of equal lengths, somewhat membranous at the base. Corolla wheel- 

 shaped, with a short tube, the limb of five mostly regular linear obtuse 

 spreading segments. Stamens fire, inserted into the ovariura, about 

 half the length of the corolla. Filaments awl-shaped, free. Anthers 

 oblong, of two cells, mostly united at the base around the style, which is 

 as long again as the stamens, bearing a club-shaped stigma, notched 

 at the extremity, with a furrow on one side of most of them. Capsule 

 of two imperfect cells, with five angles, opening at the apex with a 

 small pore. Seeds numerous, very small, attached to a central 

 placenta. 



Habitat, Dry heaths, sandy pastures, and tops of old walls ; 

 common. 



Annual ; flowering in June and July. 



From the general appearance of this plant, the student might sup- 

 pose that it belonged to the genus Scabiosa; but, upon examination, he 

 will find them very different. It has also a considerable resem- 

 blance to the natural order Composites (class Syngenesia), amongst 

 which it was placed by Linnaeus ; but this has a distinct calyx to each 

 perfect iower, elevated on a footstalk, which is not the case with 

 compositae. The flowers, however, are collected into a head, within a 

 general involucra, and the union of the anthers around the style shows 

 the near affinity it bears to that order, and it will be seen how nearly 

 allied it is to the following genus Phyteumu.

GEN. CHAR. Calyx five-cleft. Corolla wheel-shaped, in five deep
