The interesting genus Dampiera is entirely Australian, an.l is 

 remark abl}^ distinct and easily determined. 



The calyx-tube is adnate to the ovulary, which is in nearly 

 every case 1 -celled. The corolla- tube is deeply slit; the two upper 

 lobes stand well above tlie lower three, and are closely pressed 

 together, the posterior margins folding in between the lobes, and 

 forming a cavity or auricle which encloses the style and indusium, 

 and which is of various degrees of complexity in diiferent species. 

 The auricle may be taken as characteristic of the genus, for 

 although it is found in Goodenia, Velleya, and Anthotium, 3^et in 

 its highest development in those genera, it does not approach the 

 simplest form in Dampiera as regards completeness of structure. 

 The anterior margins of the upper lobe also fold under into the 

 tube of the corolla, projecting in such a manner as to cause the 

 auricles to separate w^ien an insect forces its way into the tube. 

 The three lower lobes are spreading and usually broadly winged; 

 at their base the wings are narrower and puckered up by the close 

 approach of the lobes, forming guiding lines to the nectar. The 

 throat is always glabrous and free from hairs. The anthers are 

 connate round the st3de, although in very young buds they are 

 sometimes free, but the growth of the anthers locks them together 

 later on. The style is always glabrous, and often deeply coloured; 

 the indusium is never hairy on the outside as in every other genus 

 except Brunonia (and even in this there are hairs in the early
