costal |
|
insertion |
|
Upon or otherwise directly associated with the costa(e) of a laminar structure. |
|
flattened |
> complanate, compressed, depressed, obcompressed |
solid shape |

|
stipule scar |
|
FEATURE |
|
A scar on a stem or petiole due to abscission of a stipule; having an outline like that of a transverse section through the base of the stipule inserted there; variously disposed, usually in pairs, adjacent to a point of leaf insertion, sometimes confluent with the leaf scar, sometimes confluent with stipule scars associated with an opposite leaf, the two sets of scars then more or less encircling the axis. |
|
dissected |
? cleft, divided, lobate, lobed, parted, partite, segmented |
plane shape |
|
Having two or more component sectors or peripheral protrusions that are delimited by concavities in the surface or margin and that are not proximally distinct from the remainder of the whole. The meanings of this term and its approximate synonyms sometimes have been supposed to differ according to the depth of the delimiting concavities relative to the midline or midpoint of the overall structure, and/or to the shape or proportions of the protusions or sectors; however, there has been little consistency in the applications of the various terms according to such distinctions, which are ones only of degree and are necessarily arbitrary in any case. In general usage, these terms differ only indistinctly and connotatively: cleft, lobed (or lobate), parted (or partite) and segmented tend to connote fewer protrusions or sectors; lobate usually connotes as well a generally rounded shape; dissected tends to connote more numerous sectors that are elongate and angular. See also cut (incised, lacerate, torn), laciniate (slashed). |
|
pulvinus pl. pulvini |
|
STRUCTURE |
|
A short, cushion-like swelling at the junction of stem and leaf or of inflorescence axis and branch. |
|
circumcaulous |
|
insertion |
|
Upon and surrounding the stem. |
|
triple-… |
= thrice-…, tri-… |
prefix |
|
Indicating presence of three hierarchical orders of the type of entity or pattern denoted by the term's stem; as in triple-palmate. See also three-…. |
|
megastrobilus pl. megastrobili |
= female cone, macrostrobilus (not recommended) |
STRUCTURE |
|
A strobilus (cone) whose fertile organs are all megasporophylls. |
|
valvate 1 |
|
aestivation |
|
Whorled and with members not overlapping, adjacent members laterally contiguous at their margins. |
|
segmented |
? cleft, dissected, divided, lobed, lobate, parted, partite |
plane shape |
|
Having two or more major component sectors or peripheral protrusions that are delimited by concavities in the surface or margin and that are not proximally distinct from the remainder of the whole. The meanings of this term and its approximate synonyms sometimes have been supposed to differ according to the depth of the delimiting concavities relative to the midline or midpoint of the overall structure, and/or to the shape or proportions of the protusions or sectors; however, there has been little consistency in the applications of the various terms according to such distinctions, which are ones only of degree and are necessarily arbitrary in any case. In general usage, these terms differ only indistinctly and connotatively: cleft, lobed (or lobate), parted (or partite) and segmented tend to connote fewer protrusions or sectors; lobate usually connotes as well a generally rounded shape; dissected tends to connote more numerous sectors that are elongate and angular. See also cut (incised, lacerate, torn), laciniate (slashed). |
|
germination 2 |
|
CHARACTER |
|
The process wherein the contents of a spore begin active growth, exiting the confines of the spore wall via a pore or crack and giving rise to a gametophyte. |
|
papyraceous |
= chartaceous, papery |
texture |
|
Very thin, flexible, and readily torn; like paper. See also membranaceous (membranous), pergamentaceous (parchment-like). |
|
crisped |
= crispate, curly |
margin |
|
Having closely and irregularly spaced, irregularly shaped, often compound convexities that curve irregularly through three dimensions. |
|
internodal |
|
position |
|
Upon or otherwise directly associated with the internodes. |
|
suprafoliar |
|
insertion |
|
Upon the stems, each directly above (distal to) and very near a point of leaf insertion. |
|
biconvex 2 |
= lens-shaped, lenticular |
solid shape |
|
Relatively thin with two round, convex, opposite broad faces intersecting acutely at the circumferential edge; like a double-convex lens. See also disciform (discoid), meniscoid. |
|
epicotyl |
= plumule |
STRUCTURE |
|
A distinguishable nascent shoot developed in the embryo in some taxa, consisting of a shoot axis with unexpanded internodes and one or more leaf primordia, being that portion of the embryo above the level of cotyledon insertion; the primordial shoot, when developed by the embryo within a seed; the first bud of a spermatophyte, when developed by an embryo within the seed. In other taxa the shoot is represented in the embryo only by a quiescent apical meristem at the summit of the embryonic axis. |
|
contortuplicate 1 |
= torsive |
aestivation |
|
Plicate and contorted. |
|
nodulose |
|
solid shape |
|
Diminutively nodose; esp. roots of Fabaceae (Leguminosae), the nodules harboring nitrogen-fixing bacteria. |
|
soft |
|
texture |
|
Yielding under slight pressure. |
|
helical 3 |
= spiral |
course |
|
Curving with constant or regularly increasing radius from one end to the other through three dimensions. |
|
acrodromous |
|
venation |
|
Having two or more primary and/or strongly developed secondary veins that diverge at or above the laminar base and are thence convergently arcuate toward the apex, reaching it or not. |
|
…-toothed 1 |
= …dentate |
apex |
|
Generally truncate but with the number of antrorse, attenuate, distal lobes indicated by the prefix; as in three-toothed. |
