The definitions are OK if it is clear what vein category you are talking
about. The festooned brochidodromous leaves are those that have one or
more additional sets of loops outside the main brochidodromous loops that
can be originated from secondary veins and/or tertiary veins or veins of
higher category (here is where you REALLY need to know the vein
category). In addition, when the secondary veins end in a strong vein
closely paralleling the leaf margin they form the typical "intramarginal
vein" (see for example in Myrtaceae)
