symmetric(al) 1 |
|
architecture |
|

|
Inversely trulloid. |
brachiate |
|
architecture |
axis |

CHARACTER |
|
Mode of acquiring nutrients. |
tendril |
|
STRUCTURE |
|
A slender stem branch, modified leaf, or portion of a leaf that twines about a supporting structure. |
calyptra pl. calyptrae |
|
STRUCTURE |
|
A distal hood- or lid-like portion that detaches as a unit from the remainder of the structure; esp. in some Papaveraceae the unopened calyx that separates from the rest of the flower at anthesis. |
epichilium |
|
STRUCTURE |
|
The distal portion of a labellum (lip) that has distinct proximal, distal, and sometimes also central parts; in Orchidaceae. See also hypochilium, mesochilium. |
opposite 2 |
|
arrangement |
|
Having the members of each whorl inserted directly above and/or below those of the next adjacent whorl(s). See also antipetalous, antisepalous. |
trulloid |
|
solid shape |
|
Elongate, basically square in transverse section, broadest below the middle, regularly attenuate to angular ends, all faces essentially plane. See also obtrulloid. |
elongate |
|
plane shape |
|
Longer in one dimension than in any other. |
parietal |
|
placentation |
|
Upon the inner wall surface of a unilocular ovary, thus peripheral within the locule. |
plicate 1 |
|
aestivation |
|
Valvate with each member strongly infolded longitudinally. |
foliar |
|
insertion |
|
Upon or otherwise directly associated with the leaves. |
U-form |
|
arrangement |
bundle scars |
Disposed in a truncated elliptical pattern, like the letter U. |
clinandrium pl. clinandria |
|
FEATURE |
|
The cavity in a floral column (gynostemium) within which the anthers are borne. |
full |
|
extent |
|
Reaching from the ovary wall or pericarp to the center of the ovary or fruit and from the apex to the base of its interior, thus separating adjacent locules completely. |
rhachilla |
|
STRUCTURE |
|
See rachilla. |
heterosporous |
|
reproduction |
taxon |
Producing two types of spore, microspore and megaspore, which are sexually distinct and usually different in size, each megaspore giving rise to a megagametophyte, each microspore to a microgametophyte. |
rectangular |
|
plane shape |
|
Basically four-sided, the sides more or less straight, those of each opposing pair more or less parallel, the generalized angles between adjacent sides approximately 90°. |
acicular 1 |
|
plane shape |
|
Very slenderly elongate, widest near the middle, and gradually attenuate to an acute apex and a blunter base; like the lateral outline of a needle. |
inaperturate |
|
architecture |
pollen grain |
Lacking an aperture of any type. |
husk |
|
STRUCTURE |
|
A more or less dry, hard or fibrous, simple or compound enclosure or outer layer of a seed, fruit or inflorescence. |
secund 1 |
|
architecture |
inflorescence |
Having the pedicels oriented such that the main bodies of all the flowers lie to one side of the bearing axis. |
involucre 2 |
|
STRUCTURE |
|
One or more closely proximate whorls, or a compact spiral, of bracts (phyllaries) surrounding (proximal to) the compound receptacle (torus) and florets of a capitulum (head); in Asteraceae (Compositae). |
shoot 1 |
|
STRUCTURE |
|
Collectively, all those portions of a plant body that are anatomically distinct from the root, the component axes differentiated into nodes and internodes, and branching exogenously from the former. |
