ORCHIDACE^ 



Spiranthes Wrightii Ames nom. nov. Sauroglossum mono- 

 phyllum Griseb. Cat. PI. Cub. (1866) 269 as to Wright 1480, 

 excl. synonymy and Wright 621. Spiranthes monophylla Cogn. 

 in Urb. Symb. Antill. 6 (1909) 339 as to description, not as to 

 synonymy, excl. Wright 621. 



Spiranthes IVrightii differs from its nearest alhes in Cuba in 

 being monophyllous. Apparently there is a wide range of varia- 

 tion in the height of the plants and in the number of flowers 

 borne by the racemes. The sheet in the Gray Herbarium bears 

 two specimens that represent what may be taken as extremes, 

 the tallest plant being 40 cm. high with nine flowers, the smaller 

 one being 15 cm. high with only two flowers. 



From the discussion under Cranichis it is evident that the 



plant referred by Cogniaux to S. monophylla under the number 



1480 of Wright's Cuban plants is without a valid name. As 



a new name is necessary, S. Wrightii is proposed. 



Cuba, Pinal, Monte Verde, Wright 1J^80, February 19, 1859. In dense 

 woods. Whole plant tinged with dull red. Petals and sepals one-nerved. 

 Lip five-nerved, nerves reddish green.
