adenopetalous 1 |
|
architecture |
flower, perianth, corolla |
Having petals produced from glandular structures. |
|
mamilla pl. mamillae |
|
STRUCTURE |
|
A nipple- or teat-shaped protrusion. |
|
pulvinus pl. pulvini |
|
STRUCTURE |
|
A short, cushion-like swelling at the junction of stem and leaf or of inflorescence axis and branch. |
|
comose |
|
pubescence |
|
Bearing a prominent single tuft of relatively long and slender, flexible, capillate trichomes (coma). |
|
infrabracteal |
|
position |
|
Upon the axis directly below a bract insertion. |
|
partial |
|
extent |
|
Not reaching fully from the ovary wall or pericarp to the center of the ovary or fruit and/or from the apex to the base of its interior, thus not completely separating adjacent locules, which are recognized and delimited by extrapolating from the incomplete septal boundary(ies), the ovary or fruit nonetheless effectively unilocular. |
|
unisexual |
|
reproduction |
|
Having functional reproductive structures of only one sex. See also imperfect, pistillate, staminate. |
|
membrane |
|
STRUCTURE |
|
A relatively thin layer of tissue that covers or separates other, different tissue(s) and/or empty space(s). |
|
radical |
|
insertion |
|
Upon, arising from, or otherwise directly associated with the root. |
|
continuous 3 |
|
architecture |
rachilla, rachis |
Not disarticulating at maturity. |
|
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. |
|
anisosepalous |
|
architecture |
flower, perianth, calyx |
Having sepals unequal in size and/or shape. |
|
surface |
|
FEATURE |
|
The exterior or bounding area or layer of any structure, regarded as being infinitely thin; usually described as to relief, reflectance, and/or vesture. |
|
corymbose |
|
architecture |
inflorescence |
Comprising one or more corymbs. |
|
piliferous |
|
apex |
|
Having a distinct, fine, weak, hair-like portion or protrusion. |
|
apolar |
|
architecture |
pollen grain, spore |
Lacking morphologically evident polarity. |
|
neck (archegonial) |
|
STRUCTURE |
|
The distal narrowed portion of an archegonium above its bulbous base. |
|
plane shape |
|
CHARACTER |
|
Overall two-dimensional form or aspect(s) thereof. Overlaps conceptually with architecture, arrangement, habit, insertion, orientation, and position. |
|
spore |
|
STRUCTURE |
|
A simple, usually unicellular, sometimes oligocellular propagule derived by meiotic division of a diploid (2n chromosomes) sporocyte within a sporangium, thus of haploid (n chromosomes) genetic constitution. A spore constitutes the first ontogenetic stage of a gametophytic generation and gives rise to a usually multicellular gametophyte upon germination. Though technically present in seed-bearing plants, by itself it is descriptively significant only in those taxa that do not produce seeds. |
