i. Echinopanax horridum (J. E. Smith) Dec. & PI. DEVIL'S CLUB. 

 Stems erect from a decumbent base, 1-4 m. high, densely prickly, leafy 

 above; leaves nearly orbicular in outline, 1.5-6 dm. broad, cordate at the 

 base with a rather narrow sinus, 3-7-lobed, with scattered prickles on 

 both sides and puberulent beneath, the lobes acute, sharply irregularly 

 serrate; inflorescence wooly, terminal, 1-3 dm. long; peduncles subtended 

 by a narrow laciniate bract; pedicels filiform; stamens about twice as long 

 as the ovate petals; fruit 4-5 mm. long, scarlet. In rocky places, Isle 

 Royale, Lake Superior (according to W. A. Wheeler); Mont, to Ore. and 

 Alaska. June. 



P. 671, after Hydrocotyle verticillata, add:

 anthers little exserted; petals yellowish or greenish, obovate, shorter than 

 the sepals; fruits 3-6, closely sessile, subglobose, 5-6 mm. long, the

 places, Mo. and Kans. to Texas. Mar. May. 



P. 677, after Musineon divaricatum, insert: 



la. Musineon Hdokeri (T. & G.) Nutt. HOOKER'S MUSINEON.
