Specimens of this beautiful plant were kindly forwarded to me, 
in April last, by Mr Henry SHEPHERD, from the collection of 
Mrs ArnoLp Harrison of Aegsburgh, near Liverpool, along 
with an excellent drawing by the same lady. Mrs Harrison 
received it two years ago from her brother at Rio de Janeiro; 
and tlie species appearing to me entirely new, I cannot do bet- 
ter than honour it with the name of an individual who has not 
only introduced this; but many other new and rare plants to 
our gardens, and who cultivates them with great success. 
Many important points divide this species from D. Bar- 
ringtonie, to which it bears a considerable resemblance.
