Though the species is known to have been cultivated in’ 
this country, at the Chelsea Garden, by Miller, as far back 
as 1752, yet it proves still to be a very rare plant in 
our collections, where, as we are told, it had never blos- 
somed. Mr. Herbert, to whom this publication owes many 
rare and curious plants, and who has paid peculiar attention 
to the study and collection of the species of the present 
genus, raised the plant in his hothouse at Spofforth, and 
succeeded in bringing it to flower. The specimen from 
which the drawing has been made, was sent by his directions 
in February last; but the large bractes which belong to it, 
and are naturally destined a fall as soon as the flower is
