Cypripedium concolor was discovered by the Rev. C. Parish, in 

 1859, at a place called Pya-Thonzco (The Three Pagodas) in the 

 neighbourhood of Moulmein, growing in hollows in the rock that 

 are filled with decaying vegetable matter, and subsequently in 

 other similar places ; it was not, however, introduced into 

 European gardens till 1864, when living plants were imported by 

 Messrs. Low and Co. About the same time, or shortly afterwards, 

 it was sent to the Royal Gardens at Kew by Colonel Benson, 

 from the locality in which it had been first discovered by the 

 Rev. C. Parish ; and quite recently it has been received at the 

 Royal Gardens from the Birds' Nests' Tslands near Champon, where 

 it grows on the limestone cliffs facing the sea.* The variety 

 chlorophyllum appeared among a recent importation by Messrs.
