|
proliferous |
|
reproduction |
plant, structure |
Bearing plantlets, as from the leaf margin in some Kalanchoë (Crassulaceae). |
|
hemispheric(al) |
|
solid shape |
|
Half-spheric(al); broadest at the base and uniformly rounded to the apex, circular in any transverse section, and half-circular in any median longitudinal section. |
|
raceme |
|
nominative |
inflorescence |
An elongate, unbranched main axis bearing pedicellate flowers inserted singly along it. |
|
ridged |
|
solid shape |
|
Having one or more ridges; esp. fruits of Apiaceae (Umbelliferae). |
|
scorpioid cyme |
|
nominative |
inflorescence |
A cyme in which each axial segment branches to only one side, the successive segments branching alternately to either side, the whole appearing to have a continuous, elongate, straight to zig-zag main axis. See also cincinnus, helicoid cyme (bostryx). |
|
inferior 1 |
|
insertion |
indusium |
Inserted at the base of the sorus. |
|
semicraspedodromous |
|
venation |
|
Having a single median primary vein that branches to either side along the length of the lamina, each secondary vein running thence toward and bifurcate near the margin, one branch terminating at the margin, the other upwardly arcuate and merging with the superadjacent secondary vein, thus forming one of a series of marginal loops. |
|
alternate 1 |
|
arrangement |
|
Inserted singly along the axis, each at a different level and each diverging on a different radius than the ones next above and below. |
|
sorus pl. sori |
|
STRUCTURE |
|
A cluster of sporangia borne upon a fertile frond, usually on its abaxial surface; often covered during maturation by a protective membrane, the indusium, that is an outgrowth from the epidermis; in Polypodiophyta. |
|
ligulate 2 |
|
architecture |
floret |
Bisexual with a zygomorphic corolla; in Asteraceae (Compositae). |
|
apostemonous |
|
architecture |
flower, androecium |
Having two or more distinct stamens; having the stamens unfused. |
|
calyculate 1 |
|
architecture |
capitulum (head) |
With the involucre subtended by a calyculus; in Asteraceae (Compositae). |
|
leaf-opposed |
|
insertion |
|
Nodal and directly opposite the leaf. |
|
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. |
|
mamilla pl. mamillae |
|
STRUCTURE |
|
A nipple- or teat-shaped protrusion. |
|
cauline |
|
position |
|
Upon, arising from, or otherwise directly associated with the stem. |
|
angled |
|
solid shape |
|
Having sides that meet at acute or obtuse angles. |
|
spinulose |
|
margin |
|
Finely spinose. |
|
carinal |
|
aestivation |
|
Having the petals of the keel (carina) enclosing the others. |
|
monochasiate |
|
architecture |
inflorescence |
Comprising one or more simple or compound monochasia. See also cincinnate, cymose, cymulose, dichasiate, helicoid-cymose, scorpioid-cymose. |
|
oblique 1 |
|
apex |
|
Asymmetric about its longitudinal axis. |
|
membrane |
|
STRUCTURE |
|
A relatively thin layer of tissue that covers or separates other, different tissue(s) and/or empty space(s). |
|
subvalvate |
|
dehiscence |
|
Incompletely or partly valvate. |
