|
fibrous root |
< diffuse root |
STRUCTURE |
|
A diffuse root that includes a significant component of woody or sclerotic strands and is consequently tough and often wiry. |
|
scallop |
= crena |
FEATURE |
|
A rounded, marginal convexity or concavity in a series of such that alternate regularly and are oriented more or less perpendicular to the generalized perimeter of a laminar structure. See also sawtooth, sawtoothlet, scalloplet (crenule), tooth (dens), toothlet. |
|
staminal |
|
position |
|
Upon or otherwise directly associated with the stamens. |
|
subsidiary cell |
|
STRUCTURE |
|
One of the cytologically distinctive epidermal cells that are sometimes present in a stomate and that surround and are regularly oriented in relation to the guard cells. |
|
prophyllar |
|
insertion |
|
Upon or otherwise directly associated with the prophylls (bracteoles, bractlets). |
|
elaiosome |
|
STRUCTURE |
|
A fleshy outgrowth from the seed coat (testa) that contains a high proportion of oil, usually attracting ants for dispersal. |
|
main stem |
= primary stem; > bole, trunk |
STRUCTURE |
|
The one, or any of the more than one, first-order stem(s), or first-order portion(s) of the collective stem, of a shoot. |
|
cladodromous |
|
venation |
|
Having a single median primary vein that branches to either side along its length, the secondary veins running thence toward the margin, but freely ramifying and becoming indistinct before reaching it. |
|
male |
= masculine |
reproduction |
|
Of the sex that produces microspores and sperm. |
|
cladophyll |
= cladode, phylloclade |
STRUCTURE |
|
A stem segment that functions as a leaf; often more or less compressed. |
|
unciform |
= hook-shaped |
solid shape |
|
Very slenderly elongate with a more or less straight proximal portion and a recurved terminal portion, the whole resembling a hook. |
|
full |
|
extent |
|
Reaching from the ovary wall or pericarp to the center of the ovary or fruit and from the apex to the base of its interior, thus separating adjacent locules completely. |
|
showy |
< conspicuous |
manifestation |
|
Prominently evident and attractive due to size, shape and/or coloration. |
|
derivation |
|
CHARACTER |
|
Ontogenetic origin. |
|
peripheral |
|
position |
|
Upon or otherwise directly associated with the outer surfaces or regions of a three-dimensional structure. Although use of this term in two-dimensional contexts is technically correct, traditionally the term marginal is preferred in such cases. |
|
lacrimate |
= teardrop-shaped |
plane shape |
|
Like the stylized lateral outline of a teardrop; broadest just below the middle, broadly rounded to the base, and acutely attenuate to the apex; like the stylized lateral outline of a teardrop. |
|
eyespotted |
= ocellate |
coloration |
|
Having a more or less circular area that differes in hue and/or intensity from the remainder of the structure; esp. a corolla with such an area at its center. |
|
muticous |
|
apex |
|
Lacking a distinct terminal point (when one might be expected). |
|
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. |
|
weak |
|
texture |
|
Very pliable and unresilient. |
|
aril 2 (strict sense) |
= arillus |
STRUCTURE |
|
An appendicular structure that wholly or partly envelops a seed and is an outgrowth from the funicle or raphe, and thus is ontogenetically derived from the placenta; usually fleshy or pulpy, sometimes spongy or tufted-capillate, often brightly colored. |
|
hair |
= capillus; > glochid, glochidium; < cilium, trichome |
STRUCTURE |
|
A hair-like trichome. |
|
sporophyte |
|
PLANT |
|
The main, ultimate, spore-bearing stage in the diploid (2n chromosomes) phase of a taxon's life cycle. Two morphologically and genetically distinct and alternate phases together constitute the complete life cycle in sexually reproducing taxa, the other phase (gametophytic) being haploid (n chromosomes). Any taxon whose life cycle is confined to one or the other phase is limited to asexual means of reproduction, since sexual reproduction with consequent genetic recombination is impossible without alternation between haploid and diploid states via meiosis and fertilization. The term sporophytic applies to any part of the diploid phase, including all unicellular to multicellular entities belonging to it, whereas sporophyte is reserved for the principal and directly spore-producing stage of that phase. |
|
lobe |
? division, segment |
STRUCTURE |
|
Any generally convex, major peripheral protrusion or component sector that is delimited by concavities in the surface or margin and that is not proximally distinct from the remainder of the whole. |
|
tubiform |
= trumpet-shaped |
solid shape |
|
Obteretely tubular with a relatively short distal flare (the limb if a perianth, calyx, or corolla). |
