This order includes a considerable number of Australian plants, referable to the 
following genera; amongst the tribe Lasiopetaleae : to Guichenotia, Thomasia, Rhyn- 
chostemon, Leucothamnus, Lasiopetalum, Asterochiton, Corethrostylis, Lysiosepalum, 
Sarotes, Keraudrenia, Seringia; amongst the tribe Buettneriacese : to Rulingia, Com- 
mersonia, Hannafordia, Achilleopsis and Abroma; amongst the tribe Hermanniese: 
to Waltheria, Dicarpidium, Melocliia, Ridleya; amongst Domheyacese: to Melhania 
and seemingly also to Pterospermum. 
Affinity brings this order in near contact with Malvaceae and Sterculiacese, and 
also, as well pointed out by Dr. Steetz, with Tremandrese.
