From: botanist at malesiana.com (Peter Boyce) on 2008.08.02 at 21:01:24(18318) They are cataphylls and are homologous with leaves. The first cataphyll on a new branch is a prophyll and is usually distinguishable from other cataphylls on the branch in bearing two keels along its length. Tom Ray argued that the cataphylls occurring on a fertile shoot module should be classified as different from those on a purely vegetative module and that cataphylls should also be classified on their position AND on whether the shoot module was a unit that had undergone a resting phase or not. His ideas and in particular his nomenclature were never really taken up, although Jin Murata did use the resting/non-resting differentiaton.
