ligule 1 |
|
STRUCTURE |
|
A strap-shaped enation from or distal portion of a structure. |
scrotiform |
= scrotum-shaped |
solid shape |
|
Saccate (bag-, pouch- or sack-shaped) and somewhat swollen bilaterally in the distal portion; like a scrotum. |
bulla pl. bullae |
= blister, pustule |
FEATURE |
|
A relatively coarse, rounded protrusion or convexity. See also papilla. |
gynaecium |
|
STRUCTURE |
|
See gynoecium. |
perisperm |
|
STRUCTURE / SUBSTANCE |
|
A genetically diploid (2n chromosomes) nutritive tissue in a seed; containing stored carbohydrate and/or oil utilized by the embryo prior to and especially upon germination; derived from the nucellus. See also endosperm (albumen). |
arillode |
< aril (broad sense) |
STRUCTURE |
|
A "false" aril; an appendicular structure that wholly or partly envelops a seed and is produced from or a modification of the outer integument or (in some Pinophyta) a subtending involucre, but not from the funicle or raphe, and thus is not ontogenetically derived from the placenta; usually fleshy or pulpy, sometimes spongy or tufted-capillate, often brightly colored. |
acropetal |
|
development |
|
Proceeding toward the apex, thus more advanced basally or proximally than apically or distally within a given frame of reference. |
deca… |
= ten-… |
prefix |
|
Indicating presence of or constitution by ten entities of the type denoted by the term's stem; as in decandrous, decagynous, decalocular. |
pulviniform |
= cushion-shaped, mound-shaped, pulvinate |
solid shape |
|
Essentially round in transverse section, much broader than long or high, with a convex distal face that intersects either a more or less plane proximal face or, when the structure is sessile, its bearing surface. |
twelve-… |
= dodeca… |
prefix |
|
Indicating presence of or constitution by twelve entities of the type denoted by the term's stem; as in twelve-loculed, twelve-stamened, twelve-styled. |
…faced |
|
solid shape |
|
Having relatively large, flat or shallowly curved portions of the external surface that are bounded by more or less distinct angular discontinuities in that surface, of the number indicated by the prefix; as in three-faced. |
hyaline |
= pellucid; > translucent, transparent |
coloration |
|
Transmitting light uniformly. |
obovate |
|
plane shape |
|
Inversely ovate (egg-shaped). |
papilliform |
= papillar(y) |
solid shape |
|
Small, conoidal, and protruding from a larger structure; resembling a pimple; esp. trichomes. |
fringed |
= fimbriate |
margin |
|
Regularly divided into slender, closely adjacent, more or less flexible segments, or having protrusions that give the appearance of such division. See also fine-fringed (fimbrillate). |
internode |
|
STRUCTURE |
|
Any portion of a stem between two successive nodes. |
sawtoothed |
= serrate |
margin |
|
Having regularly spaced, angular convexities oriented at an acute angle to the generalized perimeter. See also scalloped (crenate), small-scalloped (crenulate), small-sawtoothed (serrulate), small-toothed (denticulate), toothed (dentate). |
barbellulate |
|
architecture |
|
Bearing one or more barbellules (barbellulae). |
bracteate |
= bracted |
architecture |
|
Bearing or subtended by one or more bracts. |
glittering |
= splendent |
reflectance |
|
Interruptedly glossy (laevigate, lustrous, polished, shining, shiny, and thus sparkling when viewed from changing angles. |
top-shaped |
= turbinate |
solid shape |
|
Broadly obovoid-obconic; like a spinning top. See also pear-shaped (pyriform), obturbinate. |
apiculate |
|
apex |
|
Terminating abruptly in a short, slender, angular tip that is not notably harder or stiffer than the main body of the structure. See also mucronate, mucronulate. |
prophyll(um) pl. prophylls, prophylla |
= bracteole, bractlet; < bract |
STRUCTURE |
|
A second- or higher-order bract within, and subtending some portion of, an aggregate branching structure, especially when subtending a flower. |
cuboid |
|
solid shape |
|
Generally but not strictly cubic; more or less equilaterally six-sided, each side basically square. |
laticiferous |
|
exudation |
|
Producing and exuding latex. |
