Hello David,

Taken from Flora of Thailand

cataphyll – a modified leaf which lacks a blade and in appearance corresponds to a petiole
sheath; may be used to describe other leaf types whose technical names are defined by position
rather than form, e.g., prophylls are usually of cataphyll shape in Araceae, compare, prophyll.

prophyll – the first leaf of a branch (or sympodial unit); in Araceae almost always a 2-keeled
cataphyll, often confused with cataphyll; cataphyll refers to a particular type of morphology
(reduced leaf), prophyll refers to the position of the leaf along a branch.
