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. |

solid shape |
|
Elongate, transversely round, broadest at the middle and regularly attenuate to either end. |

three-… |

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. |
|
bracted |
= bracteate |
architecture |
|
Bearing or subtended by one or more bracts. |
|
nodal |
> interpetiolar |
position |
|
Upon or associated with the nodes. |
|
chaff 2 |
|
STRUCTURE |
|
Collectively, the glumes, lemmata, and paleae of mature spikelets; in Poaceae (Gramineae). |
|
pappus scale |
|
STRUCTURE |
|
A pappus element that is more or less planate and relatively thin and broad; may terminate in one or more awn- or bristle-like appendages. |
|
corneous |
= horny |
texture |
|
Hard, dense, fine-grained or compactly fibrous, and tough; resembling the substance of animal horn. |
|
pneumatophore |
|
STRUCTURE |
|
A structurally and functionally specialized root serving as an aboveground aerating organ; found in some woody taxa of wet habitats, notably some mangroves. |
|
…ranked |
= …stichous |
arrangement |
|
Disposed along the axis in the number of distinct ranks indicated by the prefix; as in two-ranked. |
|
epicotyl |
= plumule |
STRUCTURE |
|
A distinguishable nascent shoot developed in the embryo in some taxa, consisting of a shoot axis with unexpanded internodes and one or more leaf primordia, being that portion of the embryo above the level of cotyledon insertion; the primordial shoot, when developed by the embryo within a seed; the first bud of a spermatophyte, when developed by an embryo within the seed. In other taxa the shoot is represented in the embryo only by a quiescent apical meristem at the summit of the embryonic axis. |
|
scale 2 |
> lepis, squama, squamella, squamule; < trichome |
STRUCTURE |
|
A planate trichome. |
