Dahlia variabilis Desf. ; F.-Vill. 1. c. 



Cultivated forms of Dahlia are occasional in Philippine gardens, but 

 none of the species persists for more than a year or so.

 Engl. & Prantl Nat. Pflanzenfam. 4 5 (1899) 243.

"Ex insula Luconia unicum specimen reportavit ill. de Chamisso." Les- 

 sing 1. c. 



The specimen does not exist in the Berlin Herbarium, either under 

 Kleinia or Porophyllum, where I personally searched for it in 1907, and 

 which was. again searched for in 1912 by Dr. Muschler. The species of 

 this genus are all American. It is suspected that it does not properly 

 belong in Porophyllum.
