position |
|
Upon or arising from the roots. |

apiculum 2 pl. apicula |
|
STRUCTURE |
|
The apex of a connective, when prolonged above the union of the anthers. |
|
spongy |
|
texture |
|
Soft, light, discontinuous but cohesive, and somewhat resilient. |
|
woody clump |
|
nominative |
plant |
An aggregate of woody main stems that arise from belowground organs derived from a single progenitor; the members of a clump are individually tree- or shrub-like and sometimes become physically separate over time. See also bush, frutex, shrub, subshrub, suffrutex, tree, undershrub. |
|
tetradal |
|
arrangement |
pollen |
Shed in groups of four, each an intact tetrad with original configuration unchanged; geometric arrangement of the grains may be tetrahedral, tetragonal, or linear, depending upon mode of pollen mother cell division. |
|
cyathiform |
|
solid shape |
perianth, calyx, corolla, pappus |
Having a cupulate tube and an indistinct, erect limb. See also cotyliform, urceolate (urn-shaped). |
|
chasmogamous |
|
reproduction |
flower |
Having the perianth open at anthesis, allowing deposit of pollen from other flowers (physiological receptivity aside). |
|
polygamomonoecious |
|
reproduction |
taxon |
Basically monoecious but with some or all plants bearing some bisexual flowers. |
|
autotrophic |
|
nutrition |
plant |
Independent of other organisms for its nourishment, itself synthesizing all essential substances not directly available from the non-living environment. |
|
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. |
|
tortuous |
|
course |
|
Strongly irregular with sharp bends and/or curves. |
|
prominence |
|
CHARACTER |
|
Elevation or depression of a discrete feature relative to the surrounding surface. |
|
stigmatic |
|
habit |
trichome |
Borne on the surface of the stigma and serving to hold pollen deposited there, variously shaped, often glandular, sometimes contractile. |
|
base |
|
CHARACTER |
|
Configuration of the lowermost or proximal portion of a structure, its extent determined somewhat subjectively in relation to the shape of the structure as a whole. The concept of base varies from one descriptive context to another, since the base is not a clearly delimited, morphologically distinct entity. The terms for describing basal condition are not strictly coordinate logically — some are more inclusive than others, and some describe conditions involving what can be regarded as appendages — and precise characterization may require using more than one descriptor. The semantic antecedent of some descriptors is "base," whereas the antecedent of others is the structure as a whole (e.g., leaf ). |
|
opposite 2 |
|
arrangement |
|
Having the members of each whorl inserted directly above and/or below those of the next adjacent whorl(s). See also antipetalous, antisepalous. |
|
scorpioid cyme |
|
nominative |
inflorescence |
A cyme in which each axial segment branches to only one side, the successive segments branching alternately to either side, the whole appearing to have a continuous, elongate, straight to zig-zag main axis. See also cincinnus, helicoid cyme (bostryx). |
|
flanged |
|
solid shape |
|
Having a relatively broad circumferential rim or ridge that protrudes laterally. |
|
prophyllar |
|
insertion |
|
Upon or otherwise directly associated with the prophylls (bracteoles, bractlets). |
|
stipel |
|
STRUCTURE |
|
A stipular analogue subtending a leaflet. |
|
hysteranthous |
|
maturation |
non-floral structure, esp. leaf |
Maturing later than the flowers. |
|
semicraspedodromous |
|
venation |
|
Having a single median primary vein that branches to either side along the length of the lamina, each secondary vein running thence toward and bifurcate near the margin, one branch terminating at the margin, the other upwardly arcuate and merging with the superadjacent secondary vein, thus forming one of a series of marginal loops. |
|
divergent |
|
arrangement |
|
Directed at individually different angles from a common point or relatively limited zone of origin, thus farther apart distally than proximally. |
|
…adelphous |
|
architecture |
flower, androecium |
Having two or more distinct sets of stamens, the sets differing from one another in the arrangements, insertions, positions and/or morphologies of the included stamens, the number of sets indicated by the prefix, at least one set with two or more members; as in diadelphous, monadelphous, triadelphous. |
|
style |
|
STRUCTURE |
|
A narrow, usually elongate, ontogenetically distal portion of a simple or compound pistil, overtopping the ovary and bearing one or more stigmas; arising from the summit of the ovary, but sometimes apparently from its base at maturity to ontogenetic displacement from its primordial distal position. In a compound pistil the various simple (carpellary) components of the style(s) may not be connate over their entire lengths; the pistil is then regarded as having a branched style or styles. |
|
commissure |
|
FEATURE |
|
Precisely, the joint or common boundary between the facing surfaces of two coherent or mutually appressed structures such as mericarps or stigmas, but traditionally (though imprecisely) applied to such a facing surface itself. |
