Found by Mr. Douglas, in 1826, in fissures of moist rocks in the interior 

 of Columbia in North-west America. These specimens have the leaves hispid 

 on both sides, the segments but little divided, and narrowed at their base. 

 In other specimens, gathered in shady moist woods on the north-west coast, 

 named H. ccelestlnum by the same collector, tlie leaves are larger, with broader 

 segments, much more cut, and the flowers fewer, differences naturally attri- 

 butable to the locality. Again, the same plant occurs in the Californian col- 

 lection, but with the leaves much more hispid on the upper surface, and 

 covered with a whitish do^^m underneath.
