plane shape |
|
CHARACTER |
|
Overall two-dimensional form or aspect(s) thereof. Overlaps conceptually with architecture, arrangement, habit, insertion, orientation, and position. |
pseudoterminal |
|
position |
|
Only apparently terminal; originally subapical but displaced toward the apex by differential growth during development. |
prolate |
|
solid shape |
|
Symmetrically elongate parallel to the developmental or polar axis. |
hemiparasitic |
|
nutrition |
plant |
Partially parasitic; facultatively heterotrophic to a limited degree and capable of obtaining a portion of its essential nourishment directly from other living organisms, to which no reciprocal benefit accrues. |
galea pl. galeae, galeas |
|
STRUCTURE |
|
A galeate (galeiform, helmet-shaped) sepal or petal in a zygomorphic calyx or corolla, differing markedly in shape from and sometimes partially enclosing the other sepals or petals. |
rank |
|
FEATURE |
|
A sequence of lateral structures arising from the same axis at successive points along its length and diverging from it in the same direction. |
haplomorphic |
|
architecture |
flower |
Having the members of each set of basic floral structures numerous and spirally arranged, the flower hemispheric to conoidal overall. |
quincunx |
|
aestivation |
|
Imbricate in one whorl of five members, two wholly exterior, two wholly interior, and one partially exterior and partially interior. |
ridge |
|
FEATURE |
|
A very narrow, elongate, relatively low protrusion; esp. on fruits in Apiaceae (Umbelliferae). |
calyptrate |
|
architecture |
|
Having or constituting a calyptra. |
homogamous 2 |
|
reproduction |
plant, inflorescence |
Having flowers that do not differ in sexual constitution. |
internode |
|
STRUCTURE |
|
Any portion of a stem between two successive nodes. |
aciculate |
|
coloration |
|
Having fine, irregularly oriented, straight streaks of contrasting hue and/or intensity. |
indusium pl. indusia |
|
STRUCTURE |
|
A protective membrane that is an outgrowth from the epidermis and covers a sorus during its maturation; in Polypodiophyta. |
laevigate 1 |
|
relief |
|
Very smooth. |
semicircular |
|
arrangement |
bundle scars |
Forming an incomplete circle, like the letter C. |
clinandrium pl. clinandria |
|
FEATURE |
|
The cavity in a floral column (gynostemium) within which the anthers are borne. |
solitary 1 |
|
arrangement |
|
Disposed singly, each remote from any others. |
simple-craspedodromous |
|
venation |
|
Having a midvein that branches to either side along the length of the lamina, the secondary veins and their branches all running toward and terminating at the margin. |
connective |
|
STRUCTURE |
|
The tissue between and joining the laterally opposed thecae of an anther, connecting them with the distal end of the staminal filament when the latter is present. |
ligulate 2 |
|
architecture |
floret |
Bisexual with a zygomorphic corolla; in Asteraceae (Compositae). |
connivent |
|
arrangement |
|
Converging and distally contiguous; esp. arcuate stamens with anthers contiguous. |
leaf-opposed |
|
insertion |
|
Nodal and directly opposite the leaf. |
commissure |
|
FEATURE |
|
Precisely, the joint or common boundary between the facing surfaces of two coherent or mutually appressed structures such as mericarps or stigmas, but traditionally (though imprecisely) applied to such a facing surface itself. |
mamilla pl. mamillae |
|
STRUCTURE |
|
A nipple- or teat-shaped protrusion. |
