Native. Septal, &c. (parasitic). In illustrating the dis- 

 tribution of this species it has appeared proper to reject all 

 the habitats where " C. europaea," so called, is expressly 

 stated to grow on flax or on clover ; the presumption being 

 very strong that the species really intended in such cases 

 was C. Epiliuum or C. Trifolii.
