phylloclade |
= cladode, cladophyll |
STRUCTURE |
|
A stem segment that functions as a leaf; often more or less compressed. |
|
lancehead-shaped 2 |
= lanceoloid, lanciform |
solid shape |
|
Considerably longer than broad, compressed or not, broadest near the base and somewhat concavely attenuate to the apex, the attenuation in all median longitudinal planes or else largely confined to one, depending upon the extent of compression, if any. See also oblanceoloid (oblanciform). |
|
thorn |
= spine |
STRUCTURE |
|
Any sharp, stiff, simple or branched, woody appendage having vascular tissues confluent with those of the bearing structure. "Spine" is often preferred when the appendage is homologous with a leaf or stipule, and "thorn" when it is homologous with a branch. See also prickle. |
|
fatiscent |
= crumbling; > farinaceous, mealy |
texture |
|
Easily disintegrating in relatively small pieces, either spontaneously or under pressure. |
|
…-sawtoothed |
= …serrate |
margin |
|
Having the number of orders of sawteeth indicated by the prefix, one upon another; as in twice-sawtoothed. See also …-scalloped (…crenate), …-toothed (…dentate). |
|
barb 1 |
|
STRUCTURE |
|
Any relatively short, stiff, sharp, acutely inserted or bent, antrorse or retrorse, terminal or lateral appendage. |
|
wood |
= xylem |
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. As commonly used, the term wood generally refers only to secondary xylem, which constitutes the bulk of a mature woody stem, but it properly refers also to primary xylem, wherever found. See also sapwood, heartwood. |
|
orientation |
|
CHARACTER |
|
Attitude or direction with respect to some explicit or implicit structure(s) or context. The lexicon relating to orientation includes some conceptually complex terms whose meanings also embrace aspects of structural composition or shape. Overlaps conceptually with arrangement, habit, insertion, position, and shape. |
|
development |
= ontogeny |
CHARACTER |
|
Mode or pattern of growth and differentiation. |
|
primocane |
|
STRUCTURE |
|
A biennial or perennial stem before it has begun flowering, when the latter does not occur until at least its second season of growth; esp. in Rubus (Rosaceae). |
|
lustrous |
= glossy, laevigate, polished, shining, shiny |
reflectance |
|
Uniformly reflecting a high proportion of incident light at all angles. |
|
fragrant |
|
odor |
|
Sweet or otherwise pleasant. |
|
setulose |
= hispidulous, small-bristly |
pubescence |
|
Finely setose (hispid). |
|
bud |
|
STRUCTURE |
|
A rudimentary, unexpanded stem, stem branch, inflorescence, inflorescence branch, or flower, or a combination thereof, in a resting state; enveloped or not by subtending protective scales. |
|
corky |
= suberous |
texture |
|
Firm, relatively light, discontinuous but strongly cohesive, and resilient. |
|
subpetiolar |
|
insertion |
|
Just below the point of petiole insertion. |
|
acuminate |
= concave-tapered |
apex |
|
Gradually diminishing in width or diameter to a slender tip, the sides longitudinally concave. Corresponds with attenuate for base shape. |
|
…ranked |
= …stichous |
arrangement |
|
Disposed along the axis in the number of distinct ranks indicated by the prefix; as in two-ranked. |
|
exocarp |
= epicarp |
STRUCTURE |
|
The outermost tissue layer of a pericarp. |
|
astomatiferous |
= non-stomate-bearing |
architecture |
|
Lacking stomates in the epidermis. |
|
mucous 2 |
= mucilaginous; < glutinous |
texture |
|
Slimy. |
|
viscin |
= elastoviscin |
SUBSTANCE |
|
A sticky, elastic material, especially that forming the threads that sometimes connect pollen grains. |
|
viviparous |
|
reproduction |
|
Producing sexually or asexually generated offspring that begin growth and development while borne upon the parent plant. |
|
spire-shaped |
= strombuliform |
solid shape |
|
Attenuate-spiral in three dimensions, the coils contiguous or not. |
|
…cellular |
= …celled |
architecture |
|
Having the number of cells indicated by the prefix; as in bicellular, multicellular, oligocellular. |
