ORCHIDACE.E 



hundred and eighty species are valid. Spiranthes sinensis as at 

 present understood is a polymorphic species which has been 

 reported from Japan, China, Siberia, Afghanistan, India, Sunda 

 Islands, New Guinea, Australia, Tasmania, and New Zealand. A 

 critical study of specimens throughout the range may reestab- 

 lish a few of the segregates which have been described. It must 

 not be overlooked, however, that several species of the genus, 

 which have been critically examined, not only extend over a vast 

 territory, but appear to adapt themselves to a wide range of 

 climatic and soil conditions.
