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. |

|
Directed downward or backward. |
ten-… |
= deca… |
prefix |
|
Indicating presence of or constitution by ten entities of the type denoted by the term's stem; as in ten-carpeled, ten-stamened, ten-winged. |
leaf 2 pl. leaves |
= microphyll |
STRUCTURE |
|
A small, lateral, leaf-like enation that, evolutionarily, is not a true leaf, i.e., whose vasculature, if any, consists of only a single median strand not ontogenetically integral with the vasculature of the bearing stem and not associated with leaf gaps in the stele of the stem; in Psilotophyta, Lycopodiophyta, Equisetophyta. |
umbonate |
= bossed |
solid shape |
|
Having an umbo. |
bi… 2 |
= double-…, twice-… |
prefix |
|
Indicating presence of two hierarchical orders of the type of entity or pattern denoted by the term's stem; as in bicrenate, bipinnate. See also entries for particular terms beginning with this prefix whose meanings, at least in some applications, are more specific than usually indicated by such combination. |
cartilaginous |
= cartilage-like |
texture |
|
Firm, dense, tough, somewhat pliable, and resilient, like human cartilage. |
palate |
|
STRUCTURE |
|
The lower, prominent labium (lip) of a personate (gaping, ringent) corolla. |
cone scale |
< macrosporophyll (not recommended), megasporophyll, microsporophyll; > ovuliferous scale |
STRUCTURE |
|
One of the membranous, fleshy, or woody sporophylls of a cone (strobilus); esp. in Pinophyta. |
pitcher |
= ascidium, pitcher blade |
STRUCTURE |
|
A pitcher-shaped (ascidiform) leaf blade, sometimes lidded (operculate), usually carnivorous; esp. in Nepenthaceae, Sarraceniaceae. |

STRUCTURE |
|
The hard seed of a drupelet; esp. in Rosaceae. |

prefix |
|
Indicating presence of or constitution by eleven entities of the type denoted by the term's stem; as in eleven-carpelled, eleven-leafleted, eleven-stamened. |
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). |
globular |
= globose, orbicular, rotund, spheric(al), spheroid(al) |
solid shape |
|
Uniformly convex, circular in any median section and in outline when viewed from any angle; like a globe or sphere. |
star-shaped 2 |
= stellate |
solid shape |
|
Having a distal aspect like the stylized shape of a star; stipitate or sessile with elongate branches or appendages radiating widely in three dimensions from a common point at the apex of the proximal axis or, when sessile, upon the bearing surface. |
horny |
= corneous |
texture |
