oblate |
|
solid shape |
|
Symmetrically elongate and broader than long perpendicular to the developmental or polar axis. |
tiered |
|
arrangement |
|
In two or more rows that are arrayed one above another. |
cirrhous |
|
apex |
|
Having a narrow spiral tip that is a continuation of the central primary vein. |
liguliflorous |
|
architecture |
capitulum (head) |

presence |
|
CHARACTER |
|
Occurrence within the context in point. |
barb 1 |
|
STRUCTURE |
|
Any relatively short, stiff, sharp, acutely inserted or bent, antrorse or retrorse, terminal or lateral appendage. |
hilum 1 pl. hila |
|
FEATURE |
|
The scar left on a seed at the point of its abscission from the funiculus. |
dichasiate |
|
architecture |
inflorescence |
Comprising one or more simple or compound dichasia. See also cincinnate, cymose, cymulose, helicoid-cymose, monochasiate, scorpioid-cymose. |
pachycaulous |
|
architecture |
plant |
Having thick, more or less succulent stems. |
seed |
|
STRUCTURE |
|
A mature or ripened ovule containing an embryonic sporophyte and a nutritive tissue (endosperm or perisperm) with stored food that sustains the initial growth of the embryo upon germination, except when such food reserve is stored instead in the cotyledon(s) of the embryo itself, these enclosed by one or two integuments (the testa), the whole serving as a propagule. A fertile seed (one containing a viable embryo) normally results from sexual fertilization of an egg by a sperm; however, fertile seeds are sometimes produced asexually by apomictic processes (e.g., parthenogenesis). |
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. |
free-central |
|
placentation |
|
Upon the free axial column of a compound, unilocular ovary. |
subpetiolar |
|
position |
|
Just below the point of petiole insertion. |
internodal |
|
insertion |
|
Upon or otherwise directly associated with the internodes. |
peltate |
|
architecture |
foliaceous structure |
Petiolate with the petiole attached to the abaxial face of the blade at some point within the margin and otherwise free from the blade. |
valvate 4 |
|
dehiscence |
fruit |
With longitudinal segments of the wall (valves) separating partly or wholly from one another, spreading outward from the base or apex, and sometimes falling away. |
ellipsoid(al) |
|
solid shape |
|
Elliptic in any median longitudinal section; elongate, transversely circular, broadest at the middle, and symmetrically convex-attenuate to rounded ends. See also oblong. |
gamophyllous |
|
architecture |
plant, shoot axis, involucre |
Having pairs or whorls of leaves or bracts that are connate at their edges. |
