Begonia Registration Handbook - American Begonia Society

Compound leaves have been included in this section for lack of a better place to put them. On compound
leaves the distance from the tip to the sinus or the radius of the leaf have no bearing on what comprises a
compound leaf. The illustration was made in the same format as the types of incisions to make comparison to
the those types easier. Just remember that a compound leaf has separate leaflets joined together at the main
petiole of the leaf. When describing compound leaves, describe a separate leaflet as you would a single leaf if
all the leaflets are identical like B. luxurians. An example would be compound, oblanceolate, dentate margin.
If one part of the leaf is compound and the other half is different describe the leaf as a whole such as lobed,
partially compound, dentate margin, etc.
