filament |
|
STRUCTURE |
|
The stalk, when present, of a stamen, clearly differentiated from and bearing at its summit an anther. |
bundle scar |
|
FEATURE |
|
A smaller scar within the bounds of a leaf scar at the point where a vascular bundle traversed the abscission layer between stem and leaf. |
perfect |
|
architecture |
flower |
Having functional pistil(s) and functional stamen(s) both present, thus bisexual (hermaphroditic). |
foliose 2 |
|
architecture |
thallus |
Having leaf-like lobes; in Hepaticae. |
coalescent |
|
fusion |
equivalent and/or dissimilar structures |
Partially and irregularly coherent and/or adherent. |
viviparous |
|
reproduction |
|
Producing sexually or asexually generated offspring that begin growth and development while borne upon the parent plant. |
gibbous |
|
solid shape |
|
Bulging unilaterally near the base. |
circumcaulous |
|
position |
|
Upon and surrounding the stem. |
prickle |
|
STRUCTURE |
|
Any unvascularized spine-like enation originating in the epidermis, cortex, or mesophyll of any shoot part. See also spine, thorn. |
seedling |
|
PLANT |
|
A plant in the first stages of its growth following emergence from the seed. |
isodiametric |
|
architecture |
|
Of approximately constant breadth in all median planes. |
cotyloid |
|
architecture |
flower |
Having general adnation among the different sets of floral structures, thus having the ovary inferior and/or having a floral tube. |
stilt-rooted |
|
architecture |
plant |
Bearing and partly supported by stilt roots. |
cormose |
|
architecture |
plant |
Growing from corms. |
staminal |
|
insertion |
|
Upon or otherwise directly associated with the stamens. |
arrangement |
|
CHARACTER |
|
Disposition of equivalent structures with respect to one another (positions/insertions and/or orientations, regarded collectively) within some explicit or implicit standard context. Overlaps conceptually with habit, insertion, orientation, position, and shape. |
cyme |
|
nominative |
inflorescence |
Determinate and constituting a compound dichasium or monochasium, the flowers maturing from the center outward (i.e., the distal or inner flowers maturing first); often more or less flat-topped. See also cymule, dichasium, helicoid cyme, monochasium, rhipidium, scorpioid cyme. |
apotropous |
|
orientation |
ovule |
Anatropous but the whole recurved such that the raphe (adnate portion of the funiculus) faces the ovary wall (placenta) and the ovule is parallel to it, the micropyle facing the free basal portion of the funiculus. |
strobiloid |
|
architecture |
flower |
Characterized by a general lack of adnation among the different sets of basic floral structures, any significant degree of fusion limited to connation within sets, thus with ovary(ies) superior and lacking a floral tube. |
synangium pl. synangia |
|
STRUCTURE |
|
A compound sporangium; an aggregation of coherent sporangia, the whole multilocular. |
multiciliate |
|
architecture |
|
Having several to many cilia. |
synanthous |
|
maturation |
non-floral structure |
Maturing at the same time as the flowers. See also coetaneous. |
ocrea pl. ocreae var. ochrea |
|
STRUCTURE |
|
A tubular sheath that encircles a stem at a node, subtending a petiole; thought to have arisen evolutionarily by lateral fusion of two stipules; in Polygonaceae. |
oblanceolate |
|
plane shape |
|
Inversely lanceolate (lancehead-shaped). |
thyrse |
|
nominative |
inflorescence |
An elongate, indeterminate main axis bearing numerous lateral branches, each the principal axis of a cymose subdivision. |
