FIG. 188. TALL BROOMEAPE (Orobanche elatior). 



The Broomrapes are a remarkable genus of plants that are parasitic upon the roots of other plants, from which 

 they obtain all their nourishment. Having no use for leaves, these are reduced to thin dry scales. This is our 

 tallest species, and about three feet in height. It is parasitic upon the roots of Hardheads (Centaurea scabiosa).
