radical |
|
insertion |
|
Upon, arising from, or otherwise directly associated with the root. |
elater 1 |
|
STRUCTURE |
|
An elongate cell with a helical, hygroscopic thickening in its wall, contained within a sporangium, expanding and contracting with changes in humidity and aiding dispersal of the spores; esp. in Hepaticae. |
caruncle |
= strophiole |
STRUCTURE |
|
An outgrowth from the seed coat (testa) around or near the hilum and micropyle, or from the raphe. |
fascicled 2 |
= bundled (not recommended), fasciculate |
arrangement |
|
Disposed in one or more fascicles, the members of each inserted close together and only slightly if at all divergent from one another. |
seed leaf |
= cotyledon |
STRUCTURE |
|
Any of the one or more primary foliar structures of an embryonic seed plant, proximal to all succeeding leaf primordia; sometimes serving as a storage organ for food reserves in the seed, as in peas and beans. |
laminar 2 |
|
solid shape |
|
Relatively very thin with parallel opposite broad faces, the whole plane or variously curved. Structures to which this term, along with any other three-dimensional ones, is applicable are often also described as though only two-dimensional, using terms that are implicitly understood to refer only to the outline of the broad faces. |
…furrowed |
= …colpate, …fossulate, …grooved, …sulcate, …valleculate |
architecture |
|
Having the number of furrows indicated by the prefix; as in five-furrowed, 3-furrowed. |
goblet-shaped |
= crateriform |
solid shape |
|
Having a distal, concave, relatively thin-walled, basically hemispherical portion surmounting a much narrower, transversely round, pedestal-like base. |
diffuse-porous |
|
porosity |
|
Homogeneously porous, the vessels not differentially disposed by size or number. |
neck (floral tube) |
|
STRUCTURE |
|
The solid, usually constricted portion of a floral tube sometimes present between casing and collar when those are both present. |
lineolate 1 |
|
coloration |
|
Finely lineate, the lines short and often irregularly oriented. |
inflorescence 1 |
|
architecture |
|
Mode or progressive pattern of bearing flowers; most appropriately described using adjectival terms. |
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). |
herbaceous 2 |
|
texture |
|
Composed entirely of relatively soft, non-woody (unlignified) tissues derived from primary growth. |
punctate 1 |
= dotted |
coloration |
|
Having small, round, clear or colored spots that contrast with the ground color. See also puncticulate (small-dotted). |
prolate |
|
plane shape |
|
Symmetrically elongate parallel to the developmental or polar axis. |
stomium pl. stomia |
= stomatal pore |
FEATURE |
|
The opening in the wall of a sporangium, between the lip cells, through which the spores exit; in Psilotophyta, Lycopodiophyta, Equisetophyta, Polypodiophyta. |
ampulla pl. ampullae |
= bladder |
STRUCTURE |
|
A small, membranous, hollow, flask-shaped, insectivorous structure borne on a submerged leaf; esp. in Lentibulariaceae. |
scalloplet |
= crenule |
FEATURE |
|
A diminutive scallop (crena). See also sawtooth, sawtoothlet, tooth (dens), toothlet. |
revolute 1 |
|
margin |
|
Rolled inward abaxially. |
knee 1 |
|
STRUCTURE |
|
An abrupt bend in an axial or other elongate structure. |
…fossulate |
= …colpate, …furrowed, …grooved, …sulcate, …valleculate |
architecture |
|
Having the number of fossulae indicated by the prefix; as in unifossulate, multifossulate, 5-fossulate. |
geminate |
= conjugate, paired |
arrangement |
|
Inserted by pairs, the members of each fused or not. |
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. |
barbel |
= barbella |
STRUCTURE |
|
A small barb. |
