This, again, appears a very Protean plant in the foliage, which is entire, sinuato-pinnatifid, or deeply pinnatifid 

 with linear spreading segments. The plant varies from two to six inches long, and bears one or many scapes, all 

 the parts being more or less clothed with a soft subtomentose pubescence ; it has also been found at Cape Fan- 

 weather by Capt. King.

I have described this species partly from my own specimens, which are very imperfect, and partly from others
