dehiscence |
|
More or less perpendicular to the central axis. |
fixed |

fixation |
|
Attached to the bearing structure in a manner allowing no significant rotation or declination in relation to it. |
scutate |
= buckler-shaped, scutiform |
solid shape |
|
Relatively thin with opposite broad oblong faces, planate to shallowly concave-convex, sometimes thickened about the periphery such that each face has a marginal rim; like an oblong shield. See also scutellate (platter-shaped, scutelliform), which is not clearly distinct in its application. |
infrafoliar |
|
position |
|
Upon the stem directly below a leaf insertion. |
superaxillary |
|
insertion |
|
Internodal but close to and directly above the axil(s). |
diffuse root |
> fibrous root |
STRUCTURE |
|
Any member of a dense system of adventitious, slender roots that arise from the base of a main stem and functionally replace an evanescent primary root. |
reproduction |
|
CHARACTER |
|
Type, morphology, disposition, function and/or dissemination of reproductive structures. |
attenuate 2 |
= tapered |
solid shape |
|
Gradually diminishing in breadth or diameter from one end to the other. |
nerve |
= vein; > costa, midnerve , midrib, midvein, rib |
STRUCTURE |
|
A strand belonging to any except the ultimate (least in diameter) order of vasculature in a leaf or other foliaceous structure. See also lateral vein, primary vein, secondary vein, tertiary vein, veinlet. |
sinus pl. sinus, sinuses |
|
FEATURE |
|
The space, indentation, or invagination (or, for some descriptive purposes, the outline thereof) between and delimiting any two consecutive or adjacent lobes or teeth of a structure. |
ceraceous 1 |
= cereous, waxen, waxy; > caesious, glaucescent, glaucous, pruinose |
coating |
|
Covered with wax or a wax-like substance. |
hastate 2 |
= halberd-head-shaped |
plane shape |
|
Basically triangular with an acute apex and two large, widely divergent basal lobes, each generally triangular and distally acute; like the stylized outline of the broad lateral face of a halberd head. |
phyllodium pl. phyllodia |
= phyllode |
STRUCTURE |
|
A leaf deemed to consist entirely or almost entirely of tissues evolutionarily derived from the petiole, all or a distal portion of which has become laminar, the original blade reduced to the point of absence or vestigiality. |
archegonium pl. archegonia |
|
STRUCTURE |
|
A female gametangium; a multicellular fertile organ of a mature gametophyte within which female gametes (eggs, ova) are produced and fertilized; having a broad, bulbous base and a narrower distal neck. Technically present but highly reduced and of no descriptive significance in Magnoliophyta. |
lanceoloid |
= lancehead-shaped, 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). |
three-… |
= tri… |
prefix |
|
Indicating presence of or constitution by three entities of the type denoted by the term's stem; as in three-cleft, three-flowered, three-ranked. See also thrice… (tri…, triple…). |
lanciform |
= lancehead-shaped, lanceoloid |
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 oblanciform (oblanceoloid). |
thrice-… |
= tri…, triple-… |
prefix |
|
Indicating presence of three hierarchical orders of the type of entity or pattern denoted by the term's stem; as in thrice-pinnate. See also three-… (tri…). |
emargination |
= notch |
FEATURE |
|
A relatively small, acute sinus at the distal end of a laminar structure. |
female |
= feminine |
reproduction |
|
Of the sex that produces megaspores and ova. |
scabrid |
= rough, scabrate, scabridous, scabrous |
relief |
|
Having small, stout, stiff, more or less acute protrusions. |
bracteate |
= bracted |
architecture |
|
Bearing or subtended by one or more bracts. |
ostiole |
|
STRUCTURE |
|
The distal aperture of a syconium (fig); in Ficus (Moraceae). |
costule |
|
STRUCTURE |
|
A longitudinal primary vein in a diminutive laminar structure, such as the blade of a leaflet, pinna or pinnule; a diminutive costa (rib). |
prolate |
|
plane shape |
|
Symmetrically elongate parallel to the developmental or polar axis. |
