some descripiioii. 'Ihc first Greek (Latinized) name refers to the leaf 

 segments, which resemble a ijoat's toot. 



It is an erect plant, with a round, furrowed stem, finely furrowed 

 lens^th-ways, and hollow, bearing branches above. The leaves above 

 are 3-lobed, ami minutely toothed; below they are stalkless, and two 

 or three times v'o'^tnl, and eg^'-shaped with a prolon^xnl point. The 

 flowers are small and while, bornr in wide flat umbels, with no caly.x 



teeth, the petals unequal, 

 the fruit flattened laterally 

 with almost rounded seeds. 

 ( loutweed j^rows to a 

 hei;4ht of 2 ft. or more. 

 The llowers arc in bloom in 

 May, June, and |ul\. This 

 plant is a herbaceous peren- 

 nial and propairated by divi- 

 sion of the creeping rhiz- 

 omes, occurring' usually in 

 beds. 



The flowers are numer- 

 ous and small. The styles 

 are slender and bent back, 

 and the petals inbent at 

 the point. It is visited by 

 numerous insects — Uiptera, 

 Coleoptera, Hymenoptera, 

 and Neuroptera. 



The flowers in the pri- 

 mary umbels are complete, 

 those of the second order 

 having male florets in the middle, complete ones at the side. The 

 fruits are flattened and aided in wind dispersal, when ripe being semi- 

 detached, and jerked to a distance by the wind or passing herds. 



Goutweed is more or less a clay-loving plant addicted to a clay soil, 

 but as its distribution is largely artificial it may be found on sandy 

 loam or soil with some degree of humus in it in woods. 



The fungus J^rofoiiivccs iimcrosponis forms warts on the stem and 

 petioles, and Piicciiiia ccgopodii causes swellings on the stem and mid- 

 rib, and Plasniopora nivea is also found upon it. 



A Hymenopterous insect, Tcnthrcdo flax'a. and 2 moths, Dcprcssaria 

 applaiia and Chaitliodus illigcrellits, feed upon it.
