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. |
|

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. |
|
multiciliate |
|
architecture |
|
Having several to many cilia. |
|
synangium pl. synangia |
|
STRUCTURE |
|
A compound sporangium; an aggregation of coherent sporangia, the whole multilocular. |
|
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). |
|
lamella pl. lamellae |
|
STRUCTURE |
|
A thin layer of tissue that forms a plate within tissue of lesser density or between areas of empty space. |
|
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. |
|
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. |
|
oblique 1 |
|
apex |
|
Asymmetric about its longitudinal axis. |
|
tiller |
|
STRUCTURE |
|
An erect or ascending stem that branches from the base of another at or below the surface of the ground; esp. in Poaceae (Gramineae) and other monocotyledons (Liliidae). |
|
asymmetric(al) 1 |
|
architecture |
|
Not divisible into essentially equal halves along any line or plane. |
|
present |
|
presence |
|
Occurring within the context in point. |
|
decompound |
|
architecture |
|
Comprising two or more orders of equivalent substructural entities; multiply compound. |
|
limb 1 |
|
STRUCTURE |
|
A relatively broad portion of a syntepalous (gamotepalous) perianth, synsepalous (gamosepalous) calyx, or sympetalous (gamopetalous) corolla distal to a narrower tube, spreading outward or ascending from the tube, comprising the distinct or connate distal portions of the tepals, sepals, or petals; except in bisexual or staminate disc florets of Asteraceae (Compositae). |
|
prickle |
|
STRUCTURE |
|
Any unvascularized spine-like enation originating in the epidermis, cortex, or mesophyll of any shoot part. See also spine, thorn. |
|
hip |
|
nominative |
fruit |
Aggregate and consisting of several to many achenes enveloped by a free, urceolate, more or less fleshy, accessory structure derived from floral tube tissue; esp. in Rosa (Rosaceae). |
