scutelliform |
= platter-shaped, scutellate |
solid shape |
|
Relatively thin with opposite broad oval faces, shallowly concave-convex; like a serving platter. See also scutate (buckler-shaped, scutiform), which is not clearly distinct in its application. |
|
eroded |
= erose |
relief |
|
Having rough, very irregular depressions throughout. |
|
spicy |
|
odor |
|
Pleasantly pungent, reminiscent of spices. |
|
forked |
= furcate; > bifurcate |
apex |
|
Having two or more terminal, antrorse branches or divisions arising from a common point or level, like the prongs of a fork. |
|
sub-basifixed |
|
fixation |
|
Attached just above its base. |
|
theca pl. thecae |
= pollen sac |
STRUCTURE |
|
Any of the one, two or four ontogenetically distinct, pollen-producing sectors (microsporangia) of an anther. In some taxa the walls between pairs of adjacent thecae break down as an anther approaches maturity, the mature anther thus ultimately containing half as many locules as thecae. |
|
acrid 2 |
= pungent |
odor |
|
Sharp or astringent. |
|
loose 2 |
|
texture |
|
Soft overall, discontinuously and only weakly cohesive. |
|
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. |
|
netted 3 |
= reticulate |
relief |
|
Having prominulous, more or less regularly interconnected lines. |
|
papillar(y) |
= papilliform |
solid shape |
|
Small, conoidal, and protruding from a larger structure; resembling a pimple; esp. trichomes. |
|
ceraceous 2 |
cereous, waxen, waxy |
texture |
|
Having the consistency of wax. |
|
cordate 2 |
= heart-shaped |
plane shape |
|
Fairly regularly attenuate from a broad, bilobate base to a narrow apex, the lobes large, rounded, retrorse, and intersecting; like the stylized outline of the broad lateral face of a heart. See also obcordate. |
|
ramal |
|
position |
|
Upon or otherwise directly associated with the stem branches. |
|
di… |
= bi…, two-… |
prefix |
|
Indicating presence of or constitution by two entities of the type denoted by the term's stem; as in diadelphous, dicyclic, dimerous. See also individual entries for terms with this prefix whose meanings, at least in some applications, are more specific than usually indicated by such combination; and also double-… (bi…, twice-…). |
|
scabridous |
= rough, scabrate, scabrid, scabrous |
relief |
|
Having small, stout, stiff, more or less acute protrusions. |
|
small-dotted |
= puncticulate |
coloration |
|
Finely dotted (punctate). |
|
stolon |
= runner |
STRUCTURE |
|
A slender stem that grows horizontally upon or just beneath the ground surface, rooting at the nodes and giving rise to erect shoot segments at some nodes and/or at its apex. |
|
…grooved |
= …colpate, …fossulate, …furrowed, …sulcate, …valleculate |
architecture |
|
Having the number of grooves indicated by the prefix; as in three-grooved, 5-grooved. |
|
taproot |
< primary root |
STRUCTURE |
|
A primary root that remains dominant through the life of the plant as the main axis of a vertically oriented system that penetrates the substrate to a considerable depth. |
|
latex pl. latices, latexes |
|
SUBSTANCE |
|
A moderately viscous and sticky exudate, often milky, sometimes otherwise colored or clear. Overlaps conceptually with gum. |
|
antherozoid |
= spermatozoid; < sperm |
STRUCTURE |
|
A motile male gamete, produced within an antheridium. |
|
mucro pl. mucrones, mucros |
|
STRUCTURE |
|
A short, hard, apical point that is a continuation of vascular tissue. See also apiculum. |
|
bell-shaped |
= campanulate |
solid shape |
|
Circular in cross-section, inflated proximally, thence broadening gradually to a flared distal portion. |
|
ovule |
|
STRUCTURE |
|
A complex reproductive structure borne by a seed-plant sporophyte, consisting of outer, sporophytic tissues that enclose a haploid, gametogenic tissue usually regarded as a highly reduced megagametophyte. Following fertilization, the entire structure matures to become a seed that contains an embryo, the first stage of the next sporophytic generation. Ovules (and seeds) are borne naked on megasporophylls (in Pinophyta) or within an ovary (in Magnoliophyta). |
