Heterotropa parviflora ; foliis solitariis cordatis albo-maculatis siivu prof undo 

 angusto, floribus solitariis bracteatis, perianthii urceolati tubo supra medium 

 constricto iuferue ovali- ventricoso, limbi laciniis late ovatis, bracteis flore

Received through the kindness of Henry Edward Hoey, Esq., 

 of Yokohama, Japan. At first, we supposed it to be identical 

 with the Heterotrojja asaroides of Morren and Decaisne, in 

 ' Annales des Sciences Naturelles/ 2nd Series, vol. ii. p. 314, 

 1. 10. But the flowers are half the size of that, almost veined in 

 the bracts, quite different in the shape of the perianth (broad 

 turbinate in the base of the tube in that), and with quite diffe- 

 rent stigmas. I cannot therefore do otherwise than describe 

 it as a new species. 



I am aware that Messrs. Morren and Decaisne unite the 

 genus Heterotrojja with Amrum, and they are probably correct 



o doing
