Another tall growing genus is the Silphium or Rosin- Plant. 

 There are several species ; the most remarkable is S. laciniatam, 

 the Compass Plant of the prairies, which is said to have the 

 peculiarity of turning the edges of its lower leaves north and 

 south ; but this is not observed in cultivation. This plant grows 

 from six to twelve feet high and has large yellow flowers. 

 Another showy species is S. perfoliatum or Cup-Plant ; it has 

 square stems, six to eight feet high, and numerous large flowers of 

 deep yellow color. Other very valuable species are integrifolium, 

 terehinthinaceum^ trifoliatum, Asteriscus, and asperrimum, all with 

 yellow flowers, and albijlorum with white flowers. 



The Vernonia, or Iron-weed, grows also from six to ten feet in 

 height, and has large clusters of deep purple flowers. Some of 

 the best species are Ai'kansana,, JSfoveboracensis, altissima, and 

 fasciculata. 



An early flowering plant is Sanguinaria Canadensis or Blood- 

 root, with its snow-white blossom. 



Waldsteinia fragarioides sends up at the same time a great pro-

Geum triflorum also flowers in the early season, and is followed 

 b}' curious seeds ; while G. radiatum produces its golden flowers 

 in June.

 large spikes of blue flowers, while L. splendens has the same habit, 

 and deep red flowers. 



Very ornamental are also the herbaceous species of Spiraea, such
