peripheral |
|
position |
|
Upon or otherwise directly associated with the outer surfaces or regions of a three-dimensional structure. Although use of this term in two-dimensional contexts is technically correct, traditionally the term marginal is preferred in such cases. |
|
ephemeral |
|
duration |
plant |
Annual with a very short life span; germinating, growing, reproducing, and dying within a brief period of favorable conditions, the entire cycle being completed within a few weeks. |

architecture |
inflorescence |
Comprising one or more anthelae; esp. in Juncaceae. |
|
symmetric(al) 1 |
|
architecture |
|
Divisible into essentially equal halves along one or more lines or planes. |
|
cotyloid |
|
architecture |
flower |
Having general adnation among the different sets of floral structures, thus having the ovary inferior and/or having a floral tube. |

A hole or cavity; an empty space surrounded by tissue in two or three dimensions. |
|
erose 1 |
|
margin |

habit |
plant |
Growing in water. |
|
gynandrous |
|
architecture |
flower |
Having the androecium adnate to the gynoecium. |
|
tepal |
|
STRUCTURE |
|
Any member of an undifferentiated perianth; may be green and foliaceous or colored and petaloid, distinct or else connate with one or more others, and/or free or else adnate with one or more other floral structures. |
|
cryptic |
|
coloration |
|
Similar to its natural background, from which it is not readily distinguished. |
|
centrifugal |
|
development |
|
Proceeding away from the center, thus more advanced centrally than peripherally within a given frame of reference. |
|
spur 1 |
|
STRUCTURE |
|
A hollow protrusion from a calyx or corolla, often nectariferous. |
|
obdiplostemonous |
|
architecture |
flower, androecium |
Having the stamens dicyclic, the proximal whorl with members directly above the petals, the distal whorl with members directly above the sepals. See also diplostemonous. |
|
throat 2 |
|
STRUCTURE |
|
The fully connate portion of the limb of a disc floret, proximal to the lobes (distinct distal portions of the petals); in Asteraceae (Compositae). |
|
cypsela pl. cypselae |
|
nominative |
fruit |
Like an achene but derived from an inferior, bicarpellate ovary and with accessory perianth tissue adnate to the pericarp; esp. in Asteraceae (Compositae). |
|
circinate 2 |
|
vernation |
|
Having each leaf (frond) rolled adaxially from the sides and downward from the apex, forming a tight, flat coil; esp. in Polypodiophyta. |
|
ligule 1 |
|
STRUCTURE |
|
A strap-shaped enation from or distal portion of a structure. |
|
position |
|
CHARACTER |
|
Location or disposition with reference to some dissimilar structure(s) or larger context. The lexicons relating to position and insertion overlap to a great degree, since these two morphological concepts are often inseparable in practice. Also overlaps conceptually with arrangement, habit, orientation, and shape. |
|
odorless |
|
odor |
|
Lacking a distinct odor. |
|
tree |
|
nominative |
plant |
Perennial, woody, more or less erect, relatively tall, with one or more distinct aboveground portions each with a single, relatively stout, columnar, main stem (trunk or bole) that bears branches. See also bush, frutex, shrub, subshrub, suffrutex, undershrub, woody clump. |
|
secondary root |
|
STRUCTURE |
|
Any root branch that originates directly or indirectly from a primary root. |
|
disc floret |
|
STRUCTURE |
|
A floret that has an actinomorphic corolla, is bisexual, functionally staminate, or functionally pistillate, and is borne in a radiate, discoid, disciform, or radiant capitulum (head) interior (distal) to any peripheral series of differing florets that may be present; in Asteraceae (Compositae). |
|
aciculate |
|
coloration |
|
Having fine, irregularly oriented, straight streaks of contrasting hue and/or intensity. |
|
floating 2 |
