|
hilum 2 pl. hila |

FEATURE |
|
The more or less central point within a starch grain of intracellular origin, about which the successive layers of starch were accreted more or less symmetrically. |
|
trichotomocolpate |
|
architecture |
pollen grain |
Having a triradiate surficial groove (colpus). |
|
hygroscopic |
|
architecture |
structure |
Increasing or decreasing in size according to the presence or absence of surrounding moisture, due to differential swelling or shrinking of component anatomical structures. |
|
discoid 2 |
|
architecture |
capitulum (head) |
Bearing florets that all have actinomorphic corollas and that are all bisexual, or all functionally staminate, or all functionally pistillate; in Asteraceae (Compositae). |
|
acrocaulous |
|
position |
|
At or very near the stem tip. |
|
pseudoterminal |
|
insertion |
|
Only apparently terminal; originally subapical but displaced toward the apex by differential growth during development. |
|
collateral |
|
position |
buds |
In pairs within or immediately straddling the leaf axils, the members of a pair lateral to one another. |
|
brachiate |
|
architecture |
axis |
Having alternate, divaricate branches. |
|
indehiscent |
|
dehiscence |
|
Not splitting or forming an aperture at maturity, the contents being released for dispersal only after decay, digestion, or erosion of the structure. |
|
pappose |
|
architecture |
flower, fruit |
Bearing a pappus; esp. in Asteraceae (Compositae). |
|
…seriate 1 |
|
architecture |
trichome |
Multicellular with the number of longitudinal columns of superposed cells indicated by the prefix; as in biseriate, multiseriate, uniseriate. |
|
quincunx |
|
aestivation |
|
Imbricate in one whorl of five members, two wholly exterior, two wholly interior, and one partially exterior and partially interior. |
|
internodal |
|
position |
|
Upon or otherwise directly associated with the internodes. |
|
valve |
|
STRUCTURE |
|
Any longitudinal segment of a fruit wall delimited by lines of dehiscence. |
|
elliptic(al) 1 |
|
arrangement |
bundle scars |
Forming an ellipse |
|
androgynous |
|
reproduction |
taxon |
Monoecious, each inflorescence having a distal sector with only staminate flowers and a proximal sector with only pistillate ones. |
|
raphides sing. raphis |
|
STRUCTURE |
|
Needle-like crystals of calcium oxalate contained within the cells of some plants; esp. in Araceae. |
|
superior 2 |
|
position |
ovary |
Not enclosed to any degree by a floral tube casing, the perianth and/or androecium thus arising beneath (proximal to) it. |
|
campylodromous |
|
venation |
|
Having several primary and/or strongly developed secondary veins that diverge from a point or small area near the base of the blade and run thence ultimately toward the apex, recurving proximally, arcuate and converging distally, reaching the apex or not. |
|
epidermis pl. epidermides, epidermises |
|
STRUCTURE |
|
The anatomically distinct, outermost, living tissue that encloses and protects the other tissues of a plant organ or part, usually overlaid by an exuded waxy cuticle; resulting from primary growth, disrupted and shed as a consequence of secondary growth if that occurs; consisting mainly of cells not further specialized, otherwise including various types of more specialized cells associated with trichomes and stomates. |
|
antipetalous |
|
insertion |
equivalent floral structures |
Each inserted directly above or below a petal. In place of this term, the phrase "opposite the petals" is often used, but that contradicts the sense of opposite as otherwise employed (arrangement of lateral structures along an axis) and should be avoided. |
