bristles of equal thickness on each side, giving to them a pal- 

 mate appearance ; indeed the bristles resemble in miniature 

 the ringers of a person's hand, the hand itself being repre- 

 sented by the petals. In C. Candolliana there are never more 

 than three bristles, which are much thickened at the apex, 

 and taper towards the base. 



Of Dr. Wallich's n. 4875, 1 have also seen (in Herb. Hook.) 

 the letter b from Penang ; but it is without flower or fruit. 

 It is probable that several species of the genus remain to be 

 described, and on that account I have given a fuller specific 

 character to both the above than was otherwise necessary.
