dolabrate |
= axehead-shaped |
solid shape |
|
Like an axehead oriented cutting edge downward. This term is not semantically distinct from dolabriform, but botanically they have had somewhat different applications. |
lepis pl. lepides |
= squama; < scale, trichome |
STRUCTURE |
|
A relatively thick, planate trichome. See also squamella. |
basicaulous |
|
insertion |
|
At or very near the stem base. |
oblique 1 |
|
base |
|
Asymmetric about its longitudinal axis. |
hilum 1 pl. hila |
|
FEATURE |
|
The scar left on a seed at the point of its abscission from the funiculus. |
crustaceous |
= crusty |
texture |
|
Thin, dry, hard, and brittle. |
pubescent 2 (strict sense) |
= downy |
pubescence |
|
Of or bearing relatively short, slender, soft, more or less erect, capillate trichomes. See also puberulent. This is one of the most ambiguous terms in the botanical lexicon; it should not be used unless its intended meaning is explicit. |
episepalous |
|
insertion |
|
Upon the sepals, or partially adnate thereto and apparently arising therefrom. |
megagametophyte |
> embryo sac |
PLANT |
|
A gametophyte whose fertile organs (gametangia) are all archegonia. |
flanged |
|
solid shape |
|
Having a relatively broad circumferential rim or ridge that protrudes laterally. |
flask-shaped |
= ampulliform, lageniform |
solid shape |
|
Generally circular in cross-section, broadest at or below the middle, approximately globose below that and constricted above to a relatively narrow neck; like a flask. |
seed |
|
STRUCTURE |
|
A mature or ripened ovule containing an embryonic sporophyte and a nutritive tissue (endosperm or perisperm) with stored food that sustains the initial growth of the embryo upon germination, except when such food reserve is stored instead in the cotyledon(s) of the embryo itself, these enclosed by one or two integuments (the testa), the whole serving as a propagule. A fertile seed (one containing a viable embryo) normally results from sexual fertilization of an egg by a sperm; however, fertile seeds are sometimes produced asexually by apomictic processes (e.g., parthenogenesis). |
gelatinous |
|
texture |
|
Jelly-like; soft, moist, continuously cohesive, texturally homogeneous, somewhat resilient, and easily cut. |
papillate |
= papillose |
relief |
|
Having small, conoidal protrusions overall; appearing pimply. |
insertion |
|
CHARACTER |
|
Mode or locus of attachment of a structure to some dissimilar bearing structure. The lexicons relating to insertion and position overlap to a great degree, since these two morphological concepts are often inseparable in practice. Also overlaps conceptually with arrangement, habit, orientation, and shape. |
retuse |
|
apex |
|
Round overall with an obtuse terminal sinus. |
…valleculate |
= …colpate, …fossulate, …furrowed, …grooved, …sulcate |
architecture |
|
Having the number of valleculae indicated by the prefix; esp. fruits of Apiaceae (Umbelliferae); as in tetravalleculate, 8-valleculate. |
awned |
= aristate, bristled |
apex |
|
Bearing one or more awns (aristae, bristles, setae). |
nodal |
> interpetiolar |
position |
|
Upon or associated with the nodes. |
small-scalloped |
= crenulate |
margin |
|
Finely scalloped (crenate). See also sawtoothed (serrate), small-sawtoothed (serrulate), small-toothed (denticulate), toothed (dentate). |
…colpate |
= …fossulate, …furrowed, …grooved, …sulcate, …valleculate |
architecture |
|
Having the number of colpi indicated by the prefix; esp. pollen grains; as in monocolpate, polycolpate, 3-colpate. |
chalaza pl. chalazae, chalazas |
|
STRUCTURE |
|
The basal (proximal) portion of an ovule, adjacent to its junction with the funiculus. |
pinnatisect |
< pinnate, pinnatifid |
plane shape |
|
Pinnately divided with the sinuses extending to the central axis. |
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. |
endophytic |
|
habit |
|
Growing within some portion of another, unrelated, living plant. |
