FLORA OF JERSEY. 105 



Polygalaceae. 



1. POLYGALA L. 



1. P. SERPYLLACBA Weihe. (P. DEPEESSA Wend.) 



Native. Common on heathy hillsides and cliffs. April 



onwards. 



Guernsey. Sark. Common on siliceous soils in France. 



Distinguished by (1) the low, trailing growth ; (2) the oppo- 

 site (or sub-opposite) intermediate leaves ; (3) the marked 

 prolongation of the flowering branches beyond the raceme, 

 which thus becomes lateral. Flowers white, pink or blue. I 

 have never seen typical P. vulgaris L. in Jersey, as was to 

 be expected of a plant which affects calcareous soils, but Mr. 

 Marquand records it somewhat doubtfully from the other 

 Islands. P. oxyptbea Reich, seems hardly to deserve serious 

 consideration.
