insertion |
|
At, upon, or closely ranged about the structural or symmetrical midpoint or axis. |

A relatively coarse, rounded protrusion or convexity. See also papilla. |

Asymmetric about its longitudinal axis. |

Having a distal, concave, relatively thin-walled, basically hemispherical portion surmounting a much narrower, transversely round, pedestal-like base. |
|
prickle |

STRUCTURE |
|
Any unvascularized spine-like enation originating in the epidermis, cortex, or mesophyll of any shoot part. See also spine, thorn. |
|
resinous 1 |
|
coating |
|
Of liquid or hardened resin. |
|
eusporangiate |
|
reproduction |
|
Having relatively large sporangia each of which develops from a group of initial cells that, by periclinal divisions, give rise to an outer layer of primary cells and an inner layer of sporogenous cells; in Psilotophyta, Lycopodiophyta, Equisetophyta, and some Polypodiophyta. |
|
…fossulate |
= …colpate, …furrowed, …grooved, …sulcate, …valleculate |
architecture |
|
Having the number of fossulae indicated by the prefix; as in unifossulate, multifossulate, 5-fossulate. |
|
spindle-shaped |
= fusiform |
solid shape |
|
Elongate, transversely round, broadest at the middle and regularly attenuate to either end. |
|
suberous |
= corky |
texture |
|
Firm, relatively light, discontinuous but strongly cohesive, and resilient. |
|
three-… |
= tri… |
prefix |
|
Indicating presence of or constitution by three entities of the type denoted by the term's stem; as in three-cleft, three-flowered, three-ranked. See also thrice… (tri…, triple…). |
|
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. |
|
lyrate |
= lyre-shaped |
plane shape |
|
Basically obovate but with several proximal concavities on each side, these sinuses opposite one another in pairs and decreasing in size toward the base; like the frontal outline of a lyre. |
|
bracteate |
= bracted |
architecture |
|
Bearing or subtended by one or more bracts. |
|
nodal |
> interpetiolar |
insertion |
|
Upon or associated with the nodes. |
|
chaff 1 |
|
STRUCTURE |
|
Collectively, the paleae (pales, palets) sometimes borne on the receptacle of a capitulum (head) in Asteraceae (Compositae). |
|
pappus pl. pappi |
|
STRUCTURE |
|
A set of one or more awns (aristae, bristles, setae) or scales at the summit of an inferior ovary just beneath or outside the free portion of the corolla; persisting in the fruit (cypsela) and often aiding wind or animal dispersal; in Asteraceae (Compositae). Considered by some to be an evolutionarily modified upper calyx portion, the lower portion having been incorporated into the floral tube casing adnate to the ovary wall; considered by others to be an outgrowth from the ovary wall. |
|
pluri… |
= many-…, multi…, 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 plurilocular, pluriseriate. See also oligo… (few-…). |
|
rank |
|
FEATURE |
|
A sequence of lateral structures arising from the same axis at successive points along its length and diverging from it in the same direction. |
|
epichilium |
|
STRUCTURE |
|
The distal portion of a labellum (lip) that has distinct proximal, distal, and sometimes also central parts; in Orchidaceae. See also hypochilium, mesochilium. |
|
scale 1 |
< bract |
STRUCTURE |
|
A basically dry, more or less appressed, diminutive bract. The choice of term as between the more general bract and the more restricted scale is sometimes problematic and, when so, often is dictated by custom according to the structure and taxon involved. |
