Which leaves of a rosehip are simple or complex, which venation and arrangement?

Rosehip leaves are odd-pinnate (when the number of leaf blades is unpaired and there is one blade at the top of the leaf), this leaf structure is complex (the presence of several leaf plates connected by one petiole). The vein is reticulate, the main vein is well defined, from which the rest, smaller ones, form a network. The arrangement of the leaves is alternate (when the leaves alternate with each other).
