calyculate 2 |
|
architecture |
flower |
Subtended by a calyculus (epicalyx). |
epibracteal |
|
position |
|
Upon the bracts, or partially adnate thereto and apparently arising therefrom. |
true |
|
derivation |
indusium |
Constituting a distinct enation from the epidermis, not simply a marginal fold of the lamina as a whole. |
bulb |
|
STRUCTURE |
|
A thickened underground perennating structure consisting of a stem with numerous closely proximate nodes bearing many tightly imbricate, thickened, often fleshy, foliaceous organs containing large amounts of stored food, usually in the form of starch; the whole usually enveloped and protected by imbricated scarious or fibrous foliaceous organs. |
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. |
cell 1 |
|
STRUCTURE |
|
Any of the basic structural/functional units that collectively or individually make up the various tissues of a plant; comprising, at least while physiologically active, a nucleus with included genetic material (chromosomes), a surrounding cytoplasm with included organelles (e.g., ribosomes, mitochondria, plastids), an enclosing membrane, and an exterior cellulosic wall. |
face |
|
FEATURE |
|
A relatively large, flat or shallowly curved portion of the external surface of a three-dimensional structure, bounded by more or less distinct topological discontinuities. |
paraphysis pl. paraphyses |
|
STRUCTURE |
|
An elongate, multicellular, sterile structure borne between sporangia within a sorus; in Polypodiophyta. |
unifacial |
|
architecture |
|
Having two opposite broad surfaces that are essentially similar in appearance. |
cleistogamous |
|
reproduction |
flower |
Having the perianth remaining closed through anthesis, preventing deposit of pollen from other flowers, thus only self-pollination possible. |
flange |
|
STRUCTURE |
|
A relatively broad, circumferential rim or ridge that protrudes laterally. |
…ciliate |
|
architecture |
|
Bearing the number of cilia indicated by the prefix. |
porosity |
|
CHARACTER |
|
Presence and disposition of vessels (pores) in wood (xylem). |
ciliate |
|
margin |
|
Having fine, hair-like trichomes (cilia) oriented in the general plane of the structure. |
porous |
|
porosity |
|
Having vessels present. |
veined |
|
architecture |
|
Having one or more orders of evident vasculature. |
rachis 2 var. rhachis |
|
STRUCTURE |
|
A main or first-order axis of an inflorescence. |
gynoecium pl. gynoecia var. gynaecium |
|
STRUCTURE |
|
The pistil(s) of a single flower together with any ontogenetically equivalent or subordinate structures present, taken collectively; the total female (ovule-producing) structural complement of a single flower. It may include one to many pistils, each simple or compound. |
column 2 |
|
STRUCTURE |
|
A fused androecium (connate stamens) closely surrounding but free from the gynoecium; esp. in Malvaceae. |
retuse |
|
apex |
|
Round overall with an obtuse terminal sinus. |
acetabuliform |
|
solid shape |
|
Transversely circular, broader than long, widest near or at the middle, relatively thin-walled, the hollow interior open distally; like a shallow bowl with strongly incurved sides. |
secondary root |
|
STRUCTURE |
|
Any root branch that originates directly or indirectly from a primary root. |
amphimictic |
|
reproduction |
taxon, plant |
Reproducing sexually. |
involucrate 1 |
|
architecture |
inflorescence |
Subtended by an involucre. |
adventitious root |
|
STRUCTURE |
|
A root that arises laterally from some part of a shoot, often from the lower portion of a main stem. |
