although its flowers are tinged with pink, and its lip less abun- 

 dantly fringed." I fear both one and the other of these botanists 

 have placed too much confidence in colour in the present case ; 

 for not only is the nature of the pseudobnlb quite different 

 (multangular in D. chrysotoxum, deeply quadrangular in D. Far- 

 meri), but the curious deep velvety fringe of the lip of D. chry- 

 sotoxum, well represented both by Dr. Lindley, Bot. Reg. 1847, 

 t. 36. f. 1, and by myself, Bot. Mag. t. 5053, f. 2, has nothing 

 resembling it in the labellum of B. Farmeri. This I take there- 

 fore to be a yellow-flowered variety of the latter, and quite dis- 

 tinct from D. chrysotoxum.
