ringed |
|
relief |
bark |
Fissured, mainly horizontally, with at least some of the fissures individually encircling the stem more or less completely. |
|
…adelphous |
|
architecture |
flower, androecium |
Having two or more distinct sets of stamens, the sets differing from one another in the arrangements, insertions, positions and/or morphologies of the included stamens, the number of sets indicated by the prefix, at least one set with two or more members; as in diadelphous, monadelphous, triadelphous. |
|
leaf-opposed |
|
insertion |
|
Nodal and directly opposite the leaf. |
|
pliestesial |
|
duration |
plant |
Perennial and monocarpic, living several to many years before reproducing sexually, dying promptly thereafter. |
|
branchlet |
|
STRUCTURE |
|
A branch of the highest or ultimate order. |
|
oblate |
|
plane shape |
|
Symmetrically elongate and broader than long perpendicular to the developmental or polar axis. |
|
deciduous 2 |
|
habit |
plant |
Perennial and having all leaves separating and falling away during a particular portion of the yearly cycle, especially the autumn or the dry season, between growing seasons. Semantically, this term is properly applied only to the entity that falls, not to the structure that it separates and falls from; in traditional usage, though, the term has been applied to trees and other perennial plants that shed all their leaves at some time during the yearly cycle. |
|
caducous |
|
duration |
structure |
Deciduous upon or immediately after emergence, with little or no evident senescence beforehand. |
|
diaphragmed |
|
architecture |
pith |
Uninterrupted by cavities but heterogeneous in texture at axis maturity, with sectors of spongy tissue separated by relatively thin transverse plates of denser tissue that occur at the nodes or are otherwise regularly spaced along the axis. |
|
anisopetalous |
|
architecture |
flower, perianth, corolla |
Having petals unequal in size and/or shape. |
|
hydathode |
|
STRUCTURE |
|
A multicellular, anatomically distinctive structure located within a leaf at its periphery, its cells surrounding a central canal that opens to the exterior, through which water is actively discharged under humid conditions that impede the rate of transpiration; this liquid discharge is termed guttation. |
|
secund 2 |
|
architecture |
stem |
Having the petioles oriented such that the main bodies of all the leaves lie to one side of the bearing stem. |
|
tubular |
|
solid shape |
|
Cylindric or attenuate-cylindric overall and with a hollow interior open at one or both ends. |
|
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). |
|
pseudostem |
|
STRUCTURE |
|
A structure that resembles a stem but is not part of the axial system of a shoot, lacking anatomical differentiation into nodes and internodes. |
|
straight |
|
course |
|
Lacking significant curves or bends. |
|
collateral |
|
insertion |
buds |
In pairs within or immediately straddling the leaf axils, the members of a pair lateral to one another. |
|
incurved |
|
orientation |
|
Curving adaxially. See also decurved. |
|
dovetailing |
|
habit |
trichome |
Papillate and serving to hold a surface to the opposing one of an appressed structure by interlocking with others on the opposing surface; sometimes furcate. |
|
aristate 2 |
|
apex |
pappus scale |
Terminating in one or more awn- or bristle-like appendages. |
|
free |
|
fusion |
dissimilar structure(s) |
Not fused with or joined to any other dissimilar structure(s). |
|
pyxis pl. pyxides |
|
nominative |
fruit |
Like a capsule but circumscissile, the one or more seeds being released from the locule(s) upon separation of the distal, cap-like portion of the pericarp. See also diplotegium. |
|
subpetiolar |
|
insertion |
|
Just below the point of petiole insertion. |
|
intercostal |
|
position |
|
Between the costae. |
