relief |
|
Having prominulous, more or less regularly interconnected lines. |
|
beaklet 1 |
= rostellum |
STRUCTURE |
|
A small beak or rostrum. |
|
vallecular |
|
insertion |
|
In or otherwise directly associated with the valleculae; esp. in fruits of Apiaceae (Umbelliferae). |
|
small-dotted |
= puncticulate |
coloration |
|
Finely dotted (punctate). |
|
central |
= medial, median |
position |
|
At, upon, or closely ranged about the structural or symmetrical midpoint or axis. |
|
laevigate 1 |
|
relief |
|
Very smooth. |
|
navicular |
= boat-shaped, cymbiform |
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. |
|
one-sided 1 |
= unilateral |
architecture |
|
Having only one side, as compared with presumably equivalent, bilaterally symmetric structures. |
|
furcate |
= forked; > bifurcate |
apex |
|
Having two or more terminal, antrorse branches or divisions arising from a common point or level, like the prongs of a fork. |
|
scale 1 |
< bract |
STRUCTURE |
|
A basically dry, more or less appressed, diminutive bract. The choice of term as between the more general bract and the more restricted scale is sometimes problematic and, when so, often is dictated by custom according to the structure and taxon involved. |
|
stamen |
|
STRUCTURE |
|
A seed-plant organ that produces and releases pollen; usually comprising a stalk (filament) that bears a locular structure (anther) containing sporogenous tissue; however, the filament may be lacking and the anther sessile, or the stamen may be undifferentiated, the whole then consisting of microsporangia embedded in or borne upon the surface of a more or less planate body of sterile tissue; one of the constituent organs of a bisexual or a staminate flower; may be distinct or else connate with one or more others and/or may be free or else adnate with one or more other floral structures. |
|
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°. |
|
commissure |
|
FEATURE |
|
Precisely, the joint or common boundary between the facing surfaces of two coherent or mutually appressed structures such as mericarps or stigmas, but traditionally (though imprecisely) applied to such a facing surface itself. |
|
corneous |
= horny |
texture |
|
Hard, dense, fine-grained or compactly fibrous, and tough; resembling the substance of animal horn. |
|
prop root |
|
STRUCTURE |
|
A relatively stout adventitious root arising from the lower portion of a main stem and extending outward and downward toward the substrate, within which it ultimately becomes anchored, thus buttressing the aboveground portion of the plant. |
|
bag-shaped |
= pouch-shaped, saccate, sack-shaped |
solid shape |
|
Irregularly obovoid with an exterior aspect intermediate between inflated and flaccid; like a closed pouch or bag. |
|
umbraculiform |
= umbrella-shaped |
solid shape |
|
Having a slender, elongate proximal axis and a very broad, meniscoid distal portion, the latter oriented with its convex face distal; like an umbrella. |
|
shiny |
= glossy, laevigate, lustrous, polished, shining |
reflectance |
|
Uniformly reflecting a high proportion of incident light at all angles. |
|
carinate |
= keeled |
solid shape |
|
Having an elongate median longitudinal ridge that is basically triangular in transverse section, resembling the keel of a boat; esp. a leaf blade or sheath, glume, lemma, palea, sepal or petal. |
|
isthmus |
|
STRUCTURE |
|
A narrower portion connecting two wider or broader portions of an inclusive structure. |
|
perigynium 1 pl. perigynia |
|
STRUCTURE |
|
Two whorls of bracts, scales or setae immediately subtending the ovary, sometimes cupulate (cup-shaped) or ampulliform (flask-shaped, lageniform) and investing the fruit (achene); in Cyperaceae. |
|
receptacle 2 |
= torus |
STRUCTURE |
|
The short, expanded, compound axial structure surmounting a peduncle and basal to two or more flowers, or to the florets of a capitulum (head) in Asteraceae (Compositae), where it may bear paleae (receptacular bracts), scales, bristles, trichomes, or subulate enations, and may be smooth or variously pitted (alveolate, foveolate). |
|
epipetalous |
|
insertion |
|
Upon the petals, or partially adnate thereto and apparently arising therefrom. |
|
spore case |
= sporangium |
STRUCTURE |
|
A spore-producing organ; basically capsular, often supported by a slender stalk (sporangiophore), often lidded (operculate). In Bryophyta and Polypodiophyta, a distinct portion of the sporangial wall effects regular dehiscence at maturity. Spore cases or their equivalents are also present, but of little or no descriptive significance, in seed plants. |
|
abaxial |
= dorsal (not recommended) |
position |
|
On or pertaining to the side or portion of a lateral structure that faces (or would face) away from the bearing axis when (or if) the axis of the lateral structure is (or were) oriented in the same general direction as the bearing axis. |
