ToZaccheus Collins- Esq. of Philadelphia, to whom I owe many^ 

 ■obligations, I am indebted for fine speciments of this plant, with the 

 reference to Ventenat and Michaux. There is still some obscurity 

 about it. The capsules, as well as I can judge from them in an im- 

 filature state, arc precisely those of Saxifraga, two beaked, openi.ig 

 between the styles. The habit of the plant however is very different 

 from any Saxifraga with which 1 am acquainted, but to this genus 

 it cannot belong:.
