with leafy concave bracts. The lip is strikingly different from that of 
any other species.

E. foliis ovalibus acuminatis multinerviis basi angustatis, spicà brevi ses- 
sili, bracteis lineari-lanceolatis acuminatis floribus dupló longioribus, 
hypochilio subrotundo, epichilio ovato acuminato plano. 
Hab. in India septentrionali; prov. Mussooree, Royle, (v. ic. pict. penes

Apparently distinct from E. macrostachya in its short dense spike of green 
flowers, which is not elevated on along scape. I only know it from Dr. 
Royle's drawings. It approaches the species just mentioned in the details 
of structure, but is a very different looking plant. 
8. ErirPAcTIS americana. Lindl. in Ann. nat. hist. 4. 385. 
E. foliis 5-nerviis inferioribus ovalibus superioribus ensiformi-lanceolatis, 
bracteis foliaceis floribus multó logioribus, racemo laxo sursüm pubes-

minore ovafo acumine latà membranaceà. 
Epipactis gigantea. Douglas MSS. Hooker. Fl. Bor. am. 2. 220. t. 202. 
Hab. in America septentrionali; Mexico, juxta Rio del Salto cataractas, locis 
umbrosis, Aprili, Hartweg ; Nova Albion, Douglas ; Texas, Drummond ; ` 
(hab. s. sp.) 
This species, which is the only Epipactis found in America, has a range 
from the Rocky Mountains to Mexico, through all which space it main- 
tains its character. I owe my friend, Sir Wm. Hooker, an apology for 
not adopting the name he found among Douglas's plants ; but as there is 
nothing remarkable in the stature of the species generally, I trust he will . 
admit my name, which was published before I had received the 11th part 
of the Flora Boreali-americana. The species has fine large flowers like 
E. consimilis, to which it approaches very closely.

Although the supposed genus to which, at the instance of M. Adolphe 
Brongniart, I consented that the name of Decaisnia should be transferred, 
proves to be the same as Prescottia (see Ann. of Nat. Hist. vi.) yet I do not 
think it advisable to renew the name, because it would only create more 
confusion than already exists,
