HOG WEED (Heradenm Sphondylium, L.) 



The fruits split apart when ripe, and they are winged, and thus 

 aided in dispersal by the wind, and, being semi-detached when ripe, 

 they are easily blown away. 



Hogweed grows in different types of soil, being a sand-loving plant, 

 growing in a sandy soil, or a humus-loving plant, and growing in humus 

 in woods, and in sandy loam. 



Two microscopic fungi infest Hogweed, P^lcc^n^a pimpinellcz and 

 Protomyccs macrosporus.
