shaggy |
= villose, villous |
pubescence |
|
Bearing sparse, long, slender, soft, capillate trichomes that are not intertwined. See also villosulous. |
|
suprabracteal |
|

|
Upon the axes, each directly above (distal to) and very near a point of bract insertion. |
|

architecture |
|
Occurring in only one form within the taxon in point. |
|
trowel-shaped |
= trullate, trulliform |
plane shape |
|
Broadest below the middle, more or less straightly attenuate to either end, the sides angled at the level of greatest width; like the blade of a mason's trowel. See also obtrullate, obtrulliform. |
|
knob-shaped |
= gongylodate, gongyloid, knot-shaped, nodiform |
solid shape |
|
Approximately globose, the surface convoluted or not, like a knob or knot; usually applied only to structures or components that are relatively small. |
|
viscin |
= elastoviscin |
SUBSTANCE |
|
A sticky, elastic material, especially that forming the threads that sometimes connect pollen grains. |
|
ampulliform |
= flask-shaped, 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. |
|
axillary |
|
position |
|
Within the axil; nodal and at or very close to the vertex of the distal angle between a lateral structure, especially a leaf, and the axis that bears it. |
|
mesocarp |
|
STRUCTURE |
|
The middle tissue layer of the pericarp of a fruit. |
|
ochrea |
|
STRUCTURE |
|
See ocrea. |
|
perigynium 1 pl. perigynia |
|
STRUCTURE |
|
Two whorls of bracts, scales or setae immediately subtending the ovary, sometimes cupulate (cup-shaped) or ampulliform (flask-shaped, lageniform) and investing the fruit (achene); in Cyperaceae. |
|
crozier |
= fiddlehead |
STRUCTURE |
|
A circinate leaf (frond) prior to full expansion, while still wholly or distally coiled; esp. in Polypodiophyta. |
|
dodeca… |
= twelve-… |
prefix |
|
Indicating presence of or constitution by twelve entities of the type denoted by the term's stem; as in dodecandrous, dodecalocular, dodecastylous. |
|
rhombic |
= rhombate |
plane shape |
|
Broadest at the middle and more or less regularly attenuate to either end, the sides angled at the middle and more or less straight from there to either end. |
|
extravaginal |
|
position |
|
Distal to or outside the leaf sheath. |
|
semiobterete |
= half-obterete |
solid shape |
|
Inversely semiterete; obterete but flattened on one side. |
|
funicle |
= funiculus; < stalk |
STRUCTURE |
|
A stalk that attaches an ovule to a placenta of the ovary wall. |
|
spore |
|
STRUCTURE |
|
A simple, usually unicellular, sometimes oligocellular propagule derived by meiotic division of a diploid (2n chromosomes) sporocyte within a sporangium, thus of haploid (n chromosomes) genetic constitution. A spore constitutes the first ontogenetic stage of a gametophytic generation and gives rise to a usually multicellular gametophyte upon germination. Though technically present in seed-bearing plants, by itself it is descriptively significant only in those taxa that do not produce seeds. |
|
subterminal |
= subapical |
insertion |
|
Lateral and just below the apex. |
|
hemispheric(al) |
|
solid shape |
|
Half-spheric(al); broadest at the base and uniformly rounded to the apex, circular in any transverse section, and half-circular in any median longitudinal section. |
|
torn |
= cut, incised, lacerate; > laciniate, slashed |
plane shape |
|
Having straight to irregular lines of separation extending inward from the margin. See also cleft (dissected, divided, lobate, lobed, parted, partite, segmented). |
|
velum pl. vela |
|
STRUCTURE |
|
A membranous adaxial flap or fold of vegetative tissue wholly or partly covering the sporangial cavity of a sporophyll; in Isoëtaceae. |
|
broom-shaped |
= muscariform, penicillate |
solid shape |
|
Having a proximal axis that bears a distal cluster of elongate slender branches or appendages, these variously ascending to erect; like a broom. |
|
obcordate |
|
plane shape |
|
Inversely cordate (heart-shaped). |
|
pear-shaped |
= pyriform |
solid shape |
|
Basically circular in transverse section, broadest toward one end, attenuate toward and much narrower at the other, both ends rounded; slenderly turbinate or obturbinate; like a pear. |
