summer annual |
|
nominative |
plant |
Annual, germinating in spring or early summer, reproducing sexually with no prolonged vegetative stage beforehand, and dying by late summer or autumn. See also winter annual. |
extrorse |
|
dehiscence |
anther |
Opening outwardly, on the abaxial side. See also introrse, latrorse. |
column 2 |
|
STRUCTURE |
|
A fused androecium (connate stamens) closely surrounding but free from the gynoecium; esp. in Malvaceae. |
naked 1 |
|
architecture |
|
Lacking a covering that might have been expected. |
inflated |
|
solid shape |
|
Relatively thin-walled with an essentially empty interior largely enclosed by the walls, which are convex overall and appear taut, as though from internal pressure. See also swollen (turgid, tumid), which is not clearly distinct in its application. |
apiculate |
|
apex |
|
Terminating abruptly in a short, slender, angular tip that is not notably harder or stiffer than the main body of the structure. See also mucronate, mucronulate. |
cymulose |
|
architecture |
inflorescence |
Comprising one or more cymules. |
concolor(ous) |
|
coloration |
|
Uniform in hue and intensity of color; esp. leaves with identically colored adaxial and abaxial surfaces. |
fibrous |
|
texture |
|
Having tough, woody or sclerotic strands distributed through a softer matrix. |
tomentose |
|
pubescence |
|
Bearing dense, short, stiff, capillate trichomes. See also tomentulose. |
non-porous |
|
porosity |
|
Lacking vessels, the tracheary elements limited to tracheids and, sometimes, fiber-tracheids. |
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. |
elliptic(al) 1 |
|
arrangement |
bundle scars |
Forming an ellipse |
homosporous |
|
reproduction |
taxon |
Producing only one type of spore, each spore giving rise to a gametophyte that bears gametangia of both sexual types. |
irregular 2 |
|
course |
|
Deviating asymmetrically from a straight line. |
allagostemonous |
|
architecture |
flower, androecium |
Having the stamens inserted alternately upon petals and the receptacle. |
obvolute 1 |
|
arrangement |
cotyledons |
Having each cotyledon folded inward longitudinally, the two facing one another with their edges overlapping alternately (each enveloping one side or the other). |
syncolporate |
|
architecture |
pollen grain |
Syncolpate, each groove containing a pore. |
monadal |
|
arrangement |
pollen |
Shed singly, or essentially so, only loosely and irregularly, if at all, coherent, each original tetrad having separated fully. |
asymmetric(al) 1 |
|
architecture |
|
Not divisible into essentially equal halves along any line or plane. |
pseudobulb |
|
STRUCTURE |
|
An enlarged internode of an aboveground stem, storing water and photosynthate, resembling a bulb; esp. in Orchidaceae. |
asymmetric(al) 1 |
|
plane shape |
|
Not divisible into essentially equal halves along any line or plane. |
pseudolamina pl. pseudolaminae |
|
STRUCTURE |
|
The expanded part of a phyllode (phyllodium), resembling a blade but evolutionarily derived from the petiole. |
divaricate |
|
arrangement |
|
Strongly divergent. |
grumous |
|
solid shape |
|
Having an external aspect like a cluster of grains, basically convex overall. |
