|
deciduous 1 |
|
duration |
structure |
Separating and falling away from the bearing axis, organ or plant prior to senescence of the latter, usually by developing an anatomically distinct, transverse, basal zone of cells (abcission layer), where separation occurs. See also seasonally deciduous. |
|
anchoring |
|
habit |
trichome |
Serving as a means of attachment to some external support. |
|
stinging |
= urent |
habit |
trichome |
Setaceous or capillate and ejecting an irritating fluid when the apex is dislocated by external pressure, the ejection accomplished by release of existing internal fluid pressure or by contraction of the whole trichome. |

|
acute |
= sharp |
apex |
|
Sharply angular; regularly and more or less straightly attenuate to an angular tip, the sides intersecting at an angle of less than 90°. |
|
tetradal |
|
arrangement |
pollen |
Shed in groups of four, each an intact tetrad with original configuration unchanged; geometric arrangement of the grains may be tetrahedral, tetragonal, or linear, depending upon mode of pollen mother cell division. |
|
polyadal |
|
arrangement |
pollen |
Shed in groups of more than four, each group comprising grains from two or more original tetrads, the latter intact or not. |
|
monadal |
|
arrangement |
pollen |
Shed singly, or essentially so, only loosely and irregularly, if at all, coherent, each original tetrad having separated fully. |
|
coroniform |
= crown-shaped |
solid shape |
|
Shortly and broadly tubular overall, circumferentially continuous at the base, distally so or not; like a monarch's crown. |

|
odor |
|

|
cryptic |
|
coloration |
|
Similar to its natural background, from which it is not readily distinguished. |

|
taeniate |
= tapeworm-shaped |
solid shape |
|
Slender, elongate, basically cylindric or compressed-cylindric with shallow, narrow, more or less regular constrictions along its length, the whole apparently segmented and straight or variously curved. |

= subulate |
solid shape |
|
