ROCK ROSE FAMILY. 



The VIII Order, contains but one Genus, (5 Spe- 

 cies) which bears so strong a resemblance to the 

 Poppy Family, that I will point out the difference. 

 It has a permanent Calyx of 5 Sepals, twisted before 

 opening: and the seed-vessel has several Placentas. 



The common Rock Rose (Heleanthemum Vulgare) 

 is a lovely little yellow flower, with crumpled petals, 

 and numerous stamens : with stems spreading on the 

 ground, and numerous, narrow leaves, arranged on 

 each side of them. If you press the stamena between 

 your finger and thumb, they instantly expand.
