STRUCTURE |
|
An elongate cell with a helical, hygroscopic thickening in its wall, contained within a sporangium, expanding and contracting with changes in humidity and aiding dispersal of the spores; esp. in Hepaticae. |

An elongate aperture in the proximal face of a spore at or near its pole, coterminous with a tetrad scar; in Psilotophyta, Lycopodiophyta, Equisetophyta, Polypodiophyta. Depending upon tetrad configuration and resultant scar pattern, a laesura may be either unbranched or branched, the branches when present (usually 3) radiating from the pole and of approximately equal lengths. |
|
dropper |
= tuberoid |
STRUCTURE |
|
An axial outgrowth that descends from a bulb and eventually forms a new bulb; esp. in Orchidaceae. |

|
caudicle |

STRUCTURE |
|
An attenuate end portion by which a pollinium adheres to a pollinating insect, either directly or by means of a terminal viscidium, the latter, when present, sometimes attached by an intervening stipe; esp. in Asclepiadaceae, Orchidaceae. |

STRUCTURE |
|
An ascidiform (pitcher-shaped) leaf blade, sometimes operculate (lidded), usually carnivorous; esp. in Nepenthaceae, Sarraceniaceae. |
|

FEATURE |
|
An area that differs in color from the rest of a structure's surface. See also eyespot. |
|
macula pl. maculae |
= blotch, spot |
FEATURE |
|
An area that differs in color from the rest of a structure's surface, usually due to differing coloration. See also eyespot. |

SUBSTANCE |
|
An aqueous exudate of high sugar content. |
|
aril 1 (broad sense) |
> arillode, arillus |
STRUCTURE |
|
An appendicular structure that wholly or partly envelops a seed and is produced from or a modification of the funicle, raphe, outer integument, or (in some Pinophyta) a subtending involucre; usually fleshy or pulpy, sometimes spongy or tufted-capillate, often brightly colored. |
|
aril 2 (strict sense) |
= arillus |
STRUCTURE |
|
An appendicular structure that wholly or partly envelops a seed and is an outgrowth from the funicle or raphe, and thus is ontogenetically derived from the placenta; usually fleshy or pulpy, sometimes spongy or tufted-capillate, often brightly colored. |
|
arillus pl. arilli |
= aril (strict sense); < aril (broad sense) |
STRUCTURE |
|
An appendicular structure that wholly or partly envelops a seed and is an outgrowth from the funicle or raphe, and thus is ontogenetically derived from the placenta; usually fleshy or pulpy, sometimes spongy or tufted-capillate, often brightly colored. |
|
gynostegium pl. gynostegia |
< corona |
STRUCTURE |
|
An androecial corona, typically consisting of distinct hood- and/or horn-shaped enations that rise above the anthers; esp. in Asclepiadaceae. |
|
gland |
> nectary |
STRUCTURE |
|
An anatomically distinct multicellular structure that produces and exudes a particular substance, or resembles those that do. |
|
woody clump |
|
nominative |
plant |
An aggregate of woody main stems that arise from belowground organs derived from a single progenitor; the members of a clump are individually tree- or shrub-like and sometimes become physically separate over time. See also bush, frutex, shrub, subshrub, suffrutex, tree, undershrub. |
|
follicetum pl. folliceta |
|
STRUCTURE |
|

|
climbing root |
< aerial root |
STRUCTURE |
|

|
ligule 2 |
|
STRUCTURE |
|
An adaxial, distal enation from a leaf sheath, especially in most grasses (Poaceae) and sedges (Cyperaceae); usually unitary and membranous, sometimes instead consisting of a row of ciliate processes. See also hastula. |
