Term Synonyms Category Limitation Definition
limb 1 STRUCTURE A relatively broad portion of a syntepalous (gamotepalous) perianth, synsepalous (gamosepalous) calyx, or sympetalous (gamopetalous) corolla distal to a narrower tube, spreading outward or ascending from the tube, comprising the distinct or connate distal portions of the tepals, sepals, or petals; except in bisexual or staminate disc florets of Asteraceae (Compositae).
limb 2 STRUCTURE The portion of the corolla of a bisexual or staminate disc floret distal to the level of filament insertion; in Asteraceae (Compositae).
limp texture Lacking stiffness in in one or more dimensions, thus drooping or sagging where unsupported.
linear 1 arrangement bundle scars Disposed in a more or less straight line.
linear 2 plane shape Elongate and narrow with the sides more or less straight and parallel over most of its length.
lineate 1 coloration Having very narrow, straight, clear or colored lines that contrast with the ground color.
lineate 2 > streaked, striate relief Having very narrow, straight, shallow depressions or low protrusions. See also lineolate.
lineolate 1 coloration Finely lineate, the lines short and often irregularly oriented.
lineolate 2 relief Finely lineate, the depressions or protrusions short and often irregularly oriented.
lingulate = tongue-shaped solid shape Broadly elongate and compressed, one broad face more or less plane and the other convex, the edges rounded between them; like a tongue.
lip = labium; > labellum STRUCTURE Any substructure that resembles a lip, especially a portion of a perianth, calyx or corolla.
lip cell STRUCTURE Either of a pair of adjacent, narrow, transversely oriented, thick-walled cells bordering the pore (stomium) of a sporangium.
lipped = labiate; > bilabiate, one-lipped, two-lipped, unilabiate architecture perianth, calyx, corolla Strongly zygomorphic with connate and/or coherent members some or all of whose distal portions form one or two lip-like structures.
…lobate ? …cleft, …fid, …lobed, …parted, …partite, …segmented plane shape Having the number of lobes indicated by the prefix; as in bilobate.
…lobate ? …cleft, …fid, …lobed, …parted, …partite, …segmented solid shape Having the number of lobes indicated by the prefix; as in bilobate.
lobate ? cleft, dissected, divided, lobed, parted, partite, segmented plane shape Having one or more component sectors or peripheral protrusions that is/are delimited by concavities in the surface or margin and that is/are not proximally distinct from the remainder of the whole. The meanings of this term and its approximate synonyms sometimes have been supposed to differ according to the depth of the delimiting concavities relative to the midline or midpoint of the overall structure, and/or to the shape or proportions of the protusions or sectors; however, there has been little consistency in the applications of the various terms according to such distinctions, which are ones only of degree and are necessarily arbitrary in any case. In general usage, these terms differ only indistinctly and connotatively: cleft, lobed (or lobate), parted (or partite) and segmented tend to connote fewer protrusions or sectors; lobate usually connotes as well a generally rounded shape; dissected tends to connote more numerous sectors that are elongate and angular. See also cut (incised, lacerate, torn), laciniate (slashed).

lobe ? division, segment STRUCTURE Any generally convex, major peripheral protrusion or component sector that is delimited by concavities in the surface or margin and that is not proximally distinct from the remainder of the whole.
…lobed ? …cleft, …fid, …lobate, …parted, …partite, …segmented plane shape Having the number of lobes indicated by the prefix; as in five-lobed.

locule = cell (not recommended), chamber (not recommended) FEATURE Any structurally distinct compartment within an anther, ovary, fruit, sporangium or other organ; not necessarily having any evolutionary integrity.
