O'RCHis. — Lamarck and Decandolle describe the lip of 

 O. laxiflora to be three-lobed, and state that the middle lobe 

 is shorter than the lateral ones, and, at the same time, emar- 

 ginate; Willdenow and Villars (under the name of O. ensi- 

 folia), and Sprengel, say that it is obcordate, but not lobed. 

 With two such different accounts, one can scarcely believe 

 that the same plant is intended. Be that as it may, Lamarck 

 and DecandoUe's description alone applies to what is found 

 in the south of France. When compared with the description 

 of O. palustris, it will be found to approach very close ; solely, 

 indeed, differing by the middle lobe of the lip being as short 

 as the lateral ones. In botli the sepals are acute, thus distin- 

 guishing these plants from O. mascula ; and, in both, the sepals 

 bent backward, not connivent, separate them from O. morio. 

 In O. palustris the labellum, or lip, as to its circumscription, 

 is round; in O. laxiflora, triangular, and attached by the 

 apex of the triangle. Though some of the above-mentioned 

 authors take no notice of the lobes of the lip, I have one 

 specimen, from Fos, in Provence, in which they are very 

 deeply marked. Merat's O. laxiflora, from the neighbourhood 

 of Paris, if his description were made from actual observation, 

 accords with that of Villars. 



O^phrys. — Smith, I observe, in the English Flora (vol. iv. 

 p. 273.), has lately added O^phrys arachnites {Jig, 165. a) to 

 our British plants. When growing, it is easily distinguished 

 from 0. aranifera (6), with which alone, in Britain, it is possible
