 damaged dried flower, and consequently several inaccuracies 

 crept into its description, which led to its being misplaced in

Although not a very splendid plant, it is far from being 

 undeserving notice. Its very glaucous flower-stem, the snow- 

 white lip and crimson petals, lying as it were in the middle 

 of dusky brown sepals, produce a singular and pleasing effect.

 Harter, Esq. of Broughton, near Manchester, who was so 

 obliging as to forward specimens, along with a drawing by 

 Mrs. Powell, in September last. Mr. William Ashton, the 

 gardener to Mr. Harter, also deserves to be mentioned, as 

 having succeeded in flowering the plant before any one else. 

 We understand that the Orchidacese of Mr. Ilarter's collec-
