CALYCIFLOR.E 263 



The flowers bloom from May to August. The 

 plant is a herbaceous perennial, and is creeping. 



The honey is exposed. The anthers open in 

 succession, but before the last are ripe the stigma 

 matures, so that self-pollination occurs. The pollen 

 is pale yellow, and forms a pyramid. 



The fruit consists of achenes or schizocarps, which 

 when ripe are detached from the carpophore. 



White Rot is known in different districts by the 

 following names : Fairies' Table, Farthing Rot, 

 Flowkwort, Penny Grass, Rot Grass, Sheep-killing 

 Penny Grass, Shilling Grass, Penny Rot, Marsh 

 Pennywort, Sheep-killing, Sheep-rot, Sheep's-bane, 

 Water-cup, Water Rot, White Rot. 



Hydrocotyle vulgaris. — The Fig. 55 shows the 

 characteristic habit, the roots at the nodes, the peltate 

 leaves, and the minute axillary umbels of flowers or 

 fruit. 



Field Eryngo or Sea Holly {Eryngium 



campestre) . 



In having the florets arranged in heads, not umbels, 

 with spinous bracts, resembling Holly in this charac- 

 ter, the Sea Hollies differ from other Umbellifers. 



The species is not so maritime as the common 

 Sea Holly. It occurs in many parts of Britain, or 

 England, and is considered to be a recent introduc- 

 tion. But it has been regarded as wild in Kent. It 

 occurs in Ireland and the Channel Islands as an 

 introduction.
