HAIEY ST. JOHN'S 

 WOKT. 



Hyperieum hirsutum. Nat. Ord., 

 ffypericaeea:. 



HE hairy St. John's Wort, or 

 Hyperieum hirsutum, may be 

 commonly met with in woods 

 and in the rank undergrowth 

 of the copse and thicket, 

 though it seems to thrive best 

 when on a soil of chalk. J-t 

 is a perennial, and those. who 

 would see it at its best must 

 visit the localities we have 

 named during July or August, 

 when its slender spine bears 

 its terminal of brilliant yellow 

 blossoms. The root of the 

 hairy St. John's Wort is 

 brown, fibrous, and somewhat 

 up is erect and rigid, and 

 ordinarily about two feet in height, though we may 

 occasionally see specimens that exceed this. It is round in 

 erection, and on being cut through is found to be solid, 

 unlike that of its near relative, the square-stalked St. 

 John's Wort, or Hyperieum quadrangulum, where the rectan- 

 gular stalk is a prominent specific feature. The stem of the 

 hairy St. John's Wort is always more or less hairy or down}', 



woody ; 



stem thrown
