inflorescence 2 |
|
STRUCTURE |
|
The basic architectural unit of the flower-producing portion of a plant; comprising one or more flowers, their associated supporting axes (peduncles, main axes, branches and pedicels), if any, and the appendages thereto (bracts, bractlets or bracteoles or prophylls, involucres, involucels, and glumes), if any; delimited by the insertion or gradation of a single peduncle, peduncle cluster, pedicel, pedicel cluster, or sessile flower, as the case may be, directly upon or into some proximal vegetative structure not of one of these types; depending upon the type(s) of flowers included, may be bisexual (all flowers bisexual), staminate (all flowers staminate), pistillate (all flowers pistillate), sterile (all flowers sterile), or mixed (two or more types of flowers present); most appropriately described using nominative terms. |
|
arillate |
|
architecture |
seed |
Having an aril. |
|
beard |
|
STRUCTURE |
|
A growth of relatively long, erect, flexible, capillary trichomes from one or more limited sectors of a structure's surface. |
|
sepal |
|
STRUCTURE |
|
One of the one or more constituent members of a calyx; usually green and leaf-like, but sometimes with color and/or texture otherwise, sometimes petaloid; may be distinct or else connate with one or more others and/or may be free or else adnate to one or more other floral structures. |
|
knee 2 |
|
STRUCTURE |
|
An emergent portion of an otherwise normally submerged secondary root of a wetland tree, resembling a bent human knee. |
|
spathe |
|
STRUCTURE |
|
A usually relatively large, sometimes showy, foliose bract subtending and sometimes partially enclosing an inflorescence, esp. a spadicate one; in Liliidae (monocotyledons). |
|
brochidodromous |
|
venation |
|
Having a single median primary vein that branches to either side along its length, the secondary veins incurving strongly near but short of the margin, interconnecting serially, and forming a succession of marginal loops. |
|
sinuate |
|
margin |
|
Having regular, curved, smoothly connected, alternating concavities and convexities. See also repand. |
|

elongate structure |
Hollow over a significant part of its length, the interior open at the end of the hollow portion. |
|

|
CHARACTER |
|
Degree or nature of evidence when present within the context in point. |
|
naked 2 |
|
architecture |
bud |
Lacking enclosing protective scales, the outermost embryonic components exposed and not differing significantly from those within. See also perulate. |
