BIOCHEMICAL SYSTEMATICS 



major family in the classically constituted Centrospermae, Caryophyl- 

 laceae, lacks betacyanins. As noted by Dreiding (1961) this distribution 

 raises the question of whether the Caryophyllaceae are to be consid- 

 ered more advanced or more primitive than other families of the order.

 betacyanins have been found (from Dreiding, 1962 and Mabry et al, 1963).
