Study Set Content:
attached alternately or in a spiral along a stem with one leaf per node
Alternate arrangement
regions between nodes
Internodes
leaves of string-of-pearls
Globe-shaped succulent
two leaves attached at each node
Opposite arrangement
leaves of a yew
Linear leaves
lobed leaf of an oak
Pinnately veined
3 or more leaves occur at a node
Whorled
secondary veins bending toward apex
Arcuate
Arrangement of veins in a leaf or leaflet blade.
Venation
one primary vein called the midvein which is included in a large midrib; secondary vein branch from the midvein
Pinnately veined
several primary veins fan out of the base of the blade. They are more or less parallel to one another in monocots and diverge from one another in dicots
Palmately veined
smaller veins forming a network
Reticulate
secondary veins paired oppositely
Pinnate
in pellate leaves, veins radiating
Rotate
small-veins connecting secondary veins
Cross-venulate
veins aligned mostly along long axis of leaf
Longitudinal
veins branching symmetrically in pairs
Dichotomous
several primary veins diverging from a point
Palmate
veins arranged axially, not intersecting
Parallel
Branching arrangement of veins in dicots is called
netted or reticulate venation
