HOUSTOMA PURPUREA. 



Class, Order. 



TETRA NDHIA MONOG YNIA 



Native of dry woods from Pensylvania to 

 Carolina : with us it flowers in June and 

 July; it probably varies with deeper co- 

 loured flowers, otherwise its name is not 

 very applicable. 



We have kepi it in the greenhouse, as it 

 will scarcely endure our winters. It should 

 be potted in loam and peat, and may be in- 

 creased by dividing the root.
