Orobanche Rapum-Genistae (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Orobanche rapum-genistae, the greater broomrape, is a plant species in the genus Orobanche. O. rapum-genistae contains verbascoside and orobanchoside. Broomrape or Broom-rape (Orobanche) is a genus of over 200 species of parasitic herbaceous plants in the family Orobanchaceae, mostly native to the temperate Northern Hemisphere. Some species formerly included in this genus are now referred to the genus Conopholis. The broomrape plant is small, from 10-60 cm tall depending on species. It is best recognized by its yellow-to-straw coloured stems completely lacking chlorophyll, bearing yellow, white or blue, snapdragon-like flowers. The flower shoots are scaly, with a dense terminal spike of 10-20 flowers in most species, though single in O. uniflora. The leaves are merely triangular scales. The seeds are minute, tan-to-brown, and blacken with age.
