collateral |
|
position |
buds |
In pairs within or immediately straddling the leaf axils, the members of a pair lateral to one another. |
|
brachiate |
|
architecture |
axis |
Having alternate, divaricate branches. |

dehiscence |
|
Not splitting or forming an aperture at maturity, the contents being released for dispersal only after decay, digestion, or erosion of the structure. |
|
pappose |
|
architecture |
flower, fruit |
Bearing a pappus; esp. in Asteraceae (Compositae). |
|
…seriate 1 |
|
architecture |
trichome |
Multicellular with the number of longitudinal columns of superposed cells indicated by the prefix; as in biseriate, multiseriate, uniseriate. |
|
free-central |
|
placentation |
|
Upon the free axial column of a compound, unilocular ovary. |
|
subpetiolar |
|
position |
|
Just below the point of petiole insertion. |
|
internodal |
|
insertion |
|
Upon or otherwise directly associated with the internodes. |
|
peltate |
|
architecture |
foliaceous structure |
Petiolate with the petiole attached to the abaxial face of the blade at some point within the margin and otherwise free from the blade. |
|
valvate 4 |
|
dehiscence |
fruit |
With longitudinal segments of the wall (valves) separating partly or wholly from one another, spreading outward from the base or apex, and sometimes falling away. |
|
ellipsoid(al) |
|
solid shape |
|
Elliptic in any median longitudinal section; elongate, transversely circular, broadest at the middle, and symmetrically convex-attenuate to rounded ends. See also oblong. |
|
gamophyllous |
|
architecture |
plant, shoot axis, involucre |
Having pairs or whorls of leaves or bracts that are connate at their edges. |
|
raphe |
|
STRUCTURE |
|
That portion of the funicle adnate to the integument of an anatropous ovule; represented by a longitudinal ridge or other discontinuity in the surface and/or color of the testa on one side of the mature seed. |
|
superior 1 |
|
insertion |
indusium |
Inserted at or near the apex of the sorus, distal to the sporangia. |
|
soft |
|
texture |
|
Yielding under slight pressure. |
|
vexillate |
|
aestivation |
|
Having a larger member oriented more or less perpendicular to and folded about the others. |
|
epidermal cell |
|
STRUCTURE |
|
Any of the unspecialized cells of an epidermis; i.e., any other than stomatal guard cells or cells directly associated with trichomes. While the latter specialized cells are also properly epidermal cells, they are treated separately for descriptive purposes and, for the sake of convenience, use of the general term is restricted to the unspecialized cells that constitute the bulk of an epidermis. |
|
anticlinal |
|
orientation |
|
Perpendicular to some given plane of reference; applied especially to the plane of cell division when it is oriented at right angles to the generalized plane of the structural surface. |
|
glomerulate |
|
architecture |
inflorescence |
Comprising one or more glomerules; esp. in Asteraceae (Compositae). |
|
multiciliate |
|
architecture |
|
Having several to many cilia. |
|
synangium pl. synangia |
|
STRUCTURE |
|
A compound sporangium; an aggregation of coherent sporangia, the whole multilocular. |
|
lamella pl. lamellae |
|
STRUCTURE |
|
A thin layer of tissue that forms a plate within tissue of lesser density or between areas of empty space. |
|
architecture |
|
CHARACTER |
|
Composite structural configuration as to type, orientation, symmetry, insertion, position, fusion, presence, number, relative size, shape, texture, differentiation, and/or derivation of components and features. Overlaps conceptually with habit. |
|
root 1 |
|
STRUCTURE |
|
Collectively, all those portions of a plant body that are anatomically distinct from the shoot, the component axes not differentiated into nodes and internodes, and branching endogenously. |
|
terminal |
|
position |
|
Apical and with the same developmental axis as the whole, of which it is the distalmost portion or appendage. |
