|
arrangement |
bundle scars |
Forming a circle. |
|
ligule 2 |
|
STRUCTURE |
|
An adaxial, distal enation from a leaf sheath, especially in most grasses (Poaceae) and sedges (Cyperaceae); usually unitary and membranous, sometimes instead consisting of a row of ciliate processes. See also hastula. |
|
filament |
|
STRUCTURE |
|
The stalk, when present, of a stamen, clearly differentiated from and bearing at its summit an anther. |
|
heteropolar |
|
architecture |
pollen grain, spore |
Having morphologically evident polarity, the proximal and distal halves dissimilar. |
|
oil-secreting |
|
exudation |
|
Producing and exuding an oily substance, often aromatic; when oil-secreting glands are indicated in the nominative, often they are called simply oil glands. |
|
tuberous 1 |
|
architecture |
plant |
Bearing tubers. |
|
discal |
|
insertion |
|
Upon or otherwise directly associated with the floral disc. |
|
discal |
|
position |
|
Upon or otherwise directly associated with the floral disc. |
|
loose 2 |
|
texture |
|
Soft overall, discontinuously and only weakly cohesive. |
|
pseudomonadal |
|
arrangement |
pollen |
Apparently monadal but each grain actually comprising an unseparated original tetrad in which the contiguous walls between component grains have dissolved. |
|
coleorhiza |
|
STRUCTURE |
|
A sheath-like structure enclosing the radicle (embryonic root) in an embryo; esp. in Poaceae (Gramineae). |
|
inconspicuous |
|
manifestation |
|
Not prominently evident. |
|
septicidal |
|
dehiscence |
fruit |
Splitting longitudinally into or through the suture(s) in the outer wall and, if present, through the septum(-a) between locules, the latter thus opened indirectly to the outside. |
|
unbranched 2 |
|
architecture |
laminar veinlet |
Not branching within the areole. |
|
aggregate fruit |
|
nominative |
fruit |
Compound and derived from the two or more simple, superior ovaries of a single apocarpous flower; the ovaries connate, coherent, or contiguous in the fruit, the whole with or without accessory tissue. |
|
massula pl. massulae |
|
STRUCTURE |
|
A body of coherent pollen grains, dispersed as a unit; esp. in Asclepiadaceae, Orchidaceae. |
|
bud-scale scar |
|
FEATURE |
|
A scar on a stem due to abscission of a bud scale. The scar(s) encircle(s) the axis to which the bud was terminal, each single scar having an outline like that of a transverse section through the base of the bud scale that was inserted there. Sets of bud scale scars (one set per bud) usually delimit seasonal stem growth increments in temperate zone taxa. |
|
integument |
|
STRUCTURE |
|
A distinct layer of tissue that encloses and serves to protect the other tissues of an organ, especially a seed. |
|
androdioecious |
|
reproduction |
taxon |
Having some plants with only bisexual flowers and others only staminate ones. |
|
microspore |
|
STRUCTURE |
|
A male spore; a spore of the smaller of the two types produced by the sporophytes of a heterosporous taxon; produced in a microsporangium; giving rise upon germination to a microgametophyte. |
|
rank |
|
FEATURE |
|
A sequence of lateral structures arising from the same axis at successive points along its length and diverging from it in the same direction. |
|
superaxillary |
|
insertion |
|
Internodal but close to and directly above the axil(s). |
|
calyptrate |
|
architecture |
|
Having or constituting a calyptra. |
|
isostemonous |
|
architecture |
flower, androecium |
Having the stamens essentially alike in size and shape. |
