Chamaemorus chamaentorus (L.) Rubus chamaemorus L.

 The type is designated as Pyrola unifiora L. This is the type 

 also of Moneses Salisb. (182 1), and of Bryopthalmum E. Meyer 

 (1839). 

 Monathium uniflorum (L.) Pyrola uniflora L. Moneses grandi- 



flora S. F. Gray. 

 Monathium reticulaium (Nutt.) Moneses reticulata Nutt. 



66. — Helictonia Ehrh., 1. c. 

 The type is designated as Ophrys spiralis L., Hence Ibidium, 

 Gryostachys and Spiranthes are all synonyms. It has 

 been pointed out by Niewland (Am. Mid. Nat. 3: 132. 1913) that 

 Bauhin's name for this genus, Triorchis, has teen properly published 

 by Petiver in 1764, and is therefore the earliest generic name, since 

 1753' for this orchidaceous genus which has been so variously 

 designated within the past twenty years. To Doctor Niewland's 

 treatment I would add the following species: 

 Triorchis vernalis (Engelm. & Gray) Spiranthes vernalis
