| Term | Synonyms | Category | Limitation | Definition |
|---|---|---|---|---|
| inflexed | orientation | Bent adaxially at some point along its length. | ||
| inflorescence 1 | architecture | Mode or progressive pattern of bearing flowers; most appropriately described using adjectival terms. | ||
| inflorescence 2 | STRUCTURE | The basic architectural unit of the flower-producing portion of a plant; comprising one or more flowers, their associated supporting axes (peduncles, main axes, branches and pedicels), if any, and the appendages thereto (bracts, bractlets or bracteoles or prophylls, involucres, involucels, and glumes), if any; delimited by the insertion or gradation of a single peduncle, peduncle cluster, pedicel, pedicel cluster, or sessile flower, as the case may be, directly upon or into some proximal vegetative structure not of one of these types; depending upon the type(s) of flowers included, may be bisexual (all flowers bisexual), staminate (all flowers staminate), pistillate (all flowers pistillate), sterile (all flowers sterile), or mixed (two or more types of flowers present); most appropriately described using nominative terms. | ||
| infrabracteal | insertion | Upon the axis directly below a bract insertion. | ||
| infrabracteal | position | Upon the axis directly below a bract insertion. | ||
| infrafoliar | insertion | Upon the stem directly below a leaf insertion. | ||
| infrafoliar | position | Upon the stem directly below a leaf insertion. | ||
| inframedial | insertion | Slightly below the middle of the structure in point. | ||
| inframedial | position | Slightly below the middle of the structure in point. | ||
| infrapetiolar | insertion | bud | Axillary and surrounded by the petiole base at maturity. | |
| infrapetiolar | position | bud | Axillary and surrounded by the petiole base at maturity. | |
| infructescence 1 | STRUCTURE | A mature (fruiting) inflorescence (static sense). | ||
| infructescence 2 (not recommended) | = coenocarp, multiple fruit, syncarp; > fig, syconium | STRUCTURE | A compound fruit derived from the connate or coherent ovaries and accessory tissue(s), if any, of two or more adjacent flowers. | |
| infundibular | = funnelform, funnel-shaped | solid shape | perianth, calyx, corolla | Having a narrowly obconic tube and a spreading limb, the transition between them smooth. |
| insectivorous | < carnivorous | nutrition | plant, structure | Capturing insects, digesting their tissues by means of exoenzymes secreted by specialized cells or tissues, and assimilating the digested substances as nourishment, especially for nitrogen. |
| insect-pollinated | = entomophilous | reproduction | plant, strobilus, flower | Having the pollen normally transported between strobili or flowers by insects. |
| insertion | CHARACTER | Mode or locus of attachment of a structure to some dissimilar bearing structure. The lexicons relating to insertion and position overlap to a great degree, since these two morphological concepts are often inseparable in practice. Also overlaps conceptually with arrangement, habit, orientation, and shape. | ||
| integument | STRUCTURE | A distinct layer of tissue that encloses and serves to protect the other tissues of an organ, especially a seed. | ||
| integumentary | derivation | aril | Produced from or a modification of one or both seed integuments. | |
| intercostal | insertion | Between the costae. | ||
| intercostal | position | Between the costae. | ||
| internodal | insertion | Upon or otherwise directly associated with the internodes. | ||
| internodal | position | Upon or otherwise directly associated with the internodes. | ||
| internode | STRUCTURE | Any portion of a stem between two successive nodes. | ||
| interpetiolar | < nodal | insertion | Upon the stem between the bases of opposite leaves. |
