulpy, fleshy. |
| Barbed |
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. |
| Bur |
Any rough or prickly seed envelope. |
| Burl |
A knot or woody growth of very irregular
grain. |
| Buttressed |
With supporting wings. |
