FEATURE |
|
Any structurally distinct compartment within an anther, ovary, fruit, sporangium or other organ; not necessarily having any evolutionary integrity. |

Having one or more areas that differ in color from the rest of the surface. See also eyespotted. |

Having the number of cells indicated by the prefix; as in bicellular, multicellular, oligocellular. |
|
…dentate 2 |
= …-toothed |
margin |
|
Having the number of orders of dentes (teeth) indicated by the prefix, one upon another; as in twice-dentate. See also …crenate (…-scalloped), …serrate (…-sawtoothed). |
|
radical |
|
insertion |
|
Upon, arising from, or otherwise directly associated with the root. |
|

|
Unusually or unexpectedly large. |
|
flange |

|
course |
|
Regularly wavy in one plane, curved alternately and more or less regularly to either side. |
|
granulate |
= granular, granulose |
texture |
|
Composed of grain-like particles; loose, dry, and coarsely particulate. |
|
lanceoloid |
= lancehead-shaped, lanciform |
solid shape |
|
Considerably longer than broad, compressed or not, broadest near the base and somewhat concavely attenuate to the apex, the attenuation in all median longitudinal planes or else largely confined to one, depending upon the extent of compression, if any. See also oblanceoloid (oblanciform). |
|
twice-… |
= bi…, double-… |
prefix |
|
Indicating presence of two hierarchical orders of the type of entity or pattern denoted by the term's stem; as in twice-crenate, twice-palmate. See also two-… (bi…, di…). |
|
annulus 2 pl. annuli |
|
STRUCTURE |
|
A row of protruding specialized sporangial wall cells that extends upward from the base of the sporangium and over its apex, thus forming an incomplete circumferential ring; esp. in Polypodiophyta. The inner and radial walls of the annular cells are markedly thickened and the structure functions as a spore-releasing and -disseminating mechanism as a result of differential stresses developed within the mature sporangial wall upon desiccation. |
|
beak 1 |
= rostrum |
STRUCTURE |
|
A relatively long, tapering, more or less rigid and pointed enation or termination. |
|
mottled |

|
aestivation |
|
Having the petals of the keel (carina) enclosing the others. |
|
oval |
= elliptic(al) |
plane shape |
|
Elongate, widest at the middle, and symmetrically convex-attenuate to rounded ends. See also oblong. |
