|
latex pl. latices, latexes |
|
SUBSTANCE |
|
A moderately viscous and sticky exudate, often milky, sometimes otherwise colored or clear. Overlaps conceptually with gum. |
|
laticiferous |
|
exudation |
|
Producing and exuding latex. |

Opening laterally, on the tangential sides. See also extrorse, introrse. |
|
latticed |
= cancellate, clathrate |
architecture |
foliaceous structure |
Having portions of the blade naturally devoid of any but vascular tissue, which forms an open lattice in those areas. |
|

= loose |
architecture |
|
Having equivalent constituent parts disposed distant from one another. |
|
leaf 1 pl. leaves |
= frond, macrophyll (not recommended), megaphyll; > frond, needle |
STRUCTURE |
|
A principal, vegetative shoot organ borne laterally from a stem node; its vascular tissues, if any, continuous with those of the stem; undergoing no significant secondary growth; usually more or less bilaterally symmetrical; comprising a distal, usually laminar blade and/or a proximal stalk (petiole) or sheath; usually a primary site of photosynthesis. |
|
leaf 2 pl. leaves |
= microphyll |
STRUCTURE |
|
A small, lateral, leaf-like enation that, evolutionarily, is not a true leaf, i.e., whose vasculature, if any, consists of only a single median strand not ontogenetically integral with the vasculature of the bearing stem and not associated with leaf gaps in the stele of the stem; in Psilotophyta, Lycopodiophyta, Equisetophyta. |
|
leaf scar |
|
FEATURE |
|
A scar on a twig or stem due to abscission of a megaphyll; having an outline like that of a transverse section through the base of the petiole, sheath, or blade that was inserted there. |
|
leaf-bearing |
= foliate |
architecture |
plant, axis |
Bearing leaves. |
|
leafless |
= aphyllous |
architecture |
plant, axis |
Not bearing leaves. |
|
leaflet |
> pinna, pinnule |
STRUCTURE |
|
One of the one or more distinct, leaf-like, first- or higher-order divisions of a compound leaf blade; stalked (petiolulate) or sessile; borne upon a rachis or rachilla. |
|
…leafleted |
= …foliolate |
architecture |
foliaceous structure |
Compound with one order of the number of leaflets indicated by the prefix, arranged either pinnately or palmately; as in five-leafleted. See also conjugate, one-leafleted (single-leafleted, unifoliolate), unijugate. |
|
leaf-like |
= foliaceous |
architecture |
structure |
Resembling a leaf in shape, texture and color. |
|
leaf-opposed |
|
position |
|
Nodal and directly opposite the leaf. |
|
leaf-opposed |
|
insertion |
|
Nodal and directly opposite the leaf. |
|
leathery |
= coriaceous |
texture |
|
Moderately thick, tough, and very pliable. |
|
…leaved |
= …foliate |
architecture |
plant, axis |
Having (only) the number of leaves indicated by the prefix; as in two-leaved. |
|
leftward |
= sinistrorse |
orientation |
|
Directed to the left, relative to the direction of growth along an explicit or implicit axis of reference. See also rightward (dextrorse). |
|
legume |
|
nominative |
fruit |
Dry, septicidal, one-loculed and derived from a single, superior, simple ovary; dehiscing along two sutures, one abaxial, one adaxial; in Fabaceae (Leguminosae). See also loment. |
|
lemma pl. lemmata, lemmas |
|
STRUCTURE |
|
The proximal bract of the (usually) two that immediately subtend the flower in a grass (Poaceae) floret; the other is the palea. |
