follicetum pl. folliceta |
|
STRUCTURE |
|
An aggregate of follicles produced from a single flower with multiple simple pistils. |
pith |
|
STRUCTURE |
|
The central ground tissue of a stem or, when present, of a root, consisting of thin-walled parenchyma cells; distinct and more or less soft and spongy relative to the other tissues of the axis; sometimes partly or wholly degenerating after secondary growth has begun. |
flexuose |
|
course |
|
See flexuous. |
pseudoaxillary |
|
insertion |
|
Only apparently axillary; originally extraaxillary but displaced to the axil by differential growth during development. |
gigantic |
|
size |
plant |
Strongly enlarged; unusually or unexpectedly very large throughout. |
prickly |
|
architecture |
|
Bearing prickles. |
radicle |
|
STRUCTURE |
|
The primary root, or its primordium, in an embryo; the portion of an embryo axis that develops into the root. |
anatropous |
|
orientation |
ovule |
Having the funiculus distally recurved and the (straight) ovule lying beside and parallel to the proximal portion of the funiculus, to which it may be adnate or adherent, the micropyle facing the ovary wall (placenta). |
aromatic |
|
odor |
|
Having a distinct odor; usually restricted to pleasant odors. |
rhizophore |
|
STRUCTURE |
|
A stem branch that bears no leaves and from which roots eventually arise; esp. in Selaginellaceae. |
apostemonous |
|
architecture |
flower, androecium |
Having two or more distinct stamens; having the stamens unfused. |
hirsute |
|
pubescence |
|
Bearing coarse, rough, elongate, more or less erect, capillate trichomes. See also hirtellous. |
samara |
|
nominative |
fruit |
Dry, indehiscent and having one or more integral alate portions that aid in aerial dispersal. |
caudex pl. caudices |
|
STRUCTURE |
|
The short, persistent, thickened, more or less erect, main stem of a perennial plant that otherwise has annual stems. |
sap |
|
SUBSTANCE |
|
Generally, the fluid content of a plant body; more precisely, the sugary fluid transported by the phloem. |
incurved |
|
orientation |
|
Curving adaxially. See also decurved. |
acropetal |
|
development |
|
Proceeding toward the apex, thus more advanced basally or proximally than apically or distally within a given frame of reference. |
…seriate 1 |
|
architecture |
trichome |
Multicellular with the number of longitudinal columns of superposed cells indicated by the prefix; as in biseriate, multiseriate, uniseriate. |
capsule |
|
nominative |
fruit |
Dry, longitudinally or poricidally dehiscent, and derived from a compound ovary with one or more locules; containing one or more seeds. See also pyxis. |
isopolar |
|
architecture |
pollen grain, spore |
Having evident polarity, the proximal and distal halves similar. |
laticiferous |
|
exudation |
|
Producing and exuding latex. |
sporophyte |
|
PLANT |
|
The main, ultimate, spore-bearing stage in the diploid (2n chromosomes) phase of a taxon's life cycle. Two morphologically and genetically distinct and alternate phases together constitute the complete life cycle in sexually reproducing taxa, the other phase (gametophytic) being haploid (n chromosomes). Any taxon whose life cycle is confined to one or the other phase is limited to asexual means of reproduction, since sexual reproduction with consequent genetic recombination is impossible without alternation between haploid and diploid states via meiosis and fertilization. The term sporophytic applies to any part of the diploid phase, including all unicellular to multicellular entities belonging to it, whereas sporophyte is reserved for the principal and directly spore-producing stage of that phase. |
colporate |
|
architecture |
pollen grain |
Having one or more elongate, relatively narrow and shallow depressions (colpi), each containing a pore. |
spikeleted |
|
architecture |
inflorescence |
Having the penultimate subdivisional order consisting of spikelets. |
craspedodromous, mixed- |
|
venation |
|
Having a midvein that branches to either side along the length of the lamina, the secondary veins running thence toward the margin, some becoming indistinct before reaching it, others terminating there. |
