attention of M. Carriere, a gentleman who has made this class of plants

absolutely say what position this plant ought to occupy, we can at least affirm 
that it is new, and that till now we had no knowledge that any similar kind 
existed in Europe. It is so rare in China, whence it comes, that only one indi¬ 
vidual of it has been found, The discoverer is the Abbd David. This species is
