Lasiopetaleæ.
The abundance of these plants must be taken as one of the most characteristic features of the Swan River Flora, not fewer than four genera and fourteen species of this very small group being already known as its inhabitants. Of these the greater part belong to the genus Thomasia79 and are of little
