barbella pl. barbellae |
= barbel |
STRUCTURE |
|
A small barb. |
|
turgid |
= swollen, tumid |
solid shape |

arrangement |
|
Touching one another. |
|
cristate |

apex |
|
Having a laterally elongate, relatively thin, irregular or notched protrusion. |
|
subcircular |
= subround; suborbicular misapplied, subrotund misapplied |
plane shape |
|
Compressed circular or very broadly elliptic, only slightly longer than wide. |
|
epidermis pl. epidermides, epidermises |
|
STRUCTURE |
|
The anatomically distinct, outermost, living tissue that encloses and protects the other tissues of a plant organ or part, usually overlaid by an exuded waxy cuticle; resulting from primary growth, disrupted and shed as a consequence of secondary growth if that occurs; consisting mainly of cells not further specialized, otherwise including various types of more specialized cells associated with trichomes and stomates. |
|
jointed |
= articulate(d) |
architecture |
|
Elongate with one or more distinct, relatively narrow zones of demarcation between adjacent main portions of the whole, these joints (articulations) often thicker and sometimes sites of eventual abscission. |
|
radicle |
|
STRUCTURE |
|
The primary root, or its primordium, in an embryo; the portion of an embryo axis that develops into the root. |
|
bulblet |
= bulbil |
STRUCTURE |
|
A small bulb-like structure produced from a sterile or fertile plant structure other than a bulb, usually within a leaf axil, leaf sinus, or inflorescence, serving as a vegetative propagule. |
|
vexillum pl. vexilla |
= banner, standard |
STRUCTURE |
|
The relatively large, erect adaxial (upper) petal in a papilionaceous corolla. |
|
spinose 1 |
|
apex |
|
Terminating in a rigid, tapering, sharp continuation of the central primary vein. See also spinulose. |
|
acinaciform |
= scimitar-shaped |
solid shape |
|
Thin and moderately arcuate with two opposite, plane, broad faces, the degree of curvature increasing distally, thinnest at the convex edge, thicker toward the concave; like a scimitar blade. |
|
plicate 3 |
= plaited, pleated |
vernation |
|
Having alternately adaxial and abaxial lengthwise folds, resembling a closed fan. |
|
attenuate 1 |
= concave-tapered |
base |
|
Gradually diminishing in width or diameter toward the proximal end, the sides longitudinally concave. Corresponds with acuminate for apex shape. |
|
tapered |
= attenuate |
solid shape |
|
Gradually diminishing in width or diameter from one end to the other. |
|
filamentous |
|
texture |
|
Composed of filiform (thread-like) strands with no intervening tissue. |
|
ligule 2 |
|
STRUCTURE |
|
An adaxial, distal enation from a leaf sheath, especially in most grasses (Poaceae) and sedges (Cyperaceae); usually unitary and membranous, sometimes instead consisting of a row of ciliate processes. See also hastula. |
|
tapeworm-shaped |
= taeniate |
solid shape |
|
Slender, elongate, basically cylindric or compressed-cylindric with shallow, narrow, more or less regular constrictions along its length, the whole apparently segmented and straight or variously curved. |
|
filiform |
= thread-like |
solid shape |
|
Elongate and very slender, basically round in transverse section and of more or less uniform diameter, variously curved over its length or not. See also capillary (capillate, hair-like). |
|
ligule 3 |
|
STRUCTURE |
|
A relatively small, attenuate, membranous, laminar enation from the adaxial surface of a leaf near its base; in Selaginella, Isoetes. |
|
obtrulliform |
= obtrullate |
plane shape |
|
Inversely trulliform (trowel-shaped, trullate). |
|
stomatal apparatus |
= stomate, stoma (broad sense) |
STRUCTURE |
|
A localized functional epidermal unit consisting of a microscopic pore and two encircling specialized cells, the guard cells, which, through changes of turgor pressure in response to environmental conditions, regulate the size of the pore and thus the rates of transpiration and gas exchange through it; the whole surrounded or not by associated, cytologically distinctive epidermal cells, the subsidiary or accessory cells, which, when present, are regularly oriented in relation to it. |
|
elliptic(al) 2 |
= oval |
plane shape |
|
Elongate, widest at the middle, and symmetrically convex-attenuate to rounded ends. See also oblong. |
