supramedial |
|
position |
|
Just above the middle of the structure in point. |
calcarate |
= spurred |
base |
|
Having a relatively slender protrusion resembling a spur. |
epigeal |
= epigeous |
location |
|
Upon or very near the surface of the ground; esp. of cotyledons following seed germination. |
rhizome |
= rootstock |
STRUCTURE |
|
An underground, usually horizontal stem, often superficially resembling a root but easily distinguished by the presence of nodes, from which it branches exogenously to produce the aboveground portion(s) of the shoot. |
cuboid |
|
solid shape |
|
Generally but not strictly cubic; more or less equilaterally six-sided, each side basically square. |
non-stomate-bearing |
= astomatiferous |
architecture |
|
Lacking stomates in the epidermis. |
helmet-shaped |
= galeate, galeiform |
solid shape |
|
Convex overall with a more or less smoothly curved apex, relatively thin-walled and essentially hollow with the interior open to one side below the distal portion; resembling a helmet. See also hood-shaped (cucullate, cuculliform), which overlaps conceptually. |
staminodial |
|
position |
|
Upon or otherwise directly associated with the staminodes. |
pit |
= fovea, scrobis |
FEATURE |
|
A small, rounded depression. |
axillary |
|
insertion |
|
Within the axil; nodal and at or very close to the vertex of the distal angle between a lateral structure, especially a leaf, and the axis that bears it. |
leaf-opposed |
|
position |
|
Nodal and directly opposite the leaf. |
top-shaped |
= turbinate |
solid shape |
|
Broadly obovoid-obconic; like a spinning top. See also pear-shaped (pyriform), obturbinate. |
filiform |
= thread-like |
solid shape |
|
Elongate and very slender, basically round in transverse section and of more or less uniform diameter, variously curved over its length or not. See also capillary (capillate, hair-like). |
palea 2 pl. paleae, paleas |
= pale, palet |
STRUCTURE |
|
The distal bract of the (usually) two that immediately subtend the flower in a grass (Poaceae) spikelet; the other is the lemma. |
induplicate |
|
aestivation |
|
Basically valvate but with each member involute, the lateral abaxial surfaces of adjacent members contiguous. |
subulate 2 |
= awl-shaped |
solid shape |
|
Slender, essentially terete, and straight, gradually attenuate from a relatively narrow base to a very narrow, blunt to angular apex. |
bristle 1 |
= arista, awn, seta |
STRUCTURE |
|
A slender, more or less straight and stiff, fine-pointed, terminal or subterminal appendage or prolongation, sometimes a continuation of the bearing structure's central primary vein, as on a glume, lemma, or palea in Poaceae (Gramineae). |
elliptic(al) 2 |
= oval |
plane shape |
|
Elongate, widest at the middle, and symmetrically convex-attenuate to rounded ends. See also oblong. |
recurved |
= arching |
orientation |
|
Curving outward (abaxially), downward, or backward. |
colpus pl. colpi |
= fossula, furrow, groove, sulcus, vallecula |
FEATURE |
|
An elongate depression that is relatively shallow and narrow. |
many-… |
= multi…, pluri…, poly… |
prefix |
|
Indicating presence of or constitution by a relatively large number of entities of the type denoted by the term's stem; as in many-angled, many-pistilled, many-seeded. See also few-… (oligo…). |
unguis pl. ungues |
= claw |
STRUCTURE |
|
The abruptly much narrower proximal portion, when present, of a laminar structure, esp. a petal; of variable shape itself, but usually attenuate toward the base. |
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. |
capitulescence |
|
architecture |
|
Mode or progressive pattern of bearing capitula (heads); most appropriately described using adjectival terms; esp. in Asteraceae (Compositae). |
lamella pl. lamellae |
|
STRUCTURE |
|
A thin layer of tissue that forms a plate within tissue of lesser density or between areas of empty space. |
