bottom, Va., and Circleville, W. Va. On the slopes south of said 

 farm, a species of Heuchera was collected. Mr. Simmons told 

 us that one of his neighbors had lost several head of cattle from 

 larkspur poison. He took us to the place where the plant was 

 supposed to grow, but we found no specimens. Very likely the 

 owner of the land had eradicated all the obnoxious plants. A 

 week later we collected on Spruce Knob, the highest mountain 

 in West Virginia. We stayed at the house of Mr. Moses Ben- 

 nett, the United States Forest Ranger, and he told us that he 

 knew where larkspur grew, and that cattle had been poisoned also 

 in his neighborhood. He took me to the place. The plant, 

 however, was not a larkspur {Delphinium) but a monkshood 

 {Aconitum) ^ with nearly white flowers. The hood is high and 

 narrow, which gives the flower some likeness with that of a 

 larkspur. 

 / Aconitum vaccarum Rydb. n. sp. 



A perennial with a fleshy root; stem 0.5-2 m. high, glabrous, 

 or sparingly pubescent, erect; basal leaves long-petioled, the 

 petioles 2-3 dm. long; blades reniform, 10-15 cm. broad, deeply 

 5-7-cleft, the divisions sub-rhombic, 3- or 2-lobed and coarsely 

 serrate, glabrous on both sides, somewhat paler beneath; lower 

 stem-leaves similar but smaller and short-petioled, the upper- 

 most subsessile and 3-cleft; racemes 2-4 dm. long, simple or with 

 a few branches below; pedicels 1-2 cm. long, strongly ascending; 

 flowers dull-white, tinged with greenish yellow without; lower 

 sepals obliquely lanceolate or ovate, 8 mm. long, ciliolate, the 

 lateral ones suborbicular, 8-9 mm. long, ciliate, the hood elongate, 

 1 cm. long, 4-5 mm. broad at the middle, rounded at the apex; 

 the nectaries of the petals 4 mm. long, equaling the claws, often 

 shaped like the petals of the garden Aquilegia; carpels 3, glabrous, 

 erect, with erect styles. 



It is related to A. reclinatum but the stem is erect, the pedicels 

 more ascending, nearly erect, and the lobes of the leaves longer 

 and more pointed. It was originally discovered by U. S. Forest 

 Ranger Moses Bennett. 



Type collected on the east slope of Spruce Knob, West Virginia,
