PENNYWORT I5 , 



in the corolla, and the many short ovules, the plant is more liable to 

 be self- than cross-pollinated. Thrips visits but does not pollinate 

 the flowers. The anthers ripen first. 



The follicle when ripe contains many seeds, which are shaken out 

 by the wind, and this causes dispersal over a wide area. 



Pennywort is entirely a rock plant, growing on rocks, largely harder 

 granitic or siliceous rocks, and slates and hornstones. Rarely it is 

 found in the hedgerow. 



A cluster-cup fungus, Puccinia umbilici, is to be found upon it. 



Cotyledon, Dioscori- 

 des, is from the Greek 

 cot^^,le, cup, in allusion 

 to the hollow form of 

 the leaves, and the 

 Latin umbilicus also re- 

 fers to their shape and 

 character.
