prominent angles, about half as long as the leaves. 

 The sepals form a tubular structure with four to five 

 teeth. The petals are small, four to five, with long 

 claws and spreading limb. The capsule is 3-angled. 

 enclosed in the persistent calyx, 3- to 5-valved. The 

 seeds are very small, oblong, with a linear raphe, 

 and the seed-coat is hard, thin, and brittle. The 

 embryo is straight, surrounded with albumen. 



The Sea Heath flowers in August. It is a perennial 

 undershrub, and, as a creeping plant, reaches no 

 height. 



The style is slender and forked, and the stamens 

 are in two whorls of six united below by the stalks. 

 The anthers are versatile. The flowers are dicho- 

 gamous, stamens and stigma ripening at different 

 times. The flowers are bisexual and regular. In all 

 respects cross-pollination is favoured if insects visit 

 the plant, but they do not seem to do so frequently. 



The capsule being enclosed in the calyx may, 

 when ripe, be wind-dispersed. 



The only names are Frankwort and Sea Heath.
