it under E. atrorubens ; Koch (Syn. FL Germ. 695, 1837) refers to it 

 under E. latifolia var. rtibiginosa, but as it is not given as a German 

 plant by him he may have been unacquainted with it. Petermann 

 (FL Bien. 31, 1841) gives it as a var. of E. macropodia, while it 

 appears to have been first described as a sub-species by Hoffmann 

 (Deutsch FL 182, 1800). Dalla Torre & Sarnthein are among the 

 few authors who give it specific rank as E. varians (Crantz), see FL 

 Tirol vi. (1), 542, while in Reichenbach FL Excurs. 134, 1833, it is 

 called E. viridiflora. As a variety of Epipactis latifolia it is given 

 by Irmisch in (Linnaea 16, 451, 1842), Ascherson & Graebner {Fl. 

 Nordost. 217, et FL Mittel-Europ.), Willdeman k Durand (Fl. 

 Belg. iii., 189), Corbiere (FL Normand. 551), and Coste (Fl. Fr. iii., 

 414). It may be added that assuming its distinction from Crantz's 

 varians, it appears first as a variety in Pers. Syn. ii., as Serapias 

 latifolia var. sylvestris, that it is the E. viridans var. varians of Beck 

 (Fl. Nied-Oester. 214), and of Hallier & Brand Koch Syn. iii., 2444, 

 1907, and the Helleborine latifolia var. viridiflora Briquet (Fl. Cors. 

 i., 386). I should be inclined to treat it as sub-sp. H. viridiflora. 



A NOTE ON A SECTION OF THE GENUS ORCHIS by R. B. ULLMAN 



and P. M. Hall in Report Winchester College Natural History Society, 

 p. 8-12, 1912-13. This contains some valuable notes and the suggestion 

 that there are two forms passing under Orchis incarnata. The follow- 

 ing Orchis hybrids have been found in the Winchester district by 

 members of the College most of which I have seen, and in the main 

 agree with.
