|
symbiotic |
|
nutrition |
plant |
Partially dependent for essential nourishment upon other living organisms that derive some reciprocal benefit from the relationship. |
|
cotyliform |
|
solid shape |
perianth, calyx, corolla |
Having a short, relatively broad, cupulate tube and a well differentiated, erect limb. See also cyathiform, urceolate (urn-shaped). |

nominative |
inflorescence |
An elongate, determinate or usually indeterminate axis bearing sessile flowers inserted singly along it, unbranched or sometimes bearing lateral branches of the same nature. |
|
weak |
|
texture |
|
Very pliable and unresilient. |
|
erect |
|
orientation |
|
Perpendicular to the horizon or to the general plane of a bearing structure. |
|
appressed |
|
orientation |
lateral structure |
Angled at or near the base and closely flattened against the surface of the bearing structure, thus more or less parallel to it. |
|
gynaecium |
|
STRUCTURE |
|
See gynoecium. |
|
ridged |
|
solid shape |
|
Having one or more ridges; esp. fruits of Apiaceae (Umbelliferae). |
|
zygomorphic |
|
architecture |
perianth, calyx, corolla |
Bilaterally symmetric; divisible into two essentially equal portions along only one median logitudinal plane. |
|

|
FEATURE |
|
A central longitudinal cavity within the seed; esp. in Arecaceae (Palmae). |
|
rugulose |
|
relief |
|
Slightly or finely rugose (corrugate, wrinkled). |
|
throat 1 |
|
STRUCTURE |
|
The far distal portion of a perianth, calyx, or corolla tube, or of a leaf sheath, surrounding the orifice of the tube or sheath, sometimes constricted relative to the diameter of the main body of the tube or sheath; except in disc florets of Asteraceae (Compositae). |
|
cymulose |
|
architecture |
inflorescence |
Comprising one or more cymules. |
|
circinate 1 |

|
The upper (distal) member of a pair of small bracts inserted at the base of a grass (Poaceae) spikelet. |
