All leaves are directed upward, typically at an angle < 45°, often with an upward bend at the base.
Leaf arrangement is pentastichous 5/2 — this is apparent with long (> half the leaf length) internodes.
Leaves flat or may be slightly 'u'-curved (not conduplicate), normally press flat.
Stem tips with a dense cluster of erect overlapping leaves.

Leaves typically spreading away from the stem.
Leaf arrangement is distichous — often difficult to discern with short internodes
Upper leaves are strongly conduplicate, often falcate, but when pressed, leaves have often been forced flat.
Leaves not densely clustered at stem tips.
