Native. Pascual or Rupestral .'' Parasitical on Thymus 

 Serpyllum. Recorded from the counties of Cornwall (Mr. 

 G. S. Gibson ; Mr. C. C. Babington), Glamorgan (Mr. 

 Gutch), York (Mr. James Ward), Fife (Dr. R. Graham, 

 &c.), Argyle (H. C. Watson, &c.), Isle of Skye (Balfour 

 and Babington), Ross (Mr. R. B. Bowman, in N. B. G.). 

 Assuming these records to be correct, the wide area of this 

 species, east and west, south and north, would connect it 

 with the British type of distribution, — or, at least, prevents 

 the reference of it to any other type ; and yet the paucity 

 of its localities brings it into strong contrast with the ge- 

 nerally distributed plants of the British type.
