flask-shaped |
= ampulliform, lageniform |
solid shape |
|
Generally circular in cross-section, broadest at or below the middle, approximately globose below that and constricted above to a relatively narrow neck; like a flask. |
acrid 1 |
= pungent |
apex |
|
Terminating abruptly in a rigid, relatively short, sharp point composed of both vascular and laminar tissues. |
xylary |
|
position |
|
Within or otherwise directly associated with the wood. |
cuculliform |
= cucullate, hood-shaped |
solid shape |
|
Convex or compressed-convex overall with a distal peak or ridge, relatively thin-walled and essentially hollow with the interior open to one side below the distal portion; resembling a hood or cowl. See also galeiform (galeate, helmet-shaped), which overlaps conceptually. |
oily 1 |
= greasy, oleaginous, unctuous |
coating |
|
Of a grease- or oil-like film. |
woolly |
> lanate |
pubescence |
|
Of or bearing relatively long, moderately stout, intertwined, somewhat matted, capillate trichomes. |
divergent |
|
arrangement |
|
Directed at individually different angles from a common point or relatively limited zone of origin, thus farther apart distally than proximally. |
fusion |
|
CHARACTER |
|
Physical connection of equivalent or dissimilar structural entities (as recognized on evolutionary, morphological, anatomical, ontogenetic, and/or topological grounds). Terms that denote the interconnection of equivalent structures are predicated on a single collective subject and suffice in themselves to describe the condition; e.g., "sepals connate." However, those that denote the connection of dissimilar structures require explicit notation of each type of structure involved, in either a compound-subject construction or else a single-subject/object-of-preposition construction; e.g., "stamens and corolla adnate" or "stamens adnate to corolla." Qualifying detail is sometimes appropriate; e.g., "filaments connate basally," "filaments adnate to the petals over their lower halves." |
receptacular |
|
insertion |
|
Upon, arising from, or otherwise directly associated with the receptacle. |
subpetiolar |
|
insertion |
|
Just below the point of petiole insertion. |
subulate 1 |
= awl-shaped |
plane shape |
|
Narrowly triangular or truncate-triangular and broadest at the base; like the outline of the lateral face of an awl. |
tetrad |
|
STRUCTURE |
|
A group of four pollen grains originating from a single pollen mother cell. |
macrospore (not recommended) |
= megaspore |
STRUCTURE |
|
A female spore; a spore of the larger of two types produced by the sporophytes of a heterosporous taxon; produced in a megasporangium; giving rise upon germination to a megagametophyte. |
snail-shell-shaped |
= cochleate |
solid shape |
|
Relatively broad and short, basically round in transverse section, resembling a rapidly tapering spire overall, the exterior helically convoluted. |
ciliate |
|
margin |
|
Having fine, hair-like trichomes (cilia) oriented in the general plane of the structure. |
sporophyll |
= spore leaf; > fertile frond |
STRUCTURE |
|
A leaf or homologous structure that bears sporangia. See also megasporophyll (macrosporophyll, not recommended), microsporophyll. |
gynandrium pl. gynandria |
= column, gynostemium |
STRUCTURE |
|
A central floral structure consisting of the partly to wholly fused (connate and adnate) androecium and gynoecium; esp. in Orchidaceae. |
fibrous root |
< diffuse root |
STRUCTURE |
|
A diffuse root that includes a significant component of woody or sclerotic strands and is consequently tough and often wiry. |
primocane |
|
STRUCTURE |
|
A biennial or perennial stem before it has begun flowering, when the latter does not occur until at least its second season of growth; esp. in Rubus (Rosaceae). |
oblanceoloid |
= oblanciform |
solid shape |
|
Inversely lanceoloid (lancehead-shaped, lanciform). |
wall (fruit, ovary, pollen, spore) |
|
STRUCTURE |
|
The exterior layer of tissue(s) enclosing anatomically distinct interior tissues and sometimes fluid and/or one or more cavities. |
archegonium pl. archegonia |
|
STRUCTURE |
|
A female gametangium; a multicellular fertile organ of a mature gametophyte within which female gametes (eggs, ova) are produced and fertilized; having a broad, bulbous base and a narrower distal neck. Technically present but highly reduced and of no descriptive significance in Magnoliophyta. |
hypanthium 2 (strict sense) pl. hypanthia |
= floral cup (strict sense) |
STRUCTURE |
|
A marginal protrusion from or enlargement of the receptacle (torus) of a flower, encircling and wholly, partly or not at all adnate to the gynoecium, bearing the perianth and androecium. |
epigeous |
= epigeal |
location |
|
Upon or very near the surface of the ground; esp. of cotyledons following seed germination. |
four-… |
= quadr(i)…, tetra… |
prefix |
|
Indicating presence of or constitution by four entities of the type denoted by the term's stem; as in four-angled, four-petaled, four-ranked. |
