and frequently in company, and are not readily distinguished, 

 except by the colour of the flowers. But, as Prof Hooker 

 justly remarks, in H. ciliaris, the lip is more thickly fringed, 

 and the upper petals are likewise fringed ; whereas in H. ble- 

 phariglottis these are quite naked.

Root fasciculated. Stem 1 — 2 feet high, multangular, leafy. Leaves 

 lanceolate, upper ones shorter. Spike 2 — 4 inches long, somewhat 

 sparsely flowered. Bractece linear-lanceolate ; the lower ones equal to 

 the flowers, the uppermost shorter. Flowers white. Sepals ovate 

 obtuse, the lateral ones somewhat oblique, spreading or reflexed ; the 

 upper one connivent with the linear-lanceolate petals, and somewhat 

 arched over the column. Lip linear, entire obtuse, dilated at the base. 

 Spur as long as the lip, a little shorter than the ovarium ; obtuse, some- 

 what incurved. Cells of the anther subdistant at the base. Glands of the 

 pollinia distinct. 



Hab. In deep sphagnous swamps, not uncommon in the 

 northern part of the state. I have also seen specimens from 

 Quebec, and from Sault St. Marie. Flowers June — July. 



Obs. The plant described above agrees entirely with Or- 

 chis dilatata of Pursh, but is not the plant commonly known to 

 our botanists under that name. The true O. dilatata, as I con- 

 sider it, has white flowers with the lip linear and distinctly di- 

 lated at the base. The plant referred to this species in Tor- 

 rey's Compendium, Beck's Flora, &c. has greenish flowers, 

 with the lip lanceolate, acutish, not distinctly dilated at the 

 base, and cannot be distinguished from O. hyperhorea of Pursh. 

 I have seen no specimens corresponding in all respects with 

 the figure and detailed description of the Habenaria dilatata of 

 Hooker, Exot. Fl. I. c. His plant appears to connect this with 

 the succeeding species.
