432 73. ORCHIDACE.E. 



Descends to the coast level, or nearly so, in Ouse. 



Ascends to 100 yards, more or less, in Thames. 



Range of mean annual temperature 49 — 48. 



Native. Sylvestral, &c. Long knov^n as a native of the 

 provinces of Thames and Ouse. Other more northerly habi- 

 tats have lately been reported in those of Trent and Hum- 

 ber. By Mr. T. V. Wollaston (Phytologist i. 523) it has 

 been found "plentiful in Gate Burton Wood," Lincoln- 

 shire; and it is reported to have been discovered by Mrs. 

 Broadrick, in Hampole Wood, near Doncaster, Yorkshire. 

 While it would be satisfactory to me to obtain a verifica- 

 tion of this report, indirectly conveyed, and probably un- 

 published, the alleged habitat near Doncaster does not ap- 

 pear so unlikely as to warrant its rejection without inquiry ; 

 although, for the present, I prefer to hold it uncertain.
