|
complete |
|
architecture |
flower |
Having all sets of basic floral structures (calyx and corolla, or else undifferentiated perianth; androecium; and gynoecium) present and functionally normal. |
|
scorpioid cyme |
|
nominative |
inflorescence |
A cyme in which each axial segment branches to only one side, the successive segments branching alternately to either side, the whole appearing to have a continuous, elongate, straight to zig-zag main axis. See also cincinnus, helicoid cyme (bostryx). |
|
funicular |
|
derivation |
aril |
Produced from or a modification of the funiculus (funicle). |
|
dichasiate |
|
architecture |
inflorescence |
Comprising one or more simple or compound dichasia. See also cincinnate, cymose, cymulose, helicoid-cymose, monochasiate, scorpioid-cymose. |

|
solid shape |
|
Constricted in width or breadth at or near the middle of its length. |
|
epibracteal |
|
position |
|
Upon the bracts, or partially adnate thereto and apparently arising therefrom. |

apex |
|

arrangement |
bundle scars |
Forming an incomplete ellipsis, like the letter U. |
|
plicate 1 |
|
aestivation |
|
Valvate with each member strongly infolded longitudinally. |
|
oil-secreting |
|
exudation |
|
Producing and exuding an oily substance, often aromatic; when oil-secreting glands are indicated in the nominative, often they are called simply oil glands. |
|
sap |
|
SUBSTANCE |
|
Generally, the fluid content of a plant body; more precisely, the sugary fluid transported by the phloem. |
|
siliceous |
|
texture |
epidermis, trichome |
Containing deposits of silica, thus hardened and abrasive. |
|
laevigate 1 |
|
relief |
|

|
deliquescent 2 |
|
texture |
|
Delicately fleshy and liquifying at maturity or with pressure; e.g., petals of Tradescantia (Commelinaceae). |
|
costal |
|
position |
|
Upon or otherwise directly associated with the costa(e) of a laminar structure. |
|
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. |
