FEATURE |
|
A sequence of lateral structures arising from the same axis at successive points along its length and diverging from it in the same direction. |
|
epiphyllous |
|
insertion |
|
Upon the leaves, or partially adnate thereto and apparently arising therefrom. |
|
scale 1 |
< bract |
STRUCTURE |
|
A basically dry, more or less appressed, diminutive bract. The choice of term as between the more general bract and the more restricted scale is sometimes problematic and, when so, often is dictated by custom according to the structure and taxon involved. |
|
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.). |
|
smooth 1 |
|
relief |
|
Even or unrelieved overall. Strictly applied, this term refers only to the surface proper; however, it is often used to mean glabrous as well. |
|
stomatal pore 1 |
= stoma (strict sense) |
FEATURE |
|
The opening between and regulated by the two guard cells of a stomate (stomatal apparatus). |
|
indumentum pl. indumenta var. indument |
= vesture |
STRUCTURE / SUBSTANCE |
|
The trichomes and/or exuded substance that overlie a surface proper, regarded collectively. See also coating, pubescence. |
|
teardrop-shaped 2 |
= lacrimiform |
solid shape |
|
Transversely round and broadest just below the middle, broadly rounded to the base and acutely attenuate to the apex. |
|
leathery |
= coriaceous |
texture |
|
Moderately thick, tough, and very pliable. |
|
umbo pl. umbines, umbos |
|
FEATURE |
|
A relatively small, rounded or conical, central protrusion upon an essentially round, broad face. |
|
zoned |
|
coloration |
|
Having two or more fairly distinctly delineated areas of contrasting hues and/or intensities. |
|
absent |
|
presence |
|
Not occurring within the context in point. |
|
apiculum 2 pl. apicula |
|
STRUCTURE |
|
The apex of a connective, when prolonged above the union of the anthers. |
|
caudate 2 |
= tailed |
base |
|
With one or more relatively slender, retrorse basal enations or appendages. |
|
connective |
|
STRUCTURE |
|
The tissue between and joining the laterally opposed thecae of an anther, connecting them with the distal end of the staminal filament when the latter is present. |
|
pit |
= fovea, scrobis |
FEATURE |
|
A small, rounded depression. |
|
dehiscent |
|
dehiscence |
|
Splitting or forming one or more apertures at maturity, the contents thereby released for dispersal. |
|
pyrene 1 |
= stone |
STRUCTURE |
|
The hard inner portion of a drupe, consisting of osseous endocarp and included seed. |
|
embryo sac |
< megagametophyte |
STRUCTURE |
|
The multinucleate generative cell of an ovule, within which fertilization and zygote formation occur; resulting from meiotic division of a megaspore mother cell within the nucellus, and thus genetically haploid; its contents generally considered to represent an evolutionarily reduced gametophyte. |
|
runner |
= stolon |
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. |
|
five-… |
= penta… |
prefix |
|
Indicating presence of or constitution by five entities of the type denoted by the term's stem; as in five-grooved, five-stamened, five-tepaled. |
|
glutinous 1 |
> mucilaginous, mucous, viscid |
coating |
|
Of a sticky or slimy substance. |
|
star-shaped 1 |
= stellate |
plane shape |
|
Having four or more intersecting radiate lobes or portions, each distally slender; like the stylized outline of a star. |
|
hyphodromous |
= one-veined, single-veined |
venation |
|
Having one median, primary vein and no other venation externally evident. |
|
lamina 2 pl. laminae |
= ray |
STRUCTURE |
|
The distal, relatively flat portion of the zygomorphic corolla of a ray floret, terminating in 0--4 teeth or lobes; in Asteraceae (Compositae). |
