|
stellate 2 |
= star-shaped |
plane shape |
|
Having four or more intersecting radiate lobes or portions, each distally slender; like the stylized outline of a star. |
|
barbed 1 |
|
apex |
|
Terminated by a small, relatively stiff, acutely reflexed, hook-like structure. |
|
pith |
|
STRUCTURE |
|
The central ground tissue of a stem or, when present, of a root, consisting of thin-walled parenchyma cells; distinct and more or less soft and spongy relative to the other tissues of the axis; sometimes partly or wholly degenerating after secondary growth has begun. |
|
pseudoaxillary |
|
insertion |
|
Only apparently axillary; originally extraaxillary but displaced to the axil by differential growth during development. |
|
leftward |
= sinistrorse |
orientation |
|
Directed to the left, relative to the direction of growth along an explicit or implicit axis of reference. See also rightward (dextrorse). |
|
torus 2 pl. tori |
= receptacle |
STRUCTURE |
|
The short, expanded, compound axial structure surmounting a peduncle and basal to two or more flowers, or to the florets of a capitulum (head) in Asteraceae (Compositae), where it may bear paleae (receptacular bracts), scales, bristles, trichomes, or subulate enations, and may be smooth or variously pitted (alveolate, foveolate). |
|
firm |
|
texture |
|
Yielding under only moderately strong pressure; only slightly deformable without internal structural disruption. |
|
pallid |
|
coloration |
|
Relatively pale; not strongly colored. |
|
inflated |
|
solid shape |
|
Relatively thin-walled with an essentially empty interior largely enclosed by the walls, which are convex overall and appear taut, as though from internal pressure. See also swollen (turgid, tumid), which is not clearly distinct in its application. |
|
bulb |
|
STRUCTURE |
|
A thickened underground perennating structure consisting of a stem with numerous closely proximate nodes bearing many tightly imbricate, thickened, often fleshy, foliaceous organs containing large amounts of stored food, usually in the form of starch; the whole usually enveloped and protected by imbricated scarious or fibrous foliaceous organs. |
|
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. |
|
remote |
= distant |
arrangement |
|
Disposed relatively far from one another along the axis. |
|
masculine |
= male |
reproduction |
|
Of the sex that produces microspores and sperm. |
|
unilateral 1 |
= one-sided |
architecture |
|
Having only one side, as compared with presumably equivalent, bilaterally symmetric structures. |
|
neck (floral tube) |
|
STRUCTURE |
|
The solid, usually constricted portion of a floral tube sometimes present between casing and collar when those are both present. |
|
fusiform |
= spindle-shaped |
solid shape |
|
Elongate, transversely round, broadest at the middle and regularly attenuate to either end. |
|
concolor(ous) |
|
coloration |
|
Uniform in hue and intensity of color; esp. leaves with identically colored adaxial and abaxial surfaces. |
|
asymmetric(al) 1 |
|
solid shape |
|
Not divisible into essentially equal halves along any line or plane. |
|
petiole |
< stalk, stipe (broad sense, not recommended) |
STRUCTURE |
|
The stalk, when present, of a leaf. |
|
laminar 1 |
|
position |
|
Upon or otherwise directly associated with the lamina (blade) of a foliaceous structure. |
|
thallus 1 pl. thalli |
|
STRUCTURE |
|
The vegetative portion of a shoot when not differentiated into stem and leaves; esp. in Lemnaceae. |
|
sarcous |
= carnose, fleshy |
texture |
|
Fairly firm and dense, juicy or at least moist, and easily cut. |
|
ala 1 pl. alae |
= wing |
STRUCTURE |
|
Any elongate, relatively thin protrusion or appendage. |
|
operculum pl. opercula |
= lid |
STRUCTURE |
|
A distal, cover-like portion of a structure whose main body is otherwise closed, transversely discontinuous with the main body around most of the circumference, or becoming partially or wholly separate by transverse dehiscence; as of an ascidium (pitcher), pollen grain, pyxis, or sporangium (spore case). |
|
squamose |
= lepidote, squamate; < scaly |
pubescence |
|
Bearing squamae (lepides). See also squamellose. |
