septal |
|
position |
|
Upon or otherwise directly associated with the septum or septa. |
|
dorsiventral |
|
architecture |
|
Having structurally distinct abaxial (dorsal) and adaxial (ventral) portions or aspects. |
|
aestivation |
|
CHARACTER |
|
Disposition of perianth (undifferentiated), calyx, or corolla members in the bud. |
|
marginal |
|
insertion |
|
Upon or otherwise directly associated with the margins. |
|
shoot 2 |
|
STRUCTURE |
|
A vascularized axis that is differentiated into nodes and internodes and that branches exogenously from the former, together with any non-axial structures borne from it. |
|
vallecular |
|
insertion |
|
In or otherwise directly associated with the valleculae; esp. in fruits of Apiaceae (Umbelliferae). |
|
elaiosome |

STRUCTURE |
|
A fleshy outgrowth from the seed coat (testa) that contains a high proportion of oil, usually attracting ants for dispersal. |
|
microphyllous |
|
architecture |
plant |
Bearing microphylls. |
|
isopetalous |
|
architecture |
flower, perianth, corolla |
Having the petals essentially alike in size and shape. |
|
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. |
|
anthelate |
|
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. |
|
lacuna pl. lacunae |
|
FEATURE |
|
A hole or cavity; an empty space surrounded by tissue in two or three dimensions. |
|
tendril |
|
STRUCTURE |
|
A slender stem branch, modified leaf, or portion of a leaf that twines about a supporting structure. |
|
centralium pl. centralia |
|
FEATURE |
|
A central longitudinal cavity within the seed; esp. in Arecaceae (Palmae). |
|
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. |
