|
synandrous |
|
architecture |
flower, androecium |
Having the stamens connate. |
|
spinose 1 |
|
apex |
|
Terminating in a rigid, tapering, sharp continuation of the central primary vein. See also spinulose. |

gynomonoecious |
|
reproduction |
taxon |
Having all plants with both bisexual flowers and pistillate ones. |
|
terminal |
|
insertion |
|
Apical and with the same developmental axis as the whole, of which it is the distalmost portion or appendage. |
|
leaf-opposed |
|
position |
|
Nodal and directly opposite the leaf. |
|
asymmetric(al) 1 |
|
architecture |
|
Not divisible into essentially equal halves along any line or plane. |
|
oblique 1 |
|
apex |
|
Asymmetric about its longitudinal axis. |
|
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). |
|
present |
|
presence |
|
Occurring within the context in point. |
|
barb 2 |
|
STRUCTURE |
|
A trichome terminated by one or two small, relatively short, stiff, sharp, acutely reflexed appendages. |
|
hilum 2 pl. hila |
|
FEATURE |
|
The more or less central point within a starch grain of intracellular origin, about which the successive layers of starch were accreted more or less symmetrically. |
|
trichotomocolpate |
|
architecture |
pollen grain |
Having a triradiate surficial groove (colpus). |
|
hygroscopic |
|
architecture |
structure |
Increasing or decreasing in size according to the presence or absence of surrounding moisture, due to differential swelling or shrinking of component anatomical structures. |
|
discoid 2 |
|
architecture |
capitulum (head) |
Bearing florets that all have actinomorphic corollas and that are all bisexual, or all functionally staminate, or all functionally pistillate; in Asteraceae (Compositae). |
|
acrocaulous |
|
position |
|
At or very near the stem tip. |
|
pseudoterminal |
|
insertion |
|
Only apparently terminal; originally subapical but displaced toward the apex by differential growth during development. |
|
collateral |
|
position |
buds |
In pairs within or immediately straddling the leaf axils, the members of a pair lateral to one another. |
|
brachiate |
|
architecture |
axis |
Having alternate, divaricate branches. |
|
indehiscent |
|
dehiscence |
|
Not splitting or forming an aperture at maturity, the contents being released for dispersal only after decay, digestion, or erosion of the structure. |
|
pappose |
|
architecture |
flower, fruit |
Bearing a pappus; esp. in Asteraceae (Compositae). |
