…angled |
= …gonous |

|
floricane |

STRUCTURE |
|
A biennial or perennial stem after it has begun flowering, when that does not occur until at least its second season of growth; applied especially to the stems of brambles (Rubus spp.). |
|
rhizoid |
|
STRUCTURE |
|
Any structure that is similar to a root in appearance and function but that is not a true root ontogenetically and anatomically, especially one produced from a gametophyte thallus. |
|
divided |
? cleft, dissected, lobate, lobed, parted, partite, segmented |
plane shape |
|
Having two or more component sectors or peripheral protrusions that are delimited by concavities in the surface or margin and that are not proximally distinct from the remainder of the whole. The meanings of this term and its approximate synonyms sometimes have been supposed to differ according to the depth of the delimiting concavities relative to the midline or midpoint of the overall structure, and/or to the shape or proportions of the protusions or sectors; however, there has been little consistency in the applications of the various terms according to such distinctions, which are ones only of degree and are necessarily arbitrary in any case. In general usage, these terms differ only indistinctly and connotatively: cleft, lobed (or lobate), parted (or partite) and segmented tend to connote fewer protrusions or sectors; lobate usually connotes as well a generally rounded shape; dissected tends to connote more numerous sectors that are elongate and angular. See also cut (incised, lacerate, torn), laciniate (slashed). |

Lacking vessels, the tracheary elements limited to tracheids and, sometimes, fiber-tracheids. |
|
scabrellate |
= scabrellous, scabridulous |
relief |
|
Minutely scabrous (rough, scabrate, scabrid, scabridous). See also spiculate, which is not clearly distinct in its application. |
|
staminode |
= staminodium |
STRUCTURE |
|
Any sterile structure deemed to represent a modified stamen, homology being inferred on the basis of structural similarity, ontogeny, and/or position; sometimes petaloid, sometimes nectariferous, sometimes connate with others or adnate to other floral structures. |
|
pistillode |
= pistillodium |
STRUCTURE |
|
Any sterile structure deemed to represent a modified pistil, homology being inferred on the basis of structural similarity, ontogeny, and/or position; sometimes nectariferous, sometimes connate with others or adnate to other floral structures. |
|
cruciate 2 |
= cross-shaped |
solid shape |
|
Having two elongate, basically straight portions intersecting at a point interior to the ends of each. |
|

Having the number of orders of teeth (dentes) indicated by the prefix, one upon another; as in twice-toothed. See also …-sawtoothed (…serrate), …-scalloped (…crenate). |
|
scape |
|
STRUCTURE |

A leafless, essentially naked, inflorescence-bearing stem (or peduncle) arising directly from a caudex or rhizome, its point of insertion slightly beneath, at, or slightly above the substrate surface. |
|
corm |
|
STRUCTURE |
|
A short, thickened, solid, usually subterranean, sometimes fleshy stem base containing stored carbohydrates and serving as a perennating organ. |
|
pale 2 |
= palea, palet |
STRUCTURE |
|
The upper or distal of the (usually) two distinctive bracts immediately subtending the flower in a grass (Poaceae) spikelet. |
|

STRUCTURE |
|
A slender, more or less straight and stiff, fine-pointed, terminal or subterminal appendage or prolongation, sometimes a continuation of the bearing structure's central primary vein, as on a glume, lemma, or palea in Poaceae (Gramineae). |
