Term Definition
Leaf venation brochidodromous Referring to a type of leaf venation in which the secondary veins do not terminate at the margin but join to form a series of prominent arches that form a submarginal nerve; for example, in many Myrtaceae. Based on Hickey, 1973. For more information about leaf venation see Ellis et al, 2009. Leaf venation brochidodromous
Leaf venation brochidodromous Secondaries joined together in a series of prominent arches. Based on Hickey, 1973. For more information abouit leaf venation see Ellis et al, 2009. Leaf venation brochidodromous
Leaf venation brochidodromous festooned Referring to a type of leaf venation in which the secondary veins do not terminate at the margin but join to form a series of prominent arches that form a submarginal nerve and, in addtion, the secondary veins possess closed loops toward their apices. Based on Hickey, 1973. For more information about leaf venation see Ellis et al, 2009. Leaf venation brochidodromous festooned
Leaf venation camptodromous Referring to a type of leaf venation in which the secondary veins do not terminate at the margin; in one type each secondary vein connects with the seconday vein above it (brochidodromous) and in the other type the secondary veins do not connect with the secondary vein above it (eucamtodromous). Based on Hickey, 1973. For more information about leaf venation see Ellis et al, 2009. Leaf venation camptodromous
Leaf venation camptodromous A type of leaf venation in which the secondary veins do not terminate at the margens Leaf venation camptodromous
Leaf venation campylodromous Referring to a type of leaf venation in which a series of more or less equal primary veins originate from a common point at the base, arch upward, and reunite toward the apex; e.g., species of Aristolochia (Aristolochiaceae). Leaf venation campylodromous
Leaf venation cladodromous Referring to a type of leaf venation in which the secondary veins branch freely before they reach the margin. Based on Hickey, 1973. For more information about leaf venation see Ellis et al, 2009. Leaf venation cladodromous
Leaf venation eucamptodromous Referring to a type of leaf venation in which the secondary veins do not reach the margin and do not form a series of prominent arches. Based on Hickey, 1973. For more information about leaf venation see Ellis et al, 2009. Leaf venation eucamptodromous
Leaf venation eucamptodromous Secondaries upturned and gradually diminishing apically inside the margin but not connecting to the secondary above it. Based on (Hickey, 1973. For more information about leaf venation see Ellis et al. (2009). Leaf venation eucamptodromous
Leaf venation flabellate Referring to leaf venation with several to many fine basal veins that spread out from the base like a fan and divide somewhat toward the apex. Based on Ellis et al., 2009. Leaf venation flabellate
Leaf venation hyphodromous Referring to a leaf blade with all but the midvein absent or not visible because the leaf blade is too fleshy for them to be seen. Leaf venation hyphodromous
Leaf venation imperfect acrodromous Referring to a type of leaf venation in which two or more primary or strongly developed secondary veins arch upward from or above the base and do not converge at the apex. Based on Hickey, 1973. For more information about leaf venation see Ellis et al, 2009. Leaf venation imperfect acrodromous
Leaf venation mixed craspedodromous Referring to a type of leaf venation in which some of the secondary veins terminate at the leaf margins and the remainder of the secondary veins do not, e.g. half of the secondary veins are craspedodromous and the other half camptodromous. Leaf venation mixed craspedodromous
Leaf venation perfect acrodromous Referring to a type of leaf venation in which two or more primary or strongly developed secondary veins arch upward from the base or above the base and converge near the apex. Based on Hickey, 1973. For more information about leaf venation see Ellis et al, 2009. Leaf venation perfect acrodromous
Leaf venation reticulodromous Referring to a leaf venation type in which the secondary veins form a network of veins soon after departing from the midrib. Based on Hickey, 1973. For more information about leaf venation see Ellis et al, 2009. Leaf venation reticulodromous
Leaf venation simple craspedodromous Referring to a type of leaf venation in which all of the secondary veins terminate at the leaf margins. Leaf venation simple craspedodromous
Leaf venation suprabasal acrodromous Referring to a type of leaf venation in which two or more primary or strongly developed secondary veins arch upward from above the base. Based on Hickey, 1973. For more information about leaf venation see Ellis et al, 2009. Leaf venation suprabasal acrodromous
Leaf venation suprabasal actinodromous Referring to a type of leaf venation in which three or more primary veins diverge radially from a single point above the point of attachment of the petiole. Leaf venation suprabasal actinodromous
Leaflet A division of a compound leaf. Leaflet
Leaflets alternate Leaflets not placed along the rachis of a pinnately compound leaf directly opposite one another. Leaflets alternate
Leaflets opposite Referring to leaflets placed along the rachis directly opposite of one another. Leaflets opposite
Leafstalk In legumes, the main axis of the leaf from its attachment to its apex; i.e., the petiole plus the rachis. Leafstalk
Legume A fruit that is derived from a single carpel, dehisces along two sutures, and is usually dry and several-seeded. Although most species of the legume family possess legumes, a number of them do not (e.g., species of Andira). Legume
Legume family Informally, a member of the legume family sensu lato (Fabaceae). Some species of legumes are indehiscent.
Lemma The lower of the two bracts that enclose the floret of the Poaceae, located above the glumes. Compare with palea. Lemma
