a hybrid between latifolia and maculata in his ' Flora of Oxford- 

 shire,' under his notice of the former species (p. 294). He says : — 

 " Several forms of latifolia are found in Headington AVick Bog, 

 including a hybrid between it and maculata. This," he adds, "has 

 the solid stem and spreading leaves of iiiaculata, but the flowers are 

 very nearly those of latifolia.'" 



In connection with the above, I cannot refrain from saying that 

 the Orchis of this neighbourhood which I put to latifolia has certain 

 features which belong, according to some descriptions of the purple- 

 flowered variety of 0. incaniata, rather to that plant, though it is 

 very unlike the veritable 0. incaniata L. described by Mr. C. B. 

 Clarke in Journ. Linn. Soc, No. 120, vol. xix., pp. 206-8. This 

 latter striking plant I have seen growing near the Lizard, in Corn- 

 wall, and there only. The Plymouth plant, moreover, has its 

 leaves broadest "near the middle" rather than "near the base," a 

 character given as a special mark of latifolia, with only the lower 

 bracts exceeding the flowers. The lip, too, is only slightly divided, 

 though, on the other hand, its middle lobe, or portion, ends in what 

 is decidedly the longest point. Specimens of an Orchis that I found 

 some years ago in a bog on Crownhill Down had more of the 

 characters assigned to the purple-flowered variety of incaniata, and 

 the receipt of a specimen thence caused the late Mr. Watson to put 

 down the plant for S. Devon in Top. Bot., on my authority; so that 

 it, as well as the 0. latifolia L. [0. majalis Reich.), appears therein 

 as a S. Devon plant.
