|
Upon, arising from, or otherwise directly associated with the stem. |
|
indeterminate |
|
development |
|
Having the lateral (peripheral, basal, or proximal) portions differentiating first and the terminal (central, apical, or distal) portion later, development thus proceeding sequentially upward or inward. |
|
indument |

|
isthmus |
|
STRUCTURE |
|
A narrower portion connecting two wider or broader portions of an inclusive structure. |
|
silicle |
|
nominative |
fruit |
Like a silique, but only slightly longer than broad to broader than long; esp. in Brassicaceae (Cruciferae), Capparaceae. |
|
spinescent |
|
architecture |
|
Becoming spinose. |
|
corolla pl. corollae, corollas |
|
STRUCTURE |
|
Collectively, the petals of a flower, whether distinct or connate; the inner or distal envelope of a differentiated perianth, whether the other envelope (calyx) is actually present or is deemed to be absent due to evolutionary reduction. |
|
staminodial |
|
position |
|
Upon or otherwise directly associated with the staminodes. |
|
cymulose |
|
architecture |
inflorescence |
Comprising one or more cymules. |
|
subtending |
|
position |
|
Arising from the axis just below and very near to the base of some other specified lateral structure. This term is meaningless if the structure that is subtended is not indicated. |
|
biennial 1 |
|
duration |
plant, stem |
Normally living two years; germinating or forming and growing vegetatively during one cycle of seasons, then reproducing sexually and dying during the following one. |

Upon the axes, each directly above (distal to) and very near a point of bract insertion. |
|
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). |
|
excurrent |
|
architecture |
axis, laminar vein |
Branching laterally such that the initial axis retains its prominence over the length of the structure, the succesive orders of branches relatively smaller. See also deliquescent. |
