orientation |
|
Curving abaxially. See also incurved. |
bulbil |
= bulblet |
STRUCTURE |
|
A small bulb-like structure produced from a sterile or fertile plant structure other than a bulb, usually within a leaf axil, leaf sinus, or inflorescence, serving as a vegetative propagule. |
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). |
cell 2 (not recommended) |
= chamber (not recommended), locule |
FEATURE |
|
Any structurally distinct compartment within an anther, ovary, fruit, sporangium or other organ; not necessarily having any evolutionary integrity. |
foliar |
|
insertion |
|
Upon or otherwise directly associated with the leaves. |
hypanthium 1 (broad sense) pl. hypanthia |
= floral cup (broad sense), floral tube |
STRUCTURE |
|
A complex structure comprising fused portions of the perianth and/or androecium of a flower, sometimes also including receptacular tissue; surrounding and wholly, partly, or not at all adnate to the gynoecium; subdivided morphologically into casing, collar and/or neck; sometimes bearing free distal portions of the constituent structures. |
strombuliform |
= spire-shaped |
solid shape |
|
Attenuate-spiral in three dimensions, the coils contiguous or not. |
radial |
= radiant, radiate, stellate |
arrangement |
|
Disposed about and mutually divergent from a common geometric center in two or three dimensions, thus collectively actinomorphic. |
mono… |
= one-…, single-…, uni… |
prefix |
|
Indicating presence of or constitution by one entity of the type denoted by the term's stem; as in monandrous, monocolpate, monocyclic. See also entries for particular terms with this prefix whose meanings, at least in some applications, are more specific than usually indicated by such combination. |
verticillate |
= cyclic, seriate, whorled |
arrangement |
|
Disposed along the axis in groups of three or more, the members of each group (cycle, series, verticil, whorl) inserted regularly around the axis at the same level. |
column 2 |
|
STRUCTURE |
|
A fused androecium (connate stamens) closely surrounding but free from the gynoecium; esp. in Malvaceae. |
…gonal |
= …angular |
plane shape |
|
Having more or less straight sides of the number indicated by the prefix; as in pentagonal, trigonal. See also deltate, …gonous (…angled). |
spicule |
|
STRUCTURE |
|
A small, fine, stiff, acute protrusion that resembles a little spike. |
botuliform |
= sausage-shaped |
solid shape |
|
Arcuately cylindric with rounded ends. |
erose 1 |
|
margin |
|
Having rough, very irregular depressions throughout. |
rootstock |
= rhizome |
STRUCTURE |
|
An underground, usually horizontal stem, often superficially resembling a root but easily distinguished by the presence of nodes, from which it branches exogenously to produce the aboveground portion(s) of the shoot. |
oblong 1 |
|
plane shape |
|
Compressed-elliptic, the sides approximately parallel from near one end to near the other. See also elliptic(al) (oval). |
crescent-shaped |
= lunate |
plane shape |
|
Arcuate, broadest at the middle, and attenuate to acute ends; like the stylized outline of a first-quarter moon. |
stipe 1 |
< stalk |
STRUCTURE |
|
A small, slender connection between a pollinium caudicle and a viscidium; in Orchidaceae. |
discoid 1 |
= disciform |
solid shape |
|
Relatively thin with two round, plane or convex, opposite broad faces and a rounded circumferential edge; like a disc. See also lenticular (biconvex, lens-shaped), meniscoid, placentiform (placenta-shaped), trochlear (pulley-wheel-shaped). |
pulley-wheel-shaped |
= trochlear |
solid shape |
|
Discoid (disciform) but with the circumferential surface concave between faces. |
seed coat |
= testa |
STRUCTURE |
|
The outer protective layer of a seed, developed from the ovular integument(s). |
geminate |
= conjugate, paired |
arrangement |
|
Inserted by pairs, the members of each fused or not. |
papilliform |
= papillar(y) |
solid shape |
|
Small, conoidal, and protruding from a larger structure; resembling a pimple; esp. trichomes. |
