| Abstract: | Very homogeneous chemically, the genus Pittosporutn is characterized by the absence of leucoanthocyanidins, ellagic acid and phenyl-trihydroxylated compounds. This chemical definition seems to be applicable to the whole family.
Although a relationship between Pittosporum and the Saxifragaceae is not to be rejected categorically, it seems preferable, considering the polyphenols data and some anatomical features, to place Pittosporum near the Umbelliflorae rather than near the Saxifragaceae. |
