catadromous |
|
venation |
|
Having the first lateral vein in each pinna or primary segment of the frond arise from its midvein on the side toward the base of the frond, the pinnule or secondary segment that it leads to often disproportionately larger than the next distal ones. |
crateriform |

|
Having a distal, concave, relatively thin-walled, basically hemispherical portion surmounting a much narrower, transversely round, pedestal-like base. |
epidermis pl. epidermides, epidermises |
|
STRUCTURE |
|
The anatomically distinct, outermost, living tissue that encloses and protects the other tissues of a plant organ or part, usually overlaid by an exuded waxy cuticle; resulting from primary growth, disrupted and shed as a consequence of secondary growth if that occurs; consisting mainly of cells not further specialized, otherwise including various types of more specialized cells associated with trichomes and stomates. |
bifurcate |
< forked, furcate |
solid shape |
|
Having two terminal, antrorse branches or divisions arising from a common point or level, like the prongs of a fork. |
circumscissile |
|
dehiscence |
|
Splitting transversely through the exterior wall about its entire circumference, the resulting upper cap-like portion falling away. |
pouch-shaped |
= bag-shaped, saccate, sack-shaped |
solid shape |
|
Irregularly obovoid with an exterior aspect intermediate between inflated and flaccid; like a closed pouch or bag. |
valvate 1 |
|
aestivation |
|
Whorled and with members not overlapping, adjacent members laterally contiguous at their margins. |
orbicular |
= globose, globular, rotund, spheric(al), spheroid(al) |
solid shape |
|
Uniformly convex, circular in any median section and in outline when viewed from any angle; like a sphere or globe. |
crusty |
= crustaceous |
texture |
|
Thin, dry, hard, and brittle. |
oligo… |
= few-… |
prefix |
|
Indicating presence of or constitution by a relatively small number of entities of the type denoted by the term's stem; as in oligandrous, oligocellular, oligofloral, oligospermous. See also multi… (many-…, pluri…, poly…). |
septal |
|
insertion |
|
Upon or otherwise directly associated with the septum or septa. |
jointed |
= articulate(d) |
architecture |
|
Elongate with one or more distinct, relatively narrow zones of demarcation between adjacent main portions of the whole, these joints (articulations) often thicker and sometimes sites of eventual abscission. |
fine-pitted |
= foveolate, scrobiculate |
relief |
|
Finely pitted (foveate). |
trapeziform |
|
plane shape |
|
Four-sided and either asymmetrical or bilaterally symmetrical like a triangle truncated distally perpendicular to its central axis. |
tuberculose 1 |
= tuberculate, verrucose, warty |
relief |
|
Covered with small, relatively broad, irregularly shaped, obtuse protrusions. |
moniliform |
= beaded |
solid shape |
|
Elongate, relatively slender, transversely round, and more or less regularly constricted over its length, the whole straight or variously curved; like a necklace of beads. |
cap cell |
|
STRUCTURE |
|
The single cell, or one of the several cells, forming the uppermost (distal) portion of an antheridial wall. |
squamella 3 pl. squamellae |
= lodicule, squamule |
STRUCTURE |
|
One of two or three small, scale-like structures inserted at the base of the androecium, distal to the palea, in most grass (Poaceae) flowers; often regarded as a vestigial branch or perianth member. |
dodeca… |
= twelve-… |
prefix |
|
Indicating presence of or constitution by twelve entities of the type denoted by the term's stem; as in dodecandrous, dodecalocular, dodecastylous. |
funiculus pl. funiculi |
= funicle; < stalk |
STRUCTURE |
|
A stalk that attaches an ovule to a placenta of the ovary wall. |
plicate 1 |
|
aestivation |
|
Valvate with each member strongly infolded longitudinally. |
barbella pl. barbellae |
= barbel |
STRUCTURE |
|
A small barb. |
oblique 1 |
|
apex |
|
Asymmetric about its longitudinal axis. |
throat 1 |
|
STRUCTURE |
|
The far distal portion of a perianth, calyx, or corolla tube, or of a leaf sheath, surrounding the orifice of the tube or sheath, sometimes constricted relative to the diameter of the main body of the tube or sheath; except in disc florets of Asteraceae (Compositae). |
megaphyll |
= leaf, macrophyll (not recommended); > 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. |
