Fox: SPECIES OF CYPRIPEDIUM. 431 



with many other species. Other forms have also been found in 

 British Indians and the islands of the East Indies^^ which ex- 

 hibit numerous remarkable characters. They are also found on 

 the Phillipine Islands'* though none have yet been found in 

 Australia."*^ None have been reported from the Hawaiian 

 Islands4 2 ^or from the West Indies and the Bahamas.*'^ 



The genus is represented in Russia, ^^ Germany ^s and other 

 portions of Europe, "* " temperate and tropical Asia, especially 

 among the Himalayas, ^ '' in the East Indies and in the western 

 continent. There "the greatest concentration of Orchids'* ^ is 

 from southern Mexico to Columbia" but this is not co-incident 

 with the area of distribution for the genus Cypripedium since 

 one species only is found ranging from Guatemala to Pan- 

 ama. * 9 



A few species are reported from British Guiana^ " and from 

 Peru, 5 1 but North America is the "home of the plicate leaved 

 Cypripedia which are confined to the temperate regions. " ^ '-^ 



The estimate as to the number of species varies with the 

 writer upon the subject, fifty-seven being listed in the Kew. In- 

 dex, 5 3 while Pfitzer notes twenty species in all, mostly reported 

 as found in northern zones. S"* Another list of forty species is 

 accepted by Bentham and Hooker, ^ s while Durand cites the 

 following: "Cypripedium L. (Criosanthes Raf.) sp. descr. ultra 

 50, Eur., Asia, temp, and trop.. Am. bor., Mexic, Guatemala. "s* 



Of this indefinite number, thirteen, which form a large pro- 

 portion in comparison with those distributed over the remain- 

 ing area, are found in North America. 



Two species, 5 7 Cypripedium hirsutum Mill, and Cypripedium 

 parviflorum Salisb. are found to cross the continent from east
