twig |
|
STRUCTURE |

|
architecture |
plant |

dehiscence |
|
Forming one or more apertures in the exterior wall, usually apically or sub-apically, through which the contents pass to the outside. |
fruity |
|
odor |
|
Sweetly to pungently fragrant and reminiscent of fruit. |
rachilla 2 var. rhachilla |
|
STRUCTURE |
|
A second-order axis in an inflorescence, especially the axis bearing the florets in a spikelet; esp. in Cyperaceae, Poaceae (Gramineae). |
solitary 2 |
|
habit |
plants |
Growing singly; not aggregated. |
gynobasic |
|
insertion |
style |
Apparently arising from the ovary base. |
pulvinate 1 |
|
architecture |
inflorescence axis, petiole |
Having a pulvinus. |
glomerule |
|
nominative |
inflorescence |
A compact cluster of capitula (heads), sometimes subtended by an involucre; thus, a compound capitulum (head); esp. in Asteraceae (Compositae). |
retrorse |
|
orientation |
|
Directed generally backward, toward the proximal end of the context of reference, parallel or at an acute angle to the bearing structure. |
heterogamous |
|
reproduction |
plant, inflorescence |
Having flowers that differ distinctly in size, shape and/or constitution. |
receptacular |
|
position |
|
Upon, arising from, or otherwise directly associated with the receptacle. |
second glume |
|
STRUCTURE |
|
The upper (distal) member of a pair of small bracts inserted at the base of a grass (Poaceae) spikelet. |
actinodromous |
|
venation |
|
Having three or more primary veins that diverge radially from a point at or above the base of the blade and run toward the margin, reaching it or not. |
chaff 1 |
|
STRUCTURE |
|
Collectively, the paleae (pales, palets) sometimes borne on the receptacle of a capitulum (head) in Asteraceae (Compositae). |
inframedial |
|
position |
|
Slightly below the middle of the structure in point. |
sheathing 1 |
|
architecture |
foliaceous structure |
Differentiated into distinct proximal and distal portions, the former terete or involute and closely enclosing the bearing axis above the point of insertion. |
casing |
|
STRUCTURE |
|
The portion (if any) of a floral tube that is adnate to the gynoecium. See also collar, neck. |
antheridium pl. antheridia |
|
STRUCTURE |
|
A male gametangium; a multicellular fertile organ of a mature gametophyte within which male gametes (antherozoids, spermatozoids) are produced and from which they are discharged, in some taxa forcibly, through a pore. Technically present but highly reduced and of no descriptive significance in Magnoliophyta and part of Pinophyta. |
septal |
|
position |
|
Upon or otherwise directly associated with the septum or septa. |
longitudinal 2 |
|
orientation |
|
Parallel to the long axis of the context of reference. |
androgynous |
|
reproduction |
taxon |
Monoecious, each inflorescence having a distal sector with only staminate flowers and a proximal sector with only pistillate ones. |
