Which genus of plant had more species identified with it in the past, Carissa or Aruncus?
Aruncus Aruncus is a genus of clump forming herbaceous perennial plants in the family Rosaceae. Botanical opinion of the number of species differs, with from one to four species accepted. They are closely related to the genera "Filipendula" and "Spiraea", and are native to mountainous damp woodland in temperate regions of the Northern Hemisphere. Creamy white plumes of flowers are produced above veined and toothed leaflets.
Rhaphiolepis Rhaphiolepis ( or ;) is a genus of about fifteen species of evergreen shrubs and small trees in the family Rosaceae, native to warm temperate and subtropical eastern and southeastern Asia, from southern Japan, southern Korea and southern China south to Thailand and Vietnam. In searching literature it is well to remember that the name commonly is misspelt "Raphiolepsis". The genus is closely related to "Eriobotrya" (loquats), so closely in fact, that members of the two genera have hybridised with each other; for example the "Coppertone loquat" is a hybrid of "Eriobotrya deflexa" X "Rhaphiolepis indica". The common name hawthorn, originally specifically applied to the related genus "Crataegus", now also appears in the common names for some "Rhaphiolepis" species. For example, "Rhaphiolepis indica" often is called "Indian hawthorn", and "Rhaphiolepis umbellata", "Yeddo hawthorn".
