involucrate 1 |
|
architecture |
inflorescence |
Subtended by an involucre. |
|
perianth |
|
STRUCTURE |
|
Collectively, all the sterile, primary, lateral organs (tepals, or sepals and/or petals) of a flower; inserted upon the floral axis immediately beneath (proximal to) the reproductive organs (androecium and/or gynoecium) and surrounding them, often protectively; lacking in some taxa; the individual members typically laminar and more or less foliaceous; widely regarded as consisting of the evolutionarily modified leaves of a fertile shoot; the constituent members undifferentiated with respect to one another, or else differentiated into more or less distinct floral envelopes (calyx and corolla), one or the other of which is deemed lacking in some taxa due to evolutionary reduction following differentiation. |
|
sinuous |
|
course |
|
Regularly wavy in one plane, curved alternately and more or less regularly to either side. |
|
endophytic |
|
habit |
|
Growing within some portion of another, unrelated, living plant. |
|
anisophyllous |
|
architecture |
plant, axis |
Heterophyllous and bearing leaves of two or more distinct sizes or shapes on the same plants. |
|
reflectance |
|
CHARACTER |
|
Aspect as to proportion and pattern of incident light reflected from the surface. |
|
supramedial |
|
position |
|
Just above the middle of the structure in point. |
|
phyllopodium pl. phyllopodia |
|
STRUCTURE |
|
A stem-like axis composed of fused leaf bases; esp. in Arecaceae (Palmae), Musaceae. |
|
wall (fruit, ovary, pollen, spore) |
|
STRUCTURE |
|
The exterior layer of tissue(s) enclosing anatomically distinct interior tissues and sometimes fluid and/or one or more cavities. |
|
episepalous |
|
position |
|
Upon the sepals, or partially adnate thereto and apparently arising therefrom. |
|
cross-vein |
|
STRUCTURE |
|
A relatively short, secondary or higher-order vein that runs directly between two veins of the next lower order, intersecting them more or less perpendicularly. |
|
lanulose |
|
pubescence |
|
Finely lanate. |
|
extrafloral |
|
insertion |
|
Outside and proximal to the flower; esp. nectaries. |
|
aristate 2 |
|
apex |
pappus scale |
Terminating in one or more awn- or bristle-like appendages. |
|
nucellus pl. nucelli |
|
STRUCTURE |
|
The distinct, genetically diploid tissue layer immediately surrounding the embryo sac of an ovule; often considered equivalent to a megasporangium wall. |
|
texture |
|
CHARACTER |
|
Substantial properties. Overlaps conceptually with solid shape, as to thickness. |
|
fertile |
|
reproduction |
plant, reproductive structure |
Producing functional spores, gametes, pollen, ovules, seeds, or other propagules. |
|
herb |
|
nominative |
plant |
Annual, biennial, or perennial with no woody (lignified) tissue in any part of the shoot; when persisting over more than one growing season, the parts of the shoot dying back seasonally. |
|
obturbinate |
|
solid shape |
|
Inversely turbinate (top-shaped). See also pyriform (pear-shaped). |
|
basicauliramous |
|
architecture |
plant |
Having the stem(s) branching at or near the base. See also basiramous. |
|
homosporous |
|
reproduction |
taxon |
Producing only one type of spore, each spore giving rise to a gametophyte that bears gametangia of both sexual types. |
|
scorpioid-cymose |
|
architecture |
inflorescence |
Comprising one or more scorpioid cymes. See also cincinnate, helicoid-cymose. |
|
trulloid |
|
solid shape |
|
Elongate, basically square in transverse section, broadest below the middle, regularly attenuate to angular ends, all faces essentially plane. See also obtrulloid. |
