 Another similarity between "Gillenia" and Maleae is susceptibility to "Phragmidium" fungus.Differences between "Gillenia" and Maleae include the chromosome number and the latter being solely woody pome bearing plants, while "Gillenia" is herbaceous and has a dry follicular fruit.The name "Porteranthus" (Britton ex Small), named for Thomas Conrad Porter, has sometimes been used for this genus.
