Cyanostegia (Verbenaceae) is represented by four species of small shrubs all of which occur in Western Australia. Apart from C. cyanocalyx (F. Muell) Gardn. which is found in the Kimberley district, the species are confined to the outer wheat belt where their dense blue flowers form a striking feature of the spring landscape. The leaves of these species possess viscid coatings which attracted our attention, and incidental to a study of the associated diterpenoids we have isolated a number of flavones which are the subject of this communication.
