columna late alata. Mexico (not Brazil). The 



flowers are usually lemon-coloured, with a large num- 

 ber of lilac spots on the sepals, a smaller number on 

 the petals, a deep yellow eye, and two, or occasionally 

 four, large dark brown spots on the side of the lower part 

 of the lip, which is very much lengthened out as it ungui- 

 culate; by the latter circumstance it is chiefly known 

 from S. Wardil Many supposed varieties occur in the 

 gardens, varying in colour, and in the spotting of the lip. 

 There is one, cllled Barkeriana, i which is more remark- 

 able than the others; it looks like S. ■W™** 6 

 lip of 8. oculata, and is very handsome ; the sepals
