|
STRUCTURE |
|
A vegetative propagule by which a gametophyte reproduces asexually; produced by a process analogous to budding, from a more or less cupulate specialized area (gemmae cup) on the surface of the plant body (thallus); in Psilotophyta, Lycopodiophyta, Equisetophyta, Polypodiophyta. |

nodiform |
= gongylodate, gongyloid, knob-shaped, knot-shaped |
solid shape |
|
Approximately globose, the surface convoluted or not, like a knob or knot; usually applied only to structures or components that are relatively small. |
xylem |
= wood |
STRUCTURE |
|
The water-conducting and usually main supporting tissue of a plant or portion thereof, characterized by the presence of tracheary elements (tracheids and sometimes vessel elements); the lignified tissue of a plant or component structure, composed almost entirely of secondary tissue, i.e., that derived by secondary or lateral growth from a cambium in structures a season or more old. See also sapwood, heartwood. |
bud scale |
|
STRUCTURE |
|
A scale that, alone or aggregated with others, envelops and protects a bud. |
heartwood |
|
STRUCTURE |
|
The senescent inner or central portion of the wood (xylem) of an older stem or root, its cells no longer living, in which conduction has ceased and primary reserve materials are no longer stored; often containing terminal metabolic products; usually darker in color than the living, conducting sapwood that encircles it. |
alternate 1 |
|
arrangement |
|
Inserted singly along the axis, each at a different level and each diverging on a different radius than the ones next above and below. |
pistil |
> carpel |
STRUCTURE |
|
Any simple or compound, discrete or histologically distinct, female (ovule-producing) floral structure, or any putatively homologous sterile structure; comprising an ovary and one or more stigmas borne either directly upon the ovary or upon one or more intervening styles. See also gynoecium. |
leaf 1 pl. leaves |
= frond, macrophyll (not recommended), megaphyll; > frond, needle |
STRUCTURE |
|
A principal, vegetative shoot organ borne laterally from a stem node; its vascular tissues, if any, continuous with those of the stem; undergoing no significant secondary growth; usually more or less bilaterally symmetrical; comprising a distal, usually laminar blade and/or a proximal stalk (petiole) or sheath; usually a primary site of photosynthesis. |
tongue-shaped |
= lingulate |
solid shape |
|
Broadly elongate and compressed, one broad face more or less plane and the other convex, the edges rounded between them; like a tongue. |

= crenule |
FEATURE |
|
A diminutive scallop (crena). See also sawtooth, sawtoothlet, tooth (dens), toothlet. |
disk |
|
STRUCTURE |
|
See disc. |
paired |
= conjugate, geminate |
arrangement |
|

…cellular |
= …celled |
architecture |
|
Having the number of cells indicated by the prefix; as in bicellular, multicellular, oligocellular. |
