striate 2 |

relief |
|
Covered with very narrow and shallow, relatively long, more or less straight and parallel depressions. |
|
tertiary vein |
|
STRUCTURE |
|
A strand belonging to the third order of vasculature in a leaf or other basically laminar structure, except when that is the ultimate order (consisting of veinlets); branching from a primary or secondary vein. See also costa, lateral vein, primary vein, rib, secondary vein, veinlet. |
|
lobed |
? cleft, dissected, divided, lobate, parted, partite, segmented |
plane shape |
|
Having one or more component sectors or peripheral protrusions that is/are delimited by concavities in the surface or margin and that is/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). |
|
bisexual |
= hermaphroditic |
reproduction |
|
Having functional reproductive structures of both sexes. See also perfect. |

solid shape |
|
Like the generalized form of a boat hull, the walls relatively thin to moderately thick, the interior essentially empty and open along one side. |
|
conspicuous |
> showy |
manifestation |
|
Prominently evident. |
|
deltate |
|
plane shape |
|
Equilaterally triangular, broadest at the base, and regularly attenuate to an angular apex. See also obdeltate. |
|
rachis 2 var. rhachis |
|
STRUCTURE |
|
A main or first-order axis of an inflorescence. |
|
flabellate |
= fan-shaped, flabelliform |
solid shape |
|
Strongly compressed, broadest near the apex and attenuate to a narrow base, plaited longitudinally, the alternating folds radiating from the base, the whole basically triangular in broad aspect; like a partially expanded folding fan. |
|
…gonal |
= …angular |
plane shape |
|
Having more or less straight sides of the number indicated by the prefix; as in pentagonal, trigonal. See also deltate, …gonous (…angled). |
|
sterile frond |
= trophophyll |
STRUCTURE |
|
A frond that does not bear sporangia; in Polypodiophyta. See also fertile frond. |
|
laminar 2 |
|
solid shape |
|
Relatively very thin with parallel opposite broad faces, the whole plane or variously curved. Structures to which this term, along with any other three-dimensional ones, is applicable are often also described as though only two-dimensional, using terms that are implicitly understood to refer only to the outline of the broad faces. |
|
…winged |
= …pterous |
architecture |
|
Having the number of wings (alae) indicated by the prefix; as in 3-winged, five-winged. |
|
basicaulous |
|
insertion |
|
At or very near the stem base. |
|
capitiform |
= capitate, head-shaped |
solid shape |
|
Basically globose and resembling a head in the context of occurrence. |
|
opposite 2 |
|
arrangement |
|
Having the members of each whorl inserted directly above and/or below those of the next adjacent whorl(s). See also antipetalous, antisepalous. |
|
column foot |
= mentum |
STRUCTURE |
|
A lateral, often nectariferous protrusion from the proximal portion of a column, opposite the labellum, projecting in front of the rest of the flower; in Orchidaceae. |
|
phyllodium pl. phyllodia |
= phyllode |
STRUCTURE |
|
A leaf deemed to consist entirely or almost entirely of tissues evolutionarily derived from the petiole, all or a distal portion of which has become laminar, the original blade reduced to the point of absence or vestigiality. |
|
cut |
= incised, lacerate, torn; > laciniate, slashed |
plane shape |
|
Having straight to irregular lines of separation extending inward from the margin. See also cleft (dissected, divided, lobate, lobed, parted, partite, segmented). |
|

= blistered, bullate, pustulate |
relief |
|
Having relatively coarse, irregularly disposed, rounded protrusions or convexities resembling blisters. See also papillate, papillose. |
|
dusty |

coating |
|
Covered with a more or less even deposit of minute, dry, macroscopically indistinguishable particles. See also powdery (pulverulent), which is not clearly distinct in its application. |
