…seriate 1 |
|
architecture |
trichome |
Multicellular with the number of longitudinal columns of superposed cells indicated by the prefix; as in biseriate, multiseriate, uniseriate. |
anchoring |
|
habit |
trichome |
Serving as a means of attachment to some external support. |
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. |
spikeleted |
|
architecture |
inflorescence |
Having the penultimate subdivisional order consisting of spikelets. |
anthela pl. anthelae |
|
nominative |
inflorescence |
A cyme with the main axis markedly shorter than the lateral axes, appearing generally paniculate when compound; esp. in Juncaceae. |
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. |
staminate |
|
architecture |
inflorescence, flower, floret |
Having functional stamens but no functional pistils, thus unisexual and male. |
appressed |
|
orientation |
lateral structure |
Angled at or near the base and closely flattened against the surface of the bearing structure, thus more or less parallel to it. |
cryptocotyloid |
|
germination |
seed |
Having the cotyledon(s) remaining inside the seed coat. |
cuboid |
|
solid shape |
|
Generally but not strictly cubic; more or less equilaterally six-sided, each side basically square. |
neuter |
|
architecture |
flower, floret |
Lacking both stamens and pistils. |
basicauliramous |
|
architecture |
plant |
Having the stem(s) branching at or near the base. See also basiramous. |
dimidiate |
|
solid shape |
|
Halved, figuratively; bilaterally asymmetric, nearly or wholly lacking one side as implicitly compared with some corresponding bilaterally symmetric structure, real or imagined. |
syncarpous |
|
architecture |
flower, gynoecium |
Having one or more compound pistils. |
axil |
|
FEATURE |
|
The space bounded by and near the vertex of the distal angle between a lateral structure, especially a leaf, and the axis that bears it. |
suprabasal |
|
insertion |
|
Just above the base of the structure in point. |
dyad |
|
STRUCTURE |
|
A pair of coherent pollen grains shed as a unit. |
birettaform |
|
solid shape |
|
Approximately square in cross section and shallowly convex at the top; like a biretta (Roman Catholic cleric's hat). |
