cone |
= strobilus; > female cone, macrostrobilus (not recommended), male cone, megastrobilus, microstrobilus |
STRUCTURE |
|
A compound or complex reproductive structure consisting of a central axis bearing congested imbricate sporophylls and sometimes also sterile bracts. |
|
chamber (not recommended) |
= cell (not recommended), locule |
FEATURE |
|
Any structurally distinct compartment within an anther, ovary, fruit or other organ; not necessarily having any evolutionary integrity. |
|
granuliferous |
= powdery, pulverulent |
coating |
|
Covered with a more or less even deposit of fine, dry particles. See also lentiginous (dusty, lentiginose), which is not clearly distinct in its application. |
|
spine |
= thorn |
STRUCTURE |
|
Any sharp, stiff, simple or branched, woody appendage having vascular tissues confluent with those of the bearing structure. "Spine" is often preferred when the appendage is homologous with a leaf or stipule, and "thorn" when it is homologous with a branch. See also prickle. |
|
acinaciform |
= scimitar-shaped |
solid shape |
|
Thin and moderately arcuate with two opposite, plane, broad faces, the degree of curvature increasing distally, thinnest at the convex edge, thicker toward the concave; like a scimitar blade. |
|
dolabriform |
= axe-shaped |
solid shape |
|
Elongate, basally terete, becoming strongly compressed toward an abruptly and unilaterally broader apex; like an axe (handle plus head). This term is not semantically distinct from dolabrate, but botanically they have had somewhat different applications. |
|
plicate 1 |
|
aestivation |
|
Valvate with each member strongly infolded longitudinally. |
|
tailed 2 |
= caudate |
base |
|
With one or more relatively slender, retrorse basal enations or appendages. |
|
rostrum 1 pl. rostra |
= beak |
STRUCTURE |
|
A relatively long, tapering, more or less rigid and pointed enation or termination. |
|
flesh |
|
STRUCTURE |
|
Tissue that is fairly firm and dense, juicy or at least moist, and easily cut. |
|
crusty |
= crustaceous |
texture |
|
Thin, dry, hard, and brittle. |
|
beaked |
= rostrate |
apex |
|
Terminating in a relatively long, tapering, more or less rigid point. See also small-beaked (rostellate). |
|
beaklet 1 |
= rostellum |
STRUCTURE |
|
A small beak or rostrum. |
|
stoma 1 (broad sense) pl. stomata |
= stomatal apparatus, stomate |
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. |
|
puncticulate |
= small-dotted |
coloration |
|
Finely punctate (dotted). |
|
membranous |
= membranaceous |
texture |
|
Extremely thin, pliable, and fairly tough; like animal membrane. See also chartaceous (papery, papyraceous), pergamentaceous (parchment-like). |
|
…segmented |
? …cleft, …fid, …lobate, …lobed, …parted, …partite |
solid shape |
|
Having the number of segments indicated by the prefix; as in ten-segmented. |
|
glabrate |
= near-bald |
pubescence |
|
Nearly glabrous, with only a very sparse covering of trichomes. |
|
paraphysis pl. paraphyses |
|
STRUCTURE |
|
An elongate, multicellular, sterile structure borne between sporangia within a sorus; in Polypodiophyta. |
|
interpetiolar |
< nodal |
position |
|
Upon the stem between the bases of opposite leaves. |
|
supramedial |
|
position |
|
Just above the middle of the structure in point. |
|
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. |
|
caudex pl. caudices |
|
STRUCTURE |
|
The short, persistent, thickened, more or less erect, main stem of a perennial plant that otherwise has annual stems. |
|
non-stomate-bearing |
= astomatiferous |
architecture |
|
Lacking stomates in the epidermis. |
