120 CLASS V. ORDER II. 



*Uraspermum iiirsutum. Hairy Uraspennum. 



U. hirsntwn ; foliis decomposiiis, folioUs jnnnatifi- 



io-iticisis ; stylis frnctus jiyramidatis, approximatis. 



Hairy; leaves decompound, leafets cut-piniiatifid; 

 styles of the fruit pyramidal, approximate. 

 &ijn. OsMORHizA BREVisTTLis. De Cand. 



This plant differs from the preceding in the taste of its root, 

 which is not sweet and anisate, but rank and unpleasant, some- 

 what like that of Aralia nudicaulis. Its more hairy aspect when 

 adult, and its more pinnatifid leaves, make it distinguishable at 

 sight. Stem, stalks and veins, clothed with divergent hairs at 

 all periods. Leaves resembling those of the foregoing species, 

 but always more deeply cut, and covered with scattered hairs. 

 General involucre of two or three leafets, deciduous. Partial 

 involucre of five oval acuminate leafets. Barren flowers central ; 

 fertile ones four or five external. Fruit stipitate and bristly as in 

 the last, but differing in the styles which are pyramidal or ovate, 

 only half as long as in the last, and appressed so as to form one 

 point, instead of diverging. — Woods on the Concord turnpike. — 

 June. — Perennial. 



The difference of this species was first pointed out to me by 

 Dr. Martyn Paine, in specimens sent from Montreal. 



131. PASTINACA. 



Pastinaca sativa. Parsnep. 



Leaves simply pinnate, pubescent underneath. 



The parsnep in its wild state is abundantly naturalized in 

 waste grounds. The root is materilly changed by difference of 

 soil. It becomes strong, acrid and virose. Stem three or four 

 feet high, smooth, angular. Umbels with yellow flowers and 

 large flat fruit. — July. — Biennial. 



132. SMYRNIUM. 



Smyrnium aureum. Golden Alexanders. 



Leaves twice ternate, leafets ovate-lanceolate, ser- 

 rate ; rays of the umbel short.
