they were placed, after having been dried, of a deep, rusty red colour, 



which also penetrated several contiguous sheets ; — and that D. rotun- 



difolia, on the same sheet, was found to possess a similar property, but 



in a much slighter degree."

3. D. Anfflica, Huds. (^great Sun-deio) ; leaves radical linear- 

 spathulate erect on very long glabrous petioles, seeds with a 

 loose chafFy coat. E. Bot. t. 369. 



On bogs in several parts of Scotland, as far north as Ardnamurchan. 

 Near Warrington, Lancashire. Bedfordshire, Norfolk, and probably in 

 other counties. F/. July, Aug. l/[. — This has much longer and narrower 

 leaves than the last, and would better deserve the name of longifolia. 

 But that character has never been considered (though I believe it is very 

 constant) sufficient to separate this species from the last ; and a general 

 opinion has prevailed, with myself as well as others, that the present was 

 but a variety of longifolia. Now, however, that Heyne and Mr Wilson 

 have observed the true nature of its seed, an important and invariable 

 character is established. Here the seed, as in Pijrola and Orchis and 

 in D. rotimdifolia, has a very loose, reticulated, even coat. In D. 

 longifolia the coat firmly adheres to the rest of the seed, and is rough 

 or papillose. " Embryo at the lower end of the seed, dicotyledonous."
