Leptorchis loeslii (L.) MacM. This species is rare within our 

 limits. It occurs in hillside bogs and wet thickets and may be 

 found during May and June. Specimens before us are from 

 Muscatine (Reppert) and Emmet (Cratty) counties. Ophrys 

 loeslii L. (1753); Liparis loeslii L. C. Rich. (1825); LejJtorchis loeslii

Corallorhiza odontorhiza (Willd.) Nutt. We have collected this 

 species only on two occasions in Johnson county. It is usually 

 considered rare. In August, 1896, it was common but has not 

 been observed since. So far as we are aware this is the only 

 locality known in the state, but it probably occurs near the 

 Mississippi river. It may be found in rich upland woods where 

 there is a considerable depth of decaying leaves. Oymbidium 

 odontorhiza Willd. (1805); Corallorhiza odontorhiza Nutt. (1818).

Limodorum tuberosum L. (1753). This species is infrequent 

 in the eastern portion of the state, occurring in bogs and low 

 places during June and July. Our specimens are from Pay- 

 ette (Fink), Muscatine (Reppert), and Johnson counties; and 

 there is a specimen in the S. U. I. herbarium from Howard 

 county. Oymbidium pulchellum Willd. (1805); Galopogonpulchellus 

 R. Br. (1813).

Aplectrum spicatum (Walt.) B. S. P. This species is to be 

 found only in rich woods. Its occurrence is rather infrequent. 

 Our specimens are from Fayette (Fink), and Johnson counties. 

 Our last collection was obtained on May 26, 1898. Arethusa 

 spicata Walt. (1788); Oymbidium hyemale Willd. (1805); Aplectrum
