|
megaphyll |
= leaf, macrophyll (not recommended); > frond, needle |
STRUCTURE |
|
A principal, vegetative shoot organ borne laterally from a stem node; its vascular tissues, if any, continuous with those of the stem; undergoing no significant secondary growth; usually more or less bilaterally symmetrical; comprising a distal, usually laminar blade and/or a proximal stalk (petiole) or sheath; usually a primary site of photosynthesis. |
|
cucullate 1 |
= hooded |
architecture |
|
Bearing, incorporating, or surmounted by a hood-shaped structure. |
|
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. |
|
cauline |
|
insertion |
|
Upon, arising from, or otherwise directly associated with the stem. |
|
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. |
|
nodal |
> interpetiolar |
position |
|
Upon or associated with the nodes. |
|
disc 1 var. disk |
|
STRUCTURE |
|
Any distinct, annular to discoid structure produced from or borne upon a floral receptacle between or basal to any of the sets of floral organs; usually fleshy, often nectariferous. |
|
small-scalloped |
= crenulate |
margin |
|
Finely scalloped (crenate). See also sawtoothed (serrate), small-sawtoothed (serrulate), small-toothed (denticulate), toothed (dentate). |
|
pinnatisect |
< pinnate, pinnatifid |
plane shape |
|
Pinnately divided with the sinuses extending to the central axis. |
|
columella 1 pl. columellae, columellas |
= carpophore; < stalk |
STRUCTURE |
|
Any pedestal-like prolongation of a floral receptacle extending beyond the distalmost level of perianth insertion and bearing the gynoecium. |
|
fibrous root |
< diffuse root |
STRUCTURE |
|
A diffuse root that includes a significant component of woody or sclerotic strands and is consequently tough and often wiry. |
|
scallop |
= crena |
FEATURE |
|
A rounded, marginal convexity or concavity in a series of such that alternate regularly and are oriented more or less perpendicular to the generalized perimeter of a laminar structure. See also sawtooth, sawtoothlet, scalloplet (crenule), tooth (dens), toothlet. |
|
basal cell |
|
STRUCTURE |
|
Any of the ring of cells forming the lowermost (proximal) portion of an antheridial wall. |
|
staminal |
|
position |
|
Upon or otherwise directly associated with the stamens. |
|
capitulescence |
|
architecture |
|
Mode or progressive pattern of bearing capitula (heads); most appropriately described using adjectival terms; esp. in Asteraceae (Compositae). |
|
subsidiary cell |
|
STRUCTURE |
|
One of the cytologically distinctive epidermal cells that are sometimes present in a stomate and that surround and are regularly oriented in relation to the guard cells. |
|
prophyllar |
|
insertion |
|
Upon or otherwise directly associated with the prophylls (bracteoles, bractlets). |
|
elaiosome |
|
STRUCTURE |
|
A fleshy outgrowth from the seed coat (testa) that contains a high proportion of oil, usually attracting ants for dispersal. |
|
main stem |
= primary stem; > bole, trunk |
STRUCTURE |
|
The one, or any of the more than one, first-order stem(s), or first-order portion(s) of the collective stem, of a shoot. |
|
…crenate |
= …-scalloped |
margin |
|
Having the number of orders of crenae (scallops) indicated by the prefix, one upon another; as in bicrenate, twice-crenate. See also …dentate (…-toothed), …serrate (…-sawtoothed). |
