septicidal |
|
dehiscence |
fruit |
Splitting longitudinally into or through the suture(s) in the outer wall and, if present, through the septum(-a) between locules, the latter thus opened indirectly to the outside. |
|
paniculate |
|
architecture |
inflorescence |
Comprising one or more panicles. |
|
ocrea pl. ocreae var. ochrea |
|
STRUCTURE |
|
A tubular sheath that encircles a stem at a node, subtending a petiole; thought to have arisen evolutionarily by lateral fusion of two stipules; in Polygonaceae. |
|
cymose |
|
architecture |
inflorescence |
Comprising one or more simple or compound cymes. See also cincinnate, cymulose, dichasiate, helicoid-cymose, monochasiate, rhipidiate, scorpioid-cymose. |
|
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. |
|
insertion |
|
CHARACTER |
|
Mode or locus of attachment of a structure to some dissimilar bearing structure. The lexicons relating to insertion and position overlap to a great degree, since these two morphological concepts are often inseparable in practice. Also overlaps conceptually with arrangement, habit, orientation, and shape. |
|
dull |
|
reflectance |
|
Reflecting only a low proportion of incident light, with no apparent sheen. |
|
monochlamydeous |
|
architecture |
flower |
Having a monocyclic perianth. |
|
ribbed 2 |
|
solid shape |
|
Having two or more prominent, elongate, relatively narrow, essentially parallel protrusions that extend over all or most of its length or circumference. |
|
discoid 2 |
|
architecture |
capitulum (head) |
Bearing florets that all have actinomorphic corollas and that are all bisexual, or all functionally staminate, or all functionally pistillate; in Asteraceae (Compositae). |
|
isosepalous |
|
architecture |
flower, perianth, calyx |
Having the sepals essentially alike in size and shape. |
|
nodule |
|
STRUCTURE |
|
A small nodiform (gongylodate, gongyloid, knob-shaped, knot-shaped) segment or protrusion; esp. in roots of Fabaceae (Leguminosae) and harboring nitrogen-fixing bacteria. |
|
angular |
|
plane shape |
|
Having sides that meet at acute or obtuse angles. |
|
calyx tube |
|
STRUCTURE |
|
A relatively narrow, fully connate portion of a synsepalous (gamosepalous) calyx proximal to a broader portion (limb) that comprises the distinct or connate distal portions of the sepals. |
|
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. |
|
inferior 1 |
|
insertion |
indusium |
Inserted at the base of the sorus. |
|
poricidal |
|
dehiscence |
|
Forming one or more apertures in the exterior wall, usually apically or sub-apically, through which the contents pass to the outside. |
|
villosulous |
|
pubescence |
|
Finely villose (shaggy, villous). |
|
sheathing 2 |
|
base |
laminar structure |
Terete or involute and closely enclosing the supporting axis for some distance above the point of insertion. |
|
gum |
|
SUBSTANCE |
|
A highly viscous and sticky exudate that becomes more or less elastic and/or deformably solid upon drying. Overlaps conceptually with latex. |
|
peltate |
|
architecture |
foliaceous structure |
Petiolate with the petiole attached to the abaxial face of the blade at some point within the margin and otherwise free from the blade. |
|
throat 2 |
|
STRUCTURE |
|
The fully connate portion of the limb of a disc floret, proximal to the lobes (distinct distal portions of the petals); in Asteraceae (Compositae). |
|
exsert(ed) |
|
position |
anther, style |
Protruding beyond the floral envelope. See also included. |
|
vascular |
|
insertion |
|
Upon or otherwise directly associated with the vasculature. |
|
floricane |
|
STRUCTURE |
|
A biennial or perennial stem after it has begun flowering, when that does not occur until at least its second season of growth; applied especially to the stems of brambles (Rubus spp.). |
