Bristles, awns, etc. provided with terminal or lateral spine-like hooks that are bent sharply backward.
The rough outer part of the cortex; loosely used for the entire cortex.
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.
Ending in a point, especially on fruits.
Having long hairs.
A fleshy, indehiscent, pulpy, multi-seeded fruit resulting from a single pistil.
Twice or doubly.
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.
Forked, as some Y-shaped hairs.
Twice compound with the leaflets along each side of a common axis. The leaflets are further divided into pinnules.
Twice ternate; structure basically ternate, but whose primary divisions are again each ternate.
The expanded part of a leaf.
A waxy coating found on stems, leaves, flowers and fruits, usually of a grayish cast and easily removed.
The stem of a tree.
A modified leaf of an inflorescence. Several bracts form an involucre.
With bracts. Bracted.
One of the coarser divisions of a trunk or main stem; loosely, any division of the stem.
A smaller division of a branch.
With stiff hairs.
Wider than elliptic.
Wider than ovate.
Not continuous, as applied to bundle-traces.
A metallic bronze or coppery color, especially of foliage after a winter.
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.
A modified leaf or stipule (there may be one, a few, or many) protective of the embryonic tissue of the bud.
A modified underground stem comprised of shortened central axis surrounded by fleshy scale-like leaves.
Small bulbs arising around the parent bulb.
Small bulbs arising in the leaf axils.
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.
