cies. According to Schrader's definitions our plant, if it 

 be one of the three, must certainly be pinnata ; being the 

 only one that has a sulcate hispid stalk, that of both the 

 others being smooth. Pursh and Willdenow in his species 

 plantarum, both refer to Morison's Jig. 53 for laciniata, 

 and to Jig. 54 for digitata, yet the latter is a mere copy of 

 Cornuti's figure referred to by both authors for laciniata. 

 Willdenow in his Enumeratio refers to his former character 

 of digitata as a synonym of pinnata, excluding the synonyms 

 of Aiton and Morison, the latter of which we are inclined 

 to consider as a synonym of our plant, though the same as 

 Cornuti's figure referred in the Hortus Kewensis to laciniata.
