tapeworm-shaped |
= taeniate |
solid shape |
|
Slender, elongate, basically cylindric or compressed-cylindric with shallow, narrow, more or less regular constrictions along its length, the whole apparently segmented and straight or variously curved. |
ligule 3 |
|
STRUCTURE |
|
A relatively small, attenuate, membranous, laminar enation from the adaxial surface of a leaf near its base; in Selaginella, Isoetes. |
capitate 2 |
= headed |
solid shape |
|
Abruptly enlarged distally to a relatively short, terminal portion that is basically round in transverse section. |
flexed |
= bent |
solid shape |
|
Having an abrupt bend at some point along its length. See also declinate (inclinate), geniculate (kneed), inflexed, reflexed. |
obtrulliform |
= obtrullate |
plane shape |
|
Inversely trulliform (trowel-shaped, trullate). |
stomatal apparatus |
= stomate, stoma (broad sense) |
STRUCTURE |
|
A localized functional epidermal unit consisting of a microscopic pore and two encircling specialized cells, the guard cells, which, through changes of turgor pressure in response to environmental conditions, regulate the size of the pore and thus the rates of transpiration and gas exchange through it; the whole surrounded or not by associated, cytologically distinctive epidermal cells, the subsidiary or accessory cells, which, when present, are regularly oriented in relation to it. |
punctiform |
= dot-like |
plane shape |
|
Very small and generally circular in outline. |
areola 1 pl. areolae |
= areole |
STRUCTURE |
|
Any distinctive surficial discontinuity of generally circular outline, whether concave, flush, or convex; when protuberant, sometimes bearing trichomes or spines, as in some Cactaceae. This term is used only when such entities are deemed structurally distinctive enough to merit description in their own rights, rather than as aspects of the surface. |
mentum pl. menta |
= column foot |
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. |
vascular |
|
insertion |
|
Upon or otherwise directly associated with the vasculature. |
glabrous |
= bald, psilate |
pubescence |
|
Lacking trichomes. |
parchment-like |
= pergamentaceous |
texture |
|
Very thin, pliable, and fairly tough; like parchment. See also chartaceous (papery, papyraceous), membranaceous (membranous). |
aculeate |
= spinose, spiny |
margin |
|
Having slender, stiff, sharp projections oriented in the general plane of the structure. |
beak 2 |
= rostrum |
STRUCTURE |
|
The inner, horn-like segment of a coronal lobe; esp. in Asclepiadaceae. |
surficial |
= superficial |
insertion |
|
Directly upon the surface of the structure in point. |
rhombate |
= rhombic |
plane shape |
|
Broadest at the middle and more or less regularly attenuate to either end, the sides angled at the middle and more or less straight from there to either end. |
corneous |
= horny |
texture |
|
Hard, dense, fine-grained or compactly fibrous, and tough; resembling the substance of animal horn. |
trigonous |
= three-angled, triquetrous; > deltoid, obdeltoid |
solid shape |
|
Elongate with three sides that meet at acute or obtuse angles. |
standard |
= banner, vexillum |
STRUCTURE |
|
The relatively large, erect adaxial (upper) petal in a papilionaceous corolla. |
pitcher-blade |
= ascidium, pitcher |
STRUCTURE |
|
A pitcher-shaped (ascidiform) leaf blade, sometimes lidded (operculate), usually carnivorous; esp. in Nepenthaceae, Sarraceniaceae. |
leaflet |
> pinna, pinnule |
STRUCTURE |
|
One of the one or more distinct, leaf-like, first- or higher-order divisions of a compound leaf blade; stalked (petiolulate) or sessile; borne upon a rachis or rachilla. |
callose |
= callous |
texture |
|
Hard-leathery; callose tissue usually is also thicker than comparable adjacent tissue. |
torsive |
= contortuplicate |
aestivation |
|
Plicate and contorted. |
fimbriate |
= fringed |
margin |
|
Regularly divided into slender, closely adjacent, more or less flexible segments, or having protrusions that give the appearance of such division. See also fimbrillate (fine-fringed). |
scarious |
|
texture |
|
Very thin, dry, and not green. |
