The author concludes his paper with the description of a new and 

 nearly-related genus, founded upon a plant which was introduced 

 from New South Wales into the Royal Botanic Garden at Kew, in 

 1823, and which is remarkable for its unenclosed embryo, and for 

 the singular appendages, similar to those of Parnassia, which are 

 seated at the inner base of the sepals. The following is the descrip- 

 tion of this interesting genus : — 



TRIPLADENIA.
