Peramium pubescens (Willd.) MacM. This species seems to be 

 found only in the eastern portion of the state. It may be 

 found in dry upland woods, flowering usually in August. 

 Because of the evergreen character of the leaves this species 

 may be collected during the winter season, but of course, only 

 the root and leaves will be secured. As a whole the species is 

 infrequent. Our specimens are from Muscatine (Reppert) and 

 Johnson counties We have seen specimens from Winneshiek 

 and Jones counoies. Neottia pubescens Willd. (1805); Goodyera 

 pubescens K. Br. (1813); Peramium inibescens MsbcM. (1892).

Achroanthes unifolia (Mx.) Raf. This species seems to be 

 the rarest of the Orchid family as represented in Iowa. Our 

 single Iowa specimen was collected in low woods in Johnson 

 county. The S. U. I. herbarium h^s one specimen from John- 

 son county and two specimens from Muscatine county. The 

 Muscatine specimens were contributed by Mr. Reppert who, in 

 a note with the specimens, says, "Pound a few, once by Ken- 

 neth MacKensie, July, 1893. " It is reported from Winneshiek 

 county by Arthur, who gives the localities, Decorah andHesper.

Leptorchis liliifolia (L.) Kuntze. This species is to be found in 

 open upland woods during May and June. It is often locally 

 frequent but generally very infrequent. Our specimens are 

 from Winneshiek (Goddard), Muscatine (Reppert), Johnson, 

 and Jasper (Norton) counties. It is reported from Scott county 

 by Na.gel and Haupt in Proc. of Daven. Acad, of Sciences, Vol. 

 2. The data limits the species to the eastern portion of the 

 state. Ophrys liliifolia L. (1753); Liparis liliifolia L. C. Rich.
