foliose 1 |
|
architecture |
stem |
Bearing many leaves. |
|
mamillate |
|
relief |
|
Bearing mamillae. |
|
infrafoliar |
|
insertion |
|
Upon the stem directly below a leaf insertion. |
|
subvalvate |
|
dehiscence |
|
Incompletely or partly valvate. |
|
amphimictic |
|
reproduction |
taxon, plant |
Reproducing sexually. |
|
radical |
|
position |
|
Upon, arising from, or otherwise directly associated with the root. |
|
caespitose |
|
habit |
|
See cespitose. |
|
involucrate 2 |
|
architecture |
capitulum (head) |
Having an involucre. |
|
perianth tube |
|
STRUCTURE |
|
A relatively narrow, fully connate portion of a syntepalous (gamotepalous) perianth proximal to a broader portion (limb) that comprises the distinct or connate distal portions of the tepals. |
|
sinus pl. sinus, sinuses |
|
FEATURE |
|
The space, indentation, or invagination (or, for some descriptive purposes, the outline thereof) between and delimiting any two consecutive or adjacent lobes or teeth of a structure. |
|
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. |
|
anisosepalous |
|
architecture |
flower, perianth, calyx |
Having sepals unequal in size and/or shape. |
|
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. |
|
extrafloral |
|
position |
|
Outside and proximal to the flower; esp. nectaries. |
|
thallus 1 pl. thalli |
|
STRUCTURE |
|
The vegetative portion of a shoot when not differentiated into stem and leaves; esp. in Lemnaceae. |
|
aromatic |
|
odor |
|
Having a distinct odor; usually restricted to pleasant odors. |
|
nut |
|
nominative |
fruit |
Relatively large, indehiscent, one-loculed, one-seeded and with a thick, hard, sometimes osseous pericarp; derived from a single, simple or compound ovary. See also acorn (glans). |
|
polyplicate |
|
architecture |
pollen grain |
Inaperturate with meridional folds, thus appearing longitudinally wrinkled. |
|
leptosporangiate |
|
reproduction |
|
Having relatively small sporangia each of which develops from a single initial cell that, by periclinal division, gives rise to an outer and an inner cell, the former then giving rise to the entire sporangium, including contents and sporangiophore, the latter contributing nothing to it; in some Polypodiophyta. |
|
herbaceous 2 |
|
texture |
|
Composed entirely of relatively soft, non-woody (unlignified) tissues derived from primary growth. |
